概括

应用在膝盖上的动力磁带 (KT) 通过增加地面反应力和减少地面接触时间,提高了在落地跳跃着陆 (DJL) 期间的反应强度. 这表明KT可以提高运动表现,并可能降低受伤风险.

科学领域:

生物力学生物力学
运动科学运动科学运动科学
整形外科整形外科整形外科

背景情况:

降落跳跃着陆 (DJL) 分析对于评估运动员的反应力和着陆机制至关重要.
了解外部干预措施 (如录音) 对DJL表现的影响,对于预防伤害和提高表现至关重要.

研究的目的:

为了研究不同的膝盖贴带条件在DJL期间对下肢动力学和动力学的影响.
确定动态磁带 (DT),刚性磁带 (RT) 和动态磁带 (KT) 与无磁带 (NT) 在影响反应强度和着陆力学方面相比如何.

主要方法:

21名运动员在四个条件下进行了40厘米的跳:没有磁带 (NT),动态磁带 (DT),刚性磁带 (RT) 和动态磁带 (KT).
测量了反应强度指数,包括地面接触时间 (GCT) 和反应强度指数 (RSI).
用SPM1d重复测量ANOVA分析生物力学数据,以确定显著差异 (p<0.05).

主要成果:

动力磁带 (KT) 在反应强度性能方面表现出最显著的改善.
KT的应用导致了最高的地面反应力 (GRF) 和最短的地面接触时间 (GCT),导致了最高的反应强度指数 (RSI).
在不同的磁带条件下,在脚和部旋转以及膝盖绑架和旋转方面观察到显著的运动变化.

结论:

膝盖贴带条件诱导了脚,膝盖和关节角度的轻微运动变化.
动力磁带 (KT) 似乎通过优化GRF和GCT来提高DJL期间的反应强度性能,从而有可能提高拉伸缩短周期 (SSC) 的效率.
对膝盖的KT应用可能会在落地跳跃着陆期间对运动员的反应力能力作出积极贡献.

Taping Over Different Ground Profiles

Taping Over Different Ground Profiles

Taping over varying ground profiles requires careful adaptation to achieve accurate measurements. On smooth, level ground with minimal vegetation, the tape can rest directly on the ground. Here, the taping team, typically consisting of a head and a rear tapeman, coordinates their positions with clear communication. The rear tapeman holds the tape at the starting point and guides the head tapeman toward a range pole placed beyond the endpoint, using hand or voice signals to ensure alignment.On...

Errors in Taping

Errors in Taping

Errors in taping arise from multiple factors that can significantly impact measurement accuracy in surveying. Misalignment of the tape, often due to human error, is one primary source. A skilled rear tapeman, using a telescope, can help correct alignment by guiding the head tapeman; however, human limitations still lead to small inaccuracies. These errors may include misplacement of pins or inaccurate tape readings due to common visual confusions, such as mistaking a six for a nine. Such...
