概括
较高的着陆高度会损害脚自身感受,而降落策略和性别不会显著地影响它. 脚自身感知性能与着陆高度相关,但与策略无关.
科学领域:
- 生物力学 生物力学
- 人类运动科学科学 人类运动科学
- 运动医学 运动医学
背景情况:
- 脚亲感对于平衡和预防伤害至关重要.
- 了解影响着陆时脚自身感受的因素对于开发有效的训练和康复策略至关重要.
研究的目的:
- 为了研究着陆高度,下降策略 (下降与下降) 和性别对脚亲感的影响.
- 为了检查脚亲感表现和着陆条件之间的相关性.
主要方法:
- 这是一项涉及34名参与者 (21名男性,13名女性) 的横截面研究.
- 在15厘米和30厘米的高度下降时,使用定制的脚反转区分装置 (AIDAL) 评估了脚亲感.
- 接收器操作曲线下的面积 (AUC) 用于量化自感歧视. 分析使用了三向重复测量ANOVA和皮尔森的相关性.
主要成果:
- 降落高度增加 (30厘米与15厘米相比) 显著恶化了脚亲感表现 (p=0.019).
- 下降策略和性别没有显示出对脚亲感的重大主要影响或相互作用.
- 脚亲感表现出同一策略内的不同降落高度之间的中等相关性 (r=0.400-0.430,p=0.012-0.031),但不同策略之间没有.
结论:
- 降落高度显著影响脚亲感,较高的降落导致性能差.
- 下降策略和性别似乎不是影响着陆期间脚亲感的重要因素.
- 研究结果表明,着陆高度是自感评估和训练的关键变量,而降落策略可能的影响较小.

Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

The ankle and foot provide the foundation for the body and the stability needed for upright posture and ambulation. Because of its weight-bearing function, the ankle joint is a common site of injury among athletes and in the general population. Ankle injuries occur as a result of both acute trauma and repetitive overuse (such as running). The ankle is a fairly simple joint, consisting of the articulation between the...
