To achieve ideal strength/power to mass ratio, athletes may attempt to lower body mass through reductions in fat mass (FM), while maintaining or increasing fat-free mass (FFM) by manipulating their training re https://alimentos-carbohidratos.com…
Based on a comprehensive review and critical analysis of the literature regarding the effects of sodium bicarbonate supplementation on exercise performance, conducted by experts in the field and selected membe…
Endurance athletes typically consume carbohydrate-rich diets to allow for optimal performance during competitions and intense training. However, acute exercise studies have revealed that training or recovery w…

Blends of protein sources might afford a favorable combination of key nutrients such as leucine, EAAs, bioactive peptides, and antioxidants, but more research is needed to determine their ideal composition.
Exercise increases skeletal muscle reactive oxygen species (ROS) production, which may contribute to the onset of muscular fatigue and impair athletic performance. Mitochondria-targeted antioxidants such as Mi…
Taking each of these variables into consideration, the effects of supplemental protein consumption has on maximal strength enhancement are varied, with a majority of the investigations reporting no benefit and a few reporting improvements in maximal strength . With limited exceptions , most of the studies utilized young, healthy, untrained males as participants. In one investigation examining college football athletes supplementing with a proprietary milk protein supplement (two servings of 42 g per day) for 12 weeks, a 14.5% increase in maximal squat strength was observed compared to a 6.9% increase in the placebo group . These differences were statistically significant. When females were the only sex investigated, the outcomes consistently indicated that supplemental protein does not appear to enhance maximal strength at magnitudes that reach statistical significance. Hida et al. reported that females supplementing with 15 g of egg white protein (which raised daily protein intake to 1.23 g of protein/kg body weight/day) experienced no improvements in maximal upper and lower body strength as compared to a carbohydrate placebo (ingesting one gram of protein/kg body weight/day) over an 8-week period. An important note for this study is that 15 g of egg protein is considered by many to be a sub-optimal dose . However, others have advocated that the total daily intake of protein might be as important or more important . In another study, Josse et al. reported that non-resistance trained females supplementing with one liter of skimmed bovine milk (providing 36 g of protein) after resistance exercise improved maximal strength in seven of nine measures as compared to a carbohydrate placebo group, but only the improvements to maximal bench press strength attained statistical significance compared to the placebo. In contrast, Taylor and colleagues reported that pre- and post-exercise whey protein ingestion significantly increased maximal upper-body strength (+4.9 kg bench press one repetition maximum) in comparison to changes seen when a maltodextrin placebo (+2.3 kg) was ingested in a group of female collegiate basketball players over an 8-week period.

Sports nutrition supplements
One of the top supplements for athletes is protein powder. There are many types of protein powder on the market, such as whey, casein, egg, pea, hemp, mixed plant, and more. Taking protein powder before you workout can maximize your muscle gain. Athletes often use whey protein products to prepare for competition because they get fast results.
When hard-training athletes don’t eat enough, they may experience a condition known as Relative Energy Deficiency in Sport, or RED-S.3,5,6 Besides leading to a decline in athletic performance, RED-S can negatively affect an athlete’s:
It’s important to keep in mind that there are NCAA regulations that can disqualify a competitive athlete for having too much caffeine in their system. Under NCAA rules, athletes who are found to have more than 15 micrograms of caffeine per milliliter in a urine test could face a yearlong suspension.
A review of research published in January 2021 in the Journal of the International Society of Sports Nutrition found that caffeine can improve aerobic endurance and athletic performance when consumed in doses of 3 to 6 milligrams per kilogram of body mass. This is the equivalent of 273-545 milligrams for a 200-pound athlete. For reference, a cup of brewed coffee contains around 100 milligrams.
More research is needed to clarify the potential benefits of nitrate supplementation from beetroot juice on exercise and athletic performance and to determine the best doses and dosing protocols . No research has assessed longer term supplementation with beetroot-derived nitrate beyond several weeks as an ergogenic aid.
