of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise‚ we measure the breathing rate before physical activity by counting the number of breaths in 10 seconds
