(1) Background: Exercise that exceeds the body's accustomed load can lead to oxidative stress and increased fatigue during intense training or competition, resulting in decreased athletic performance and an increased risk of injury, and the new medicinal H may be beneficial as an antioxidant. Therefore, we explored the effect of short-term supplementation of hydrogen-rich water (HRW) on the work performance and fatigue recovery of dragon boat athletes after training. (2) Methods: Eighteen dragon boat athletes who trained for 4 h a day (2 h in the morning and 2 h in the afternoon) were divided into an HRW group (n = 9) and a placebo water (PW) group (n = 9), drinking HRW or PW for 7 days. Each participant completed 30 s rowing dynamometer tests, monitoring the heart rate at baseline (i.e., Day 1) and after the intervention (on Day 8). (3) Result: Drinking HRW increased the maximum power and average power of the 30 s rowing test and decreased the maximum heart rate during the period. After the rowing test, the HRW group's heart rate dropped significantly after 2 min of recovery, while the PW group's heart rate did not drop. There was no significant difference between the 30 s rowing distance and the predicted duration of rowing 500 m. (4) Conclusions: Drinking HRW in the short term can effectively improve the power performance of dragon boat athletes and is conducive to the recovery of the heart rate after exercise, indicating that HRW may be a suitable means of hydration for athletes.
（1）背景：超过身体习惯负荷的运动可能会导致氧化应激和剧烈训练或比赛期间的疲劳增加，从而降低运动表现并增加受伤风险，而新型药物 H 可能作为一种抗氧化剂有益。因此，我们探讨了短期补充富氢水（HRW）对龙舟运动员训练后工作表现和疲劳恢复的影响。（2）方法：18 名每天训练 4 小时（上午 2 小时，下午 2 小时）的龙舟运动员分为富氢水组（n = 9）和安慰剂水（PW）组（n = 9），连续 7 天分别饮用 HRW 或 PW。每位参与者完成 30 秒划船测力计测试，在基线（即第 1 天）和干预后（第 8 天）监测心率。（3）结果：饮用 HRW 提高了 30 秒划船测试的最大功率和平均功率，降低了期间的最大心率。在划船测试后，HRW 组在 2 分钟的恢复后心率明显下降，而 PW 组的心率没有下降。30 秒划船距离与预计划 500 米的时间之间没有显著差异。（4）结论：短期饮用 HRW 可有效提高龙舟运动员的功率表现，有利于运动后心率的恢复，表明 HRW 可能是运动员合适的补水方式。
