This study tested the hypothesis that athletes participating in intermittent sports would exhibit a faster heart rate recovery (HRR) during the initial phase (<30 s) following maximal exercise than athletes participating in continuous endurance sports. Forty-six male athletes were allocated into continuous (CNT, n = 24) or intermittent groups (INT, n = 22), matched for age and aerobic fitness. Athletes performed maximal exercise on a treadmill using the ramp protocol. Immediately upon exercise cessation, subjects were placed supine with continuous measurement of HR during the first minute of recovery. Data were analyzed in 10-s intervals and compared between the groups. Repeated measures ANOVA showed a group x time interaction effects (p <or= 0.01) for HRR expressed in both beats min(-1) and in percentage of peak post-exercise HR (% HR(peak)). The INT group had lower HR than CNT group at 10 s (189 vs. 192 beats min(-1), p = 0.04; and 96.3 vs. 97.9% HR(peak), p = 0.009) and 20 s (184 vs. 188 beats min(-1), p = 0.049; and 93.6 vs. 95.7% HR(peak), p = 0.021) intervals of recovery. The results suggest that athletes engaged in intermittent sports are likely to have faster HRR during the first 20 s after maximal exercise than their counterparts trained for continuous performance.
这项研究检验了这样一个假设，即参加间歇性运动的运动员在最大运动后的最初阶段（<30 秒）心率恢复（HRR）会更快，而参加连续耐力运动的运动员则不然。46 名男性运动员被分配到连续（CNT，n=24）或间歇组（INT，n=22），按年龄和有氧健身水平匹配。运动员在跑步机上使用斜坡方案进行最大运动。运动停止后，受试者立即仰卧，在恢复的第一分钟内连续测量心率。数据以 10 秒为间隔进行分析，并在两组之间进行比较。重复测量方差分析显示，HRR 的组 x 时间交互效应（p<0.01）以每分钟跳动次数（beats min(-1)）和运动后峰值心率的百分比（% HR(peak)）表示。INT 组在 10 秒（189 比 192 beats min(-1)，p=0.04；96.3 比 97.9% HR(peak)，p=0.009）和 20 秒（184 比 188 beats min(-1)，p=0.049；93.6 比 95.7% HR(peak)，p=0.021）恢复间隔的心率低于 CNT 组。结果表明，与连续表现训练的运动员相比，参加间歇性运动的运动员在最大运动后最初 20 秒内心率恢复可能更快。
