This study assessed the longer-term (12-month) variability in post-exercise heart rate recovery following a submaximal exercise test. Longitudinal data was analysed for 97 healthy middle-aged adults (74 male, 23 female) from 2 occasions, 12 months apart. Participants were retrospectively selected if they had stable physical activity habits, submaximal treadmill fitness and anthropometric measurements between the 2 assessment visits. A submaximal Bruce treadmill test was performed to at least 85% age-predicted maximum heart rate. Absolute heart rate and Δ heart rate recovery (change from peak exercise heart rate) were recorded for 1 and 2 min post-exercise in an immediate supine position. Heart rate recovery at both time-points was shown to be reliable with intra-class correlation coefficient values ≥ 0.714. Absolute heart rate 1-min post-exercise showed the strongest agreement between repeat tests (r = 0.867, P < 0.001). Lower coefficient of variation (≤ 10.2%) and narrower limits of agreement were found for actual heart rate values rather than Δ heart rate recovery, and for 1-min rather than 2-min post-exercise recovery time points. Log-transformed values generated better variability with acceptable coefficient of variation for all measures (2.2-10%). Overall, 1 min post-exercise heart rate recovery data had least variability over the 12-month period in apparently healthy middle-aged adults.
本研究评估了亚极量运动试验后心率恢复的更长时间（12 个月）变异性。对 97 名健康中年成年人（74 名男性，23 名女性）在 2 次间隔 12 个月的随访中进行了纵向数据分析。如果参与者在 2 次评估访视之间具有稳定的体力活动习惯、亚极量跑步机健身和人体测量测量，则回顾性选择他们。进行亚极量布鲁斯跑步机测试，直至达到 85%的年龄预测最大心率。在立即仰卧位时，记录运动后 1 分钟和 2 分钟的绝对心率和 Δ心率恢复（从运动峰值心率的变化）。心率恢复在两个时间点均具有可靠的内部一致性系数值≥0.714。绝对心率在运动后 1 分钟的测试之间显示出最强的一致性（r = 0.867，P <0.001）。实际心率值而不是 Δ心率恢复以及运动后 1 分钟而不是 2 分钟的恢复时间点的变异系数（≤10.2%）和一致性界限更窄。对于所有测量值（2.2-10%），对数转换值产生了更好的可变性和可接受的变异系数。总体而言，在明显健康的中年成年人中，运动后 1 分钟的心率恢复数据在 12 个月内的变异性最小。
