摘要

目的。后蹲(BS)是一种流行的运动,因为它能够发展下肢力量。在BS过程中,躯干倾斜和膝关节活动范围(roM)是正确技术的相关方面,这些运动运动学参数可以通过将官方举重鞋的鞋跟提高到离地面13毫米来积极改变。坡跟是将鞋跟提升到不同高度的一种低成本替代方案,但在25毫米以上的较高高度,运动运动学适应并没有在文献中得到很好的描述。因此,我们比较了不同高度的鞋跟楔对BS运动学的影响。方法。有经验的业余举重运动员15名(22±5.4岁);83±11公斤;179±6厘米;5±2.1年BS工作经验)。采用三种随机条件:赤脚(B), 25毫米(W25)和50毫米楔形(W50)。利用光电摄像系统对BS运动进行运动学分析。结果。方差分析后,事后显示显著的roM差异减少躯干(F = 27.27;p < 0.01)和膝关节升高(F = 16.87;P < 0.01)。事后分析证实树干倾斜度减小(B > W25 > W50;p < 0.05),膝关节升高(B < W25 < W50;p < 0.05)。结论。较高的楔形可以通过促进更直立的躯干位置和更大的BS深度来实现积极的适应。在各种训练环境和环境中,使用楔形鞋跟是优化BS技术的一种低成本和可行的策略。

Comparing the kinematics of back squats performed with different heel elevations
Purpose. Back squat (BS) is a popular exercise owing to its capacity to develop lower limb strength. During BS, trunk incli­ nation and knee range of motion (roM) are relevant aspects of a proper technique, and these movement kinematics parameters can be positively altered with official weightlifting shoes lifting the heel 13 mm above the ground. Wedges are a low­cost alternative to lifting the heel to different heights, but movement kinematics adaptations with higher elevations, above 25 mm, are not well described in the literature. thus, we compared the effect of different heights of heel wedges on BS kinematics. Methods. Fifteen experienced recreational weightlifters (22 ± 5.4 years; 83 ± 11 kg; 179 ± 6 cm; 5 ± 2.1 years of BS experience) were conveniently selected. three randomized conditions were applied: barefoot (B), 25­mm (W25), and 50­mm wedges (W50). BS movement was assessed by kinematic analysis with an optoelectronic camera system. Results. After ANOVA, the post­hoc indicated significant roM differences in reducing trunk ( F = 27.27; p < 0.01) and increasing knee ( F = 16.87; p < 0.01) flexions between conditions. Post­hoc analysis verified decreasing trunk inclination (B > W25 > W50; p < 0.05) and increasing knee (B < W25 < W50; p < 0.05) roM with increasing wedge height. Conclusions. Higher wedges allowed positive adaptations by promoting a more upright trunk position and greater BS depth. Using a heel wedge can be a low­cost and viable strategy to optimize BS technique in a variety of training settings and contexts.
