When the pulse has decreased, the intensity/load received by the body has decreased. This process is known as recovery.

... fter exercising. Exercises performed with triceps with a load of 27.2 kg, rowing 20.4 kg, benchpress 20 kg, and leg press 54 kg with maximum repetitions and four sets—pulse measurement within 20 seconds. The results showed that there was a change in the initial pulse rate. After 48 and in the sixth minute, it becomes 33. Based on this data, it can be seen that there is an acceleration of recovery during the six-minute process, which is quite fast, up to 15 beats per 20 seconds.
