摘要

本研究的目的是:(a) 评估足球专项最大垂直弹跳(定向测试,HT)的场内可靠性和实用性;(b) 与黄金标准仪器(三维运动捕捉系统,MOCAP)相比,分析易于使用且成本效益高的仪器(智能手机摄像头,MOB)在获取 HT 过程中垂直弹跳表现的有效性。12 名半职业高水平足球运动员和 15 名业余足球男运动员(23.9 ± 3.6 岁)进行了三次立定跳远尝试,并使用 MOB 和 MOCAP 记录了运动学数据。采用类内相关系数(ICC)和变异系数(CV)来衡量训练期间的可靠性。采用科恩效应大小(ES)的 T 检验、皮尔逊乘积矩和 Bland-Altman 分析来获得 MOB 的有效性。关于会话内信度,CV 为 1.13%,ICC 为 0.98,可以接受。尊重效度标准并未发现显著差异(p 微不足道),"几乎完美 "的相关性(Pearson)(r = 0.98;p = 0.99)。

Reliability and usefulness of maximum soccer-specific jump test: a valid and cost-effective system to measure on soccer field.

The aims of this study were (a) to assess intra-session reliability and usefulness of the soccer-specific maximum vertical jump (heading test, HT) and (b) to analyse the validity of the easy-to-use and cost-effective instrument (smartphone camera, MOB) compared with gold-standard instrument (3D motion capture system, MOCAP) to obtain the vertical jump performance during HT. Twelve semi-professional high-level and fifteen amateur soccer male players (23.9 ± 3.6 years) performed three HT attempts, and kinematic data were recorded with MOB and MOCAP. Intra-class correlation coefficient (ICC) and coefficient of variation (CV) were used as measures of intra-session reliability. T-test with Cohen's effect size (ES), Pearson's product moment and Bland-Altman analysis were used to obtain MOB validity. Regarding intra-session reliability, the CV was 1.13%, and ICC was 0.98, considered acceptable. Respecting validity criteria did not reveal significant differences (p < 0.05; effect size = 0.06, considered trivial), 'almost perfect' correlation (Pearson) (r = 0.98; p < 0.05), and strong agreement were obtained between MOB and MOCAP. This finding showed a test (HT) with a specific character, using cost-effective instrument and applicable to all soccer fields (adjusted to the standardised lines in the soccer field), all of them backed-up by reliability, usefulness and validity criteria.

期刊介绍: ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
