Sample Answer
- Essential for aerobic activities like long-distance running as carbohydrates provide the main source of energy through glucose breakdown in the presence of oxygen.
- Less important for anaerobic activities like sprinting as these rely primarily on stored ATP for immediate energy rather than carbohydrate breakdown.
- Affects energy availability differently: aerobic activities require constant supply of carbohydrates to maintain blood glucose levels while anaerobic activities use stored energy.
- Influences activity duration as aerobic athletes need regular carbohydrate consumption to prevent fatigue while anaerobic athletes focus on pre-exercise carbohydrate intake.
- Impacts energy system efficiency as adequate carbohydrate intake ensures optimal function of both aerobic and anaerobic systems during their respective activities.
