摘要

背景:本研究的目的是为了检验后续动作对投球速度的影响,潜在地证明将后续动作纳入罗伯顿的五个关键组成部分。方法:78名大学生参加了一项用最大力量投掷一个标准网球三次的伸臂、优势手投掷任务。每次投掷都由放置在投掷者身后和开放侧的两台摄像机拍摄,以评估投掷技术。投掷的速度用雷达枪记录了下来。结果:结果表明,在考虑了性别、年龄和投掷经验的影响后,随动水平对投掷速度有显著影响。协方差分析也揭示了显著的性别效应,男性投掷明显快于女性。结果表明,在所有六个组成部分中,随动对抛球速度的影响都是第二大的。讨论:这些发现提供了初步的支持,跟进应该添加到罗伯顿的发展水平。加入跟进部分可以帮助教师和教练促进学习者和运动员的发展,也可以提高投掷发展评估的准确性。

Validation of a Follow-Through Developmental Sequence for the Overarm Throw for Force in University Students
Background: The purpose of this study was to examine the effect of the follow-through on thrown ball velocity, potentially justifying inclusion of the follow-through in Roberton’s five critical components. Method: Seventy-eight University students participated in the overarm, dominant hand, throwing task, which involved throwing a standard tennis ball with maximum force three times. Each throw was filmed by two cameras placed behind and to the open side of the thrower to assess the throwing technique. The velocity of the throws was recorded with a radar gun. Results: Results indicated that, after accounting for the effects of gender, age, and throwing experience, there was a significant effect of follow-through level on throw velocity. Analysis of covariance also revealed a significant gender effect, with males throwing significantly faster than females. Results indicated the follow-through had the second largest impact on thrown ball velocity of all six components. Discussion: These findings provide preliminary support that the follow-through should be added to Roberton’s developmental levels. The inclusion of the follow-through component could assist teachers and coaches to facilitate learner and athlete development and could also improve the accuracy of throwing development assessment.

期刊介绍: The Journal of Motor Learning and Development (JMLD) publishes peer-reviewed research that advances the understanding of movement skill acquisition and expression across the lifespan. JMLD aims to provide a platform for theoretical, translational, applied, and innovative research related to factors that influence the learning or re-learning of skills in individuals with various movement-relevant abilities and disabilities.
