In animal models, studies commonly report that increases in bicarbonate concentration and/or intracellular accumulation of H+ do not impact maximum force production, even though these effects may be temperature-dependent [192, 193]. This lack of an effect on force production might also explain why sodium bicarbonate supplementation in humans generally does not enhance maximum strength. However, data using animal models also show that a decline in pH negatively affects muscle conduction velocity, a metric that is positively related to the rate of force development (RFD) [194, 195]. Given that one of the mechanisms of sodium bicarbonate is buffering of H+, the ingestion of this supplement may positively impact RFD. A series of studies explored the effects of sodium bicarbonate on RFD following either 30 s of cycling, maximum strength testing, or five sets of knee extensions [104, 106,107,108]. RFD was higher following sodium bicarbonate ingestion in three of these studies. These findings might be of practical importance as RFD is associated with several aspects of athletic performance, such as sprinting and jumping [196, 197]. This might partially explain some of the positive results shown for the effect of sodium bicarbonate supplementation on repeated-sprint activities. While these initial findings are promising, future work is still needed, as only a few studies have focused on this outcome.

A sound nutritional plan is essential for achieving and maintaining optimal athletic performance. In addition to daily meal planning, a sports nutritionist pays special attention to the needs of athletes before, during and following training sessions and competitions. A wide variety of foods and nutritional products are available for the athlete to meet these needs. Sports nutrition professionals spend a lot of time reading and interpreting the relevant literature, and in many cases, researching the best products and ways to deliver the needed nutrients. In the research world, we often examine individual ingredients that have been removed from foods in an effort to examine the potential beneficial effects in isolation. In the real world, we most often eat foods that contain several important ingredients. So, it is ultimately also necessary to conduct research studies with real foods to determine how the food is received as a whole, and whether the important ingredients reach the target tissues in sufficient amounts, whether they interact with each other, and of course, whether beneficial effects are realized. This supplement examines the potential complications and benefits of eating foods in the context of achieving and maintaining optimal performance.
The Gatorade Sports Science Institute (GSSI) has been bringing sports nutrition and sports science researchers together for the past 30 years to address many issues that relate to the health, wellbeing and performance of athletes. Since 2012 this gathering has been known as the GSSI Expert Panel, which continued in 2017 with a meeting in October to discuss several nutritional issues that influence athlete performance. Following the meeting, the authors summarized the recent work in their topic area, resulting in the manuscripts in this Sports Medicine supplement (the sixth in a series supported by GSSI).
The next paper [4] of the supplement digs deeper into the roles that fruit-derived polyphenols may play in enhancing athletic performance and recovering from exercise-induced muscle damage. Polyphenols have antioxidant and anti-inflammatory properties and may enhance exercise performance by regulating the excess reactive oxygen species generation that have been implicated in fatigue development. Recovery from intensive exercise may also be improved by polyphenols by limiting inflammation and oxidative damage in muscle. While some research does exist to support these claims, more research is needed both from an efficacy and mechanistic perspective.

It is the position of the Academy of Nutrition and Dietetics, Dietitians of Canada, and the American College of Sports Medicine that the performance of, and recovery from, sporting activities are enhanced by well-chosen nutrition strategies. These organizations provide guidelines for the appropriate type, amount, and timing of intake of food, fluids, and supplements to promote optimal health and performance across different scenarios of training and competitive sport. This position paper was prepared for members of the Academy of Nutrition and Dietetics, Dietitians of Canada (DC), and American College of Sports Medicine (ACSM), other professional associations, government agencies, industry, and the public. It outlines the Academy's, DC's and ACSM's stance on nutrition factors that have been determined to influence athletic performance and emerging trends in the field of sports nutrition. Athletes should be referred to a registered dietitian/nutritionist for a personalized nutrition plan. In the United States and in Canada, the Certified Specialist in Sports Dietetics (CSSD) is a registered dietitian/nutritionist and a credentialed sports nutrition expert.
The Physical Training and Performance minor is designed for students interested in strength and conditioning. The minor provides students with an understanding of the theoretical and practical considerations associated with physical training (e.g., speed, agility, strength, endurance, flexibility, power) for improved athletic performance, fitness, and wellness.
This study aims to analyze the role of nutrients in food in improving athletic performance and to understand the feasibility of food supplementation in sports training. Twenty athletes were randomly divided into two groups, A and B. The athletes in the two groups had the same diet and the same training content and differed only in the supplemented food. Group A was supplemented with Siraitia grosvenorii water, and Group B was supplemented with pure water. After 3 months of training, the body composition, exercise status, and blood indexes of the athletes in the two groups were compared. Compared with the athletes in group A before the experiment as well as in group B after the experiment, the athletes in group A showed a significant increase in fat-free weight, improved athletic performance, increased levels of hemoglobin (Hb) and red blood cell (RBC), and decreased levels of blood lactic acid (BLA) and blood urea nitrogen (BUN) (P
Finally, we discuss what the latest scientific research indicates concerning the health implications of plant-based meat products, the best ways to transition to a more plant-forward diet, and specific fueling and supplementation strategies for building strength and athletic performance, among many other interesting topics.
There are certainly supplements than can help you with the nutrition portion of things. Protein shakes are beneficial if you have trouble meeting your daily protein requirements. Mass gainer shakes are beneficial is you have trouble meeting your daily calorie requirements. Creatine can help improve performance and can help you build muscle more efficiently if you struggle to get it through your diet as well. And, of course, water is the driver of all things.
Division I athletes at a single university were found to be in a state of hypohydration pre-practice (Volpe et al., 2009). Hypohydration stresses the cardiovascular system and reduces physical capacity, placing an athlete at a higher risk for musculoskeletal injury (Berning and Steen, 1991). In order to implement a successful hydration protocol, it is important that athletes, coaches, athletic trainers, and strength and conditioning professionals understand the importance of maintaining proper hydration and nutrition, as well as the critical components of hydration education (Casa et al., 2000).
Despite awareness of the status of dehydration and the negative effect it may have on performance, athletes often fail to practice appropriate hydration strategies. For example, previous research has shown that athletes generally lack knowledge of the appropriate markers for self-regulating adequate hydration levels (O'Neal et al., 2011; Yeargin et al., 2010). This may include a lack of clarity about appropriate targets for fluid intake, beverage types, and important information to monitor. Athletes are often unaware of the best methodologies for determining hydration status such as urine specific gravity, urine color, changes in body mass, plasma osmolality and bioimpedance. The National Athletic Trainers' Association (NATA) recommends the following practices regarding fluid replacement for athletic participation: athletes should begin a training session well hydrated by drinking approximately 500 to 600 ml of water or sports drink 2 to 3 hours before exercise and additional 200 to 300 ml of water or a sports drink 10 to 20 min before exercise. During the training session fluid replacement should approximate sweat and urine losses and maintain hydration at a level that keeps body weight loss to
