During exercise, in order to obtain energy, muscles have to burn carbohydrates and lipids, which causes the production of heat. The increase in metabolism during exercise increases the body’s core temperature (Burton, 2004). Circulating blood flow is used to transport the excessive metabolic heat produced by the working muscles. The heat is transported to the surface of the body and it is released to the environment. Radiation, convection or by evaporation of sweat, are the three main ways the body gets rid of excessive heat (Fortney, 1985). The hypothalamic neurons control the body temperature (Soare, etl,2011). These neurons modulate the autonomic and hormonal control of heat production and heat loss. This allows for the constant maintenance of core body temperature when the environment temperature changes (Soare, etl,2011). When the core body temperature is at an ideal temperature, the internal organs and the bodily systems work at their best. The ideal temperature to be at is 98.6 F. Having it below 96 F or over 100 F the organs and systems will not work properly. Exercise sessions performed 2-3 times a week can help improve cardiovascular fitness (White, 2013). Not being active enough increases the risk of cardiovascular disease, diabetes, and other disorders. Over time, exercise reduces cardiovascular risk, reduces blood pressure and decreases insulin resistance (Cohen, 2013). The cardiovascular system is a direct beneficiary of increased physical activity. Exercise can minimize the effects of aging on the cardiovascular system and improve circulation, heart function, blood fat lipid levels, and reduce blood pressure. On the other hand, people who live a sedentary life are more prone to cardiovascular disease (Exercise for ... ...s that exercise will have on the body. Oxygen demand increases when doing a physical activity. This causes the person to breath heavy. During exercise, the respiratory rate will elevate and might remain elevated after heavy exercise for up to 1–2 h. During strenuous exercise, the heart rate and stroke volume increase to about 90% of their maximum values. The body can never use oxygen at a higher rate than the rate at which the cardiovascular system can transport oxygen to the tissues (Burton, 2004). Staying physically fit will lose body fat, increase energy, and improve confidence (Bergen, 2013). To prevent weight gain, 150-250 minutes of moderate exercise a week is recommended. People that exercise have decrease in body fat and an increase in quality of life. Their energy level was also measured and they scored higher than the controlled group (Burnham, 2002).
