(1) Background: Fatigue impacts neuromuscular performance, especially in endurance sports like rowing. The aim is to explore how continuous workload affects explosiveness and fatigue progression. This study examines acute fatigue during repeated race events by assessing vertical jump height, force output, and subjective fatigue over three consecutive days at the 2024 Hungarian National Rowing Championships. (2) Methods: Nine rowers (five women, four men; mean age 20.17 ± 1.73 years) competed in multiple 2000 m races over three days. Lower limb explosiveness was measured via countermovement jump (CMJ) using a Kistler force plate, pre- and post-race. Heart rate data were recorded with Polar Team Pro. Subjective fatigue was assessed using the 'Daily Wellness Questionnaire'. (3) Results: We found a significant difference in the pattern of the medians of the force exerted by males during the jump between the results of the Thursday preliminaries (ThuQ = 13.3) and the second final (ThuF2 = -75.5). Women showed no notable changes. (4) Conclusion: Repeated high-intensity races induce neuromuscular fatigue in men, reflected in reduced explosiveness and increased subjective fatigue. Future research should incorporate biochemical markers to deepen the understanding of fatigue mechanisms.
(1) 背景：疲劳会影响神经肌肉性能，尤其是在赛艇等耐力运动中。目的是探讨持续的工作量如何影响爆发力和疲劳进展。本研究通过在2024年匈牙利全国赛艇锦标赛上连续三天评估垂直跳高度、力量输出和主观疲劳，来研究重复比赛项目中的急性疲劳。(2) 方法：九名赛艇运动员（五名女性，四名男性；平均年龄20.17 ± 1.73岁）在三天内参加了多次2000米比赛。赛前和赛后使用奇石乐测力台通过反向纵跳（CMJ）测量下肢爆发力。心率数据用极地团队专业设备记录。使用“每日健康问卷”评估主观疲劳。(3) 结果：我们发现，男性在周四预赛（ThuQ = 13.3）和第二场决赛（ThuF2 = -75.5）的跳跃过程中所施加力量的中位数模式存在显著差异。女性没有表现出明显变化。(4) 结论：重复的高强度比赛会导致男性神经肌肉疲劳，表现为爆发力下降和主观疲劳增加。未来的研究应纳入生化指标，以加深对疲劳机制的理解。
