Abstract

Aims

This study evaluated the validity and reliability of the GoJump system, a photoelectric cell-based device, for estimating vertical jump height.

Methods

A total of 100 counter movement jumps (CMJs) were performed by 20 healthy adults, with measurements taken using both the GoJump system and a force platform.

Results

The results showed high consistency between the two devices (ICC = 0.999, P < 0.001), with the GoJump system slightly underestimating jump height compared to the force platform. The GoJump system demonstrated high validity and retest reliability, making it a practical tool for effective and economical jump training monitoring.

Objectifs

Cette étude a évalué la validité et la fiabilité du système GoJump, un dispositif à base de cellules photoélectriques destiné à estimer la hauteur de sauts verticaux.

Méthodes

Un total de 100 sauts en contre-mouvement (CMJ) a été effectué par 20 adultes en bonne santé, les mesures étant prises à la fois avec le système GoJump et une plate-forme de force (méthode de mesure de référence).

Résultats

Les résultats ont montré une grande cohérence entre les deux appareils (ICC = 0,999, p < 0,001), le système GoJump sous-estimant légèrement la hauteur du saut par rapport à la plate-forme de force. Le système GoJump a démontré une validité et une fiabilité de retest élevées, ce qui en fait un outil pratique pour un suivi efficace et économique des performances en sauts verticaux.

GoJump光电池估算垂直跳跃高度的有效性和可靠性

本研究评估了GoJump系统（一种基于光电池的设备）用于估计垂直跳跃高度的有效性和可靠性。方法20例健康成人共进行100次反动作跳跃（CMJs），采用GoJump系统和力平台进行测量。结果两种仪器检测结果一致性高(ICC = 0.999, P <；0.001)，与力平台相比，GoJump系统略微低估了跳跃高度。GoJump系统具有较高的效度和重测信度，是一种经济有效的跳跃训练监测工具。摘要目的：利用光电子交换技术，将光电子交换技术应用到光电子交换系统中，使光电子交换技术应用于光电子交换系统。总共有100个成功的成年（CMJ）和20个成功的成年（bonne - santest）的成年（sst - santest）的成年（sst - santest）的成年（sst - santest）的成年（sst - santest）的成年（sst - santest）的成年（sst - santest）的成年（sst - santest）。rs - sys - sys - sys - sys - sys - sys - sys - sys - sys - sys - sys - sys - sys (ICC = 0,999, p <；2001), le system system system GoJump - sestiment system system system system system system system system system system system system system system。system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system - system
