Due to age-related changes in the psychobiological state of masters athletes, this brief report aimed to compare training load responses using heart rate (HR) and ratings of perceived exertion (RPE) during standardized training sessions between masters and young cyclists.
Masters (n = 10; 55.6 [5.0] y) and young (n = 8; 25.9 [3.0] y) cyclists performed separate endurance and high-intensity interval training sessions. Endurance intensity was set at 95% of ventilatory threshold 2 for 1 hour. High-intensity interval training consisted of 6 × 30-second intervals at 175% peak power output with 4.5-minute rest between intervals. HR was monitored continuously and RPE collected at standardized time periods during each session. Banister training impulse and summated-HR-zones training loads were also calculated.
Despite a significantly lower mean HR in masters cyclists during endurance (P = .04; d = 1.06 [±0.8], moderate) and high-intensity interval training (P = .01; d = 1.34 [±0.8], large), no significant differences were noted (P > .05) when responses were determined relative to maximum HR or converted to training impulse and summated-HR-zone loads. Furthermore, no interaction or between-group differences were evident for RPE across either session (P > .05).
HR and RPE values were comparable between masters and young cyclists when relative HR responses and HR training load models are used. This finding suggests HR and RPE methods used to monitor or prescribe training load can be used interchangeably between masters and young athletes irrespective of chronological age.
由于大师级运动员的心理生物状态随年龄的变化，本简要报告旨在比较使用心率（HR）和感知用力评分（RPE）在大师级和年轻自行车手之间标准化训练期间的训练负荷反应。
大师级（n=10；55.6[5.0]岁）和年轻（n=8；25.9[3.0]岁）自行车手分别进行耐力和高强度间歇训练。耐力强度设定为通气阈值 2 的 95%，持续 1 小时。高强度间歇训练包括 6 个 30 秒间隔，峰值功率输出的 175%，间隔之间休息 4.5 分钟。HR 连续监测，每个会话的标准化时间间隔收集 RPE。还计算了班纳斯特训练冲动和总和 HR 区训练负荷。
尽管大师级自行车手在耐力（P=0.04；d=1.06[±0.8]，中等）和高强度间歇训练（P=0.01；d=1.34[±0.8]，大）期间的平均 HR 明显较低，但相对于最大 HR 或转换为训练冲动和总和 HR 区负荷时，没有观察到显著差异（P>0.05）。此外，在任何一个会话中，RPE 都没有表现出交互或组间差异（P>0.05）。
当使用相对 HR 反应和 HR 训练负荷模型时，大师级和年轻自行车手的 HR 和 RPE 值是可比的。这一发现表明，HR 和 RPE 方法可用于监测或规定训练负荷，可以在大师级和年轻运动员之间互换使用，而与实际年龄无关。
