Nutrition for Performance Background • •

•

Food provides the body with fuel for everyday activities. Athletes require different nutrient intakes to produce higher energy, more muscle, and a faster recovery period. Macronutrient needs must be met during exercise to replenish glycogen stores and repair muscular tissue.

Relevance to the Field •

•

Improper nutrition can cause stress, fatigue, and metabolic waste accumulation, increasing risk of injury and a negative impact on performance. Low energy intake for athletes can result in loss of muscle mass, failure to gain bone density, and prolonged recovery, impeding athletic performance.

Carbohydrate Needs Carbohydrate requirements for an athlete range from 6-10 g/kg of body weight per day to maintain blood sugar levels and improve cognitive functioning.

Protein Needs Protein requirements are often higher for athletes to compensate for a increased muscular demand. An athlete needs 1.2-2.0 g/kg of body weight per day.

Fat Needs The fat requirements for an athlete verses a non-athlete are about the same, making up 20-35% of daily caloric intake.

Effects on Performance •

•

•

Before performance: 1-4 g/kg of body weight are needed to utilize muscle glycogen and prevent hypoglycemia. Beverages should be drank slowly 4 hours prior to performance to help retain fluid during exercise. During performance: Carbohydrates should be ingested prior to fatigue, approximately 30-90 g/hr, to regulate heart rate, internal temperatures, and prevent dehydration. After performance: Because glycogen and protein synthesis are highest after exercise, carbohydrates and protein should be ingested within 30 minutes of performance and at 2hour intervals for the next 6 hours after the event to increase muscle stores.
