目的：本研究调查了年龄和性别差异的心血管适应的标准化/量化的耐力训练计划，包括两个减量期。研究方法：后者是从频谱分析的心电图记录的心率变异性（HRV）在休息组的青年（19-21岁）和中年（40-45岁），混合性别组（6男6女），前和后标准化的训练。所有受试者都是完成相同的12周跑步计划的休闲跑步者。训练前和训练后，在仰卧位休息和次极量骑行期间测量心率变异性。结果：静息时心率均显著降低（2.7 +/- 0.45次（.）min（-1））和次极量运动期间（8.1 +/-0.67 beats（.）min（-1））。训练后，两个年龄组在休息时的总频谱功率增加（560.7 +/- 308.9 ms（2）），高频功率增加（362.3 +/- 405.5 ms（2））。年轻组在训练计划后总功率增加更大（849.0 +/- 308.7 ms（2））。结论：它的结论是，一个精心设计的12周的耐力训练计划将减少年轻人和老年人的静息和次最大心率。耐力训练后所有组的HRV、总功率和高频功率的显著增加表明，HRV测量似乎提供了一种有效的、无创的评估有氧训练对心血管适应性的方法。
Purpose: This research investigated the age and gender differences in cardiovascular adaptation to a standardized/quantified endurance-training program that included two taper periods. Methods: The latter was analyzed from spectral analysis of electrocardiogram records of heart rate variability (HRV) at rest in groups of young (19-21 yr) and middle aged (40-45 yr), mixed gender groups (6 males and 6 females), pre- and poststandardized training. All subjects were recreational runners who completed the same 12-wk running program. Before, and subsequent to training, HRV was measured during supine rest and submaximal cycling. Results: There was a significant decrease in heart rate both at rest (2.7 +/- 0.45 beats(.)min(-1)) and during submaximal exercise (8.1 +/- 0.67 beats(.)min(-1)) in both age groups after training. After training, total spectral power increased (560.7 +/- 308.9 ms(2)), as well as high-frequency power (362.3 +/- 405.5 ms(2)), in both age groups at rest. The young group showed a greater increase in total power (849.0 +/- 308.7 ms(2)) after the training program. Conclusion: It is concluded that a well-designed 12-wk endurance-training program will decrease resting and submaximal heart rate in both younger and older adults. The significant increase in HRV, total power, and high-frequency power in all groups after endurance training indicates that HRV measurement appears to provide an effective, noninvasive assessment of cardiovascular adaptation to aerobic training.
