概括
对于膝盖受伤的年轻运动员来说,改善膝盖力量在第一年内并没有显著提高跳跃距离或平衡. 这表明,在运动膝盖受伤后,其他因素对功能恢复更为关键.
科学领域:
- 整形外科 整形外科 整形外科
- 运动医学 运动医学
- 康复科学 康复科学 康复科学
背景情况:
- 评估年轻运动员受伤后膝关节肌肉力量和功能恢复之间的联系对于有效的康复至关重要.
- 青少年运动相关的膝盖伤害往往导致时间损失,并可能影响长期的关节健康.
研究的目的:
- 确定膝盖延伸器和屈曲器强度的变化与运动相关膝盖受伤后年轻人腿部功能的测量之间的关联.
- 在12个月内调查力量增强与基于表现和自我报告的功能结果之间的关系.
主要方法:
- 一项前性队列研究分析了106名年轻人 (11-19岁) 最近受伤膝盖的数据.
- 评估了基线,6个月和12个月的异动力膝盖强度 (峰值扭矩),三跳距离,Y平衡测试 (YBT) 和膝盖损伤和关节炎结局得分 (KOOSsport).
- 多变量回归模型评估了强度和功能的变化之间的关联.
主要成果:
- 膝盖延伸器强度增加1Nm (6-12个月) 显示与改善跳跃距离 (0.9厘米) 的非显著关联.
- 同样,膝盖曲器强度的增加与跳跃距离和自我报告的功能 (KOOSsport) 有很小的关联.
- 强度变化和YBT表现之间没有发现显著的纵向关系.
结论:
- 在膝关节受伤后的第一年内,年轻人的强度改善和功能恢复之间存在最小的或没有纵向关系.
- 这些发现强调,除了单独的膝关节肌肉强度之外的因素可能会影响年轻运动员的功能结果.
- 需要进一步的研究,以确定成功康复和恢复运动的关键预测因素.

Muscles that Move the Leg
2.8K
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...

Bones of the Lower Limb: Femur and Patella
2.9K
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 Thigh
1.5K
The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar...

Disorders of the Skeletal Muscle
1.1K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
