Hello. I'm trying to find out how to analyze the accelerometer-derived data in the NHANES 2011-2014 cycles (wrist-worn triaxial accelerometer). I want to transform the data to steps/day, but I'm not sure if there are equations to do it (e.g., from counts/minute to steps/minute), or do I need specialized software (e.g., Actilife)? I've read some articles analyzing the NHANES 2003-2006 cycles, but they used uniaxial accelerometers.
What article(s) would you suggest for me to understand how to proceed?

Subject: Invitation to participate in research about the inter-relationship between sleep pattern, physical activities and quality of life in students
Within an international scientific research framework approved by the Institutional Review Board of Qatar University (QU-IRB 1510-EA/21) led by the College of Education, we would like to invite you to answer the following online survey about The inter-relationship between sleep pattern, physical activities and quality of life in students.
We would like to kindly ask you to do your best to answer all questions, if possible, because this will allow us to anonymously process and analyze the data, and thus, improve the knowledge in the field.
The estimated time to complete the survey is of about 20 minutes and it is available in three languages:
In case of any query, please feel free to email the lead principal investigator Imen Moussa-Chamari:
Although objective measures, such as accelerometers or pedometers, are best for assessing physical activity among youth, these devices are designed to detect ambulatory movement and, therefore, may not detect static movements such as those commonly used during resistance training. I would like to know if there are any existing measures that could be used to supplement objective physical activity monitoring in order to capture participation in resistance-based exercise. I assume that it would be self-report but ideally I would like to use/adapt an instrument with acceptable psychometric properties (e.g., face validity, criterion validity, test-retest reliability etc).
Anyone have a SAS program to process data from the Recent Physical Activity Questionnaire (RPAQ)? The MRC lists a STATA syntax (https://www.mrc-epid.cam.ac.uk/physical-activity-downloads/), but I do not use STATA.
I'm using a software developed for smartphones to estimate the time spent in different physical activity intensities based on cut-points established for triaxial accelerometers. But even with previously developed studies that suggest a relative equivalence of "counts" measured by Smartphones and Actigraph accelerometers (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4414958/), I'm not sure if even with an equivalent sampling rate I can use cut-points for "counts" established for triaxial accelerometers. Can I do that, or are the "counts" estimated through the smartphone different from those estimated by actigraph accelerometers, even for an equal sampling rate?
I am interested in knowing if there is any research work exploring factors that may affect the way in which girls and boys (aged 9-12 yrs.) complete physical activity self-report measures (e.g., questionnaires). Do you know of any studies that indicate that girls record/adjust their subjective physical activity better (compared to device-measured physical activity) than boys?
Physical fitness is essential to allow people to carry out everyday activities. It is often particularly low in stroke survivors. It may limit their ability to perform everyday activities and also worsen any stroke-related disability. So, it is recommended that seniors do exercises in order to improve cognitive function, quality of life, and the ability to maintain physical activity. On the other hand, other researchers say that training programs increase the risk of having another stroke.
Should we wait for vaccine against COVID-19 or also look towards other possible options to reduce mortality rate of Corona virus. Can Physiotherapists critically analyze the effect of exercise in Corona patients as exercise has cardio-respiratory effects as well as influence on Immunity.
Need your help and suggestions please?
It is known that scientific knowledge is replicated each time at more unusual speeds, however, humanity expects more from our scientific work, that is, solutions to problems that have accumulated and that it is necessary to solve to improve the quality of life . It would be good to reflect on those expectations.
IPAQ or international physical activity questionnaire has separate part about leisure time activity.How to analyze this part to get value and can this questionnaire use to access the physical activity of postpartum mothers?
The effectiveness of gamified virtual reality for increasing adherence to exercise, affecting perceived exertion and improving mental and physical health: A preliminary study
Any feedback/suggestions would be greatly appreciated. I've also considered splitting this into multiple papers, however I feel that these variables are all interlinked.
Hello to the scientific community,
Between the global physical activity questionnaire (GPAQ) of the world health organization and the international physical activity questionnaire (IPAQ) which is the most suitable and best recommended questionnaire to assess the level of physical activity?
I read an article from Kathleen F. Janz, Elena M. Lutuchy, Phyllis Wenthe and Steven M. Levy called Measuring Activity in Children and Adolescents Using Self-Report: PAQ-C and PAQ-A.
They rescaled question 1 regarding this formula: Q1rescaled = 4(q1 - 1)/(1.7(max raw score) - 1) + 1. Does somebody any idea why? And could me somebody help to understand this formula?
It's unclear for me... Thanks. Marcela
I have recently incurred a radial nerve injury in my upper left arm, and am never of the mind that rest is what I need (lost time is lost time). Thus I have initiated some short term experiments while I have this injury, and am interested in learning what thoughts and experiences others have.
I am interested in martial arts and physical abilities, but not excluding other points of views.
I am trying to find validated cut-points for PA in adolescents using wrist-worn ActiGraph wGT3X+ accelerometers. For the young participants in my cohort I am using the cut points proposed by Chandler (Paediatric Obesity; 2016; 11) but these are only applicable to children aged 8-12 years. I have so far been unable to find accepted cut points for adolescents for wrist-worn devices.
What are the main factors associated with physical activity during middle or high school physical education?
Hello everybody! We are carrying out a research where we associate baseline to post-intervention changes between motivation and physical activity variables. My question is the following: In an experimental group, if I have a NEGATIVE association between INCREASES in introjected regulation and DECREASES in sedentary activity, how should I interpret it? Do you have any example of reference that describes this type of results between changes or similar? Many thanks in advance! Cheers.
There seems to be data on this for the last 5 decades, but I can not find any data for the period between the beginning of the Industrial Revolution in England (around 1760) and 1960.
To give you a breif summary of my work, I am mostly looking at the percentage time a participant spends in a certain play state when compared to the entire observationn duration. I was using parametric measures to analyse the data provided that all assumptions were met. However, I have recently come across CoDA (Compositional Data Analysis) and a recent study which shows significant differences between standard tests and CoDA tests. My question is whether it is neseccary to redo my data analysis or whether it would be ok to continue using standard testing meassures. Most instructions on CoDA also get a little bit too technical for me to understand. I have been struggling to really wrap my head around the differences betweeen the methods and how to accurately do CoDA. I am attaching the paper citation mentioned for your reference.

We are in the middle of a crisis, in the quarantines. Irresponsible behavior has brought us to our current state. We did not learn any lessons learned from viruses that preceded and resembled the COVID-19 virus. Today's topic is not the reason that led us to this situation but commenting on the measures we have taken. The study of (Bishwajit et al., 2017) examined the effects of physical activity on depression. Their study had a representative number of middle- and older-aged subjects (7204). They concluded that a lower frequency of vigorous physical activity was significantly associated with higher rates of depression diagnosed. Depression symptoms and physical inactivity are factors that are closely correlated with obesity (Garimella et al., 2016). The elderly population has a prevalence of anxiety and depression around 10 and 12 %, these findings are caused as a consequence of different factors. Health-related quality of life and physical function play an important role in depression and anxiety (Sousa et al., 2017). The logical conclusion is that physical activity can reduce the levels of depression. Many studies have addressed this topic. Throughout history, our race has evolved. From the beginning of the cognitive, through the agricultural and industrial revolution to the present, we can observe a trend of decline in physical activity. This trend was accompanied by the appearance of metabolic and chronic diseases. Chronic diseases are major killers in the modern era. Physical inactivity is the primary cause of most chronic diseases. (Booth et al., 2011). Physical activity primarily prevents, or delays, chronic diseases, implying that chronic disease need not be an inevitable outcome during life.
This brief introduction is just a small overview of the literature that has examined the topics of physical inactivity, depression, and chronic illnesses.
Because we are in quarantine, and our movement is restricted and in some environments disabled we face many difficulties. Speaking personally and listening to people from my surroundings, from a psychological point of view, quarantine has a rather negative impact on people. With this, the media and the internet, which is full of misinformation, make people panic.
The following questions are:
- Is quarantine an ethical solution?
- How will this inactivity affect people?
- How will inactivity affect obesity, chronic diseases, and ultimately, mortality?

One month data. According to WHO the recommended dose of physical activity (PA) is 8000 steps per day. Are these true levels of PA or a reflexion of job burnout? And how this PA is related to Heart Rate Variability (HRV)? Is it useful to set limits of PA?
Are they some strong Relationship between physical activity, emotional intelligence, self confidence and HAPPINNESS ?
I am trying to understand the difference between a structured and a semi-structured questionnaire with regard to the following sub-themes.
1. Is their freedom to add new questions to a semi-structured questionnaire OR is the freedom only to do with the wordings of the questions and the order in which they are to be asked?
2. If I am sending out an on-line questionnaire, Will it always be a structured questionnaire.
Would appreciate a discussion and any response will be valuable
I am looking for Finnish versions of the International Physical Activity Questionnaire - Long Form and Nordic MSK Questionnaire (Kourinka et al, 1987). Any help would be appreciated!
For a clinical study on post-operative physical activity, I would like to use a questionnaire to find out how active recruited patients are in general / have been before the surgery. I know about IPAQ (too long for our purpose) and its short form (not the best validity), but am not absolutely happy with either of them. Does anybody have a recommendation for a questionnaire that is short and sufficiently validated, or might at least be a good compromise?
Thank you all in advance!
A neat and smooth way of life, avoiding the acquisition of inadequate health habits, as well as certain foodstuffs, and the sensitivity which can be a cause of neurological disease, including MS, may also be cure for the disease
Such a macrobiotic diet, and low radioactive water (cca 6 Becquerel / Bq) lower temperatures (18-20° C), swimming pool and professionally indicated and controlled use of corticosteroids, symptomatic therapy and immunomodulatory drugs in different phases of the disease, proved to be very useful in many cases the form of RR MS, as evidenced by reports of many research papers, observations, the patients themselves and their medical practitioners.
Does anyone know the Metabolic Equivalents (METs) for the Youth Physical Activity Questionnaire (Y-PAQ)? I was able to find most, but not all, of the physical activities on website of the Compendium of Physical Activities.
However, a few activities (e.g., netball) are missing, and I wonder whether anyone has a list of the METs for each activity on Y-PAQ.
Firstly, is it correct to describe the study as an AB/BA crossover design if I have 2 conditions and 2 periods but all participants were followed-up at 16-months post-intervention also?
Secondly, are there any useful resources I can refer to, to figure out how to correctly analyse the data using SPSS?
Measurements were taken pre and post period 1 and then pre and post period 2 and again at 16-months post-intervention.
4 schools with 11 class groups were included. Before baseline 2 schools (6 class groups) were assigned to the AB condition and 2 schools (6 class groups) were assigned to the BA condition. A was a control condition where groups continued with normal PE lessons and B was the intervention condition (8-week intervention focusing on fundamental movement skill development). A 4-week washout period was included before groups crossed over for period 2. All participants were assessed for FMS proficiency and BMI across 5 time-points.
Time 1: Period 1 pre-test
Time 2: Period 1 post-test
4-week wash-out period, then groups crossed over for period 2
Time 3: Period 2 pre-test
Time 4: Period 2 post-test
Time 5: 16-month post-intervention
1. can an 8-week intervention programme lead to significant improvements in FMS proficiency levels?
2. can any improvement in FMS proficiency levels be maintained over time?
3. do the effects of the intervention programme vary by sex and/or weight status?
I've seen a lot of work talking about how chronic physical activity (PA) improves cognition, and that this is likely to come about due to changes in hormone and neurotransmitter levels (e.g. BDNF)
Im wondering what biological mechanisms are responsible for the benefits of acute PA?
we use the Global Physical Activity Questionnaire (GPAQ) quite a lot in our research but are still unsure how to cite it properly. Some studies use the WHO-website (1) as a reference, some others the publication of Armstrong&Bull (2).
Which one would you recommend?

I'm still struggling with this idea about active sitting.
Many of the big issues about movement have long been known. For example, in Kilbom's review in 1986 (cite below) she described in great length the many health disorders associated with the reduction in movement, such as associated with shifting from being a secretary in the 1970's to becoming a data entry operator. She very clearly explained the various impairments to heart disease, peripheral venous disorders, arthritis, and so on - and the reasons for our inability to feed the cells (especially in the spine) and eliminate waste products. So the information about the basis for active sitting has been there for quite a while. And certainly the newer research on ligaments over the last decade have a lot of implications.
But the question I have is how we can justify taking away the backrest and armrest in a primary chair. Active sitting makes sense to me as a second chair or for special situations such as populations with good core muscle control or specific disabilities or for certain tasks. But where is the evidence that active sitting even works? The majority of studies on sitting balls, for example, suggest there is little or no benefit. And Dr. Goossen's study in press in Ergonomics suggesting that movements actually reduce in the type of dynamic seating he looked at.
Dynamic seating and active seating are just garbage terms now that completely obscure the issues by lumping everything together, when the different types are quite different.

I am designing a physical activity framework for children with Cerebral Palsy attending special schools in South Africa. Most PA frameworks target children with CP classified from GMFCS I - III and GMFCS IV and V are generally neglected. Do you know studies that include IV and V? Please assist by sharing your thoughts and possible articles. Thanks
Many studies suggest that virtual reality rehabilitation can activate the cerebral cortex and improve the function of patients with neurological impairments. Also we hear hippo therapy has a positive effect on the physical function and psychological problems of children with Autism.
May hippo therapy and virtual reality together lead to overall improvements in the daily functioning and quality of life of these children?
I am currently an investigator in a CRT using gamification to reduce obesity. Part of the intervention is to provide schoolchildren and one family member with an activity tracker and reward those who exceed a threshold of steps with points.
For the pilot study, we purchased two activity trackers: Omron HJ-324U and Jawbone UP Move. The data cannot be extracted in bulk.
Do you have any guidance on which trackers allow bulk data extraction or how this can be done?
A lot of research in my field is conducted using Actigraph accelerometers and I would say 99% of the papers I've seen report "actigraph counts" as their outcome variable of interest. These counts are categorized into different intensities (e.g. moderate, vigorous physical activity)
However, I have a project where I'm collecting raw triaxial accelerometer data (from a smartphone in this case) and I would like to find an algorithm/cutpoints/thresholds that can convert raw triaxial acceleration to actigraph counts for the different intensities. Are there any papers that explain how this conversion is done?
I've seen a few papers discussing how to convert uniaxial acceleration to counts, but not sure how I would extend that to all 3 axes
the very routine method of learning of an skill or subject is physical practicing. such as reading, driving or just talking. but can it maybe possible to learn skills with just imagining them and being focus on them? if it is possible, a new learning method can be learn with just mind!
Media use and physical activity can have a positive or negative impact on health. Is there a model that theoretically justifies and describes the mechanisms of action?
I am interested in how the Baecke questionnaire can be used with adults who do not work.
The Questionnaire has a modified version for older adults
(Pereira MA, FitzGerald SJ, Gregg EW, Joswiak ML, Ryan WJ, Suminski RR, Utter AC, Zmuda JM. A collection of Physical Activity Questionnaires for health-related research. Med Sci Sports Exerc 1997 Jun;29(6 Suppl):S1-205)
But not one that may be adjusted for use with adults who do not work. Your views would be much appreciated.
In Poland we have a specified period of time in which we should conduct the research with IPAQ, mainly because of the weather conditions.
What is the situation in Spain and Italy? Are there also any period of time limitations to conduct study? I could not find any information...
Will be grateful for any help. As always...
All the best,
I am interested in using a physical activity tracker across a large population of children (aged 8-14), which would not only allow children to track their own activity and for researchers to implement behavior change techniques (goal setting etc), but also for researchers to collect the real-time data as well.
Does such technology exist or are current trackers reliant upon the participant to upload data to an app and then researchers access the data from a central point/hub?
Any guidance would be great
I look for other people who will participate in Conference HEPA 2017 in
I think that knowing each other before going there will be a great opportunity to
exchange our research topics and expieriences and together await this great
event. Furthermore, it could be a great occasion to consider future

What is your experience of using 6 MW Apps? Do you use step count based ones or GPS based? How do they relate to the formal ATS 6 minute hall walk test?
Many physicians and physiotherapists advise their patients who have knee osteoarthritis whether in earlier stage or late and chronic stage to stop stair climbing and use lifts if available.
Is this logic suitable for all types of patients with knee osteoarthritis?
Is there any evidence or published article that discuss this issue?
What type of Accelerometers should I use? What are the things should I consider?
what is the best mental test to assess the effect of dietary supplements on central fatigue after high intensity exercise?
We are comparing caloric expenditure using METs to determine distances covered between different exercises.
Eg: what is the bicycling equivalent of walking in miles
I am working on a project to assess the physical activity levels of adult population. I would like to know which questionnaire is better to use: IPAQ or GPAQ?
I'm looking for any information about phisical activity (which type of sport or PA) and the procedure to test the physical capacity (aerobic, anaerobic, strenght, balance, flexibility, etc...) in this group.
Our team already follow different typology of cognitive disability (Down Syndrome and so on), but we never follow autistic person.
In order to start any project I'm asking for previous experience or study about PA (physical activity), sports and testing in this syndrome..
Nowadays, it is not possible to directly examine the structural changes at the brain cell level (e.g., neurogenesis). Thus, it is still unclear the actual effects of physical exercise on brain derived neurotrophic factors release (BDNF). However, the scientific technological progress has allowed to indirectly study the brain structures and changes at a more macroscopic level.
In order to study the relationship between exercise and BDNF changes in children/adolescent population, what are the main feasible, non-invasive methods?
LIDO WorkSet is used in Human Factors lab to evaluate the work capacity of individuals engaged in various physical activities; for e.g. to assess isometric strength measurement (isometric grip strength, torsional strength etc.) and the level of effort required for specific work tasks.
I wanted to do a longitudinal survey over (3 time points) to measure fatigue levels and some correlates on a group of patients.
I know our patient numbers based on the database. When I did an estimate of eligible patients based on diagnosis and age, we have 194 eligible patients.
From similar studies, 80% of patients are eligible for the study and an estimated 40% attrition rate during the longitudinal measures. We are not aiming to power any specific endpoints as there are still a lot of unknown wit regards to the thing we are measuring. Based on this my questions are:
1. Are the information presented enough to estimate the sample size I need?
2. If so, can you signpost or enlighten me on how to best estimate the needed sample size?
How can I record the central relative timing of the components of the dart throwing?
We are going to analysis the EEG signal of dart throwing to components of throwing so that measuring the central relative timing and investigating the validation of the stability of the relative timing of GMP (about the schema theory, Schmidt, 1975, 2003).
We are validating a cognitive reserve measure (in eldery over 65) and want to include a measure of physical activity throughout life. We'd need a paper-and-pencil, self-administrative measure. Is there a possible recommendation/consensus in the field? Lykert type scale would be most suitable, but calculating a measure based on active hrs per week or similar, is also fine.
I would like to buy portable, hand-held urine analyer - especially to have good values of urine osmolality, gravity (hydration status) of the sport athletes
Any recommendation or advice? Some good analyzrs which are enable to publish in peer- reviewed journals
