Maximum heart rate is the age-based heart rate and is calculated by subtracting age from 220. One should aim at a 50 % heart rate zone to work during warm-up. Thus, option C is correct.
The maximum heart rate is the measure of the heart rate that is calculated based on the age of an individual. It is calculated in order to have an effective workout. It is calculated as,
220 - age = beats per minute (bpm)
The range of the maximum heart rate can be used for the exercise as beats per minute of more than 200 can be fatal. It can lead to palpitations, chest pain, etc.
The range of 50-60% is best for the warm-ups as it is a cool-down zone before an intense workout session. This range allows for the strengthening of heart muscles and blood regulation.
Therefore, option C. 50% is the best maximum heart rate for warm-ups.
