Physical fitness applies to being the physiological condition in relation to optimal physiological and body-movement functioning .Many people engage in physical fitness to maintain or improve their physical appearance. However, physical fitness not only could improve body health, but also could improve mental health (Chung & Baird, 124).
Regular exercise is one of the best things that a person can do to help prevent illness and preserve health. Regular exercise makes the cardiovascular system more efficient at pumping blood and delivering oxygen to the exercise muscles. Releases of adrenaline and lactic acid into the blood result in an increase of the heart rate. Regular physical activity can also improve mood and the way you feel about yourself. Exercise is likely to reduce depression and anxiety and help you to better manage stress.
Exercises increase some of the different components of the cardiovascular system such as stroke volume, cardiac output, systolic blood pressure (SBP), and mean arterial pressure.
There are two types of physical fitness that can help improve mental health: Aerobic, means ‘with oxygen’ and Anaerobic, means ‘without oxygen’.
Aerobic Exercise: This term refers to exercise that requires oxygen from the air to get to the muscles, thus the heart and lungs are forced to work harder than normal. Running, biking, swimming, and skating are examples of aerobic exercise. Aerobic exercise tends to burn a great deal of calories and improves cardiac function more than does anaerobic exercise. However, it is less effective at building strength and muscle mass.
Anaerobic Exercise: This term refers to exercise that requires intense straining for short periods of time. Sprinting, vaulting, basketball and resistance training (weight-lifting) are the examples. Anaerobic exercise relies on energy sources that are stored in the muscle and, unlike aerobic exercise, is not dependent on oxygen from the air. Overall, anaerobic exercise burns fewer calories than does aerobic exercise and may be somewhat less beneficial for cardiovascular fitness (Chung, B. & Baird, K. 124-126).......................
