This study investigated maximal and submaximal performance (power output) and physiological responses (oxygen uptake, heart rate and blood lactate concentration) of eight male rowers to two different incremental tests to exhaustion performed either in a rowing ergometer without (regular) or with the slide, as well as to a 2000 m race simulation, conducted in a randomized order. Peak oxygen uptake ([Formula: see text]O2peak) was statistically higher (3.4%) in the regular test (5.18 ± 0.44 L.min(-1)) compared with the slide condition (5.01 ± 0.37 L.min(-1); P = 0.005). Time for the on-water race simulation was significantly correlated with the slope of the [Formula: see text]O2-power relationship in the slide condition (r = -0.73, P = 0.043) and [Formula: see text]O2peak during the test in the slide condition was correlated to mean [Formula: see text]O2 at the on-water race simulation (r = 0.78; P = 0.024). Thus, the use of the slide is more beneficial than the regular test when evaluating rowers.
本研究调查了八名男性赛艇运动员在两种不同的递增力竭测试中的最大和次最大运动表现(功率输出)以及生理反应(摄氧量、心率和血乳酸浓度)。这两种测试分别是在无滑动装置(常规)或有滑动装置的赛艇测功仪上进行,以及进行一次2000米比赛模拟,测试以随机顺序进行。与有滑动装置的情况(5.01±0.37 L·min⁻¹)相比,常规测试中的峰值摄氧量([公式:见正文]O₂peak)在统计学上更高(3.4%)(5.18±0.44 L·min⁻¹;P = 0.005)。水上比赛模拟的时间与有滑动装置情况下的[公式:见正文]O₂ - 功率关系的斜率显著相关(r = -0.73,P = 0.043),并且有滑动装置情况下测试期间的[公式:见正文]O₂peak与水上比赛模拟时的平均[公式:见正文]O₂相关(r = 0.78;P = 0.024)。因此,在评估赛艇运动员时,使用滑动装置比常规测试更有益。
