摘要

作为许多运动中无氧表现的预测指标,最大糖酵解率(νLamax)是在实验室环境中评估的。然而,基于实验室的测试和特定运动场地设置之间的差异仍不清楚。本研究的目的是比较优秀青年皮划艇运动员的体力测量和水上测试。15名优秀的德国青年皮划艇运动员在丹斯普林特测力仪上进行了15秒全速冲刺,并在水上进行了50米(男子)和40米(女子)全速冲刺。短跑前和短跑后8分钟每分钟取一次毛细血管血样,测定ΔLa(运动后静息血乳酸浓度与运动后峰值血乳酸浓度之差)。采用Tanita BC-601阻抗分析法评估体成分。15秒全速冲刺时的功率输出与无脂质量(r = 0.82)和总乳酸产量(r = 0.86)高度相关。结合这两个参数的多元回归模型将功率输出预测提高到89%。40米和50米水上短跑的速度与0 lamax (r = 0.72)和体脂率(r = -0.62)呈正相关。在测力仪和水上短跑中,ΔLa和νLamax的显著差异是显而易见的。lamax与水上冲刺和测力器冲刺的平均速度和功率输出呈正相关,身体成分显著影响乳酸积累与性能输出之间的关系。此外,性能指标和毛细血管血乳酸测量值不能在测功仪和水中测试之间简单地转换,这表明测功仪得出的值不能可靠地预测水中性能。

Comparison of maximal glycolytic rate from ergometer to on-water sprinting in elite canoe polo players.

Highlights: Maximal glycolytic rate is not transferable between ergometer and on-water settings in canoe players. Calculated glycolytic contribution is highly correlated to power output on the ergometer. νLamax is moderately correlated to on-water performance.
