Questions related to Exercise Physiology
There are many biomarkers such as TNf-Alpha, CRP, and IL-1, but I'm looking for some novel biomarkers to measure.
I am looking for a practical model to simulate physiology or any other function related to sport science, especially exercise physiology.
Most UG programs have both and Exercise Testing and Prescription course and Exercise Physiology course, each with lab components or their own separate labs. Most of the time I see repeat concepts/tests/assessments taught in these labs. How do we separate them out so students don't see repeat items?
The Journal of Exercise & Organ Cross Talk (JEOCT) publishes original research articles and reviews describing relevant new observations on molecular, biochemical and cellular mechanisms involved in human physiology after exercise training. All areas of the cellular & molecular exercise physiology are covered. In other word, the journal focus on mechanisms through which exercise can prevent or treat chronic-degenerative disease, contributing to prevention and personalized treatment of specific diseases and health maintenance with a translational perspective.
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)?
Has anyone seen any interesting gaps in the literature related to cardiovascular exercise physiology and could suggest any potential topic? Would be greatly appreciated
If there is a small amount of primary and systematic resources in a particular area of exercise physiology, can evidence gap mapping(EGM) paper be written about it? In that case, will citation to articles in Google Scholar be valid? in which journal could we published EGM written in the field of exercise physiology and health?
As a exercise physiology student in Australia, is necessary to accredit in ACSM? I'm not sure where I want to work in the future, maybe China or Europe. Can anyone give suggestions about if I want to work in other countries, which organization has high value for me to accredit to develop my career?
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.
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)
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.
Their is need to understand the safety and efficacy of exercise therapy on cancer treatment–induced cardiovascular toxicity and tumor progression and metastasis in oncology practice, this can be achieved by having a fundamental knowledge of exercise prescription, dosing and personalization with regards to cancer treatment and according to global best practices.
May linear regression show that an method/methods is/are valid even though this method(s) is not valid according to bland-altmand and paired sample t test.
Do you know any intervention program that performs aerobic exercise with teachers to improve their wellbeing or similar variables related to your health (stress, anxiety, burnout, depresion?
There are numerous intervention programs that use techniques like yoga or mindfulness but I have not found one that is based on aerobic exercise.
I am conducting research on the subject and I would like to document myself. Thank you.
Hormesis is a concept to explain of adaptation of body to certain dose of Toxic substance. if some condition in exercise like of produce of Free radical, reactive oxygen species, decrease of pH and etc be a toxic condition for body can we called exercise for one of factor of hormesis? what is your idea?
can someone explain about of effect of this both training model on muscle activation and muscle damage? moreover what effect they have on the muscle hypertrophy?
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?
Does anyone have experience measuring irisin, kynurenine and or BDNF concentrations with human blood samples? If so, can you recommend best assay kits?
I want to measure electrolytes in sweat during training, and for the analysis we need something like 100 microliters of sweat collected in an eppendorf or probe. Thank you.
We will start culturing HASMCs and HAECs soon in our lab and I am trying to get ready. However, I am confused regarding what type of medium to use. I have done a literature scan and it seems a variety of different media are in use by different researchers. Do you have any experience? What do you use to keep these cells happy?
What I have learned from what I read:
1. HASMCs--> DMEM low glucose (or DMEM/F12 3:1 ratio) + 10% FBS + ascorbic acid + nonessential aminoacids + pen/strep
-DMEM or DMEM/F12?
-What quality of FBS do you use? US origin?
2. HAECs--> Medium 199 (life technologies) + 10% FBS (life technologies) + pen/strep
-What difference would it make to have HEPES in Medium 199?
3. Trypsin (which concentration? and with or without EDTA?)
4. Use DPBS (instead of PBS which has Ca in it)
And also in some papers it is suggested to use collagen or gelatin coated plates to seed these cells on. What is your experience?
Sorry, I asked quite a bit of questions! Thanks very much for your time!
I would like to know if prolongued and accumulated fatigue is related to changes (decrements) in muscle stiffness (loss of muscle tone). If possible, I need some references regarding the physiology behind this phenomena.
like when exercising abs, do the abs muscles use the abdominal fat first? It is so popular but can't find an evidence.
If glucagon/epinephrine circulate in the blood stream, then it can possibly stimulate lipolysis in any area of adipose tissues, and the free fatty acids travel through the blood stream too.
any thoughts please??
The effect of an acute exercise stimulus would last about 48 hours. If we perform cell cultures (lasting more than 48 hours) and then measure a protein or RNA, would that measurement really reflect the effect of acute exercise?
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.
Did you notice that when you test your athletes on the treadmill (during season few times) they try to remember previous result ( time or speed of treadmill when they stopped)??
What my point is that when I want to re - test and examine if their time - to exhaustion increased - my athletes have motivation to continue running until they beat their previous results but this is strictly mental/psycho ability(not because of training effects or acute supplementation e.g. some pre - workout).
Should I cover the treadmill screen to not show them what speed and time of exercise they reached and then re - test them after training period?
For ectothermic animals, is the energy supply of the heart likely to be different from the activity state (during hibernation or sprinting) or food supply (during fasting), switching between anaerobic metabolic and aerobic metabolism?
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.
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.
If Carbohydrates are more effcient in regards ATP production per oxygen consumption why one of the main endurance adaptation is that athletes rely more on fat metabolism???
I am interested in the response of Keap1-Nrf2 signaling to exercise and if there are any post translational modifications occurring in this signaling pathway. Direction to primary research literature would be helpful. Thanks in advance!
Should I focus on the amount of muscle mass or muscle function in the sarcopenic elderly?
12 week exercise intervention using power training (20-50% 1RM) or whole body vibration. Complete 3x10 of 4 lower body exercises with 1-3 minutes rest.
Serum collection is early in the morning while fasted using red top vacutainers.
Participants will continue with regular physician care and any prescribed therapy.
All participants are >65 years and long-term care residents.
The presence of comorbidity is common among participants. Diseases range from T2DM, dementia, stroke, hypertension, Alzheimer disease, GERD, and osteoporosis.
Some participants are taking statins.
The aerobic treadmill exercise is feasible, safe and it may improve early anomalies of posture and gait in early MS patients. In the context of an impairment oriented rehabilitation approach, the set of instrumental measurements proposed seems to be able to identify subclinical anomalies in a very low degree of functional involvement on an individual basis.

What could be possible disadvantages of choosing one or the other?
Assuming the person has had it for six years, went from 190 pounds to 144 due to the inability to eat more than 1500 calories in a day comfortably. Tried western medicine route, eradicated H pylori and symptoms only got worse. Height is 6'2. He never has any energy. After every meal he feels weighed down for hours. Pain in legs, knees, and arms. Tongue is pale with a little white coating, not as much as to indicate thrush. Pulse is long and slow, about 70 or a few less beats per minute. Blood pressure is a little low, about 100/60. 28 years old. Symptoms are dull epigastric pain. Endoscopy showed inflammation but no ulcer.
I am looking to purchase a reliable heart rate monitor for research use. Despite the obvious quality of Polar HR equipment (I used Polar team in my previous institution), the majority of the new monitors appear only to have software for use on a mobile phone (e.g. Polar H7). I am concerned about the limitation of this software to allow detailed analysis of the data collected.
I would be keen to hear opinions on good (i.e. valid, reliable) heart rate monitors that connect to software that allows detailed analysis of a session (i.e. mean HR, peak HR, analysis of HR within different time periods).
I have already had a trawl around Research Gate and seen some interesting information, but these mainly relate to HR monitors for specific HRV measurements. I would be using the device to record HR during short and long duration exercise tests (i.e. max tests, performance tests).
I am trying to determine which portable lactate monitor is the best to use for research. Since it will be used in exercise testing, it needs to be accurate and reliable at both low (<5 mmol/L) and high (>10 mmol/L) concentrations.
There are many on the market with several papers detailing supposed reliability so it is not the most straight forward decision.
Any information or recommendations would be greatly appreciated.
I wonder if there could be an association with partaking in regular HIIT and development of enduring fatigue in adults (especially those with a sedentary occupations in the absence of other health conditions)? I would be interested to hear about:
- Clinical Observations?
- Anecdotal Accounts?
Does anyone know where to buy a translated to english copy of Zur Interpretation von Laktatleistungskurven - experimentelle Ergebnisse mit computergestuetzten Nachberechnungen which translates to For the interpretation of lactate power curves - experimental results with computergestuetzten recalculations
Hello! We are doing our thesis which is to measure muscle activity with lbp cyclers and compare the activity with no pain cyclers. It's a bit challenging for us since we are going to measure the activity while the cycler is riding in trails (Mountain biking). Does anyone have any suggetions / ideas how we could reduce the loss and the interference which are caused while cycling? Is it best that the cycler would use no shirt or which kind of results would we get if the electroids are place under shirt? We are using Biomonitor ME6000 to measure and we are using Ambu Blue sensors ( size m)
Could cerebral hipercapnia with normoxia serve as the trigger for epileptic seizure in maximal voluntary breath hold in epileptic freedivers? If not, are you aware of any known physiological associates that would increase risk of getting epileptic attack during static and dynamic breath hold? Due to diving reflex there is hipercapnia with hypoxia present in the entire body except brain where there is hypercapnia with normoxia.
Is it possible for human beings to have low total testosterone levels (below 300 ng/dl) yet normal or high levels of free or biologically active testosterone? Or even vice versa? I am talking about measured levels, not calculated levels. Thank you.
How long should the high intensity interval be to provide sufficient stimulus for adaptation (30 seconds)? And how long should the rest be in between intervals (3-5minutes)? Active rest or complete sedentary rest period? What should the resistance be? What frequency should the exercise protocol be applied (3x per week)? Would this type of exercise be reasonable in an aging population?
Most of the longitudinal studies on the cardiac adaptation to exercise training seems to report on wall thickening and moderate increase in internal ventricular diameter at best, with some notable exceptions, e.g.:
Any observations and considerations how to effectively induce "physiological" ventricular chamber expansion are welcomed. Also are speculations/hypotheses on the means to induce longitudinal (apex to valves) left ventricular enlargement.
Any articles regarding transcriptional regulation of skeletal muscle and associated proteins (MCT1,4, GLUT1) also any articles or papers form the early 1900's including Otto Fritz Meyerhof and associated colleagues.
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.

There is an endless list of studies on effect on physical exercise on metabolic disorders like NAFLD. Most have used self reported questionnaires especially in retrospective studies which have an inherent recall bias. What should be used for a prospective study in this field? Pedometers or accelerometers or any other instrument?
Perhaps normalizing COP data would provide a more logical way of interpreting COP excursions below feet of different dimensions? Thank you for any input.
Should it be totally random or a transition part bending from deep layer to superficial layer? Is it continuous from the deep layer? Thanks!
Can anybody help me to understand internal and external generation of movements. Is internal means conscious or voluntary? or is external means is a reflex?
This question relates to the theme of my research project. We will test three conditions (AX-CPT, motor imagery and control task), and then perform a type of exercise time trials on Wattbike.
This equation was developed by Stickland et al. (2003) in his study "Prediction of Maximal Aerobic Power From the 20-m Multi-Stage Shuttle Run Test".
Does anyone know of studies/research that has critiqued the methods of VT and LT measurement and its validity in invasion sports athletes
How much water are we able to absorb in given amount of time in rest or during exercise? I have came across different values and can't really figure out what is to be advised to ultra endurance athletes performing in the heat, as accumulation of unabsorbed fluid can cause gastrointestinal problems ...
The literature shows that myocardial antioxidant capacity, cardiac Heat Shock Porteins, Nitric Oxide, ATP-dependent potassium channel function, and opioid system activation are related to this, but also turns it inconclusive in some original articles or systematic reviews.
