Answer :
The correct formula to determine the estimated maximum heart rate is c: '220 minus your age'. This standard formula provides an estimate of the maximum number of heartbeats per minute a person can reach based on their age.
The correct formula to determine your estimated maximum heart rate (MHR) is option (a) 220 minus your age. This formula is widely used as a standard to estimate a person's MHR based on their age. To calculate your MHR, you subtract your age from 220. For example, if you are 25 years old, your estimated MHR would be 220 - 25 = 195 beats per minute (bpm). It is important to note that this is an estimation and there can be variances when compared with laboratory tested MHR. It should also be considered that there are alternative formulas, such as 206 – (0.67 x age) and 208 – (0.7 x age), which can be used for a more personalized estimate.
