The aim of our study is to investigate whether coupling power output (PO) and heart rate (HR) data of semi-professional road cyclists collected in the field is helpful for optimising the training process. Therefore, HR and PO data during all cycling activities were collected from 23 semi-professional road cyclists for 2 years. Weekly cyclist-specific HR response times (recovery, delay and maximal response time) were extracted from models connecting HR and PO. Linear regression was performed between performance, defined as mean PO during a 1- and 10-min indoor time trial (TT) under controlled circumstances, and weekly HR response times. No significant correlations were found between 1-min TT PO and HR response times. In contrast, significant correlations were obtained between 10-min TT PO and recovery time ( = -0.74, < 0.01), maximal response time ( = -0.70, < 0.01) and delay time ( = -0.48, = 0.03). Moreover, linear relationships were found between 10-min TT PO and delay time ( = -0.68, < 0.01) or maximal response times ( = -0.61, = 0.02) within 14 days of the performed lab test. This suggests that HR response times are important physiological characteristics related to 10-min TT PO for cyclists.
我们研究的目的是调查在野外收集的半职业公路自行车运动员的耦合功率输出（PO）和心率（HR）数据是否有助于优化训练过程。因此，在两年时间里从23名半职业公路自行车运动员的所有骑行活动中收集了心率和功率输出数据。从连接心率和功率输出的模型中提取每周特定于骑行者的心率反应时间（恢复时间、延迟时间和最大反应时间）。在性能（定义为在受控环境下1分钟和10分钟室内计时赛（TT）期间的平均功率输出）和每周心率反应时间之间进行线性回归。在1分钟计时赛功率输出和心率反应时间之间未发现显著相关性。相比之下，在10分钟计时赛功率输出与恢复时间（r = -0.74，p < 0.01）、最大反应时间（r = -0.70，p < 0.01）和延迟时间（r = -0.48，p = 0.03）之间获得了显著相关性。此外，在进行实验室测试的14天内，发现10分钟计时赛功率输出与延迟时间（r = -0.68，p < 0.01）或最大反应时间（r = -0.61，p = 0.02）之间存在线性关系。这表明心率反应时间是与自行车运动员10分钟计时赛功率输出相关的重要生理特征。
