  1. Endurance exercise training has a minimal effect on resting heart rate : the HERITAGE study.

    Article - En anglais

    This study determined the effects of a 20-wk endurance training program (The HERITAGE Family Study) on resting heart rate (HRrest).

    HRrest was obtained on a sample of 26 men and 21 women during sleep ; during resting metabolic rate and resting blood pressure measurement periods in the early morning following a 12-h fast and 24-h post-exercise ; and at rest prior to a maximal bout of exercise.

    Following training, the subjects exhibited a 16.0 ± 9.4% (mean ± SD) increase in VO2max (P<0.05), but the HRrest for each of the resting conditions was decreased by only 1.9 to 3.4 bpm (P<0.05), or an average across the three conditions of 2.7 bpm.

    In a larger sample of 253 HERITAGE subjects, HRrest obtained only at the time of the resting blood pressure measurement decreased by only 2.6 bpm, while VO2max increased 17.7 ± 10.0%. It is concluded that there is a significant, but small, decrease in resting heart rate as a result of 20 wk of moderate-to high-intensity endurance training ; which suggests a minimal alteration in either, or both, intrinsic heart rate and autonomic control of HRrest.
