The effect of exercise training on heart rate variability (HRV) and improvements in peak oxygen consumption (VO2peak) was examined in sedentary middle-aged men. The HRV and absolute and relative VO2peak of training (n = 19) and control (n = 15) subjects were assessed before and after a 24-session moderate intensity exercise training programme. Results indicated that with exercise training there was a significantly increased absolute and relative VO2peak (P < 0.005) for the training group (12% and 11% respectively) with no increase for the control group. The training group also displayed a significant reduction in resting heart rate; however, HRV remained unchanged. The trained subjects were further categorized into high (n = 5) and low (n = 5) HRV groups and changes in VO2peak were compared. Improvements in both absolute and relative VO2peak were significantly greater (P > 0.005) in the high HRV group (17% and 20% respectively) compared to the low HRV group (6% and 1% respectively). The groups did not differ in mean age, pretraining oxygen consumption, or resting heart rate. These results would seem to suggest that a short aerobic training programme does not alter HRV in middle-aged men. Individual differences in HRV, however, may be associated with VO2peak response to aerobic training.
研究人员对久坐不动的中年男性进行了运动训练对心率变异性（HRV）以及峰值摄氧量（VO2peak）改善情况的影响研究。在一个为期24节的中等强度运动训练项目前后，对训练组（n = 19）和对照组（n = 15）受试者的HRV、绝对和相对VO2peak进行了评估。结果表明，通过运动训练，训练组的绝对和相对VO2peak显著增加（P < 0.005）（分别增加了12%和11%），而对照组没有增加。训练组的静息心率也显著降低；然而，HRV保持不变。将训练后的受试者进一步分为高HRV组（n = 5）和低HRV组（n = 5），并比较VO2peak的变化。与低HRV组（分别为6%和1%）相比，高HRV组的绝对和相对VO2peak改善幅度显著更大（P > 0.005）（分别为17%和20%）。两组在平均年龄、训练前摄氧量或静息心率方面没有差异。这些结果似乎表明，短期有氧训练项目不会改变中年男性的HRV。然而，HRV的个体差异可能与有氧运动训练的VO2peak反应有关。
