During a back tuck somersault, the angular velocity of the head is thought to surpass the visual system's ability to maintain a distinct and continuous picture of the environment. The primary objectives of this research were to determine if differences existed with regard to trunk and lower body kinematics, as well as landing balance, when gymnasts perform back tuck somersaults under different vision conditions. Ten female gymnasts (age = 11.6 +/- 2.67 years, competitive level = 8 +/- 1.15, and training time in gymnastics = 5.9 +/- 1.63 years) performed back tuck somersaults under 4 vision conditions while wearing electromagnetic sensors that allowed automatic digitizing. Although no significant differences were found between vision conditions with regard to timing, joint angles, and joint angular velocities, gymnasts were more stable at landing under conditions that allowed vision during either the entire somersault or the last half of the sumersault.
在向后团身翻腾时，头部的角速度被认为超过了视觉系统维持清晰连续环境图像的能力。本研究的主要目的是确定体操运动员在不同视觉条件下进行向后团身翻腾时，躯干和下肢的运动学以及落地平衡是否存在差异。十名女性体操运动员（年龄 = 11.6 ± 2.67岁，竞技水平 = 8 ± 1.15，体操训练时间 = 5.9 ± 1.63年）在佩戴电磁传感器以便自动数字化的情况下，于4种视觉条件下进行向后团身翻腾。尽管在视觉条件之间未发现关于时间、关节角度和关节角速度的显著差异，但体操运动员在整个翻腾过程或翻腾最后半程允许视觉的条件下落地时更稳定。
