The purpose of this study was to analyze heart rate variability (HRV) oscillations before and after a marathon which involved trans-meridian air travel and substantial time zone differences in a professional wheelchair athlete with Charcot-Marie-Tooth (CMT) disease. The natural logarithm of the root mean square difference between adjacent normal R-R intervals (Ln rMSSD) was measured daily on the days before, including and following the race. Relative to baseline, small (-3.8 - -4.6%) reductions in LnRMSSD were observed following relocation and on race-day, indicating only minor effects of travel on cardiac-autonomic activity. On the morning following the marathon, a 23.1% reduction in Ln rMSSD was observed, which returned to baseline by 48 h. The race time set by the athlete was the world-leading time in his class. This case study showed that Ln rMSSD responses to marathon in an elite wheelchair athlete with CMT was similar to those previously reported among unrestricted endurance athletes.
本研究旨在分析一位患有遗传性运动感觉神经病（CMT）的职业轮椅运动员在跨子午线航空旅行和巨大时区差异后，马拉松比赛前后的心率变异性（HRV）波动。在比赛前、比赛期间和比赛后，每天测量自然对数的相邻正常 R-R 间期的均方根差的平方根（Ln rMSSD）。与基线相比，重新安置和比赛日之后，LnRMSSD 有小幅度（-3.8 至-4.6%）的降低，表明旅行对心脏自主活动的影响较小。在马拉松比赛后的第二天早上，Ln rMSSD 降低了 23.1%，48 小时后恢复到基线。运动员设定的比赛时间是他所在级别中的世界领先时间。这项案例研究表明，CMT 精英轮椅运动员对马拉松比赛的 Ln rMSSD 反应与之前在不受限制的耐力运动员中报告的反应相似。
