概括

增加分裂的步骤长度可以增强部伸缩器的激活,但对膝盖伸缩器的影响很小. 力量训练的最佳步骤长度等于个体下肢长度,考虑到运动范围,关节时刻和肌肉激活,以实现个性化的运动处方.

科学领域:

生物力学生物力学
运动生理学运动生理学
运动科学运动科学运动科学

背景情况:

分裂是用于下半身力量和康复的常见炼.
了解运动技巧的变化,如步骤长度,如何影响生物力学,对于优化训练和预防伤害至关重要.

研究的目的:

量化增加分裂坐步骤长度对下肢动力学,动力学和肌肉激活的影响.
确定最佳的步骤长度,以最大限度地提高健康成年人力量训练的益处.

主要方法:

20名健康的男性大学生进行了四种不同步骤的四分.
动力学,动力学和电肌学 (EMG) 数据收集了下肢的数据.
单向重复测量 ANOVA 用于分析峰值关节角度,时刻和肌肉激活的差异.

主要成果:

增加的步骤长度显著改变了部,膝盖和脚关节的角度和部/膝盖延伸的时刻.

结论:

在分裂式坐中,更长的步骤长度优先激活部伸展肌肉,对膝盖伸展器的影响有限.
运动范围,关节时刻和领头四肢的肌肉激活应考虑在预防和康复背景下进行个性化的运动处方.
建议在健康的成年人进行力量训练时,最优的步骤长度大约等于个体的下肢长度.

Muscles of the Leg that Move the Foot and Toes

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....

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...
