Resting heart rate
[res-ting hart rayt]
/ˈrɛstɪŋ hɑrt reɪt/
Noun
The number of heartbeats per minute while at complete rest, typically measured after waking up and before engaging in any physical activity.
Resting heart rate (RHR) is the number of heartbeats per minute when at complete rest, indicating cardiovascular efficiency. A lower RHR often signifies better heart health and fitness, as the heart pumps more blood per beat. Regular aerobic exercise can lower RHR over time. For adults, a typical RHR ranges from 60 to 100 beats per minute, with athletes often having RHRs below 60. Monitoring RHR helps runners track fitness progress and detect overtraining or illness. For example, a sudden increase in RHR might suggest the need for rest or recovery.
