Various types of physical exercises

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 the 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 running, cycling, swimming, brisk walking, skipping rope, rowing, hiking, dancing, playing tennis, continuous training, and long distance running.Endurance, or aerobic, activities increase your breathing and heart rate. They keep your heart, lungs, and circulatory system healthy and improve your overall fitness.
  • Anaerobic exercise, which includes strength and resistance training, can firm, strengthen, and increase muscle mass, as well as improve bone density, balance, and coordination. Examples of strength exercises are push-ups, pull-ups, lunges, squats, bench press. Anaerobic exercise also includes weight training, functional training, eccentric training. Strength, or resistance training, exercises make your muscles stronger.
  • Flexibility exercises stretch and lengthen muscles. Activities such as stretching help to improve joint flexibility and keep muscles limber. The goal is to improve the range of motion which can reduce the chance of injury. Flexibility exercises stretch your muscles and can help your body stay limber. Yoga and doing various stretches can make you more flexible.

Health benefits

Physical exercise is important for maintaining physical fitness and can contribute to maintaining a healthy weight, regulating the digestive system, building and maintaining healthy bone density, muscle strength, and joint mobility, promoting physiological well-being, reducing surgical risks, and strengthening the immune system. Moderate levels of exercise have been correlated with preventing aging by reducing inflammatory potential.Fitting regular exercise into your daily schedule may seem difficult at first. But you can start slowly, and break your exercise time into chunks. Even doing ten minutes at a time is fine. You can work your way up to doing the recommended amount of exercise.

Other health benefits

The beneficial effect of exercise includes your cardiovascular system as well. There is a direct correlation between physical inactivity and cardiovascular mortality, and physical inactivity is an independent risk factor for the development of coronary artery disease. Low levels of physical exercise increase the risk of cardiovascular diseases mortality. Children who participate in physical exercise experience greater loss of body fat and increased cardiovascular fitness. Studies have shown that academic stress in youth increases the risk of cardiovascular disease in later years; however, these risks can be greatly decreased with regular physical exercise.
Epidemiological evidence suggests that moderate exercise has a beneficial effect on the human immune system. Moderate exercise has been associated with a 29% decreased incidence of upper respiratory tract infections. A number of medical reviews have indicated that exercise has a marked and persistent antidepressant effect in humansSeveral systematic reviews have analyzed the potential for physical exercise in the treatment of depressive disorders.
