Exercise keeps the brain occupied, and keeps the Stress Hormone Cortisol in check which can lower symptoms for anxiety and restlessness, according to The Exercise Cure, by sports medicine physician Dr. Jordan Metzl.
Physical exercises are generally grouped into three types, depending on the overall effect they have on the human body:
- Aerobic exercise is any physical activity that uses large muscle groups and causes your body to use more oxygen than it would while resting. The goal of aerobic exercise is to increase cardiovascular endurance. Examples of aerobic exercise include cycling, swimming, brisk walking, skipping rope, rowing, hiking, playing tennis, continuous training, and long slow distance training.
- Anaerobic exercise is also called strength or Resistance training and can firm, strengthen, and tone your muscles, as well as improve bone strength, Balance, and Coordination. Examples of strength moves are pushups, lunges, and bicep curls using dumbbells. Anaerobic exercise also include weight training,functional training, eccentric training, Interval training, sprinting and high-intensity interval training increase short-term muscle strength.
- Flexibility exercises stretch and lengthen your muscles. Activities such as stretching help to improve joint joint flexibility and keep muscles limber. The goal is to improve the range of motion which can reduce the chance of injury.
Sometimes the terms 'dynamic' and 'static' are used. 'Dynamic' exercises such as steady running, tend to produce a lowering of the diastolic blood pressure during exercise, due to the improved blood flow. Conversely, static exercise (such as weight-lifting) can cause the systolic pressure to rise significantly (during the exercise).
