Exercise is bodily activity that helps for the development and maintenance of physical fitness and overall health. It strengthens musculoskeletal and cardiovascular system; even the socio-psychological aspects of a person and it hone athletic skills. Today, it is necessary for individuals to recognize the vital role exercise plays in their well being. It maximizes lung capacity, helps boosts immune system and helps prevent health problems such as cardiovascular diseases, diabetes and obesity. It also improves mental health and performance and may prevent or alleviate depression. Since the 1970s, exercise has become inoculated into the culture of our society, and the importance of exercise as a preventive and rehabilitative measure is widely recognized. Exercise affects people’s moods. After one hour of running or strenuous exercising, most people feel physically exhausted but mentally relaxed, if not slightly euphoric. Physical exercise is known to stimulate the synthesis of endorphins, which might explain this feeling of well-being and fills the role of a mild antidepressant.
Exercise helps develop the hippocampus-dependent spatial learning, leading to improvement of cognitive functioning and boosts synaptic plasticity and neuronal growth. Moreover, it serves as a neuroprotectant in many neuromuscular and neurodegenerative diseases such as dementia. Exercise has an effect on the catabolism of the body, resulting to improved endurance, muscular strength, bone density and toughness of connective tissues. Brain chemicals such as dopamine, norephinephrine, serotonin and glutamate that help cognitive functions are increased when regular exercise is maintained. But excessive or inappropriate exercise could be detrimental. Without proper rest, there is an increase chance of stroke or other circulatory problems. Rhabdomyolysis results from unaccustomed overexertion of muscles and sudden change in endorphin production due to abrupt stoppage of excessive exercise could lead to depression or agitation. Performing exercises with family, friends and other people could lead to emotional and social fulfilment. With all this benefits, we can really say that exercise is good for our mind, body and soul (Bailey, 1996).
