Explanation:
1. my pulse is still normal before I do the activity but when I exercised it accelerated.
2. Yes, because before doing jumping my pulse rate is 60-100 beats but after jumping my pulse rate is 75-128. because jumping can make your heart starts pumping faster, your muscles need extra oxygen.
3. it helps your heart muscle become more efficient and better able to pump blood throughout your body. This means that the heart pushes out more blood with each beat, allowing it to beat slower and keep your blood pressure under control.
