The purpose of the study was to investigate the occurrence of stride regulation at the approach phase of the long jump in athletes with normal vision and visually deprived Class F12 and F13 athletes. All the athletes exhibited the presence of a regulatory mechanism. In the normal vision group this occurred on the fifth-to-last stride. In Class F12 athletes regulation commenced on the fourth-to-last stride for males and third-to-last stride for females. Class F13 males commenced regulation, like the control group, on the fifth-to-last stride; but females commenced on the fourth-to-last stride. The study demonstrated that reduced vision does not prevent Class F12 and F13 athletes from applying a regulatory mechanism similar to that observed in sighted athletes. However, the control mechanism of regulation emerged earlier in non-visually deprived long jumpers and the least visually impaired Class F13 athletes, signifying the importance of visual function in the regulatory stimuli.
本研究旨在探讨正常视力和 F12、F13 类视觉剥夺运动员在跳远助跑阶段的步幅调节情况。所有运动员都表现出存在调节机制。在正常视力组，这种情况发生在倒数第五步。在 F12 类男性运动员中，调节始于倒数第四步，而女性运动员则始于倒数第三步。F13 类男性运动员与对照组一样，在倒数第五步开始调节；而女性运动员则在倒数第四步开始调节。研究表明，视力降低并不能阻止 F12 和 F13 类运动员应用类似于视力正常运动员的调节机制。然而，在非视觉剥夺跳远运动员和视力受损程度最低的 F13 类运动员中，调节的控制机制更早出现，这表明视觉功能在调节刺激中的重要性。
