Detailed explanation-1: -Once exercise begins, the sympathetic nervous system is activated and the heart rate rises quickly. Heart rate also rises by simply thinking about exercise, which is referred to as anticipatory heart rate response. The parasympathetic division helps to slow down heart rate and respiration.
Detailed explanation-2: -When you exercise, the heart rate will increase, so blood can be pushed around the body faster, getting more oxygen and glucose to the muscles where it is needed to release energy. This investigation asks students to work scientifically to measure the effect that exercise has on the heart rate.
Detailed explanation-3: -Additional benefits of exercise: Improves the muscles’ ability to pull oxygen out of the blood, reducing the need for the heart to pump more blood to the muscles. Reduces stress hormones that can put an extra burden on the heart. Works like a beta blocker to slow the heart rate and lower blood pressure.
