Answer :
Final answer:
The method of subtracting age from 220 provides a practical estimate of maximum heart rate (HR) during exercise. For instance, a 40-year-old's estimated maximum HR is 180 (220 - 40), offering a quick guideline for tailoring workout intensities based on age-related cardiovascular goals.
Explanation:
The method of estimating maximum heart rate (HR) by subtracting the client's age from 220 provides a practical and widely used guideline in the field of exercise physiology. This formula, often referred to as the age-predicted maximum heart rate, serves as a quick and convenient way to approximate the upper limit of heartbeats per minute during exercise. For instance, a 40-year-old individual would calculate their estimated maximum HR as 220 - 40, resulting in 180 beats per minute. Similarly, a 60-year-old person would use the formula to derive an approximate maximum HR of 160 beats per minute. While individual variations exist, this formula offers a general baseline for determining target heart rates during exercise, assisting fitness professionals in tailoring workout intensities to clients' age-related cardiovascular goals.
