is the training heart rate index that allows for improvement in aerobic capacity with training since submaximal heart rate will change with conditioning.

a lot ig i am not sure

the more fit you are, the faster the recovery. your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute—a drop of less than 12 beats a minute is considered abnormal. this “recovery heart rate” is measured as part of an exercise stress test.
