To investigate how resistance training (RT) in a regular training program affects neuromuscular fatigue (NMF) and gross efficiency (EGROSS) in elite rowers.
Twenty-six elite male rowers performed 4 RT sessions within 10 days. At baseline and after the first and fourth RT, EGROSS and NMF were established. From breathing gas, EGROSS was determined during submaximal rowing tests. Using a countermovement jump test, NMF was assessed by jump height, flight time, flight-to-contraction-time ratio, peak power, and time to peak power. Muscle soreness was assessed using a 10-cm-long visual analog scale.
No significant differences were found for EGROSS (P = .565, ω2 = .032). Muscle soreness (P = .00, ω2 = .500) and time to peak power (P = .08, ω2 = 0.238) were higher compared with baseline at all test moments. Flight-to-contraction-time ratio, jump height, and peak power after the fourth RT differed from baseline (P < .05, ω2 = .36, ω2 = .38, and ω2 = .31) and from results obtained after the first RT (P < .05, ω2 = .36, ω2 = .47, and ω2 = .22).
RT in general does not influence EGROSS, but large individual differences (4.1%-14.8%) were observed. NMF is affected by RT, particularly after multiple sessions. During periods of intensified RT, imposed external load for low-intensity endurance training need not be altered, but rowers are recommended to abstain from intensive endurance training. Individual monitoring is strongly recommended.
研究常规训练方案中的抗阻训练（RT）如何影响精英赛艇运动员的神经肌肉疲劳（NMF）和总效率（EGROSS）。
26 名精英男性赛艇运动员在 10 天内进行了 4 次 RT 训练。在基线以及第一次和第四次 RT 后，确定了 EGROSS 和 NMF。通过呼吸气体，在次最大划桨测试中确定 EGROSS。使用反跳测试，通过跳跃高度、腾空时间、腾空与收缩时间比、峰值功率和达到峰值功率的时间来评估 NMF。肌肉酸痛使用 10cm 长的视觉模拟量表进行评估。
EGROSS 没有显著差异（P =.565，ω2 =.032）。与基线相比，所有测试时刻的肌肉酸痛（P =.00，ω2 =.500）和达到峰值功率的时间（P =.08，ω2 = 0.238）更高。第四次 RT 后的腾空与收缩时间比、跳跃高度和峰值功率与基线不同（P <.05，ω2 =.36，ω2 =.38，ω2 =.31），也与第一次 RT 后的结果不同（P <.05，ω2 =.36，ω2 =.47，ω2 =.22）。
一般来说，RT 不会影响 EGROSS，但观察到较大的个体差异（4.1%-14.8%）。NMF 受到 RT 的影响，特别是在多次训练后。在强化 RT 期间，不必改变低强度耐力训练的外部负荷，但建议运动员避免高强度耐力训练。强烈建议进行个体监测。
