NUTR 424: QUIZ 6Discuss 3 ways caffeine impacts exercise performance.
- Caffeine impacts exercise performance by increasing energy expenditure and fat release.
- Caffeine directly stimulates the central nervous system, heightening awareness and decreasing
perception of effort. Because of its glycogen-sparing effect, caffeine may help in endurance
exercise.
- Caffeine may also help with high-intensity exercise, but there is not much benefit seen with
strength/power performance.
Fat cannot be stored in muscle.
