Subtracting age from 210

Subtracting age from 230

The correct answer is: Subtracting age from 220

Maximal heart rate is generally estimated using the commonly accepted formula of subtracting age from 220. This formula was developed through research and provides a simple way to gauge an individual's peak heart rate during intense aerobic exercise. The concept behind this calculation is that as a person ages, their maximum heart rate naturally declines. Thus, by taking the maximum possible heart rate of 220 and adjusting it based on age, one can estimate an appropriate target heart rate for exercise intensity. The formula aids fitness professionals in designing tailored cardiovascular workout programs that can help clients achieve their fitness goals while ensuring safety. It serves as a guideline, acknowledging that individual variations can occur due to fitness levels, health conditions, and genetics. This approach helps in determining training zones and ensuring that clients work effectively within their physiological limits.
