The Lace-up group's center of pressure displacement quantity is bigger than other two groups,therefore its balance ability is also bad, therefore suggested the athlete when wearing ankle braces sports should inquire specialized doctor and the protection suggestion avoids injury.

人体在穿戴不同踝部护具执行单脚著地后迅速推蹬动作时， Lace-up和Air stirrup这两种护具在著地期间确实具有限制关节活动度的效果，但也因踝关节跖屈能力的下降造成人体著地时缓冲地面冲击力能力下降的现象，造成本研究结果在地面反作用力垂直分力Lace-up和Air stirrup组都较赤足组来的较大，著地时脚的负荷率Lace-up组和Air stirrup组都较赤足组来的较大，且Lace-up组在著地期压力中心偏移量也较其他两组大，故其平衡能力也有差异，故建议运动员在穿著踝部护具运动前应询问专业医师及防护员的建议以避免因此而受到伤害。
