Answer 1

Sure! Here’s a matching of each energy system with the duration of exercise it primarily supports:

1. **PCr-ATP Energy System**: This system supports **short-duration, high-intensity exercise** (approximately 0-10 seconds).

2. **Lactic Acid Energy System**: This system supports **moderate-duration, high-intensity exercise** (approximately 10 seconds to about 2-3 minutes).

3. **Oxygen Energy System**: This system supports **long-duration, low to moderate-intensity exercise** (over 3 minutes, ongoing aerobic activities).
