Question

Ou have a 44-year old male client with a resting heart rate of 68 bpm. if using the heart rate reserve method (karvonen formula), what would be his optimal training intensity range for aerobic exercise aimed at cardiorespiratory improvements?

Answer 1

The intensity range would be 60-80%.

A high resting heart rate is indicative of an inefficient heart or possible arrhythmia. Physical activity assessments should begin after the client has been screened and resting measurements have been assessed.  Moderate intensity exercise uses energy 3 - 6 times that of resting metabolism, which equates to 3 -6 METs.
