概括

男性足球运动员有腿筋应变损伤 (HSI) 史,在冲刺期间表现出改变的肌肉激活模式. 在HSI组中,较低的脏和干部肌肉活动可能会在早期立场阶段增加受伤风险.

科学领域:

运动医学运动医学
生物力学生物力学
运动生理学运动生理学

背景情况:

腿筋应变损伤 (HSI) 在男性足球运动员中很常见.
了解冲刺期间的肌肉激活模式对于预防伤害至关重要.

研究的目的:

描述和比较在加速冲刺过程中男性足球运动员的肌肉活动,有或没有史以来的HSI.
确定可能导致HSI风险的生物力学差异.

主要方法:

电肌图 (EMG) 用于评估26名男性足球运动员中10个肌肉的活动 (13名有HSI史,13名健康).
分析了30米最大冲刺期间的肌肉活动,分为跑步步的五个阶段.
统计分析涉及反复测量双向ANOVA和邦费罗尼后期测试.

主要成果:

在各组之间观察到最大肌肉 (Gmax),中部肌肉 (Gmed) 和外部斜 (EO) 肌肉活动的显著差异.
与健康组相比,HSI组的Gmax活性降低了30%,EO活性降低了20%,Gmed活性提高了40%.
在早期的立场阶段,HSI集团表现出较高的伤害风险,与典型的晚期摇摆阶段风险相反.

结论:

在HSI组中,干部和部肌肉激活的改变,特别是Gmax和EO活动的降低,可能会使他们在冲刺的早期立场阶段容易受伤.
这些发现凸显了针对部和干部肌肉强化的重要性,以预防足球运动员的HSI.

Classification of Skeletal Muscle Fibers

Classification of Skeletal Muscle Fibers

Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

Exercise and Muscle Performance

Exercise and Muscle Performance

Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
