概括

在走路或跑步时携带负载会增加垂直地面反应力 (vGRF) 和下肢硬,可能会增加受伤风险. 在泡表面的运动也会提高这些生物力学因素,特别是在男性身上.

科学领域:

生物力学生物力学
人类运动科学科学人类运动科学
运动医学运动医学

背景情况:

了解外部负荷和表面特性对人类运动的影响,对于预防伤害至关重要.
以前的研究已经探索了影响地面反应力和下肢硬性的因素,但对性别,步态,负载和表面的全面分析是有限的.

研究的目的:

量化体载负荷和表面类型对垂直地面反应力 (vGRF) 和走路和跑步时下肢硬度的影响.
在各种运动条件下比较男性和女性之间的生物力学反应.

主要方法:

9名男性和9名女性进行了步行 (1.3米/秒) 和跑步 (4.5米/秒) 试验.
试验是在固体和软体泡表面上进行的,并没有15公斤的体载载荷.
使用线性混合模型测量和分析了垂直地面反应力 (vGRF) 和下肢关节硬度.

主要成果:

负载行走和跑步显著增加了vGRF和下肢硬度 (分别P <.016和P <.033).
泡表面在两种步态中增加了峰值vGRF和膝盖硬度,并在跑步时增加了腿/脚硬度 (P < .025).
与女性相比,男性在行走时表现出更大的峰值vGRF和部/脚硬度,并在跑步时在泡上表现出更大的膝盖硬度.

结论:

负载行走和跑步,以及在符合泡表面上的运动,可能会增加由于升高的vGRF和性而导致下肢受伤的风险.
生物力学反应的性别特异性表明受伤易感性各不相同,男性在泡表面的风险可能更高.

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

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...

Bones of the Lower Limb: Tibia and Fibula

The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
