像减小步长或轻轻地跑步这样的跑步步骤可以在舒适的步伐下减少骨加速. 然而,这些线索在中度跑步时不会显著影响 acceleration.
科学领域:
- 生物力学 生物力学
- 运动科学 运动科学 运动科学
- 跑步伤害预防 跑步伤害预防
背景情况:
- 重复的跑步冲击与常见的跑步伤害有关.
- 骨加速作为一个代理的骨负载在运行过程中.
- 减少 acceleration 的干预措施对跑步者有很大的兴趣.
研究的目的:
- 为了研究特定的跑步步态对峰值垂直 acceleration 的影响.
- 为了确定这些线索在舒适和适度的跑步步伐下如何影响部加速.
- 评估跑步步态的执行及其生物力学影响.
主要方法:
- 27名参与者在各种步态条件下在跑步机上进行了跑步练习.
- 步行线索包括:轻轻地奔跑,减少步长,增加步速.
- 使用安装在骨上的惯性测量单元传感器,以舒适和适度的步伐测量 acceleration.
主要成果:
- 在舒适的跑步过程中,减少步骤长度和轻轻地/轻轻地跑步显著降低了峰值垂直部加速.
- 增加步速并没有导致小腿加速发生显著变化.
- 在中度跑步期间,在任何提示下,没有观察到峰值垂直腿加速的显著减少.
结论:
- 跑步步态度再训练策略,如减少步长或轻轻地跑步,可以在舒适的跑步速度下轻微减少脚加速.
- 跑步步伐暗示在中度跑步步伐期间对骨加速没有显著影响.
- 个别执行的线索可能会影响整体的小腿骨负荷,为跑步再训练提供生物力学见解.

Relative Motion Analysis - Acceleration
Measuring Acceleration Due to Gravity
A simple pendulum can be described as a point mass and a string. Meanwhile, a physical pendulum is any object whose oscillations are similar to a simple pendulum, but cannot be modeled as a point mass on a string because its mass is distributed over a larger area. The behavior of a physical pendulum can be modeled using the principles of...
