These are behind your knees, on the inner side or top of your foot, your groin, neck and temples. Physiologists at Montana State University report resting heart rates of 28 to 40 bpm. Methods and results Six hundred and fifty-three men and women between the age of 55 and 75 years were included in the Copenhagen Holter Study and underwent 48 h ambulatory electrocardiographic ECG monitoring. Aging influences the heart rate of a person. Moreover, the change in RHR is associated with physical activity status, and people with increased level of physical activity during a time period have low RHR , as also observed in our study Table S4. We also found that participants with relatively high RHR and high physical activity at baseline had a VO 2peak that was similar to people with relatively low RHR and no physical activity. When your heart has to work harder to meet the demand for blood and oxygen, it beats faster. However, we found that the association between change in RHR and VO 2peak was not substantially altered after additional controlling of change in physical activity during the follow-up. In this prospective study of men and women, we found that low RHR at baseline was a strong predictor of high VO 2peak 23 years later. Current results are based on data from the second follow-up, which was performed 7 years after study start. Exercise physiologists at Montana State University recommend taking your pulse four hours after work or exercise, two hours after meals and after sitting or reclining for 30 minutes. In Paris Prospective study , mean RHR decreased by 5 bpm in men and 7 bpm in women, over 16 years. Night-time heart rate , Resting heart rate , 24 h heart rate , Mortality , Prognosis Introduction Epidemiological studies have shown that resting heart rate HR is a predictor of all-cause mortality and cardiovascular CV mortality in subjects with as well as without diagnosed CV disease, and the effect is independent of traditional CV risk factors.
