Abstract

This study assessed the validity of the Entralpi force plate in the assessment of finger flexor performance in rock climbers. In addition to a static force evaluation, peak force, peak impulse, and total impulse were measured during 30 all-out performance trials by 15 participants, in which force during the trials was recorded simultaneously by the Entralpi and a Pasco force plate. Agreement between devices was assessed by a variety of statistical analyses, including intraclass correlation coefficient (ICC), coefficient of variation (CV), and Bland-Altman analyses. The static force evaluation showed a mean relative error of 0.41% and excellent day-to-day reliability (ICC = 1; CV = 0.03%). Peak force, peak impulse, and total impulse from the performance trials demonstrated strong agreement (ICC ≥ 0.991, CV ≤ 1.9%, Bland-Altman mean bias ≤ 0.5%). These results illustrate that the Entralpi force plate provides accurate and reliable data for rock climbing related tasks at an affordable cost.

Entralpi力板在评估攀岩者手指屈肌表现指标中的有效性。

本研究评估Entralpi力板在评估攀岩者手指屈肌表现的有效性。除了静力评估外，15名参与者在30次全力以赴的表现试验中测量了峰值力、峰值冲量和总冲量，其中试验期间的力由Entralpi和Pasco力板同时记录。通过各种统计分析评估设备之间的一致性，包括类内相关系数(ICC)、变异系数(CV)和Bland-Altman分析。静力评估的平均相对误差为0.41%，具有良好的日常可靠性(ICC = 1;cv = 0.03%)。性能试验的峰值力、峰值冲量和总冲量表现出很强的一致性(ICC≥0.991,CV≤1.9%，Bland-Altman平均偏差≤0.5%)。这些结果说明Entralpi测力板以合理的成本为攀岩相关任务提供了准确可靠的数据。

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.
