摘要

背景：等长最大自发力（IMVF）对个人健康和体能表现至关重要。因此，需要有效可靠的设备来评估等长最大自发力。目的：确定 Valkyria Trainer Balance® 便携式测力平台在等长模式下的有效性和可靠性。方法：58 名身体健康的人员（30 名男性和 28 名女性）参加了研究。采用重复测量设计来比较峰值力的日间测试-重复测试可靠性。通过将峰值力与 ArtOficio® 力平台进行比较，确定了 Valkyria Trainer Balance® 力平台的有效性。分析包括类内相关系数 (ICC)、测量标准误差 (SEM) 和变异系数 (CV)。CV ⩽10%和 ICC ⩾0.80被认为是可接受的可靠性，而 CV ⩽5%和 ICC ⩾0.90被认为是高可靠性。结果：峰值力的 CV 值显示出较高的日间测试-重复测试可靠性（CV = 4.3% 和 ICC = 0.99）。在比较两种测力平台时，两种设备之间的差异为 1.1%。结论：本研究结果表明，Valkyria Trainer Balance® 力平台在评估身体健康者的 IMVF 方面是有效和可靠的。

Validity and reliability of the Valkyria Trainer Balance ® portable force platform in its isometric mode

BACKGROUND: Isometric maximal voluntary force (IMVF) is essential for individuals’ health and physical performance. Therefore, there is a need for valid and reliable devices to assess IMVF. OBJECTIVE: To determine the validity and reliability of the Valkyria Trainer Balance® portable force platformin its isometric mode. METHODS: Fifty-eight physically healthy individuals (30 men and 28 women) participated in the study. A repeated measures design was used to compare the inter-day test-retest reliability of peak force. The validity of the Valkyria Trainer Balance® force platform was determined by comparing the peak force with the ArtOficio® force platform. The analysis consisted of the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and coefficient of variation (CV). A CV ⩽ 10% and ICC ⩾ 0.80 were considered acceptable reliability, while a ⩽ 5% and ICC ⩾ 0.90 were regarded as high reliability. RESULTS: CV the peak force showed high test-retest inter-day reliability (CV = 4.3% and ICC = 0.99). When comparing both force platforms, there was a 1.1% difference between the two devices. CONCLUSIONS: The results of this study demonstrate that the Valkyria Trainer Balance® force platform is valid and reliable for assessing IMVF in physically healthy individuals.

期刊介绍： Isokinetics and Exercise Science (IES) is an international journal devoted to the study of theoretical and applied aspects of human muscle performance. Since isokinetic dynamometry constitutes the major tool in this area, the journal takes a particular interest in exploring the considerable potential of this technology. IES publishes studies associated with the methodology of muscle performance especially with respect to the issues of reproducibility and validity of testing, description of normal and pathological mechanical parameters which are derivable from muscle testing, applications in basic research topics such as motor learning paradigms and electromyography. The journal also publishes studies on applications in clinical settings and technical aspects of the various measurement systems employed in human muscle performance research. The journal welcomes submissions in the form of research papers, reviews, case studies and technical reports from professionals in the fields of sports medicine, orthopaedic and neurological rehabilitation and exercise physiology.
