摘要

背景:注意力是大脑最重要的认知功能之一,在运动技能的发挥中起着关键作用。目的:探讨与任务相关和与任务无关的注意线索和技能水平对立定跳远成绩和膝关节运动学的影响。方法:招募15名技术熟练(排球和篮球运动员)和15名新手(年龄19至27岁)。该任务是站立跳远测试,在3种条件下进行9次(每种条件进行3次试验)。处于对照状态的参与者没有接受任何注意指导。在与任务相关的注意力线索条件下,参与者被要求专注于他们正在进行的技能,避免关注与任务无关的事情。在与任务无关的注意力线索条件下,参与者被要求专注于声音,并在每次跳跃后表达音乐内容。膝关节运动数据采用8摄像机运动分析系统进行记录。结果:混合方差分析结果显示,与任务相关的注意线索条件(p=0.001)和对照组(p=0.001结论:研究结果表明,将注意力集中在与任务无关的注意力线索上,可以提高新手和熟练跳高运动员的站立跳远成绩。

The effect of task-relevant and task-irrelevant attentional cues and skill level on performance and knee kinematics of standing long jump
Background: Attention is one of the brain's most crucial cognitive functions playing a key role in performing motor skills. Objective: The purpose of the present study was to investigate the effect of task-relevant and task-irrelevant attentional cues and skill level on performance and knee kinematics of standing long jump. Methods: Fifteen skilled (volleyball and basketball players) and fifteen novices (aged 19 to 27 years) were recruited. The task was the standing long jump test which was executed 9 times under 3 conditions (3 trials per condition). Participants in the control condition did not receive any attentional instruction. In task-relevant attentional cues condition, participants were instructed to focus on their ongoing skill and avoid paying attention to matters unrelated to the task. In task-irrelevant attentional cues condition, participants were instructed to focus on sound and after each jump expressed what had been the musical content. Kinematic data of knee joint was recorded by an 8-camera motion analysis system. Results: The result of mixed ANOVA showed that both novice and skilled groups had significantly greater jump distance and smaller initial knee angle in task-irrelevant attentional cues condition compared to task-relevant attentional cues condition (p = .001) and control condition (p = .001). There were no significant differences between the control and task-relevant attentional cues condition (p > .05). Conclusions: The result showed that focusing attention on task-irrelevant attentional cues improves standing long jump performance of both novice and skilled jumpers.
