概括
同时重复的异动力学腿筋:四肢 (H:Q) 强度测试可能导致错误的负伤害风险分类. 然而,使用来自并发试验的未经纠正的数据与纠正的单独试验相比,不会显著改变H:Q比率.
科学领域:
- 生物力学 生物力学
- 运动医学 运动医学
- 人类运动科学科学 人类运动科学
背景情况:
- 肌肉平衡和受伤风险的评估中,四头肌 (H:Q) 的强度比率至关重要.
- 在H:Q测试中常见的并发重复协议可能会受到拉伸缩短周期和轴不对齐的影响.
- 建议使用孤立的重复协议来缓解这些混因素.
研究的目的:
- 调查并发与孤立的重复协议对H:Q强度比的影响.
- 检查轴不对齐校正对H:Q比率的影响.
- 为开发更准确的肌肉失衡查方案提供信息.
主要方法:
- 15名健康的男性进行了以60°/s的异动力膝盖曲器和延伸器测试,使用并发和孤立的重复协议.
- 射手平面动力学被捕获在100赫兹以评估轴不对齐.
- 使用统计参数映射来比较协议类型和轴校正的影响.
主要成果:
- 未经纠正的数据低估了离散的常规和功能H:Q比率以及所有角度特定比率.
- 同时重复显著高估了传统的H:Q比,特别是在更延伸的膝盖位置 (24°-45°).
- 尽管对并发试验进行过高估计,但使用来自并发重复的未经校正的数据并没有产生与纠正的孤立重复相比显著不同的离散或角度特定的H:Q比率.
结论:
- 同时重复的协议可能会增加由于高估H:Q比率的错误负面伤害风险评估的可能性.
- 与纠正的孤立重复相比,使用来自并发重复的未经纠正数据的常见做法可能不会显著影响离散或角度特定的H:Q比率结果.
- 临床医生和研究人员在解释伤害风险查的H:Q强度比数据时,应该意识到这些协议特定的差异.

01:16Bones of the Lower Limb: Femur and Patella
2.0K
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...

01:23Muscles that Move the Leg

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...
