Questions related to Sport Nutrition
Used to work with NutWin Software (UNIFESP, Sao Paulo, Brazil) like nutritonal software, it seems to have an installation problem (not solved).
For this reason I am looking for other differents nutrition softwares. Relatively easy to work and follow subjects and bibliography validation if could be possible.
Thank you in advance
Heart Rate Variability is a well known and useful concept in Biomedical Engineering and Medical Sciences. Breath Rate is a lesser researched field and a newer measure Breath-Rate Variability is introduced recently to quantify meditation effect.
It is gaining attention of researchers as BRV has a number of novel applications. What could they be.
Recently, I was in a workshop concerning sports nutrition, the person delivering the information stated that there is no proof that detox diet exists and is effective, her statement blew my mind, as she claimed that a body is able to detoxify its self naturally!, I was definitely against her statement, because if it was true then why there is a huge amount of cancer diagnosed patients, due to the chemicals or wrong diets or many other causes related to foods and medication, many studies have shown that customized detox diet plans are really effective, and in my clinic personally I have followed customized detox diet plans and the blood tests showed amazing improvements on all aspects, I need the aid in my statement and thoughts against her, any study, medical proof or so would be so helpful.
Hi All -
I am posting this as I am currently completing research for an MSc in Sports Nutrition.
The topic I am is nutrition and hydration practices in golfers - and I am aiming to recruit as many participants as possible. This is being done via a short questionnaire.
I am hoping posting a link here can gain some useful responses to the study.
Any responses would be greatly appreciated
Can we eliminate BCAAs supplement from our daily nutrition plan? Please read the following article and subsequently participate in this discussion.
Gut microbes ferment carbohydrates and produce SCFA among other products. They can also feed on bile acids.
Are they also able to use fatty acids and triglycerides as sources of energy?
Thank you to the expert scientists that can help this uneducated PhD who is too busy to dive into literature at the moment.
We would like to measure the influence of the use of social media on lifestyle (e.g. sport, nutrition, consumer behaviour). Do you know of similar research and approaches?
Food matrix refer to other components in the food that could synergic effect with macronutrient or micronutrient in food. One review had shown that whole milk had more effect than low fat milk or iso-milk protein for muscle protein synthesis regardless of reach to leucine threshold after exercise. This effect was without reaching to leucine threshold, due to exist of food matrix in whole milk. So I would like to plan this discuss about coffee component. The one of component in coffee that very application in exercise is caffeine and many research discussed about of different dose of caffeine for effectiveness during exercise. But many researches used the caffeine individually and in form of supplement (for example: pills, gum, and etc). Now I want to express this issue, does all of coffee component with together had more synergic effect than individually form of each component? Does synergic effect of coffee component more important than quantities of each components in individually form? For example maybe food matrix of coffee for effectiveness of caffeine more important than dose of caffeine? What’s your idea about food matrix for exercise performance?
The effects of acute exercise on plasma glutamine concentration appear to be largely dependent on the duration and intensity of exercise. Many studies showed that when there is a deficiency of glutamine or when the amount of glutamine is reduced during increased stress or exercise, the body experiences a suppression of the immune system until glutamine levels are restored through either diet or supplements. So I need your experience about the efficacy of L-glutamine supplement on sport training and athletes?
some athletes follow the paleolithic diet. paleolithic diet also known as caveman diet. in this diet you have to eat like of a caveman. what is your idea about this diet? can this diet increase the athletic performance? can anyone explain about the aspect of health of this diet?
I'm a pro-triathlete and researcher and very interested in the use of Maurten. Can you share any current findings on this project? I'm currently writing a report on sports nutrition for race day for the IOC and I'm very interested in what has been found for the use of Maurten sports drink and gel so far.
Hope to hear from you.
with kind regards,

Nitrogen oxide (NO) and creatine interact in skeletal muscle cells. So is supplement of creatine and NO helpfull?
Is sport science about individual holistic approach, or inter-individual reductionistic specialism?
Should someone try to know as much as possible about everything related to the wide field of sport science (nutrition, mechanics, chemics, psychology, genes, pathways, etc. etc.)
Or should someone be a specialist in one or more fields and look for inter-individual coöperation?
Or both (but is this possible?)
we know that insulin strike by high glycemic index food Block the cAMP signaling but some personal trainer said we need to insulin secrition for recovery of muscle after exercise. in the other hand if our purpose is increase of fat oxidation we shoud intake low glycemic index.
so I want to understand that how much insulin help to recovery of muscle?
which one of glycemic index better for fat oxidation and recovery after exersice?
Based on the ABCD Classification system, BCAAs are classified as a ‘Group C’ supplement. This means that they don’t work, but some studies reported that sports performance and muscle mass can be enhanced by BCAA supplementation. In addition, data showed that BCAA supplementation before and after exercise had beneficial effects for decreasing exercise-induced muscle damage and promoting muscle-protein synthesis.
It is claimed in some articles (2014/16) that big muscles can have 40 g protein and smaller one 20 g protein in their recovery. Opinions?
So glutes, latissimus dorsi, pectoralis major should have 40 g?
So what about biceps and triceps? Is it not depending on how intensive these are trained?
What about chest-triceps, and back-biceps training what is recommended in those cases?
This also in light of recent debates about what are big or small muscles?
I and one of my colleagues are currently working on a systematic review and meta-analysis of the effect of chocolate milk compared to other sports beverages on the markers of recovery from exercise. It is registered in PROSPERO: http://www.crd.york.ac.uk/PROSPERO/display_record.asp?ID=CRD42016038090. Although my field of study is nutrition, however, I believe the resulting manuscript should be reviewed by an expert in the field. We are looking for cooperation with an expert in the field of sports nutrition with some experience in systematic reviews and meta-analyses to critically review the manuscript (the way we analyzed and represented the data) and also to check for its possible writing errors. Please contact me if you are interested and have time to put on this work.
Excluding any evidence relating to sports nutrition - this question is around the clinical evidence base for using oral nutritional supplements or enteral nutrition with added leucine, in patients with chronic conditions and particularly head and neck cancer. Thanks in advance!
For my university project (sports nutrition), I have to re-create a specific sports supplement (specifically for the sport of bodybuilding or, people who go to the gym and workout) and explain what ingredients I have chosen and why they have been chosen for?
I have tried researching for journal articles that talk about protein and whey for the use of bodybuilding but have not found anything that goes into depth in regards to the ingredients that are used for the creation of whey protein.
what is the best mental test to assess the effect of dietary supplements on central fatigue after high intensity exercise?
Good afternoon, I'm going to start a project for assessing the welfare and fitness among an airport military staff. In addition to the physical tests that we perform annually on over a thousand people, I would also like to explore other aspects in their life, such as the level of motor activity, sport, nutrition and employment. Would someone help me to choose the best and valid questionnaires that we can use for that? For the level of physical activity I'm using HAPQ. For the rest!?
I am currently writing my dissertation, although the question i have asked is on building the mind muscle connection, any strength gains that can be induced through cognitive strategies (i.e meditation, imagery training) will be appreciated.
Effects of training taper on blood levels of cortisol (C), testosterone(T) , the ratio of testosterone to Cortisol(T/C), growth hormone(GH), creatine kinase enzyme (CK) and concentration of lactic acid(LA) ?
I am looking for a study which I can use to start a discussion about the use of nutrition for recovery after sport exercices. As I have to represent some negative effects (even if so little exist) and as my colleagues in class do speak about the positive effect of chocolate milk as a recovery beverage, I have to find something to criticize their studies or maybe find something better than carbohydrate-protein drinks.
which method is recommended to inducing diabetes type 2 in mice for studying mitochondrial dysfunction?
Drug (streptozotocin) or high fat diet?
and also any other useful information about the type and age of mice?
After inducing diabetes, 8 week exercise training will be conducted.
Thanks in advance.
Can anybody recommend leading researchers in that field or knows anything oneself about sport and fasting nor sport, fasting and metabolic syndrome?
Thank you for your help!
i have been training so hard for the past two weeks and today throughout the day I was having a running stomach. Last year I was training athletics team during their preparation for the cross-country competition, and most of them were complaining about their running stomach. I interviewed them about the type of diet and amount of fluid they are taking, but it was a good diet and approximately 5-8 litres of water they drank per day(before, during and after training). I'm trying to find out if you guys you have a solution for this encountered solution. i want to know the physiological changes that takes place in the body that resulted in this situation
2. Does it affect the performance or other markers (testosterone) in athletes?
The following meta-analysis is attached and hope for their valuable opinions. Thanks!
¿Energy substrate or protein synthesis?
In case of protein synthesis, Does this happen at the expense of AMPK?
I am only curious, since I'm working on some sports nutrition research.
Has there ever been any research into nutritional practices concerning musicians, especially singers, actors/ performing artists or dancers in order to optimize their performance specifically?
I am aware that dancers may be the most appropriate for this so I'm looking more into musicians or actors - Not particularly pop culture celebrities.
I am looking to provide a dietary plan for 18-25yr old footballers, who have a body percentage over 25%? What are the proper guidelines to lose fat but minimize the risk of injury. Any advice will help. Thanks.
Is there a study that has measured resting metabolic rates on people after different nutrition interventions, like ketogenic diet versus ordinary western diet?
I'm looking into the effectiveness of caffeïne, especially when combined with a carbohydrate-rich meal. I have found some evidence for this but the number of studies investigating the effect of caffeine with and without a meal is very slim. Is there anyone that could enlighten me on this subject?
The main article that lead me on this path is an article by Tina Skinner and colleagues on the effect of caffeine in rowers. They found no ergogenic effect of caffeine, while other studies on rowers found the typical 1-1,5% improvement in power output.
Ultra-structural damage including plasma membrane impairments and damage to the sarcoplasmic reticulum have been observed following unaccustomed eccentric exercise (Warren et al., 1993 Friden et al., 1993., etc). My question is, is there any possibility that omega-3 fatty acids may play a role in maintaining plasma membrane integrity and the subsequent reduction in membrane permeability and Ca2+ concentration?
Some time ago I read in a sport paper (probably Volek JS, but I do not remember) which said that women habitually under-reported when answer different dietary records.
I work with female athletes and always when I calculate their nutritional intake, with 7- days records or validated food frequency questionnaire, see low energy intake and macronutrients, specially carbohydrates.
I think a possible justification, they do not write every food which eat.
I am working with elite female volleyball players and i do not know what equation to use to RMR and total energy expenditure.Depends which uses, differences of up to 400 kcal.
Athletes often respond quickly to new concepts and often manipulate their training or dietary practices before the confirmatory research can be completed. As such, research that proves a concept wouldn't further inform since they are already doing it! Therefore advice showing no effect or even a detrimental effect could be seen as more useful?
A limited number of trials have been carried out on the efficacy of the "Paleo" diet for improving metabolic health outcomes (see attached pub). Additionally a wave of interest has sprung up around the use of the "Paleo" diet for improving sport performance.
The contention is that we evolved to consume this diet and therefore it is "better" for our health than a diet composed of grains/dairy and products not available to Palaeolithic man. However, is the evidence base strong enough to recommend this diet in either clinical or athletic populations?
Please base your responses on evidence based and peer reviewed research.
Is possible that female athletes with light level of muscle mass, have low levels of muscle damage?
