Abstract

Force-velocity (FV) relationships are used to evaluate athletes and individualise training in several tasks. In rowing, only one previous study has determined FV relationships using ergometers. This study aimed to develop a method to obtain FV relationships during on-water rowing, to assess their quality and inter-day reliability and to compare them with ergometer profiles. Fourteen participants performed 8 all-out starts in instrumented double scull boats with 3 scull lengths under two conditions: two active rowers or one active and one passive rower. The FV relationships, reconstructed with all the conditions, were linear with a high goodness of fit (median R2: 0.96), covering 24.6 ± 5.0% of the velocity range. Ninety-five per cent confidence intervals for maximal force (F0: 3.9 ± 0.5%) and maximal velocity (V0: 6.2 ± 1.5%) were relatively narrow. The coefficient of variation for inter-day reliability was below 10% and intraclass correlation ranging from 0.69 for V0 to 0.96 for F0. Correlations between on-water and ergometer rowing were significant for F0 (r = 0.70) and Pmax (r = 0.82) but not for V0 (r = 0.11). F0 and V0 were significantly higher (23%) and lower (31%) on the ergometer, respectively. These results highlight a reliable linear FV relationship during on-water rowing to characterise rowing force production capacities, largely affected by on-water technical skills.

水上划艇的力-速度和功率-速度关系。
力-速度(FV)关系是用来评估运动员和个性化训练的几个任务。在赛艇中,只有一项先前的研究使用测力计确定了FV关系。本研究旨在开发一种方法来获取水上划船期间的FV关系,评估其质量和日间可靠性,并将其与测功仪数据进行比较。14名参赛者在两种情况下,分别由两名主动桨手或一名主动桨手和一名被动桨手,在三种桨长的双桨船上进行8次全力以赴的起跑。在所有条件下重建的FV关系均为线性关系,拟合度较高(中位R2: 0.96),覆盖24.6±5.0%的速度范围。最大力(F0: 3.9±0.5%)和最大速度(V0: 6.2±1.5%)的95%置信区间相对较窄。日间信度变异系数小于10%,类内相关系数为0.69 ~ 0.96。水上划船和测力仪划船之间的相关性在F0 (r = 0.70)和Pmax (r = 0.82)上显著,但在V0 (r = 0.11)上不显著。在测力仪上,F0和V0分别显著较高(23%)和较低(31%)。这些结果强调了在水上划船过程中可靠的线性FV关系,以表征划船力的生产能力,很大程度上受水上技术技能的影响。

期刊介绍: Sports Biomechanics is the Thomson Reuters listed scientific journal of the International Society of Biomechanics in Sports (ISBS). The journal sets out to generate knowledge to improve human performance and reduce the incidence of injury, and to communicate this knowledge to scientists, coaches, clinicians, teachers, and participants. The target performance realms include not only the conventional areas of sports and exercise, but also fundamental motor skills and other highly specialized human movements such as dance (both sport and artistic). Sports Biomechanics is unique in its emphasis on a broad biomechanical spectrum of human performance including, but not limited to, technique, skill acquisition, training, strength and conditioning, exercise, coaching, teaching, equipment, modeling and simulation, measurement, and injury prevention and rehabilitation. As well as maintaining scientific rigour, there is a strong editorial emphasis on ''reader friendliness''. By emphasising the practical implications and applications of research, the journal seeks to benefit practitioners directly. Sports Biomechanics publishes papers in four sections: Original Research, Reviews, Teaching, and Methods and Theoretical Perspectives.
