Most people have heard exercise is good for your body. But how exactly does exercise effect your body one way or another? According to Touhy and Jett (2014) “recommendations for all adults are participation in 30 minutes of moderate-intensity physical activity for five or more days of the week. However, for adults 65 years of age or older without limitations should have 150 minutes of moderate-intensity aerobic activity every week and muscle strengthening activities on two or more days that work all major muscle groups” (p.177). When we exercise, the GI tract has improved appetite, increase tract tone and facilitates peristalsis. The negative side to not exercising regarding the GI tract would be constipation.
Exercising really helps “improve your heart and reduces the risk of obesity, heart disease, hypertension and hear failure. However, those that overexert themselves with strenuous activity can develop an abnormal rhythm, atrial fibrillation and can also change the structure of the heart and the blood vessels” (Amy, n.d., para. 2).
Some people may not realize but exercise also helps with psychosocial factors such as “having a better tolerance to stress, report feeling better in general and often time people report a decrease to illness” (Porter, Perry, Stockert, & Hall, 2013, p. 753).
Over-exerting oneself can also have a negative effect on your immune system. When you over exercise, your body becomes exhausted and can’t fight off the infection or illness that is attacking your body. Normally, your immune system becomes weak 3-24 hours after working out, but once you over do it, it can take weeks for your body to fight the infection (Amy, n.d.).
