NUTRITION FOR
ATHLETIC
PERFORMANCE
Kinesiology Major 100
By: Ms. Perry
WHO “IS” AND WHO “IS NOT” AN ATHLETE?
Someone who is elite in their sport?
Someone who competes regularly?
Someone who exercises everyday?
There is no set protocol to establish who is and who
is not an athlete, therefore, you must decide based
on sound judgment.
Anyone who goes “above and beyond” the basic
exercise recommendations for health benefits.
WHY IS NUTRITION IMPORTANT FOR
ATHLETES?
Provide general health benefits
Maintain an appropriate body composition
Maximize athletic performance
WHAT CHANGES ARE MADE FOR ATHLETES?
Macronutrient daily recommendations
Caloric requirement
Intake before, during and after a training bout or
competition
Hydration and fluid replacement
Consideration of the use of sports drinks and
other products
MACRONUTRIENT INTAKE FOR THE
GENERAL POPULATION
50-55% of calories from carbohydrate
10-15% of calories from protein
Less than 30% of calories from fat
MACRONUTRIENT INTAKE FOR ATHLETES
55-60% (or sometimes higher) of calories from
carbohydrate
10-15% of calories from protein
Less than 30% of calories from fat
The main difference is in the amount of
carbohydrate, for both resistance and endurance
athletes!!! Why?

IMPORTANCE OF CHO
Plays a critical role in athletic performance
Primary energy source
Cause of fatigue in athletes
Muscle glycogen in depletion
Liver glycogen depletion
Diet is critical to replenish CHO stores
EVENTS TAXING CHO STORES
One hard competition
Multiple events in one day
Exhaustive daily training
Two-a-day workouts
High-power, intermittent workouts
CONSEQUENCE OF LOW CHO DIETS
Slow repletion of glycogen stores
Fatigue
Impaired training and performance
Injury
FAT INTAKE RECOMMENDATIONS
Essential part of a healthy diet
No benefit (may actually be detrimental) when fat
intake
