This study compares My Jump Lab and VertVision apps for measuring vertical jump height in handball players, assessing their validity and reliability. The research assesses both apps' accuracy, particularly concerning higher jumps, where errors have been noted, aiming to determine the most reliable tool. The goal is to provide a direct comparison between apps, as well as confirm the apps' validity and reliability for handball players.
The present research is a transversal observational study. Twenty-seven amateur athletes performed five jumps on a contact mat with simultaneous recording by a smartphone with a high-speed camera. Pearson's r, ICC, SEM, CV, and Bland-Altman plots were used to evaluate discrepancies and determine accuracy.
Pearson correlation showed strong relationships, with ICC values between 0.993 and 0.998. Both apps overestimated jump height by 1.86% compared to the platform. Bland-Altman plots indicated minimal differences between observers, confirming high validity and reliability for CMJ measurement. Both apps demonstrated very high concurrent validity ( > 0.9) and reliability, with ICC values near 1 and CV below 5%. My Jump Lab exhibited smaller inter-observer differences, indicating greater consistency.
The ease of use, affordability, and portability make both apps valuable for performance monitoring, training, and injury recovery. While both demonstrated good validity and reliability, My Jump Lab proved more consistent in jump comparisons. These tools extend beyond sports, supporting physiotherapy assessments and athletic training across diverse populations.
本研究比较了My Jump Lab和VertVision应用程序在测量手球运动员垂直跳跃高度方面的表现，评估它们的有效性和可靠性。该研究评估了这两款应用程序的准确性，特别是在较高跳跃高度时的准确性，因为此前已注意到在这方面存在误差，旨在确定最可靠的工具。目标是对这两款应用程序进行直接比较，并确认它们对手球运动员的有效性和可靠性。
本研究是一项横向观察性研究。27名业余运动员在接触垫上进行了5次跳跃，同时用配备高速摄像头的智能手机进行记录。使用皮尔逊相关系数、组内相关系数（ICC）、测量标准误（SEM）、变异系数（CV）和布兰德-奥特曼图来评估差异并确定准确性。
皮尔逊相关性显示出很强的关系，ICC值在0.993至0.998之间。与平台相比，两款应用程序都将跳跃高度高估了1.86%。布兰德-奥特曼图表明观察者之间的差异极小，证实了对反向移动跳跃（CMJ）测量具有很高的有效性和可靠性。两款应用程序都显示出非常高的同时效度（>0.9）和可靠性，ICC值接近1，CV低于5%。My Jump Lab在观察者间差异较小，表明一致性更高。
易用性、可承受性和便携性使这两款应用程序在性能监测、训练和损伤恢复方面具有很高价值。虽然两者都表现出良好的有效性和可靠性，但My Jump Lab在跳跃比较中被证明更具一致性。这些工具的应用范围超出了体育领域，为不同人群的物理治疗评估和运动训练提供了支持。
