Vertical jumps can be used to assess neuromuscular status in sports performance. This is particularly important in Cerebral Palsy Football (CP Football) because players are exposed to high injury risk, but it may be complicated because the gold standard for assessing jump performance is scarce in field evaluation. Thus, field techniques, such as mobile apps, have been proposed as an alternative method for solving this problem.
This study aims to evaluate the reliability of the measures of the MyJump2 app to assess vertical jump performance in professional CP Football.
We assessed 40 male CP Football athletes (age 28.1 [SD 1.4] years, weight 72.5 [SD 6.2] kg, and height 176 [SD 4.2] cm) through the countermovement jump (CMJ) and squat jump (SJ) using a contact mat. At the same time, we assessed the athletes using the MyJump2 app.
There were no significant differences between the instruments in SJ height (P=.12) and flight time (P=.15). Additionally, there were no significant differences between the instruments for CMJ in jump height (P=.16) and flight time (P=.13). In addition, it was observed that there were significant and strong intraclass correlations in all SJ variables varying from 0.86 to 0.89 (both P<.001), which was classified as "almost perfect." Similar results were observed in all variables from the CMJ, varying from 0.92 to 0.96 (both P ≤.001).
We conclude that the MyJump2 app presents high validity and reliability for measuring jump height and flight time of the SJ and CMJ in CP Football athletes.
垂直跳跃可用于评估运动表现中的神经肌肉状态。在脑瘫足球（CP 足球）中，这一点尤为重要，因为球员面临着高受伤风险，但由于评估跳跃表现的金标准在现场评估中稀缺，因此可能会变得复杂。因此，已经提出了诸如移动应用程序之类的现场技术作为解决此问题的替代方法。
本研究旨在评估 MyJump2 应用程序评估专业 CP 足球中垂直跳跃表现的测量值的可靠性。
我们使用接触垫通过反向跳跃（CMJ）和深蹲跳跃（SJ）评估了 40 名男性 CP 足球运动员（年龄 28.1 [SD 1.4] 岁，体重 72.5 [SD 6.2] 公斤，身高 176 [SD 4.2] 厘米）。同时，我们使用 MyJump2 应用程序评估了运动员。
SJ 高度（P=.12）和飞行时间（P=.15）在仪器之间没有显着差异。此外，CMJ 中跳跃高度（P=.16）和飞行时间（P=.13）的仪器之间也没有显着差异。此外，观察到 SJ 所有变量的组内相关性均具有显著的强相关性，范围从 0.86 到 0.89（均 P<.001），被归类为“几乎完美”。CMJ 的所有变量也观察到了相似的结果，范围从 0.92 到 0.96（均 P ≤.001）。
我们得出的结论是，MyJump2 应用程序在测量 CP 足球运动员 SJ 和 CMJ 的跳跃高度和飞行时间方面具有很高的有效性和可靠性。
