This study expanded the database regarding the visual regulation of gait in the long jump approach (LJA) in the direction of novice long jumpers. It showed that the pattern of visual influence on gait adjustments was similar for novices and experts. This was taken to indicate that visual regulation of gait in the LJA is not a specially trained skill as much as it is a natural means of controlling gait. The study also showed that novices' step lengths were regulated principally by modifying vertical impulse. This finding replicated that of an influential study by D. N. Lee, J. R. Lishman, and J. A. Thomson (1982). Results are discussed with respect to the prevailing ecological notion that the optical variable tau provides principal informational support for regulation of gait in the LJA.
本研究朝着新手跳远运动员的方向扩展了关于跳远助跑(LJA)中步态视觉调节的数据库。研究表明,新手和专家在视觉对步态调整的影响模式上是相似的。这被认为表明在LJA中步态的视觉调节与其说是一种经过专门训练的技能,不如说是一种控制步态的自然方式。该研究还表明,新手的步长主要通过改变垂直冲量来调节。这一发现重复了D. N. 李、J. R. 利什曼和J. A. 汤姆森(1982年)一项有影响力的研究结果。针对当前的生态学观点,即光学变量tau为LJA中步态调节提供主要信息支持,对结果进行了讨论。
