This study explores whether an on-water kayak-specific resistance exercise (KSRE) performed during the warm-up period can induce postactivation potentiation (PAP) to improve subsequent kayak-sprint performance. The KSRE involves stringing several tennis balls around the boat’s hull to induce drag while paddling. In a laboratory setting, 10 well-trained male ([Formula: see text]) and female ([Formula: see text]) kayakers performed three repetitions of the single-arm seated-row (SASR) at 91% one-repetition maximum to induce PAP and were assessed for their peak power output while performing SASR on the Keiser machine at two-minute intervals up to 16 min. Each individual’s latency period for the onset of PAP during this exercise was recorded. In separate sessions, athletes performed in random, a 30 m kayak-sprint in a swimming pool setting after either control (no pre-performance loading) or experimental (post-PAP induction via the KSRE taking into account the individual’ onset of PAP latencies period obtained in the laboratory) conditions. Criterion measures of boat velocities of the third and fourth stroke from the start and 30 m sprint times, assessed using video, were not significantly different between control and experimental conditions. The translation of increased power output elicited via PAP using land-based resistance exercises into water-based resistance exercises to improve kayak-sprint performance remains a challenge.

尝试使用水上皮划艇专用热身来诱导激活后增强以提高皮划艇冲刺性能

本研究探讨了在热身期间进行的水上皮划艇特定阻力运动 (KSRE) 是否可以诱导激活后增强 (PAP) 以改善随后的皮划艇冲刺表现。KSRE 包括在船体周围串几个网球，以在划桨时产生阻力。在实验室环境中，10 名训练有素的男性（[公式：见文本]）和女性（[公式：见文本]）皮划艇运动员以 91% 的最大重复次数进行了 3 次单臂坐式划船 (SASR)诱导 PAP 并评估其峰值功率输出，同时以两分钟的间隔在 Keizer 机器上执行 SASR，最多 16 分钟。记录每个人在此练习期间 PAP 发作的潜伏期。在不同的阶段，运动员随机表演，在控制（无预性能负荷）或实验（通过 KSRE 进行 PAP 诱导后，考虑到在实验室中获得的个体 PAP 潜伏期开始）条件后，在游泳池环境中进行 30 m 皮划艇冲刺。从开始和 30 m 冲刺时间开始的第三和第四冲程的船速度的标准测量，使用视频评估，在控制和实验条件之间没有显着差异。将通过 PAP 产生的增加的功率输出转化为使用陆基阻力练习到水基阻力练习以提高皮划艇冲刺性能仍然是一个挑战。从开始和 30 m 冲刺时间开始的第三和第四冲程的船速度的标准测量，使用视频评估，在控制和实验条件之间没有显着差异。将通过 PAP 产生的增加的功率输出转化为使用陆基阻力练习到水基阻力练习以提高皮划艇冲刺性能仍然是一个挑战。从开始和 30 m 冲刺时间开始的第三和第四冲程的船速度的标准测量，使用视频评估，在控制和实验条件之间没有显着差异。将通过 PAP 产生的增加的功率输出转化为使用陆基阻力练习到水基阻力练习以提高皮划艇冲刺性能仍然是一个挑战。
