Questions related to Sports Medicine
As many studies identified of genetic variants linked to training responses and sport-related traits, we could hypothesize that the R allele was more common in sprint and power athletes and the X allele more common in endurance athletes. Other said, the Middle/Long distance runner (X allele) was would have less response to strength training and Sprinter (R allele) would have less response to endurance training. However, in fact Sprinter would need endurance training to improve aerobic capacity and specific endurance and MD/LD need strength training as well.
Due to the fact, that there are huge amounts of drops outs in athletes career for talented youth Sprinter/MD/LD runners, therefore have a couple of questions :
1. Is any biomarkers we could use to get proper limit of load (Intensity, reps, and recovery) for Sprinter (R allele) while doing endurance exercise or for MD/LD runners (X allele) while performing strength/speed training, so they can keep their genetic potential ?
2. How we could know the proper limit of load/intensity for strength, speed training for MD/LD runners or endurance training for sprinters ?
3. Is the quality of R allele (i.g. speed of muscle contraction) or X (i.g. O2 consumption) allele will reduce due to mismatched training ?
Thank in advance.
Expanded Disability Status Scale (EDSS) is a method of quantifying disability in multiple sclerosis that is the most widely used measurement tool to describe disease progression in patients with MS.
What types of exercise and training variables (volume, intensity, repetitions, frequency, exercise selection, exercise order, and rest) are recommended for patients with Multiple sclerosis (MS)?
Chemicals added to swimming pools leach into the air above the surface of the water, with the result that regular lap swimmers must be inhaling them to a significantly greater degree than casual pool users. Have there been any studies on the long term health effects?
I am looking for minimum dose of Nitrate that should be consumed to produce vasodilatation. I Have looked several papers on this issue and there were ones which gave different doses of Nitrate to produce vasodilatation. However, none of them or any other paper reported the ''minimum dose'' of Nitrate to achieve vasodilation.
pre-registration is a key element in open science practice. There are several options on the market for pre-registering an intended research project. I wonder if there is a tendency towards a specific pre-registration platform for exercise science research. For sports psychology it seems to be OSF, but I could not identify a preference for exercise science studies.
What do you think is the most used pre-registration platform for exercise science research and/or which one would you recommend for this field of science?
Currently working on literature regarding the effects of cooling on MS patients.
Effects on physical performances, balance, cognitive impairments and patients' comfort.
I've already read the Meyer-Heim article ublished on 2007(Multiple Sclerosis, 2007; 13: 232-237), and Nilsagard's article (Disability and Rehabilitation: Assistive Technology, September 2006; 1(4): 225 – 233).
I'm actually trying to find alternate references that could i) increase my understanding in physiological rationales of those enhancement; ii) lead my team research on a "ideal" cooling intervention (avoiding thermal discomfort while getting improvement)
The IPAQ scoring protocol defines the low, moderate and high categories of physical activity but does not clearly state how these were derived (not the actual cut-offs but the basis for the three categories). I noticed that the The American College of Sports Medicine and American Heart Association recommendations for minimal physical activity correspond to the moderate category of IPAQ-SF. But is there any reference that specifically states this?
Many protein shake powder mixes contain digestive enzymes such as protease, lipase, and cellulase. However, the products do not detail from which organism the proteins are produced or which protein homolog is used. I would imagine that the enzymes are produced in yeast or fungi. I am am curious regarding which organisms are used. Also, is the native form of the protein harvested from these organisms, or are they made to produce a recombinant human version? In the case of cellulase, there is no human homolog, so it must be from another organism. Regardless, should not the host species be listed on the product? Additionally, if the protein is not naturally occurring in humans, is it ever a good idea to consume it in high quantities?
Hello everyone. I was asked to submit our original research (pilot study) to Sports and Exercise Medicine Open Access Journal (SEMOJ)...we are in the process of rewrites and I was ask if the $1000 publication fee is the normal for the industry. I know that when we submitted to the Orthopedic Journal of Sports Medicine (OJSM) they also charged a similar fee. I was wandering if The Sports and Exercise Medicine Open Access Journal is legitimate? I don't mind paying the fee if it gets my work out there to the scientific community. Thanks.
The paper, "Rugby athletes and the prevention of injuries: asn asnalysis on judgement skills and decisions-made" European Journal of Sports Medicine. March 2016 by Broughton, H; Cromie, S;Trimble, T;Cummiskey, J; and Corri, D. highlighted the potential in rugby union that injuries can minimise injury eg at the scrum and tackle
I am interested in doing a comparative study between the common football injuries in Sudan and England. I would appreciate any information on the injuries in Sudan, treatment methods and training practices.
heat acclimatization can increase performance of athlete and occupational for physical activity in heat condition.
for this purpose we have to train for adaptation in heat condition regularly. but I have some question about chronic heat stress.
does living in heat climate can lead to chronic fatigue?
does hyperthermia and heat illness occur without any symptom chronically?
Genetics, stem cells research, artificial intelligence, nanotechnology, tissue engineering, sports medicine, mechanical devices, etc. may contribute to achieve functional immortality.
I was wondering about the morality of taking performance enhancing substances, during the time of sporting competitions, even if it helps a medical condition.
I read a meta-analysis, and he wrote: “For resistance training, we coded for frequency, mean training intensity, volume (sets of strength training), and type of training split used. Intensity for resistance was coded as the average percent of 1 repetition maximum (1RM) used .” How to deal with this situation when the program just like the picture?
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?
Patient is K3 and enjoys hiking and working out. His goals are that he would like to be able to squat at the gym and have greater stability on uneven ground when hiking. When he tries to squat his prosthetic foot lifts up and he would like it to stay level with the floor.
Exercises on unstable surface are very useful on the rehabilitation of prorpioceptive impairments, but i want to know if we can concentrate the work on a specific part of the lower limb
I'm looking for experts in the topical absorption of menthol, particularly as it relates to topical analgesics. In particular, I would like to know if there is data on specific percentages of menthol absorbed through the skin and pharmacological action based on that percentage.
I am looking at creating my own model using Visual3D, however I made the rookie mistake of not saving a copy of my labelled and gap-filled data without the model applied to the trials. If anyone knows a way to remove the model from the trial without going through having to re-label etc I would be forever grateful.

Hello! I was reading a Thermal Cycler User Manual and I found a function (extend) that allows progressive lengthening or shortening of
a temperature step hold each time a step is executed in a cycle. It said that it was usefull for accommodating an enzyme with diminishing activity. I have never heard this term. Can anyone tell me about this kind of enzymes.
What are the reasons of knee cracking in young people who do not suffer from any symptoms? In particular, cracking that comes with normal activities.
Is this normal for such type of knee cracking? Should we treat this issue?
Any suggested article that explain this issue would be appreciated!
Field of my interest is systemic physiological response to maximal cycling and running incremental test, comparison this results and practical application for functional diagnostic.
If the number of reps changes through training sesions does the RPE too? Or is RPE kept between 8-9. What i mean is: i understand DUP programming; but a hypertophy set can be as high in RPE as a strenght one; that is why i'm asking.
Last question: wouldn't it be also interesting comparing RPE based training to % training; but instead of the classical approach using an encoder/accelerometer? (to have precise 1RM daily data)
thanks in advance
I was wondering whether anyone could steer me in the direction of research that assessed changes in muscle activation during squats as the external load increases.
For example, some individuals' technique unintentionally changes when external load surpasses >85% 1RM, resulting in a greater increase in hip-extensor activation in relation to knee-extensor activation.
is it beneficial to train taller athletes (as in basketball) for better balance and stability? Maybe using neuromuscular training? Do athletes with longer limbs exhibit poorer balance and limb control? Maybe this could contribute to increased injury risk? Also, what are the implications of training (weight training) the taller athlete and what measures must be taken to ensure safe and effective exercise? Does anyone have any references that might answer some of these questions?
does anyone have experience/references regarding exercise prescription/physical characteristics/ injury rate of long limbed athletes (basketball players in particular but not limited too)? I'm interested in evidence of reduced balance, stability, core strength, body control, proprioception etc...
I am looking for un-published, grey (theses, conference papers) and in-press data comparing ratings of perceived exertion (RPE) to one of the following criterion measures, during resistance exercise (dynamic, eccentric and Isometric included): Workload, Heart Rate, Blood pressure, Blood lactate or EMG.
This data is required for a meta-analysis looking at the validity of RPE as a measure of resistance exercise intensity.
You do not need to have completed statistical analysis comparing or correlated RPE to the criterion measure; If you have collected data for RPE and one of the criterion measures, I will just need sample sizes, means and SD's for each group/variable.
If you would be willing to share this data with me please let me know.
I'm looking to see whether there has been a ramp test of this sort of protocol published in the literature, so I may find it and post a reference below, but if anyone knows of a paper where it is used then please let me know!
Looking for a measure of indirect calorimetry, such as a metabolic cart (like would be used during a cardiac stress test) or metabolic hood.
I’m currently investigating changes of miRNAs expression due to an exercise intervention. I analyzed a total number of 187 different miRNAs. Now I have a problem with non detected samples and their statistical evaluation. Some of the selected miRNAs showed signals only in a smaller number of samples (patients) (e.g. 35 instead of 40). Some samples showed signals only at one time point but not in the other and therefore fold change calculations are not possible.
What would be the better option for such samples, to use only the detectable values for statistics or filling in anything for the missing values?
I would be very pleased if someone can give me suggestions, how to cope with this problem.
Looking for an article or a study that focuses on, or includes the effects of eccentric resistance training on flexibility.
Various techniques for measurement of body composition are commonly used in human performance laboratories. Some that are often seen are skinfold thickness measurements, BMI, bioelectrical impedance, DEXA, bod-pod etc.
What would be the best method/combination of methods for measuring body composition in athletes? Should there be a difference in methods used for high-intensity sports and low to moderate intensity sports and healthy non athletes?
What do you use in your lab and could you suggest some review on that topic or provide possible guidelines for that issue.
Thank you in advance,
Here is a second topic that I am researching. If anyone has any opinions and/or research they think could be beneficial to me in answering this research question, please do add it in an answer.
Thanks in advance,
Is there investigations about the role of leg stiffness, and maybe also muscle flexibility (moreover quadriceps, amstrings and triceps surae) , on running economy or other parameters in (endurance) running (performance, injury risk,...) ?
Eccentric training adaptations include changes in muscle architecture. Are there any studies which showed different adaptations in men vs women?
Amount of daylight exposure is known to be a predictor for work-related stress and job satisfaction. However daylight exposure is not the same as 'time spending outside'. I am curious if there are studies around who investigated the relationship between time spending outside and e.g. stress, fatigue, mental health, etc.
Or, what is the most suitable definition of 'time spending outside'?
I'm mostly interested in whether X-ray or MRI was used, whether operated or contralateral knee was measured and which parameters were considered.
If somebody was to train at a high level of intensity for a shorter time and then somebody else was to go hiking, but for longer what would be an accurate formula to judge both these levels of activity?
I would like to measure the impact of an initial physiotherapy assessment (oriented on prevention) on the percentage of desertion in gyms.
Thanks in advance.
Recently, we had a case of 21yo woman with severe hallux valgus and flatfoot. We tried Lapidus procedure (TMT I arthrodesis and lateral release WITHOUT intermetatarsal stabilisation) and subcapital chevron derotational osteotomy for DMAA correction. Due to traction of the EHL effect was stil unsatisfactory. We decided to add the Akin procedure in the proximal phalanx as a "last hope" procedure. Cosmetic effect seems good. Do you have any experience with this method or do you do try anything different in such cases?
With all the relatively recent developments in recovery protocol for athletes (post game stretching, active recovery, contrast therapy, cold water immersion, compression garments, massage etc.) have there been any studies that utilize qualitative methods such as an interview, cross sectional group discussions between sports.
An approach that may provide rich data to be interpreted using perhaps an intervention involving the sports science team and coaching staff, potentially leading to a more scientifically sound approach that is not merely using practices because they are beneficial but because they are beneficial for specific athletes, sports, circumstances-heavy session, rehabilitation session etc.
I'm diving into tendinopathy research and started to wonder what nonsurgically repaired tendon looks like? Does it look normal? Is supposed to look tendinopathic. With the rise of regenerative techniques, it seems like much of the treatments are focused on causing a localized tissue response, bringing in exogenous growth factors, or eliminating vascular areas of the tendon.
Assuming these techniques work, what does a successful repaired tendon look like?
I hope that everybody knows about the curling sport. The literature search reveals there is an evidence that the curlers had severe knee pain in his/her sliding leg (deep flexed knee).
However, I could not found any information about what is the cause of that pain? where is the pain come from (for instance, from muscle or soft tissue overload) or where is the location? (anterior or posterolateral).
please advise to me, share your knowledge, and please refer related publication including unpublished study, useful websites, and injury survey.
I would like to know whether Increasing attentional demand by implementing a cognitive task concomitant with a unstable balance condition should have a greater influence on postural control, comparing two different groups non-athletes and athletes, both young male, 20 – 30 years old.
I need a free software to simulate athletic movements, for example parallel movements in gymnastics. I will be appreciate that someone help me about this matter.
Several studies suggest that when subjects mentally rehearse or execute a familiar action, they engage similar neural and cognitive operations. However, some situations, among which the muscular fatigue can interfer directly in these mentally organization. In fact, there are, mainly physiological disorders that can also modifying the movement standard. I would like to receive recently papers which deal with this subject.
Looking for details on measurement criteria, equipment and typical frequencies used.
Gut hormones could be used to meassure exercise induced anorexia, and grelin has some effect increasing hungry levels and energy intake, but there are many kinds of ghrelin (acilated ghrelin, non acylated ghrelin,total ghrelin, active ghrelin)
I want to look at various methods of monitoring fatigue of the somatic nervous system and how it relates to athletic performance and injury risk.
