: Jump test assessment is commonly used for physical tests, with different type of devices used for its evaluation. The purpose of the present study was to examine the validity and reliability of a freely accessible mobile application (VertVision, version 2.0.5) for measuring jump performance. With that intent, thirty-eight college age recreationally active subjects underwent test assessment after a specific warm-up, performing countermovement jumps (CMJs) and squat jumps (SJs) on a contact platform while being recorded with a smartphone camera. Jump height was the criterion variable, with the same formula being used for both methods. Data analysis was performed by two experienced observers. The results showed strong correlations with the contact platform (ICC > 0.9) for both jumps. Furthermore, between-observer reliability was also high (ICC > 0.9; CV ≤ 2.19), with lower values for smallest worthwhile change (≤0.23) and typical error of measurement (≤0.14). Estimation error varied when accounting for both observers, with the SJ accounting for bigger differences (4.1-6.03%), when compared to the CMJ (0.73-3.09%). The study suggests that VertVision is a suitable and handy method for evaluating jump performance. However, it presents a slight estimation error when compared to the contact platform.
跳跃测试评估常用于体能测试，评估时会使用不同类型的设备。本研究的目的是检验一款可免费获取的移动应用程序（VertVision，版本2.0.5）在测量跳跃性能方面的有效性和可靠性。为此，38名处于大学年龄、有休闲运动习惯的受试者在进行特定热身运动后接受测试评估，他们在接触式平台上进行反向移动跳跃（CMJ）和深蹲跳跃（SJ），同时用智能手机摄像头进行记录。跳跃高度是标准变量，两种方法使用相同的公式。由两名经验丰富的观察者进行数据分析。结果显示，两种跳跃与接触式平台的相关性都很强（组内相关系数>0.9）。此外，观察者间的可靠性也很高（组内相关系数>0.9；变异系数≤2.19），最小有意义变化值（≤0.23）和测量的典型误差（≤0.14）较低。综合两名观察者来看，估计误差有所不同，与反向移动跳跃（0.73 - 3.09%）相比，深蹲跳跃的差异更大（4.1 - 6.03%）。该研究表明，VertVision是一种评估跳跃性能的合适且便捷的方法。然而，与接触式平台相比，它存在轻微的估计误差。
