1. The heart rate before the workout is approximately 70 beats per minute.
2. The heart rate during the workout increases to about 140 beats per minute.
3. The highest heart rate recorded is approximately 150 beats per minute.
4. The heart rate after the workout gradually decreases back toward the resting rate.
5. The graph shows both the increase in heart rate during exercise and the decrease afterward, indicating the body’s response to physical activity.
6. The heart rate returns to normal approximately 20 minutes after the workout ends.
7. During the second and eighth minutes, the heart rate is increasing as the body responds to the physical exertion of the workout.
8. During the seventeenth and eighteenth minutes, the heart rate is decreasing as the body recovers from the workout.
9. It is important for the heart to increase its rate during exercise because muscles require more oxygen and nutrients; the cardiovascular system delivers these by pumping blood faster.
10. I think running is a better physical shape because it engages multiple muscle groups, improves cardiovascular endurance, and burns more calories compared to walking.
