Formula 1 drivers require a daily high-carbohydrate (CHO) diet to maintain stamina and replenish lost glycogen stores during practice, competition and/or weight training. Athletes who need to remain mentally focused for prolonged periods of time must keep their liver glycogen stores filled. Liver glycogen is the primary fuel that the brain uses for energy, and when the stores are low, focus and timing begin to suffer.

The ability to concentrate for long periods of time can determine the outcome of the race in those final laps. Because F1 Racing has an element of strength-endurance, anaerobic performance, and concentration, we can take this information and apply it in a context applicable to F1 Racing. Some general guidelines to follow on a daily basis are:

Power athletes like beach volleyball players require the majority of daily food intake to come from carbohydrates (CHO), which help maintain stamina and replenish lost glycogen stores (i.e. stored carbohydrates in muscle) in the muscle and liver during practice, a game and/or weight training. Liver glycogen is the primary fuel for energy. When the stores are low, focus and timing begin to suffer.

In the Pre-Season, the training diet for basketball players should remain the same as the Off Season in terms of 60 percent CHO, 20 percent fat and 20 percent protein. However, the athlete should not be trying to lose or gain weight. The focus should be on maintaining the current weight and on becoming stronger and more powerful.

Just like carbohydrates and protein, not all fats are equal in the way they affect your body. The "healthy" fats are the types required for health, energy production, regulation of cell functions and healing. Many of these are the essential fatty acids (EFAs) or the fats we need from our environment that the body does not produce, such as linoleic acid.,

During the 1980's, the diet-rage was low-fat, high-carbohydrate. During the 1990's, the rage was low-carbohydrate, high-fat. Today, the latest and greatest "discovery" is the glycemic index (GI). As discussed above, the GI is a measurement of the way the blood sugar responds two hours after an equivalent amount of pure glucose is ingested. Foods that are digested quickly and soon appear in the bloodstream have a high GI and raise blood sugar and insulin concentrations quickly.

Persistent fatigue, poor recovery, illness and unwanted weight loss are common amongst triathletes who fail to meet daily energy and nutrient requirements. A nutrition program must be the core of a triathlete's training program in order to fuel, adapt and recover from each workout. Nutrition is important not just to finish, but to perform at the highest level throughout the race.

The triathlon is an intense test of physical and mental endurance, with competitions sometimes stretching to the grueling 14-hour mark. Triathletes must master three disciplines (running, swimming and cycling) to be successful, so the training has to involve two of the three disciplines regularly - and nutrition needs to be a top priority.

The athlete wants to maintain proper protein intake to maintain optimal performance of the above functions and to prevent any tissue breakdown of muscle for energy. However, this doesn't mean that more protein is better. A gentle balance must still be maintained between the calorie-protein ratio. Excess protein will be converted to fat and there may be an increase in a toxic byproduct of protein metabolism called.,

A great deal of the literature on nutrition for wrestlers deals with the extreme psychological pressure put upon athletes to "make weight." This is a serious problem within the wrestling community. In late 1997, three previously healthy collegiate wrestlers in different states died while each was engaged in a program of rapid weight loss to qualify for competition.

Wakeboarders require a daily moderate-carbohydrate (CHO) diet to maintain stamina, replenish lost glycogen stores, and fuel the ATP/CP system (i.e. the "power system") during practice, competition and/or weight training. Wakeboarders are powerful athletes who need to produce explosive movements repeatedly throughout the day.

Tennis players have to be agile, explosive, quick and strong. Players need to be prepared with proper fuel and hydration. Because we understand the energy systems involved in tennis, we can develop food strategies to fortify players and ensure optimal performance. Our recommendations are speculative, but our general guidelines are based on scientific evidence. The guidelines are as follows:
