脚踝支撑和绷带通常用于预防脚踝扭伤，并在受伤后恢复比赛，然而，被动限制关节运动如何影响跑步步态运动学和运动中的能量消耗尚不清楚。本研究的目的是为了确定不同类型的踝关节支撑对连续跑过程中腿部运动学和能量消耗的影响。13名健康体力活动的成年人在跑步机上以自己选择的速度在四种不同的踝关节支撑条件下跑步30min：半刚性铰链支撑、系带支撑、带状支撑和对照。每隔5分钟记录一次肢体三维运动学和能量消耗情况。半刚性铰链支具对额面踝关节活动的限制效果最好。系带支撑和带子限制了矢状面踝关节的运动，而半刚性铰链支撑允许正常的矢状面踝关节运动学。在25-30分钟的锻炼中，所有三个脚踝支撑的运动学变化通常都是持续的。只有胶带影响膝关节运动学，限制屈曲速度和屈伸偏移。在胶带和半刚性铰链支撑条件下，能量消耗有小幅但显著的增加；然而，增加不到任何实际显著的水平(<；0.5kcal/min)。
Ankle braces and taping are commonly used to prevent ankle sprains and allow return to play following injury, however, it is unclear how passive restriction of joint motion may effect running gait kinematics and energy expenditure during exercise. The purpose of this study was to determine the effect of different types of ankle supports on lower extremity kinematics and energy expenditure during continuous running. Thirteen healthy physically active adults ran at self-selected speed on the treadmill for 30 min in four different ankle support conditions: semi-rigid hinged brace, lace-up brace, tape and control. Three-dimensional lower extremity kinematics and energy expenditure were recorded every five minutes. The semi-rigid hinged brace was most effective in restricting frontal plane ankle motion. The lace-up brace and tape restricted sagittal plane ankle motion, while semi-rigid hinged bracing allowed for normal sagittal plane ankle kinematics. Kinematic changes from all three ankle supports were generally persistent through 25-30 min of exercise. Only tape influenced knee kinematics, limiting flexion velocity and flexion-extension excursion. Small but significant increased in energy expenditure was found in tape and semi-rigid hinged brace conditions; however, the increases were not to any practically significant level (< 0.5 kcal/min).
