Her heart pumped faster more than ever.
- When we are jogging, our muscles need extra oxygen—some three times as much as resting muscles.
- This need means that our heart starts pumping faster.
- The Heart contracts faster and increases blood circulation, resulting in oxygenated blood, reaching the muscles more quickly, which increases the heart rate.
