Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health or wellness. It is performed for various reasons. These include strengthening muscles and cardiovascular system, honing athletic skills, weight loss or maintenance and for enjoyment. Physical exercise boosts the immune system, and helps prevent the “diseases of affluence” such as heart disease, cardiovascular disease. It also improves mental health, helps prevent depression, helps to promote or maintain positive self-esteem, and can even augment an individual sex appeal or body image, which again is also linked with higher levels of self-esteem. Childhood obesity is growing global concern and physical exercise may help decrease the effects of childhood obesity in developed countries. Physical exercise is important for maintaining physical fitness and can contribute positively to maintaining a health weight, building and maintaining healthy bone density, muscle strength, and joint mobility, promoting physiological well being, reducing surgical risks, and strengthening the immune system. However exercise is a form of discipline. It means self-control and sincerity. We need to neglect our idleness. Physical exercise helps in character building. It makes our mind sharp and active. It improves mental strength and capability. It adds to our capability and improves our performance. Physical exercise done in morning keeps us healthy. Exercise also reduces levels of cortisol. Cortisol is as stress hormone that builds fat in the abdominal region, making weight loss difficult. Also Cortisol causes many health problems, both physical and mental. Regular aerobic exercise has been shown to help shown to help prevent or treat serious and life-threatening chronic conditions such as: Burns calories
Reduces the risk of chronic diseases like heart disease and diabetes Decreased blood triglycerides
Improve weight control
There is evidence that vigorous exercise is more beneficial than moderate exercise. Some studies have shown that vigorous exercise executed by healthy individuals can increase testosterone and growth hormone, effects that are not as us fully realized with moderate exercise. However, at this intensity for long periods of time, or without proper warm up beforehand and cool down afterwards, can lead to an increased risk of injury and overtraining. Both aerobic and anaerobic exercise also work to increase the mechanical efficiency of the heart by increasing cardiac volume (aerobic exercise), or myocardial thickness (strength training). Such changes are generally beneficial and healthy if they occur in response to exercise. Not everyone benefits equally from exercise. There is a lot of variation in individual response to training: where most people will see a moderate increase in endurance from aerobic exercise, some individuals will as much as double their oxygen uptake, while others can never enhance endurance. Also, muscle hypertrophy from resistance training is primarily determined by diet and testosterone. This genetic variation in improvement from training is one of the key physiological differences between professional athletes and usually people. I can say that exercising in middle age leads to better physical ability later in life. Beneficial effect of exercise on the Cardiovascular System
- Improved Heart Health:
The first one is an improved condition of your heart is a muscle just like any other and in order for it to become strong it must be worked. If you fail to work it, it will weaken over time and this can cause a variety of negative health effects. By getting the heart pumping at a faster rate on regular basis you will keep it in shape and healthy. Too many people are getting tired just performing simple exercises such as walking up the stairs and the primary reason for this is because they are neglect to work their heart muscle....
