Optimal postural stability is required to perform in archery. Since the dynamic consequences of the string release may disturb postural equilibrium, they should be integrated into an archer motor programme to optimize postural stability. This study aimed to characterize the postural strategy archers use to limit the potentially detrimental impact of the bow release on their postural stability and identify characteristics that may explain a better performance. Six elite and seven sub-elite archers performed a series of 18 shots at 70 metres, standing on two force plates. Postural stability indicators were computed during the aiming and the shooting phase using the trajectory of the centre of pressure. Two postural strategies were defined, as whether they were triggered before (early) or after (late) the string release time. Both groups used anticipated postural adjustments, but elite archers triggered them before the string release more often and sooner. Scores differed between the two groups, but no differences were found between early and late shots. Trained archers seem to have finely integrated the dynamic consequences of their bow motion, triggering anticipated postural adjustments prior to the string release. However, it remains unclear whether this anticipation can positively influence the performance outcome.
射箭需要最佳的姿势稳定性。由于弓弦释放的动力后果可能会扰乱姿势平衡，因此应将其纳入弓箭手的运动计划中，以优化姿势稳定性。本研究旨在描述弓箭手用来限制弓弦释放对其姿势稳定性的潜在不利影响的姿势策略，并确定可能解释更好表现的特征。六名精英射手和七名次精英射手在 70 米处的两个测力板上进行了一系列 18 次射击。使用压力中心轨迹在瞄准和射击阶段计算姿势稳定性指标。根据是否在弓弦释放时间之前（早期）或之后（晚期）触发，定义了两种姿势策略。两组都使用了预期的姿势调整，但精英射手更频繁和更早地在弓弦释放之前触发了这些调整。两组之间的得分存在差异，但早期和晚期射击之间没有差异。训练有素的弓箭手似乎已经很好地整合了他们的弓动的动力后果，在弓弦释放之前触发预期的姿势调整。然而，目前尚不清楚这种预期是否能对表现结果产生积极影响。
