QUESTIONS FOR CRITICAL THINKING AND REFLECTION
When you think about the types of physical activity you engage in during your typical day or week, which ones use the immediate energy system? The nonoxidative energy system? The oxidative energy system? How can you increase activities that use the oxidative energy system?
Physical Fitness and Energy Production Physically fit people can increase their metabolic rate substantially, generating the energy needed for powerful or sustained exercise. People who are not fit cannot respond to exercise in the same way. Their bodies are less capable of delivering oxygen and fuel to exercising muscles, they can’t burn as many calories during or after exercise, and they are less able to cope with lactic acid and other substances produced during intense physical activity that contribute to fatigue. Because of this, they become fatigued more rapidly; their legs hurt and they breathe heavily walking up a flight of stairs, for example.

Regular physical training can substantially improve the body’s ability to produce energy and meet the challenges of increased physical activity.
In designing an exercise program, focus on the energy system most important to your goals. Because improving the functioning of the cardiorespiratory system is critical to overall wellness, endurance exercise that utilizes the oxidative energy system activities performed at moderate to high intensities for a prolonged duration is a key component of any health-related fitness program.
