Although there is a plethora of information available regarding the impact of nutrition on exercise performance, many recommendations are based on male needs due to the dominance of male participation in the n…
In conclusion, added protein does not appear to improve endurance performance when given for several days, weeks, or immediately prior to and during endurance exercise. While no ergogenic outcomes may be evident, the scientific literature is consistent in reporting that adding protein to a carbohydrate beverage/gel during exhaustive endurance exercise suppresses markers of muscle damage (creatine kinase) 12 to 24 h post-exercise and decreases the endurance athletes’ feelings of muscular soreness . For these reasons, it seems prudent to recommend for endurance athletes to ingest approximately 0.25 g of protein/kg body weight per hour of endurance exercise (in addition to the athlete’s regular carbohydrate intake) to suppress markers of muscle damage and improve subjective feelings of muscular soreness . Another important consideration relates to the impact of ingesting protein along with carbohydrate on rates of protein synthesis and balance during prolonged bouts of endurance exercise. Beelen and colleagues determined that adding protein to carbohydrate consumption throughout a prolonged bout of endurance exercise promotes a higher whole body net protein balance, but the added protein does not exert any further impact on rates of MPS. While performance outcomes were not measured, these results shift the focus of nutrient ingestion during prolonged bouts of endurance exercise to the ingestion of carbohydrate.

In their study, Pelly et al. studied the diet of athletes participating in major international competitions during the 2010 Commonwealth Games in Delhi. In total, 351 athletes were questioned. Most athletes (62%) reported following one or more dietary regimens, with 50% following a nutritional-based diet. Athletes from weight classes and esthetic (28%) and strength/sprint (41%) sports followed low-fat and high-protein regimens, respectively. Other specialized diets were followed by 33% of the participants, with the most frequently reported avoiding red meat (13%), vegetarian diets (7%), halal (6%), and low lactose (5%) diets. More athletes from non-Western regions followed a vegetarian diet, while more vegetarians reported avoiding supplements and wheat .
Sport-related nutritional supplements (SRNSs) include sport drinks, sport bars, and sport gels. Previous studies indicate that 25–35 % of athletes and 25–50 % of military personnel report using these supplemen…
In addition, the development of valid and reliable questionnaires can provide a valid and reliable tool for assessing voluntary dietary restrictions on food choices, reasons for food refusal, and gastrointestinal symptoms among athletes and, consequently, to optimize their performance .
According to a study , there is a growing interest in plant-based diets, especially in relation to vegan diets and semi-vegetarian or flexitarian diets among athletes. Approximately 8% of international athletes follow a vegetarian diet, and 1% are vegans .
American-style football (ASF) athletes are at risk for cardiovascular disease (CVD) and exhibit elevated levels of serum neurofilament light (Nf-L), a biomarker of axonal injury that is associated with repetit…
Previous investigations have found positive effects of acute ingestion of capsules containing 4-to-9 mg of caffeine per kg of body mass on several aspects of judo performance. However, no previous investigatio…

The TANS tool is a valuable resource for physicians. It allows them to identify critical nutrient intake in the military, fire, and law enforcement personnel, as well as individuals in other high-risk occupations.
Established by one of the world’s premier doping control laboratories in 2008, LGC established informed Sport as a globally acclaimed banned substance testing and certification programme for sports supplements.
A recent study found that athletes have an increased need for protein. Researchers measured how much athletes ate in grams per kilogram of body weight. The results showed that they need more than the recommended daily amount.
Beta-alanine is another potentially beneficial nutrient for soldiers. Beta-alanine has been shown to reduce muscle soreness and neuromuscular fatigue, two important factors that limit high-intensity exercise.
The Informed Sport program is a dietary supplement resource and risk minimization for the military community and leaders. Choose tested products that will improve armed forces sports nutrition by looking for the Informed Sport logo or on-pack descriptor on product packaging, along with searching for the specific batch/lot number on Informed-Sport.com or the Informed Sport mobile app to confirm batch testing.
