概括
二次跳跃方向在前十字带 (ACL) 损伤风险评估中显著影响着陆生物力学. 多平面跳跃显示出更大的膝盖曲,强调了预防计划中需要进行多样化的测试.
科学领域:
- 生物力学 生物力学
- 运动医学 运动医学
- 整形外科 整形外科 整形外科
背景情况:
- 前十字带 (ACL) 损伤在体育运动中很常见,通常是由降落和切割运动中的非接触机制造成的.
- 之前的研究已经检查了ACL损伤的生物力学风险因素,使用二次跳跃的跳下跳跃任务.
研究的目的:
- 为了研究二次跳跃的方向如何影响着陆阶段的动力学数据.
- 评估单平面与多平面二次跳跃对下肢和体着陆动力学的影响.
主要方法:
- 57名参与者进行了单脚下降跳跃,随后在垂直 (单平面),45°中间和45°侧面 (多平面) 方向进行了二次跳跃.
- 一个9摄像头的运动捕捉系统记录了下肢和干运动.
- 使用单向ANOVA的统计参数映射 (SPM) 分析了从初始接触到膝盖最大曲的动力学数据.
主要成果:
- 二级跳转方向影响了大多数动力学变量,只有旋是例外.
- 与单平面任务相比,多平面任务的结果是形平面中的干部,部和膝盖曲显著增加.
- 前面平面动力学受到二次跳跃的中侧元件的显著影响.
结论:
- 单个测试任务可能不足以准确评估前十字带 (ACL) 损伤风险.
- 建议在全面的ACL伤害预防和康复评估中将单层和多层次的次级跳跃纳入其中.
- 建议在使用不同次级跳跃任务的研究结果进行比较时谨慎.

Absolute Motion Analysis- General Plane Motion
219
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...

Kinematic Equations - II
9.5K
The second kinematic equation expresses the final position of an object in terms of its initial position, the distance traveled with the initial constant velocity, and the distance traveled due to a change in velocity. Similar to the first kinematic equation, this equation is also only valid when the acceleration is constant throughout the motion of an object.
Suppose a car merges into freeway traffic on a 200 m long ramp. If its initial velocity is 10 m/s and it accelerates at 2 m/s2, then the...
