It is not clear whether or not recreational runners can recover aerobic fitness and performance within one week after marathon running. This study aimed to investigate the effects of running a marathon race on aerobic fitness and performance one week later. Eleven recreational runners (six men, five women) completed the race in 3 h 36 min 20 s ± 41 min 34 s (mean ± standard deviation). Before and 7 days after the race, they performed a treadmill running test. Perceived muscle soreness was assessed before the race and for the following 7 days. The magnitude of changes in the treadmill running test was considered for maximal oxygen uptake ([Formula: see text]Omax) (mean difference -1.2 ml/kg/min; ±90% confidence limits 2 ml/kg/min), for %[Formula: see text]Omax at anaerobic threshold (AT) (-0.5; ±4.1%) and RE (0.2; ±3.5 ml/kg/km), and for both velocity at AT and peak (-0.2; ±0.49 km/h and -0.3; ±0.28 km/h). Perceived muscle soreness increased until 3 days after the race, but there were no clear differences between the values before the race and 4-7 days after it. These results show that physiological capacity associated with marathon running performance is recovered within 7 days after a marathon run.
尚不清楚业余跑步者在马拉松赛后一周内是否能够恢复有氧适能和运动表现。本研究旨在调查参加马拉松比赛对一周后的有氧适能和运动表现的影响。11名业余跑步者（6名男性，5名女性）完成比赛的用时为3小时36分20秒±41分34秒（平均值±标准差）。在比赛前和比赛后7天，他们进行了跑步机跑步测试。在比赛前及之后的7天评估肌肉酸痛感。跑步机跑步测试中的变化幅度在最大摄氧量（[公式：见正文]Omax）（平均差值-1.2毫升/千克/分钟；±90%置信区间2毫升/千克/分钟）、无氧阈（AT）时的%[公式：见正文]Omax（-0.5；±4.1%）和相对摄氧量（RE）（0.2；±3.5毫升/千克/千米）方面进行了考量，在AT时的速度和峰值速度方面也进行了考量（-0.2；±0.49千米/小时和-0.3；±0.28千米/小时）。肌肉酸痛感在赛后3天内持续增加，但赛前和赛后4 - 7天的值之间没有明显差异。这些结果表明，与马拉松跑步表现相关的生理能力在马拉松赛后7天内得以恢复。
