The vertical jump can be analyzed based on the flight time achieved by the individual. This measurement can be obtained using a force platform or a three-dimensional infrared camera system, but such equipment is expensive and requires training for data collection and processing. Thus, this study aimed to evaluate the accuracy and reliability of using a smartphone and the Kinovea software compared with a force platform as a method of vertical jump analysis.
For this purpose, two independent evaluators analyzed videos of bipodal and unipodal vertical jumps by counting the variables among participants. The participants performed three consecutive jumps in bipodal and unipodal conditions with the dominant and non-dominant legs.
The intra-rater analysis for bipodal jumps was found to have excellent reproducibility (ICC = 0.903 to 0.934), whereas for unipodal jumps, the reproducibility was moderate to excellent (ICC = 0.713 to 0.902). The inter-rater analysis showed that for bipodal jumps, the reproducibility is substantial to excellent (ICC = 0.823 to 0.926), while for unipodal jumps, it is moderate (ICC = 0.554 to 0.702).
Therefore, it can be concluded that the vertical jump evaluation can be performed using the smartphone-Kinovea system. However, the same evaluator should carry out the evaluation to maintain reliable indices.
垂直跳跃可根据个人达到的飞行时间进行分析。此测量可使用力平台或三维红外摄像系统获得，但此类设备价格昂贵，且需要进行数据收集和处理方面的培训。因此，本研究旨在评估使用智能手机和Kinovea软件与力平台相比作为垂直跳跃分析方法的准确性和可靠性。
为此，两名独立评估者通过计算参与者之间的变量来分析双脚和单脚垂直跳跃的视频。参与者在双脚和单脚条件下用优势腿和非优势腿连续进行三次跳跃。
发现双脚跳跃的评估者内分析具有出色的可重复性（ICC = 0.903至0.934），而单脚跳跃的可重复性为中等至出色（ICC = 0.713至0.902）。评估者间分析表明，双脚跳跃的可重复性为实质性至出色（ICC = 0.823至0.926），而单脚跳跃的可重复性为中等（ICC = 0.554至0.702）。
因此，可以得出结论，垂直跳跃评估可使用智能手机 - Kinovea系统进行。然而，应由同一名评估者进行评估以维持可靠的指标。
