The hypothalamus is a part of your brain that controls body temperature. When you exercise, your body temperature increases, causing the hypothalamus to signal the brainstem to further increase your heart rate.
The heart rate during exercise is an indicator of intensity, or in other words how hard you are working. As you get fitter, your heart rate should decrease for any given exercise workload. This is the basis of many of the submaximal aerobic fitness tests.During exercise, your heart rate will depend on the intensity of exercise, your fitness level, and your maximum heart rate (which may also depend on your age).Some training programs set the intensity of exercise using heart rate guides.he heart rate during exercise is an indicator of intensity, or in other words how hard you are working.
