Sharon is a 21-year old 200-meter runner, who now trains twice daily for 2-3 hours each session. Currently, her body fat is 12% and muscle mass is 31%. During her the sessions where she trains within 15 minutes of eating, she usually feels fatigued faster than sessions, where she trains 2- hours after eating. Discuss the following questions; 1. What are the possible implications of her body composition distribution on her physical performances? 2. What is the physiology of training within 15 minutes of eating, versus 2-hours after? 3. What energy systems are activated to complete her 21:54 second 200-meter run?
