Study Notes
- ATP provides the energy needed for bodily work, with different energy systems being used based on exercise duration and intensity.
Alactic System
- Small amounts of ATP stored in muscles fuel high-intensity activities lasting a few seconds.
- The alactic system relies on creatine phosphate (CP) to resynthesize ADP into ATP.
- The cycle continues for around 10-12 seconds, ceasing when CP supplies are depleted, leading to fatigue.
- Recovery takes approximately 2 minutes, allowing athletes to repeat movements after a short break.
Aerobic System
- The aerobic system provides energy for low-to-moderate intensity activities (up to 80% MHR) lasting over 2-3 minutes.
- Glycogen from carbohydrate breakdown is used to continuously create ATP.
- The process yields CO2 and H2O by-products but produces large amounts of ATP.
- After 1-2 hours, glycogen stores deplete, and the body utilizes fats as a fuel source.
- Since fats require more oxygen to break down, faster breathing is necessary.
- Fatigue results from the inability to supply enough oxygen or running out of fuel.
- It takes 24-48 hours for the body to replenish glycogen stores.
