Physical Activity vs. Exercise Five components of Health-Related Fitness: Cardiorespiratory endurance, Muscular strength, Muscular endurance, Flexibility, Body Composition Benefits of Regular Exercise: Improves cardiorespiratory function and decreases the risk of cardiovascular diseases. Increase metabolism. Improves body composition. May reduce the risk of some kinds of cancer. Protects against osteoporosis. Prevents the development of Adult Onset (Type II) diabetes. Improves social, psychological, and emotional wellness. Appears to boost immune function. Helps maintain good posture. Cardiorespiratory (Aerobic) Endurance; ability to continue vigorous activity for an extended period of time. Involves both cardiovascular and respiratory systems. Developed through regular, vigorous, continuous activity. Aerobic exercise requires the use of oxygen for energy production. It is a continuous exercise which is performed over an extended period of time (i.e running, walking, swimming, cross-country skiing, cycling). The energy required for exercise (both long and short term activity) is derived from: ATP- adenosine triphosphate ATP->ADP+Phosphate+Energy ATP energy can be supplied from three sources: 1. Stored ATP in the muscle. 2. Anaerobic metabolism 3. Aerobic metabolism (uses oxygen). How do I Improve Cardiorespiratory Fitness? The intensity of the exercise will affect the specific exercise prescription we use. For those interested in a low to moderate intensity program such as brisk walking, we can use the center for disease control’s (CDC) recommended guidelines: “to accumulate approximately 30 minutes of continuous exercise most days of the week.”
