Which energy system would be primarily in use during a long-distance jog?
  1. Oxidative system
  2. Glycolysis
  3. ATP-PC System
  4. Anaerobic glycolysis
Explanation
Answer - A - The oxidative system would be primarily in use during a long-distance jog. The ATP-PC system would be the first activated energy system, but only provides 10-15 seconds worth of energy and is used mostly for short-duration activities. Glycolysis provides about 30-50 seconds of energy and is ideal for a 400-meter run. Anaerobic glycolysis is part of the process of the glycolysis system.
