概括
板球快投手使用前腿作为动力,但它的功能主要是通过受控制动,而不是积极延伸. 专注于全身的动量,以获得更好的球速度,而不仅仅是孤立的腿部力量.
科学领域:
- 生物力学 生物力学
- 运动科学 运动科学 运动科学
- 板球表现分析 板球表现分析
背景情况:
- 快投手在前脚接触阶段使用前腿作为关键的机械杆.
- 了解控制前腿行为的精确机制对于优化保龄球表现和预防伤害至关重要.
研究的目的:
- 为了调查板球快速投球动作期间前腿的关节力和角度冲动.
- 为了确定部和膝盖延伸-曲力学的功能性作用 (主动与控制).
- 确定球速的关键动态和人体测量预测因素.
主要方法:
- 利用14个摄像头的3D运动捕捉系统和强力平台来分析18名初级快投手.
- 从前脚接触到球释放的部和膝盖的量化关节力量和角度冲动.
- 采用多重线性回归来评估动力学和人类学对球速度的贡献.
主要成果:
- 前腿运动主要以部和膝关节的受控 (异常) 力量为特征.

Mechanism of Ciliary Motion
5.3K
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Mechanical Protein Functions
5.7K
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

Absolute Motion Analysis- General Plane Motion
605
Visualize a drone, with its propellers spinning rapidly, hovering mid-air. The fascinating movements and operations of this drone can be comprehended by applying the principle of general plane motion.
As the drone's propellers rotate, an upward force is generated that counteracts the force of gravity, enabling the drone to lift off from the ground. This initial movement of the drone is along a straight path, representing a form of translational motion. In this phase, every point on the...

Muscles that Move the Leg
5.4K
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...
