The study investigated the effect of metatarsal strapping on vertical jump performance and evaluated the difference in lower limb kinematics and electromyographic signal (EMG) between different strapping force levels. Twelve male callisthenic athletes completed single vertical jump from a squat posture with hands on hips under three conditions as non-strapping (NS), moderate strapping (MS) and high strapping (HS) round metatarsals. Ground reaction force (GRF) was recorded with KISTLER force platform to calculate the vertical jump height. Angles of ankle, knee and hip were measured with VICON motion analysis system and EMG data were recorded with mega6000 system. Data showed that jump height was significantly higher under HS than NS condition. Compared with NS, ankle inversion decreased significantly during take-off and external rotation increased significantly during landing with MS. Significant difference was also found in the muscle activity of tibialis anterior between non-strapping and strapping conditions.
该研究调查了跖骨绑扎对垂直跳跃性能的影响，并评估了不同绑扎力水平下下肢运动学和肌电信号（EMG）的差异。12名男性健美操运动员在三种情况下，即无绑扎（NS）、中度绑扎（MS）和高度绑扎（HS）环绕跖骨，从双手叉腰的深蹲姿势完成单次垂直跳跃。使用奇石乐测力平台记录地面反作用力（GRF）以计算垂直跳跃高度。使用VICON运动分析系统测量踝关节、膝关节和髋关节的角度，并使用mega6000系统记录肌电数据。数据显示，HS条件下的跳跃高度显著高于NS条件。与NS相比，MS在起跳时踝关节内翻显著减少，在着陆时外旋显著增加。在无绑扎和绑扎条件之间，胫骨前肌的肌肉活动也发现了显著差异。
