To test the utility of HR variability (HRV) in daily exercise prescription in moderately active (approximately two exercises per week) men and women.
A total of 21 men and 32 women were divided into standard training (ST: males = 7 and females = 7), HRV-guided training (HRV-I: males = 7 and females = 7; HRV-II: females = 10), and control (males = 7 and females = 8) groups. The 8-wk aerobic training period included 40-min exercises at moderate and vigorous intensities (70% and 85% of maximal HR). The ST group was instructed to perform two or more sessions at moderate and three or more sessions at vigorous intensity weekly. HRV-I and HRV-II groups trained on the basis of changes in HRV, measured every morning. In the HRV-I group, an increase or no change in HRV resulted in vigorous-intensity training on that day. Moderate-intensity exercise or rest was prescribed if HRV had decreased. The HRV-II group performed a vigorous-intensity exercise only when HRV had increased. Peak oxygen consumption (VO2peak) and maximal workload (Loadmax) were measured by a maximal bicycle ergometer test before and after the intervention.
The changes in VO2peak did not differ between the training groups either in men or in women. In men, the change in Loadmax was higher in the HRV-I group than in the ST group (30 +/- 8 vs 18 +/- 10 W, P = 0.033). In women, no differences were found in the changes in Loadmax between the training groups (18 +/- 10, 15 +/- 11, and 18 +/- 5 W for ST, HRV-I, and HRV-II, respectively). The HRV-II group performed fewer vigorous-intensity exercises than the ST and HRV-I groups (1.8 +/- 0.3 vs 2.8 +/- 0.6 and 3.3 +/- 0.2 times per week, respectively, P < 0.01 for both).
HRV measurements are beneficial in exercise training prescription in moderately active men and women. Women benefit from HRV guidance by achieving significant improvement in fitness with a lower training load.
检验心率变异性（HRV）在适度活跃（每周约进行两次运动）男性和女性日常运动处方中的实用性。
共有 21 名男性和 32 名女性被分为标准训练（ST：男性=7 名，女性=7 名）、心率变异性指导训练（HRV-I：男性=7 名，女性=7 名；HRV-II：女性=10 名）和对照组（男性=7 名，女性=8 名）。8 周的有氧运动期包括以中等和剧烈强度（最大心率的 70%和 85%）进行 40 分钟的运动。ST 组被指示每周进行两次或更多次中等强度运动，三次或更多次剧烈强度运动。HRV-I 和 HRV-II 组根据每天早晨测量的 HRV 变化进行训练。在 HRV-I 组中，如果 HRV 增加或没有变化，则当天进行剧烈强度训练。如果 HRV 下降，则进行中等强度运动或休息。只有当 HRV 增加时，HRV-II 组才进行剧烈强度运动。在干预前后，使用最大自行车测功计测试测量峰值耗氧量（VO2peak）和最大工作量（Loadmax）。
在男性和女性中，训练组之间的 VO2peak 变化没有差异。在男性中，HRV-I 组的 Loadmax 变化高于 ST 组（30±8 比 18±10 W，P=0.033）。在女性中，训练组之间的 Loadmax 变化没有差异（ST、HRV-I 和 HRV-II 组分别为 18±10、15±11 和 18±5 W）。HRV-II 组进行的剧烈强度运动次数少于 ST 和 HRV-I 组（每周分别为 1.8±0.3、2.8±0.6 和 3.3±0.2 次，均 P<0.01）。
心率变异性测量在适度活跃的男性和女性运动训练处方中是有益的。女性通过较低的训练负荷获得更好的健身效果，从而从心率变异性指导中受益。
