Juice Shop OWASP, an intentionally vulnerable web application, is widely used to train web application security concepts due to its gamified structure and realistic vulnerability simulations. Root the Box, on the other hand, offers a customizable platform for CTF competitions, enabling the creation of challenges across various categories while managing scores and participant progress. Would it be possible to integrate these two platforms to create an environment that combines Juice Shop's vulnerability exploitation exercises with Root the Box's gamification and challenge management features?
Specifically, how could these platforms be integrated to design more dynamic challenges and evaluate participants' competencies in cybersecurity, covering skills such as vulnerability identification, ethical exploitation, and problem-solving? Additionally, how could the results be structured, standardized, and interpreted to provide a clear view of participants’ knowledge levels and abilities across different domains?
Relevant answer
Answer
Initially, my idea was to combine two tools to assess students' knowledge of cybersecurity and integrate the Item Response Theory (IRT) into the system. However, at the moment, I am exclusively focused on understanding how to implement this model specifically in Juice Shop. The goal is to use IRT to more accurately measure users' level of knowledge, adjusting the difficulty of questions and challenges based on their performance.

As the global population ages, managing frailty has become a key concern in healthcare. Frailty, characterised by reduced strength, endurance, and physiological function, increases vulnerability to adverse health outcomes. One promising approach to prevent frailty is exercise, particularly strength training and aerobic activities.
However, there are still many questions about the optimal types, intensity, and frequency of exercise for different populations. Additionally, how can we best integrate exercise interventions into clinical practice and community health programs to support older adults in maintaining strength and independence?
I would like to open a discussion on the following topics:
• What types of exercise interventions have shown the most promise in reducing frailty in older adults?
• How does exercise impact other age-related conditions (e.g., sarcopenia, cognitive decline) that contribute to frailty?
• Are there specific barriers or facilitators that influence the uptake of exercise in older, frail populations?
Question:
What are the latest findings on the relationship between exercise and frailty, and how can we translate this research into practical guidelines for older adults?
Looking forward to hearing your thoughts and research insights! Thank you!
Relevant answer
Answer
Evidence overwhelmingly supports the role of exercise as a critical component in managing frailty and promoting healthy aging. Regular physical activity can improve health outcomes, enhance quality of life, and mitigate the risks associated with frailty. As public health initiatives evolve, encouraging older adults to engage in consistent and varied physical activity will be paramount for promoting longevity and well-being.
Exercise programs should be tailored to the individual's capabilities, preferences, and existing health conditions to promote adherence and safety. For frail individuals, supervised exercise programs can ensure safety and provide motivation. Involvement in community groups can help enhance social support. Addressing barriers such as fear of falling, lack of motivation, or physical limitations is essential. Educating older adults about the benefits and modifying exercises to suit their needs can help overcome these challenges.
Numerous systematic reviews and meta-analyses confirm that exercise interventions significantly improve physical performance, mobility, and quality of life in frail older adults. Research indicates that older adults who engage in regular physical activity have lower rates of frailty development and related adverse outcomes. Initiatives aimed at increasing physical activity among older adults, such as group exercises and community-based physical activity programs, have shown promising results in reducing frailty prevalence.
Incorporating weights or resistance bands to build muscle strength is vital. Guidelines typically recommend at least two days per week. Activities such as walking, swimming, or cycling can improve cardiovascular health and endurance. The recommendation is at least 150 minutes of moderate-intensity aerobic exercise per week. Stretching, yoga, and tai chi can improve flexibility, balance, and coordination, crucial for fall prevention. Combining different types of exercises in a well-rounded program is effective in addressing various aspects of frailty.
Exercise enhances muscle strength, endurance, balance, and overall functional capacity in older adults. Resistance training, in particular, has been shown to be effective in counteracting muscle loss (sarcopenia) associated with aging. Regular physical activity strengthens the body's ability to withstand illnesses and stress. This is crucial for frail older adults who may be more susceptible to health challenges. Exercise has a positive impact on cognitive functioning, delaying cognitive decline and reducing the risk of conditions such as dementia. Physical activity promotes neurogenesis and enhances brain plasticity.Exercise can alleviate symptoms of anxiety and depression, which are common in frail individuals. The social aspect of group exercise can also provide emotional support and reduce feelings of isolation. Maintaining a healthy weight is crucial for reducing the risk of frailty. Exercise helps in managing body composition, promoting lean muscle mass, and decreasing fat mass. Activities such as tai chi, yoga, and balance training are beneficial for reducing the risk of falls, which are a significant concern in frail older adults.

Hello,
As there is a lot of advocacy for strength training in women, especially around and after menopause, and a lot of women are not familiar with weight training, I wonder what are the minimum loads they need to build up to to perserve the health benefits of weights over time?
Some context: I am a recreational weightlifter myself, 35 years old. I have been training for almost 10 years at a low level. Most of my peers could not do any of the exercises or loads that I am doing. The problem is, they would also not want to - heavy load strength training is not interesting for everyone. It is even getting tiresome for me. So I am looking to learn more about what research says when it comes to minimum doses for this population.
What I currently know from research: frequency of 2 sessions per week is enough (but it will depend on volume and load, hence the question).
Thank you!
Relevant answer
Answer
Hi Hana. Low load would likely be in the 30-50% of the RM range. The amount of time for body weight likely all depends. Probs after a few weeks of training(1-3 wks). The Training status definitely plays a role. The lifter with experience would likely need higher loads and more exercises. Hope that helps!

Answer
May I add another word?
Doug is right: most, perhaps all, prominent leadership theories are behavioural. They centre on effective/ineffective leadership styles in various situations and requirements. It appears, therefore, useful to add other factors like the personality of the leader.
I would like to point to still another factor: background culture.
Great differences exist between societal cultures in various parts of the world (see e.g. the work on cultures by Geert Hofstede (2001, Cultures consequences, comparing values, behaviors, institutions and organizations across nations, London: Sage)). For instance: in some cultures, it is commonly expected that the boss acts like ‘the boss’ and subordinates have to follow his/her demands; in other societies the general expectation may be that the leader consults his/her team before deciding. Subsequently, leadership behaviour and style will be different for success in the two cases.
I am thinking of a theory comprising various levels:
(1) culture: influences from the societal level (societal culture; 1a), influences from the culture of the organisation (organisational culture 1b; this may be different from the dominant societal culture, as a particular organisation may perhaps put stress on consultation while the general culture is strict top-down); influences springing from the group of persons being led (1c; the culture of the specific department).
Next to the cultural influences, there are:
(2) the personal characteristics of the leader as well as the subordinates.
And, perhaps, we may add a third level:
(3) factors typical of the task to be performed (leadership at a university may require different leadership behaviour than being supervisor in a shoe-factory).
Especially, I would like to stress the importance of bringing in the factor of societal differences.
Long ago, I was involved in a study of work motivation comparing Bulgaria, Hungary and the Netherlands. We needed quite different models for each country. Our general conclusion was that ‘general models’ purporting to work everywhere were not adequate. For each country a ‘specific model’ was needed.
Something like this may also be required for fully understanding leadership.
May be, it is a tall order to set up a model comprising all these factors. However, even much smaller research into aspects of leadership may help our understanding of this important subject.

Frenkel exercises are performed with the intention of recovering coordination of movements.
Relevant answer
Answer
The principles of this method are concentration, precision and repetition. In this sense, the main objective is to achieve regulation of movement, so that the patient is able to carry out the essential activities of daily life. Constant repetition, smoothness of movement and precision are fundamental for the development of the method. In addition, there are a series of requirements that must be carried out for the Frenkel exercise procedure, these are:
-The patient has to see his own limbs while performing the exercise (a mirror could be used)
-Before starting the movement, the patient must have seen a demonstration of it
-The patient must pay full attention for the exercise to be effective.
-About 3-4 repetitions are done per limb
-The exercise must be repeated until it is perfect and easy. Afterwards, it will be replaced by a more difficult one.
Frenkel's method must follow a certain progression:
-The exercises are performed by altering the speed, amplitude and complexity of the exercise
-You should never do fatiguing work, nor one that involves a large muscular load, since at that point the maximum capacity for voluntary control of movement is lost.
-To progress, the patient must show perfect performance in the exercise, otherwise it is not advisable to start another one.
-Initially, it begins with those fundamental movements of great amplitude that are used in the large joints and, later, they are replaced by finer and more precise movements of the small joints.
-Reeducation exercises begin in supine position (body position lying on your back), progressing to sitting exercises (sitting body position) and, finally, to bipedalism (standing).
-The exercises are performed first with vision reinforcement and, when mastered, with eyes closed.

Narrative therapy stands as a beacon in the realm of psychotherapy, championing the notion that individuals are the ultimate authorities on their own lives. Its core premise revolves around the narratives individuals construct about themselves and their experiences. Within these narratives lie the seeds of personal growth and transformation.
In the narrative approach, therapist and client embark on a collaborative journey, delving into the intricate tapestry of stories that shape the client's perception of themselves, their challenges, and their relationships. Together, they sift through these narratives, identifying those that may be hindering progress or perpetuating oppression. Through this process, the therapist aids the client in crafting alternative, more empowering narratives, paving the way for renewed agency, resilience, and hope.
The scope of narrative therapy is broad and inclusive, offering solace and support to individuals grappling with a myriad of issues. Whether navigating the depths of depression, wrestling with anxiety, confronting the specter of trauma, or unraveling the complexities of relationships and identity, narrative therapy provides a safe harbor for exploration and growth.
At the heart of narrative therapy lies the Tree of Life exercise, a revered technique that invites individuals to chart the landscape of their life experiences, strengths, aspirations, and dreams. Through this exercise, clients unearth the roots of their heritage and culture, the branches of their hopes and aspirations, and the leaves of their strengths and resources. In the fertile soil of this symbolic tree, clients find nourishment for their journey, fostering a sense of continuity and resilience as they navigate the trials and triumphs of life.

Adopting a healthy lifestyle that includes a balanced diet, regular exercise, managing stress, avoiding harmful substances, and maintaining overall health can help support male fertility.
Relevant answer
Answer
Lifestyle factors can significantly impact male fertility. Here's how diet, exercise, and stress can affect male reproductive health:
  1. Diet: Nutritional factors play a crucial role in male fertility. A balanced diet rich in antioxidants, vitamins (especially vitamins C and E), minerals (such as zinc and selenium), and essential fatty acids (like omega-3 fatty acids) is beneficial for sperm health. Diets high in processed foods, saturated fats, and sugars may have negative effects on sperm quality and count. Excessive alcohol consumption and caffeine intake can also impair fertility. Additionally, maintaining a healthy weight is important for male fertility. Both obesity and being underweight can negatively impact sperm production and hormone levels.
  2. Exercise: Regular moderate exercise has been shown to have positive effects on male fertility by improving sperm quality, count, and motility. However, excessive or intense exercise, such as endurance training or cycling for long durations, may have detrimental effects on fertility. Prolonged exposure to high temperatures, such as in saunas or hot tubs, can also temporarily reduce sperm production.
  3. Stress: Chronic stress can adversely affect male fertility by disrupting hormonal balance, reducing libido, and impairing sperm production and quality. Stress management techniques such as relaxation exercises, meditation, and counseling may help mitigate these effects and improve fertility outcomes.
  4. Smoking and Substance Abuse: Tobacco smoking, as well as the use of recreational drugs like marijuana and cocaine, can harm sperm quality and reduce fertility. They may also increase the risk of genetic abnormalities in sperm. Exposure to environmental toxins and pollutants, such as pesticides, heavy metals, and industrial chemicals, can also negatively impact male fertility.
  5. Sleep and Rest: Adequate sleep and rest are essential for maintaining hormonal balance and overall health, which can indirectly affect male fertility. Chronic sleep disturbances or inadequate rest may impair reproductive function.
  6. Environmental Factors: Exposure to environmental factors such as radiation, electromagnetic fields, and certain chemicals (e.g., phthalates, bisphenol A) in plastics and personal care products can interfere with male reproductive health and fertility.
  7. Medical Conditions and Medications: Certain medical conditions, such as obesity, diabetes, hormonal imbalances, and infections, can affect male fertility. Medications for chronic conditions may also have side effects that impact reproductive function.

Regular assessments can help practitioners and clients identify areas that need improvement, such as balance, strength, endurance, and flexibility. This knowledge can motivate the older adult to engage in regular exercises tailored to target their specific needs. The assessment also establishes a starting point and tracks progress over time, which is particularly useful for older adults who are motivated by seeing improvement in their exercise routines, which can lead to better adherence and outcomes.
Relevant answer
Answer
Routine functional assessments in primary care can promote exercise among older adults by pinpointing functional limitations and tailoring exercise recommendations to improve mobility and strength. These assessments enhance awareness of the benefits of physical activity, leading to more personalized and effective exercise plans. Setting and tracking goals helps in maintaining motivation and addressing individual barriers, providing a clear path for progress. Referrals to specialized exercise programs can offer additional support. However, the impact of these assessments varies, depending on individual motivation, communication effectiveness, available resources, and any comorbidities that may affect exercise participation. Success relies on a comprehensive strategy involving education, customized advice, and consistent follow-up.

effects of mobility exercises?
Relevant answer
Answer
Adel Zedan is correct as to _which mobility exercise would be discussed.
And Sedhunivas Ravi is also correct in the facilitating of normal biomechanics. ( + within the ranges of normal ASL's.)
Depending on the plane of movement, which is determined first by the need of the patient, it could be many different exercises; from squats, to planks, to dips, lateral / low back extensions, pull ups, etc etc.
So, lets first define mobility. Simply put, the ability to perform ADL's without assistance in order to function normally throughout the course of our daily lives, i.e getting out of bed, getting in and out of a vehicle, getting out of a chair, driving, lifting groceries, cooking, cleaning, getting up off the floor, showering, etc etc. Many exercises can assist in these ADL's, and some have more or greater needs than others, depending on lifestyle, work(ing) habits and environments, history of exercise, health history, family needs for others, etc. So therefore, 'an effect of a mobility exercise' would be to promote and live within our daily activities without much difficulty, to specifically: maintain balance, ability to walk without assistance, overall feeling of wellbeing gained from strength, cognitive awareness, confidence, general posture, posture while sitting, etc. I'm sure we can add to this list!
This comes down to many components of the patients history and current health status, for what could be needed or recommended to strengthen their ability to move freely without pain or difficulty of performing most or all ADL's.
When incorporating strength for ADL's, I'd recommend multi-joint exercises, AKA the Big 5. Body Weight or machine Leg Presses, ( & when applicable, limited or versions of squats, and incorporating other balance type / therapeutic exercises, all depends on the patient and current fitness level and what their need and objectives are) , Latissimus Pulldowns, (Pullovers) Rowing, Chest Press, (seated dips) Shoulder Press. Botton line, always vary the exercises...........

While the primary focus of freestyle swimming is on the arm stroke and breathing technique, the legs also play a critical role in generating forward momentum and maintaining balance and stability in the water.
Recent research has shown that incorporating backstroke leg exercises into a swimmer's training regimen can have a significant impact on improving freestyle technique. Backstroke leg exercises involve working the legs in a similar way to how they are used in backstroke swimming. This includes kicking with a straight leg, pointing the toes, and engaging the hips and core muscles.
By incorporating these exercises into their training routine, swimmers can develop better balance and stability in the water, as well as increase the strength and endurance of their leg muscles. This can lead to improved propulsion and a more efficient freestyle stroke.
In addition to improving leg strength and technique, backstroke leg exercises can also help prevent injury by promoting proper alignment and reducing strain on the lower back and hip joints. This can be especially important for swimmers who may be prone to overuse injuries or who have a history of lower back pain.
Overall, incorporating backstroke leg exercises into a swimmer's training regimen can have numerous benefits for improving freestyle technique and overall performance. By developing better leg strength and coordination, swimmers can achieve greater efficiency and speed in the water, while also reducing the risk of injury.
Relevant answer
Answer
The legs play a pivotal role in generating power and maintaining balance during the freestyle stroke. By focusing on back leg exercises, swimmers can strengthen key muscle groups such as the hamstrings, glutes, and calf muscles, which contribute significantly to the kicking phase of the freestyle.
Strong back leg muscles improve the efficiency of the kicking motion, allowing swimmers to move through the water with greater force and speed. This enhanced propulsion not only increases overall swim speed but also reduces fatigue, enabling swimmers to maintain a more streamlined and effective technique for longer durations.
Also, a balanced and powerful kick provided by well-conditioned back leg muscles helps stabilize the body, promoting a horizontal position in the water. This horizontal alignment minimizes drag and optimizes the swimmer's hydrodynamic profile, resulting in smoother and more efficient strokes. Ultimately, the incorporation of back leg exercises into a training routine contributes to a comprehensive approach to freestyle development, fostering harmonious coordination of upper and lower body movements for improved performance in the water. However, the research pieces of evidence for the same are very less.

Answer
Predicting a one-repetition maximum (1RM) from a maximal voluntary contraction (MVC) for calf raises can be challenging because the relationship between MVC and 1RM can vary between individuals and depend on various factors such as muscle fiber composition, neuromuscular efficiency, and training history. However, some general guidelines and equations have been proposed in the field of strength and conditioning.
One commonly used method is to estimate the 1RM based on a percentage of the MVC.

O artigo inicia sua abordagem ressaltando a importância dos documentos digitais e a necessidade de sistemas informatizados abrangentes que abarquem todas as etapas do ciclo de vida desses documentos. Nesse contexto, é destacada a Cadeia de Custódia Digital Arquivística (CCDA), que se constitui como uma sequência ininterrupta de eventos em um ambiente digital, sujeita a auditoria por meio de procedimentos de preservação que asseguram sua integridade. A gestão de documentos é dividida entre duas plataformas: a plataforma de captura, responsável pelos estágios iniciais e intermediários, e a plataforma de preservação, que se concentra na manutenção da autenticidade a longo prazo.
Esses sistemas são concebidos com base em padrões de requisitos, sendo o Modelo de Requisitos para Sistemas Informatizados de Gestão Arquivística de Documentos (e-Arq Brasil) um dos mais proeminentes no contexto brasileiro, estabelecendo os requisitos essenciais para a implementação do Sistema Informatizado de Gestão Arquivística de Documentos (SIGAD). Adicionalmente, existem padrões que regem a implementação e auditoria da plataforma de preservação, como o modelo Open Archival Information System (OAIS) e o Audit and Certification of Trustworthy Digital Repositories (ACTDR). No Brasil, o Conselho Nacional de Arquivos também fornece orientações para a criação de um Repositório Arquivístico Digital Confiável.
A gestão de documentos requer a aplicação de ações intelectuais, metodológicas e técnicas destinadas a garantir o tratamento apropriado dos documentos arquivísticos, desde sua criação até sua destinação final. Os documentos digitais estão intimamente ligados aos sistemas informatizados e devem ser devidamente configurados e otimizados para controlar seu ciclo de vida e preservar suas características originais, mantendo também sua conexão orgânica com outros documentos.
Os autores ressaltam a necessidade de padronização dos requisitos das plataformas de acesso e difusão para assegurar a interoperabilidade com outros sistemas de arquivamento. Essa interoperabilidade é considerada uma característica essencial para a preservação a longo prazo, uma vez que possibilita a compatibilidade entre formatos de arquivo, metadados e requisitos, facilitando a conexão entre diversas plataformas no sistema de arquivamento.

What are the potential risks of individuals starting an exercise routine without the guidance of a coach, and how likely are they to experience injuries in the absence of professional supervision?
Relevant answer
Answer
Hi Kasra Khayyami, I hope you are doing well.
The answer to your question depends primarily on the outcome measure that you are interested in. For example, in older individuals, supervised balance and/or resistance training improves measures of balance and muscle strength/power to a greater extent than unsupervised programs in older adults (https://link.springer.com/article/10.1007/s40279-017-0747-6).
Furthermore, in the general population, supervised training modalities tend to elicit small/marginal benefits for other physical domains such as speed, power, function, endurance, and even for body composition adaptations. However, strength adaptations are the most favored when a supervised program is implemented (https://journal.iusca.org/index.php/Journal/article/view/101).
To the best of my knowledge, I am not aware of any evidence that supports supervised training as a way to reduce injury risk for some specific sport in comparison to non-supervised training. But I could infer that in any domain, implementing a physical training program without knowledge of the variables needed to induce proper adaptations could result in the same or higher injury risk than a supervised program.

Relevant answer
Answer
Hola, no estoy seguro de haber entendido tu pregunta, pero si te referís a las adaptaciones agúdas y crónicas del sistema cardiorrespiratorio en respuesta al entrenamiento físico, entonces la respuesta es si.
Con el ejercicio físico (principalmente de tipo aeróbico), se logra aumentar la concentración de glóbulos rojos en sangre (eritropoyesis), a causa de una elevada producción de triyodotironina, la cual estimula la liberación de eritropoyetina (EPO) por parte de los riñones, estimulando a su vez esta a la médula ósea roja del tejido óseo trabecular a crear glóbulos rojos (eritropoyesis) (Wilmore & Costill 2004), (Ciloglu et. al. 2005), (Haff & Triplett 2015), (Prieto-Macías et al. 2016), (Herrera 2017) y (Aguilar Chasipanta et. al. 2017). También la hipoxia tanto en tejidos (tisular) como en la sangre (fenómenos evidenciados durante el ejercicio), estimulan la liberación de EPO por parte de los riñones, provocando el mismo efecto (Fernández-Tresguerres Hernández et. al. 2005), (Bonilla Briceño 2005), (Morici et al. 2005), (Calderón 2007), (García & Rubio 2014) y (Trompetero-González et al. 2015). Finalmente, el ejercicio provoca liberación de catecolaminas, las cuales también estimulan a los riñones a producir EPO (Wilmore & Costill 2004) y (Saba et. al. 2017).
Lógicamente, si tenemos mas glóbulos rojos en sangre, tendremos mas transportadores de O2, lo que aumentará la captación del mismo desde los alvéolos y finalmente aumentará la concentración de O2 en sangre.
Espero haber aclarado alguna duda, saludos.

Hi Everyone! So I'm conducting research whereby there is a 2x6 within subjects repeated measures design (2 modes of exercise and 6 intensity levels).
I have conducted pre-planned comparisons (pairwise) between the lowest and highest (1 and 6) intensities for each of my outcome variables (DVs) for both exercise modes. I have hypotheses regarding each outcome variable and am unsure whether the correction should be applied for multiple comparisons as although intensity 1 and 6 are being compared in each comparison (so comparison between intensity 1 and 6 for a given DV in one of the modes), I'm not technically reusing any data points.
Thoughts on this issue are much appreciated.
Relevant answer
Answer
Hello Kieran,
In general, the larger the number of hypothesis tests, the greater the aggregate risk of committing one or more type I errors in the full set of tests.
The question is, what is the relevant full set for your study? As you describe it, you wish to compare Level_1 to Level_6 for each of two modes for each DV of interest.
If the relevant full set is a specific DV, then you're running two tests.
If the relevant full set is across the ensemble of k DVs, then you're running 2 * k tests.
Any adjustment should be undertaken with your preferred framework in mind.
Good luck with your work.

I was left with this question after reading about increased aerobic capacity conferred via fecal/microbiome replacement after exercise in humans (endurance athletes) and mice. Can we conclude the turnover rate favors these microbes that feed on the byproducts of exercise and thus increases their abundance? What is the mechanism of intestinal entry for systemic lactate produced in muscle tissue?
Relevant answer
Answer
In my opinion...
Yes, the relationship between systemic lactate and Veillonella is an interesting aspect of the exercise-induced microbiome changes. Veillonella is a genus of bacteria that can metabolize lactate, which is produced in muscles during high-intensity exercise. It has been proposed that the abundance of Veillonella increases in the gut microbiota of endurance athletes due to their high lactate production.
The idea that increased aerobic capacity is conferred via fecal/microbiome replacement stems from studies where fecal microbiota transplantation (FMT) from athletes to sedentary mice resulted in improved exercise performance in the recipient mice. This suggests that the microbiome may play a role in exercise performance, although the exact mechanisms are not yet completely understood.
The turnover rate of Veillonella may indeed be favored by the presence of lactate, as it serves as an energy source for these microbes. However, it is important to note that the abundance of Veillonella is only one factor among many that can influence exercise capacity, and further research is needed to determine the precise mechanisms and extent of this relationship.
As for the mechanism of intestinal entry for systemic lactate, lactate produced in muscle tissue during exercise can be transported into the bloodstream, where it can be taken up by other tissues such as the liver for gluconeogenesis, or by the heart and skeletal muscles as an energy source. Lactate can also be transported into the gastrointestinal lumen, although the exact mechanisms are not entirely clear. It is thought that lactate may passively diffuse across the gut epithelial cells, facilitated by monocarboxylate transporters (MCTs), or be actively transported by other transport mechanisms. Once in the gastrointestinal lumen, lactate can be utilized by Veillonella as a substrate for metabolism.
These articles are worth reading:

Nature Medicine, 25(7), 1104-1109.Este estudo analisa o microbioma de atletas de elite e identifica a bactéria Veillonella como um potencial contribuinte para o aumento da capacidade aeróbica.

Does exercise help prevent cancer?
Relevant answer
Answer
Regular exercise has been shown to have many health benefits, including reducing the risk of some types of cancer. Here are some ways in which exercise can help prevent cancer:
  1. Reducing inflammation: Chronic inflammation is a risk factor for several types of cancer. Exercise has been shown to reduce inflammation in the body, which can help reduce the risk of cancer.
  2. Controlling weight: Obesity is a risk factor for several types of cancer, including breast, colon, and prostate cancer. Exercise can help control weight by burning calories and building muscle, which can help reduce the risk of cancer.
  3. Regulating hormones: Some types of cancer are hormone-dependent, meaning they are influenced by the levels of certain hormones in the body. Exercise can help regulate hormone levels, which can reduce the risk of hormone-dependent cancers such as breast and prostate cancer.
  4. Boosting the immune system: Regular exercise can help boost the immune system, which plays an important role in preventing and fighting cancer.
  5. Improving gut health: The gut microbiome plays a role in cancer prevention, and exercise has been shown to improve gut health by increasing the diversity of gut bacteria.
It's important to note that while exercise can help reduce the risk of some types of cancer, it is not a guarantee. Other factors such as genetics, environmental factors, and lifestyle choices can also influence the risk of cancer. However, incorporating regular exercise into a healthy lifestyle can help reduce the risk of cancer and improve overall health.

There is evidence to suggest that exercise training can have a positive effect on cognitive function in individuals who have experienced traumatic brain injury (TBI). This is particularly relevant for women sportspersons, who may be at increased risk for TBI due to their participation in contact sports.
A systematic review and meta-analysis published in the Journal of Head Trauma Rehabilitation found that exercise training improved cognitive function in individuals with TBI, including improvements in attention, processing speed, and memory. The review also found that exercise training had a positive effect on mood and quality of life.
Another study published in the Journal of Neurotrauma found that a structured exercise program improved cognitive function in individuals with mild to moderate TBI. The study included both men and women, but it provides evidence that exercise can be effective in improving cognitive function in individuals with TBI.
While there is limited research specifically on the efficacy of exercise training on cognitive function in women sportspersons with TBI, the available evidence suggests that exercise can have a positive effect on cognitive function in individuals with TBI. Therefore, exercise training may be an effective intervention for improving cognitive function in women sportspersons who have experienced TBI. However, it is important to note that the specifics of the exercise program, such as the type, duration, and intensity, may vary depending on the individual's needs and level of impairment. A healthcare professional should be consulted to determine the most appropriate exercise program for a person with TBI.

Answer
Hi Matthew,
We have previously trialed using a ramp version of the sit-to-stand test whereby participants stand-sit in time to a metronome beat that gets progressivley faster. The participants also had their heart rate assessed so we could measure a “physiological sub-maximum”. Never published anything on this and not entirely sure if there is an accepted/validated test out there as this concept is relatively new. One thing inwoukd highl ight is that maximal testing online without supervision is fraught with dangers, such as syncope at maximum, cardiovascular events etc so i would advise sub-maximal testing and ensure someone else is present in the room (responsible adult/relative).

Hello,
I would like to compare the neuromuscular function of the contralateral legs via twitch interpolation technique at the same time. Since the exercise will be performed with two legs concurrently, I would like to keep the time between cessation of exercise and neuromuscular function test to be the same between the legs.
Are there any studies that have done this? Do you foresee a significant caveat?
Relevant answer
Answer
"... I would like to keep the time between cessation of exercise and neuromuscular function test to be the same between the legs."
How do you plan to do that? You can't test both legs at the exact same time. (Maybe you could, but it wouldn't be easy, and it would probably affect your results.) One leg has to be tested before the other. I suppose you could alternate back and forth as to which leg is tested first during a break from the fatiguing task.

My name is Tharushini Anandam, and I am a PhD student at Swinburne University in Melbourne, Australia. I am currently undertaking a research project as part of a Doctor of Philosophy (PhD). The purpose of my research is to increase the physical activity levels in young men with overweight or obesity by using goal-oriented strategies. They will be invited to participate in a 6-week telehealth-supported exercise program involving cardiorespiratory exercise and resistance training.
In order to conduct this study, I am seeking to recruit male participants between the age range of 18 to 34 years old who are currently with overweight or obesity (BMI 25kg/m2 to 39.9 kg/m2). Participants must be Australian citizens residing in Australia and should not have any mobility impairment. Participants will be asked to complete a pre-screening questionnaire, and if cleared, will be followed by participating in a 6-week exercise program.
It would also be greatly appreciated if you could forward this advertisement to any male friends, colleagues, or family members who meet the above criteria and may be interested to participate in a 6-week exercise program via telehealth. Thank you for your time and assistance.

Answer
There is also emergent evidence on the correlation between RPE & breathing pattern (especially respiratory frequency) showing a very close association at high relative exercise intensities. The work of Andrea Nicolò and colleagues demonstrated that central command is the primary driver or Rf especially above the RCP. Since central command activity mediates Rf and RPE, this could explain this relationship across many contexts.

Is this research question 2 experiments ( so I would thus have 2 independent variables ) or is it an experiment and control? E.g. the experiment is TENS and control is the exercise program? In both cases what are the appropriate statistical tests?
Relevant answer
Answer
From what I understand, you have two groups, i.e., one getting home exercise alone and the other getting home exercise plus TENS. Thus, you are only examining the effect of TENS (when added to home exercise). A t-test is appropriate if the data are normally distributed and you have equal variance. If you do not meet the assumptions for a parametric statistical test, you should run a Mann-Whitney test.

I have just recently started a new "weekend project" in addition to my master's studies and I am looking for a data-set. I would like to use some Operations Research to design an optimal gym schedule that conforms to a specific set of constraints.
The idea is to create a daily gym schedule that conforms to a set of constraints (e.g. time, target muscles etc) as well as a set of physiological constraints. The physiological constraints are things such as do not exercise muscle-x and muscle-y together or do not do abdominal exercises for two consecutive days etc.
However the problem I face is data, specifically a data-set (or data-sets).
Are there any open-source datasets which list an exercise, as well as all the muscles targeted? Preferably one that lists as much of the physiological data as possible. E.g. which stabilizers are activated, which secondary muscle is also activated, is it an extension or flexion. I am also looking for datasets which could help me with some of the physiological constraints, such as muscle recovery times, which muscles not to exercise together etc?
My goal is to algorithmically capture an OR model which I can provide with input data such as muscle group target and time and the model must output a schedule of exercises which targets all the muscles in that muscle group, is not physiologically harmful and is within the time constraint.

I don't have a specific data set or study in mind, but the US Army should have some data sets from recent studies.

Also, it should be fairly varied with categories ranging from 18 to 40 years old, various Heights, body fat content, sex, ethnicity, and race. Not to mention most soldiers are in good physical condition, healthy with proper nutrition and hydration.

As the holiday season comes into full gear and the year comes to an end, many people may be thinking about starting regular physical exercise as a new activity for the new year whether to keep fit or maintain ideal body weight. Throughout the years, there have been so many commercially well-known products from gym membership to home gadgets that people can do at home. Whether the gyms are used for exercises or for socializing, the lure to get new members to replace the members that quit is pretty much constant. Why do people quit the gym? As for home gadgets are concerned, they lure people with all kinds of gimmicks. They even make gadgets that require no actual conscious muscle contractions. The gadgets have electrodes to actually stimulate and contract the muscle fibers for you. People can buy a very expensive stationary bicycle and have a coach appear on a monitor screen cheering you on while exercising. Whether it's the gym or home gadgets to do exercises, most have failed and do not have much staying power. People eventually quit the gym for whatever reason, and the gadgets end up collecting dust or parts of a garage sale. Physical exercise to keep fit and to spend the extra calories consumed requires both work and commitment. One form of natural activity that people forget and underestimate that can still be used as an exercise to keep fit and healthy is "walking". The long lower limbs are perfectly made and have evolved to be used so we can be mobile and independent to move from one place to another and not only from the couch to a dining chair or inside the house to a driver's seat of a car.

1kg/ 8 times of Rep/ 30s/ 5 Sets/ 3m/ 3 sessions/week. Strengthening exercises
Kindly find out the loading prescription of non-dominate Biceps and the reason for choosing this loading ?
Relevant answer
Answer
It would be uncommon to prescribe a lower relative load to the weaker muscle. Why don't you do 1-RM testing on each arm and then prescribe the same training load (% 1RM) for each arm based on it's own 1-RM... the weaker arm will ultimately have a lower absolute load, but same relative load...
The National Strength and Conditioning Association uses the following RepMax table:
1 repetition max = 100% of 1RM
2 repetition max = 95% of 1RM
4 repetition max = 90% of 1RM
6 repetition max = 85% of 1RM
8 repetition max = 80% of 1RM
This would be a good starting point.... but remember that these are repetition max estimates and therefore training should be slightly below that for repeated sets. Also, it looks like you are just doing as many repetitions as possible during each 30 sec work bout, if I am reading it correctly. You may want to go on the lower end of the relative load, but 50-70% seems like a reasonable range. It depends on how many repetitions you want them to complete.... there is no prescribed load for your proposed protocol. Try it out on a few people and see where their repetition ranges fall and let that guide your decision!
Good luck!

In his book Black Swan, Taleb (2010) believes that the human mind is subject to many blind spots, illusions and biases and that: “The right strategy for inventors and entrepreneurs is to rely less on detailed plans and to focus as much as possible on creative thinking and recognizing opportunities when they arise. Excessive attention to what we know results in yet another similar weakness: we tend to learn the details instead of adopting general laws.” Resistance to change has long been cited as one of the key reasons why companies do not adapt to change on time. One of the approaches is exercise "How to destroy a company". Employees and stakeholders can be divided into groups to find the most effective ways to destroy a company. Lisa Bodell, founder and CEO of the company “Futurethink”, uses simple techniques to help organizations embrace change and increase their ability to innovate, such as Google, Novartis, and HBO: “The first time the HBO team performed this exercise, it created three tactics that a top competitor could use to destroy HBO. The American mining company regularly conducts this exercise in order to protect itself from both competitive and market forces.” Modern management has always existed for “best practices”. In trainings, managers use role models to encourage and direct change. New researches suggest a method better than the previous one. Scientists from the Kellogg School of Management in the USA conducted a series of experiments, and in one such experiment managers were gathered in small teams to create unusual creative purposes for a cardboard box. Before the brainstorming, half of the group was given the task to share the unpleasant stories from the past six months, and the other half was given the task to share the stories they are proud of. According to the results of the experiment, the teams that shared unpleasant stories generated 26 percent more ideas than the groups that shared proud stories.
