Target heart rates are based on percentages of your maximum heart rate and since you max drops with age, the target must also drop since its the same percentage of a lower number. Heart rate is a sympathetic nervous system reaction to exercise and is therefore controlled by the subconscious brain. It drops with age due a complex subconscious process due to the central governor, a theory put forth by exercise scientist Tim Noakes.
220-your age=target heart rate (i think)
Yes... use this "formula" 220-your age = predicted maximum heart rate
(220 + your age) ×.55 = beats per minute
age
For a woman take the #226 and subtract your age. then figure 80% of that for an aerobic target heart rate. subtracting your age from the #226 gives your maximun heart rate when training your target heart rate will depend on what your work out goal is.
Subtracting your age when finding your target heart rate helps determine your maximum heart rate, which is crucial for safe and effective exercise. The formula typically used is 220 minus your age, providing a rough estimate of the highest number of beats your heart can handle during intense activity. This maximum heart rate is then used to calculate target heart rate zones, ensuring you train within a range that promotes cardiovascular fitness while minimizing the risk of overexertion.
220 - age gives you your target heart rate.
