概括

疲劳显著改变了体重 (BWS) 的动力学,影响了关节的速度和运动范围,特别是在具有不同下肢肌肉比率 (LLMR) 的运动员中. 在非疲劳的坐中观察到的"粘着区域"随着疲劳而消失.

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:

疲劳是影响运动表现和运动质量的关键因素.
了解疲劳运动期间的动力学变化对于优化训练和预防伤害至关重要.
体重 (BWS) 是一种基本的炼,但其在疲劳时的动力学适应性尚未完全阐明.

研究的目的:

为了研究疲劳对动力学参数的详细影响,在身体重量坐 (BWS) 练习.
分析疲劳如何影响坐周期的不同阶段和关节动力学.
探索疲劳,下肢肌肉比率 (LLMR) 和动力学变化之间的潜在相互作用.

主要方法:

21名男性运动员进行了BWS,直到意志疲劳.
使用运动分析软件收集了运动数据 (线性和角度).
参与者根据他们的下肢肌肉比率 (LLMR) 进行分组.
Squat 周期被分为不同的阶段进行详细分析.

主要成果:

疲劳在不同坐阶段显著影响了各种动力学参数,观察到显著的主要影响 (0.01 < p < 0.05).
在疲劳时的肩和关节速度之间出现了一个多项式关系,与非疲劳状态中的线性关系形成鲜明对比.
"坚持区域",一个减速点,在非疲劳的坐中存在,但随着疲劳而消失.
疲劳和LLMR之间的相互作用显示,在曲制动阶段,膝盖延伸运动范围 (ROM) 和部角速度的效应大,但在统计学上并不显著 (0.08 > p > 0.05).

结论:

下肢肌肉比率 (LLMR) 可能需要在式炼处方和分析中考虑.
在基于速度的式训练期间的动力追踪可能需要调整,考虑到疲劳引起的变化.
在实施体重坐训练计划之前,预先测试以确定"粘着区域"可能是有益的.

Fatigue

Fatigue

Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

Relating Angular And Linear Quantities - I

Relating Angular And Linear Quantities - I

If the rotational definitions are compared with the definitions of linear kinematic variables from motion along a straight line and motion in two and three dimensions, we can observe a mapping of the linear variables to the rotational ones.
When comparing the linear and rotational variables individually, the linear variable of position has physical units of meters, whereas the angular position variable has dimensionless units of radians, as it is the ratio of two lengths. The linear velocity...
