Answer:
Your target heart rate (THR) is the range of heartbeats per minute you should aim for during exercise in order to achieve optimal cardiorespiratory endurance. The THR is typically between 50% to 85% of your maximum heart rate, which is calculated as 220 minus your age.
The level of intensity of exercise you perform is directly related to your THR. When you exercise within your THR, your body is working at an intensity level that is optimal for improving your cardiorespiratory endurance. At this intensity, your body is able to take in enough oxygen to supply your muscles with the energy they need to sustain the activity for a longer period of time.
If you exercise below your THR, you may not be working hard enough to improve your cardiorespiratory endurance, and you may not see the desired improvements in your fitness level. Conversely, if you exercise above your THR, you may be working too hard, which can lead to fatigue, injury, and other negative effects.
Therefore, it is important to monitor your heart rate during exercise and adjust the intensity level accordingly to stay within your target heart rate range. This can help ensure that you are working at an appropriate level to improve your cardiorespiratory endurance while avoiding potential negative effects of overexertion.
