Background
The heights obtained during the countermovement jump and drop jump tests have been measured by numerous studies using different calculation methods and pieces of equipment. However, the differences in calculation methods and equipment used have resulted in discrepancies in jump height being reported.
Objectives
The aim of this systematic review was to examine the available literature pertaining to the different calculation methods to estimate the jump height during the countermovement jump and drop jump.
Methods
A systematic review of the literature was undertaken using the SPORTDiscus, MEDLINE, CINAHL, and PubMed electronic databases, with all articles required to meet specified criteria based on a quality scoring system.
Results
Twenty-one articles met the inclusion criteria, relating various calculation methods and equipment employed when measuring jump height in either of these two tests. The flight time and jump-and-reach methods provide practitioners with jump height data in the shortest time, but their accuracy is affected by factors such as participant conditions or equipment sensitivity. The motion capture systems and the double integration method measure the jump height from the centre of mass height at the initial flat foot standing to the apex of jumping, where the centre of mass displacement generated by the ankle plantarflexion is known. The impulse-momentum and flight time methods could only measure the jump height from the centre of mass height at the instant of take-off to the apex of jumping, thus, providing statistically significantly lower jump height values compared with the former two methods. However, further research is warranted to investigate the reliability of each calculation method when using different equipment settings.
Conclusions
Our findings indicate that using the impulse-momentum method via a force platform is the most appropriate way for the jump height from the instant of take-off to the apex of jumping to be measured. Alternatively, the double integration method via a force platform is preferred to quantify the jump height from the initial flat foot standing to the apex of jumping.

反向运动和落跳试验中测量跳跃高度的不同计算方法的系统回顾
背景
反向运动跳跃和下落跳跃测试中获得的高度已经通过使用不同计算方法和设备的大量研究进行了测量。然而,计算方法和所用设备的差异导致报告的跳跃高度存在差异。
目标
本系统评价的目的是检查有关不同计算方法的可用文献,以估计反向运动跳跃和下降跳跃期间的跳跃高度。
方法
使用 SPORTDiscus、MEDLINE、CINAHL 和 PubMed 电子数据库对文献进行了系统回顾,所有文章都需要满足基于质量评分系统的特定标准。
结果
21 篇文章符合纳入标准,涉及在这两个测试中测量跳跃高度时使用的各种计算方法和设备。飞行时间和跳跃距离法在最短时间内为练习者提供跳跃高度数据,但其准确性受参与者条件或设备灵敏度等因素的影响。运动捕捉系统和双积分方法测量从初始平足站立时的质心高度到跳跃顶点的跳跃高度,其中由脚踝跖屈产生的质心位移是已知的。冲量法和飞行时间法只能测量起跳瞬间质心高度到跳跃顶点的跳跃高度,因此,与前两种方法相比,提供统计上显着降低的跳跃高度值。然而,需要进一步研究以调查使用不同设备设置时每种计算方法的可靠性。
结论
我们的研究结果表明,通过力平台使用脉冲动量法是测量从起跳瞬间到跳跃顶点的跳跃高度的最合适方法。或者,首选通过力平台的双积分方法来量化从初始平脚站立到跳跃顶点的跳跃高度。
