Position Statement
- Post-performance nutrition proves more critical for endurance athletes than power athletes.
- This is due to greater glycogen depletion and extended recovery requirements following prolonged exercise.
Endurance Athletes’ Greater Needs
- Endurance events significantly deplete muscle and liver glycogen stores through sustained aerobic energy system demands over extended periods.
- Evidence demonstrates that endurance athletes experience substantial fluid losses through prolonged sweating, requiring immediate replacement of 125-150 percent of fluids lost.
- Research shows endurance performance relies heavily on carbohydrate availability, making rapid glycogen restoration essential for subsequent training capacity.
- Post-performance nutrition aims to return the body to its pre-event state as quickly as possible, enabling full training to resume.
- Studies indicate that delayed carbohydrate intake following endurance events compromises glycogen resynthesis and prolongs recovery periods.
Power Athletes’ Lesser Requirements
- Power athletes typically complete shorter duration activities that rely primarily on ATP/PCr energy systems with minimal glycogen depletion.
- These events generally produce less fluid loss and metabolic disruption compared to prolonged endurance activities.
- Recovery demands focus more on neural system restoration rather than extensive fuel and fluid replacement.
Reinforcement
- While all athletes benefit from post-exercise nutrition, endurance athletes face greater physiological demands requiring more immediate and comprehensive nutritional intervention.
- Therefore post-performance nutrition strategies must be prioritised for endurance athletes to maintain training quality and competitive performance.
