概括
前十字带重建 (ACLR) 后的运动员在重复跳跃时显示出四头四头和腿筋肌肉激活的改变. 这些神经肌肉缺陷,特别是肌肉激活的时间和水平,可能会增加再次受伤的风险,并且可以通过跳测试来检测.
科学领域:
- 运动医学 运动医学
- 生物力学 生物力学
- 康复科学 康复科学 康复科学
背景情况:
- 经过前十字带重建 (ACLR) 的运动员通常会经历四头骨和腿筋强度以及神经肌肉控制的减少.
- 这些缺陷与肌肉激活障碍有关,可能增加再次受伤的风险,并导致早期膝关节退行.
研究的目的:
- 在经过ACLR的运动员中,在重复跳跃时调查四头四和腿筋肌肉激活模式.
- 将这些激活模式与参与旋转运动的健康运动员的激活模式进行比较.
主要方法:
- 表面电肌图 (SEMG) 用于双边记录四头肌 (大中,大侧) 和腿筋 (中,侧) 的肌肉激活.
- 在30秒的重复跳跃测试中,在ACLR (腿筋或骨骨移植) 后5-12个月的男性运动员 (n=44) 和健康对照组 (n=31) 中进行了测量.
- 将SEMG信号正常化为最大自发的同度收缩.
主要成果:
- 与对照人群相比,患有ACLR的运动员,特别是患有腿筋移植的运动员,在四头肌肌肉中表现出较早的峰值肌肉激活.
- 观察到高峰肌肉激活水平的显著差异,受伤腿部下四头肌激活,受伤腿部侧腿筋活动减少,与对照组相比.
- 在跳跃周期期间,在所有组中都注意到中间腿筋激活的下降.
结论:
- 重复的跳跃测试揭示了ACLR运动员的四头肌和腿筋肌肉激活的显著差异,无论是在ACLR组内还是与健康对照组相比.
- 这些激活缺陷,包括改变时间和降低水平,可能会被单跳测试遗漏,并突出显示ACLR后潜在的神经肌肉损伤.
- 这些发现强调了ACLR运动员综合神经肌肉评估的重要性,以指导康复和恢复运动的决策.

Bones of the Lower Limb: Femur and Patella
2.5K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Muscles that Move the Leg
1.7K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

Muscles of the Leg that Move the Foot and Toes

The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....
