The purpose of this study was to quantify differences in barbell back squat stability as a function of gaze direction. Sixteen female subjects who were experienced in barbell back squatting performed six sets of three squat repetitions, randomized according to three gaze directions (DOWN, STRAIGHT, and UP). Stability was determined based on the displacement of center of pressure (COP) during each squat repetition, measured using a low-cost, portable force plate. Multiple t-tests with statistical significance set at p < 0.05 were conducted between gaze directions and revealed significant differences in stability between the DOWN versus UP conditions. Specifically, DOWN had the smallest COP displacement, with significantly larger COP displacement in the UP condition (p = 0.02). There were no significant differences when DOWN or UP was compared to STRAIGHT (p = 0.22 and p = 0.28 respectively). From a practical standpoint, these results suggest that having a downward gaze direction during barbell back squat will maximize stability and reduce the likelihood of injury.

这项研究的目的是量化与视线方向有关的杠铃后蹲稳定性的差异。十六名有杠铃后蹲经验的女性受试者进行了六组三下蹲重复，并根据三个注视方向（下，直和上）进行了随机分组。根据每次下蹲重复过程中压力中心（COP）的位移来确定稳定性，使用低成本的便携式测力板进行测量。在注视方向之间进行了多个统计显着性设置为p <0.05的t检验，结果表明DOWN和UP条件之间的稳定性存在显着差异。具体而言，DOWN具有最小的COP位移，而在UP条件下具有显着更大的COP位移（p = 0.02）。当将DOWN或UP与STRAIGHT进行比较时，没有显着差异（分别为p = 0.22和p = 0.28）。从实际的角度来看，这些结果表明，在杠铃后蹲期间具有向下的注视方向将最大程度地提高稳定性并减少受伤的可能性。
