How much does my heart rate change after running in place for 10 minutes? Introduction The leading cause of death in the US is heart disease and the fourth leading cause of death in the US is stroke. Both are related to the heart. Both can be prevented (or at least somewhat alleviated) by engaging in exercise. Among the other leading causes of death is diabetes, which is related to being obese (and therefore sedentary). Exercise can reduce the chance of becoming diabetic and is also important in managing diabetes. In fact, 250,000 deaths in the US can be credited to leading an exercise-free lifestyle. Less than 1/3 of adults actually do enough physical activity. Heart rate is the amount of times the heart beats per minute. The heart beats every time the muscle contracts in order to pump oxygen through the medium of blood throughout the body. When you exercise, your muscles need more oxygen in order to undergo cellular respiration for energy. Therefore, during exercise the heart must contract more often for the muscles to receive sufficient oxygen. However, how much faster is related to the fitness level of each individual and the intensity of the exercise. Therefore, understanding how a physical activity, such as running in place for 10 minutes, affects heart rate can help us understand cardiovascular health and possibly preventing cardiovascular diseases. Research and Current Ideas Resting heart rate is the amount of times a heart beats per minute (bpm) when the individual is sitting or lying down without having previously engaged in intense of physical activity. In other words, the resting heart rate is taken when the heart is working the minimum so at the very least the individual remains alive.
