PURPOSE
In the HERITAGE Family Study, heart rate (HR) associated with various percentages of maximal oxygen intake (VO2max) was used to prescribe exercise intensity. When fitness improved, HR at the same power output (PO) decreased, and PO was increased to produce the prescribed HR. Although we assumed that subjects were again working at the same %VO2max, there were no studies with a large heterogeneous population to determine whether this was correct.
METHODS
Therefore, 653 subjects with complete data were classified by age, sex, race, initial VO2max, and VO2max response after 20 wk of training.
RESULTS
All groups had a significant increase in VO2max and a significant decrease in HR at the same absolute PO after training but no difference in HR at the same relative intensity.
CONCLUSIONS
Training does not affect HR at a given %VO2max in a heterogeneous population of men and women, blacks and whites aged 17-65 yr with different initial VO2max values and different responses to training.
目的
在“遗传家庭研究”中，与最大摄氧量（VO2max）的不同百分比相关的心率（HR）被用于规定运动强度。当体能改善时，相同功率输出（PO）下的心率会降低，然后增加功率输出以产生规定的心率。尽管我们假设受试者再次以相同的VO2max百分比进行运动，但尚无针对大量异质人群的研究来确定这是否正确。
方法
因此，将653名拥有完整数据的受试者按年龄、性别、种族、初始VO2max以及训练20周后的VO2max反应进行分类。
结果
所有组在训练后，相同绝对功率输出下的VO2max均显著增加，心率显著降低，但相同相对强度下的心率无差异。
结论
对于年龄在17至65岁、初始VO2max值不同且对训练反应不同的男性和女性、黑人和白人组成的异质人群，训练不会影响给定VO2max百分比下的心率。
