视觉-距离知觉信息整合对跳远起跳踏板技能习得的影响

Influence of Visual-Distance Perception Integration on Long Jump Take-off Skills

目的:验证视觉-距离知觉信息整合对跳远起跳踏板准确性、稳定性和起跳踏板距离预测准确性、稳定性的影响。方法:采用单因素实验设计,选取某体育学院48名大一新生作为被试,将被试分为视觉信息组、距离知觉信息组、视觉+距离知觉信息组,进行8周的实验干预,采用前测、后测的方法对指标进行测试;对起跳踏板和距离预测的绝对误差(AE)、绝对常数误差(ACE)、变异误差(VE)等指标进行统计分析。结果:视觉-距离知觉信息整合能够提高起跳踏板的前后上板准确性、左右上板一致性,降低前后上板误差;能够提高跳远起跳踏板前后和左右上板距离预测准确性、降低前后上板距离预测误差;对起跳踏板的前后上板一致性、左右上板准确性、左右上板误差,以及前后和左右上板距离预测一致性、左右上板距离预测误差的影响不明显。结论:视觉-距离知觉信息整合对提高跳远起跳踏板的准确性、稳定性、降低犯规或不上板的几率具有促进作用;视觉-距离知觉信息整合对提高起跳踏板的距离知觉预测技能的准确性、稳定性具有促进作用。

Objective： This paper verified the influence of visual-distance perception integration on accuracy and stability of long jump take-off skills and distance perception. Methods： With a single factor design,48 male freshmen were recruited in this study,and were divided into visual group（ VG）,distance perception group（ DPG）and visual-distance perception group（ VDPG）,they were finished 8 weeks training,and the data was tested before and after eight weeks training. Absolute error（ AE）,absolute constant error（ ACE）,variable error（ VE） of the long jump take-off skills and distance perception were analyzed. Results： Visual-distance perception integration improved linear accuracy,lateral consistency,and reduced linear error of long jump＇s take-off skills; improved linear and lateral distance perception accuracy,and reduced linear distance perception error of long jump＇s take-off skills. The effects of visual-distance perception integration on linear consistency,lateral accuracy,lateral error,linear and lateral distance perception consistency,lateral distance perception error were not different. Conclusions： Visual-distance perception integration can improve the accuracy and stability of long jump take-off skills,can reduce the chance of foul or no upper; it can improve the accuracy and stability of distance perception prediction of long jump take-off skills.
