摘要

本研究有两个主要目标:(i) 评估使用 "我的跳跃实验室"(MJL)移动应用程序实时测量逆向移动跳跃(CMJ)高度与测力板测量的并发有效性和一致性;(ii) 评估测力板和 MJL 应用程序的会内可靠性和一致性。这项横断面调查涉及 36 名参加娱乐活动的健康男性(平均年龄 = 22.2 ± 2.9 岁),他们在测力板上重复进行了五次 CMJ,休息时间为 2 分钟。同时使用测力板和 MJL 应用程序记录他们的跳跃高度。在所有情况下,两种方法的类内相关系数均为 0.984,具有很高的有效性。测力板和 MJL 应用之间几乎完全相关(r = 0.968,p = 0.001,在所有情况下),一致性非常好,平均差异为 1.016 厘米(95% 置信区间:-1.229 至 -0.803 厘米)。在测力平台(SEM,0.42 厘米;CV,1.21%;MDC,1.5;SWC,1.12)和 MJL(SEM,0.43 厘米;CV,1.23%;MDC,1.20;SWC,1.17)中观察到了较高的时段内可靠性。结果表明,MJL 应用程序是实时测量跳跃成绩和评估 CMJ 高度的有效而可靠的工具。

The concurrent validity and reliability of the My Jump Lab smartphone app for the real-time measurement of vertical jump performance
The present study had two main objectives: (i) to assess the concurrent validity and agreement of real-time measurement of counter-movement jump (CMJ) height using the My Jump Lab (MJL) mobile application in comparison to a force plate and (ii) to evaluate the intra-session reliability and agreement of the force plate and the MJL application. This cross-sectional investigation involved 36 recreationally active, healthy men (mean age = 22.2 ± 2.9 years) who performed five CMJ repetitions on the force plate with a 2-min rest period. Their jump heights were concurrently recorded using both the force plate and the MJL application. The high validity between the two methods intraclass correlation coefficient >0.984) was observed for all cases. There was a nearly perfect correlation ( r = 0.968, p = 0.001, in all cases) between the force plate and MJL application, with very good agreement and a mean difference of 1.016 cm (95% confidence interval: −1.229 to −0.803 cm). High intra-session reliability was observed in the force platform (SEM, 0.42 cm; CV, 1.21%; MDC, 1.5; SWC, 1.12), and MJL (SEM, 0.43 cm; CV, 1.23%; MDC, 1.20; SWC, 1.17). The results demonstrate that the MJL application is a valid and reliable tool for measuring jump performance in real-time and assessing CMJ height.
