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.
Different physical activities cause the heart to beat at different rates. Moderate physical activity corresponds to a heart rate of 50 to 60 percent of maximum, or 93 to 157 beats per minute for a 35-year-old. Increasing your heart rate to 60 to 70 percent of maximum improves cardiovascular endurance and burns fat.oderate physical activity corresponds to a heart rate of 50 to 60 percent of maximum, or 93 to 157 beats per minute for a 35-year-old.
