概括

横向动态腿部压力装置 (HDLPD) 在腿部延伸过程中可靠地测量力-速度-功率变量. 这种设备提供比垂直跳跃测试更一致的结果来评估运动员的力量.

科学领域:

运动科学与生物力学
人类运动分析
强度和健康状况

背景情况:

精确评估力-速度-功率 (FVP) 特性对于优化运动表现和训练至关重要.
像垂直跳跃测试这样的传统方法在可靠地捕获FVP变量的全谱方面存在局限性.
水平动态腿部压力装置 (HDLPD) 为FVP评估提供了一个潜在的替代方案.

研究的目的:

为了比较HDLPD与垂直跳跃测试 (俯卧跳跃[SJ]和反移动跳跃[CMJ]) 衍生的FVP变量的会话内可靠性.
评估HDLPD在各种负载条件下测量最大腿部伸展性能的实用性.

主要方法:

这项研究涉及19名男子曲棍球运动员.
参与者在HDLPD上进行了最大的腿部延伸,重量从100%到200% (BW).
在没有负载,中度和高负载条件下进行SJ和CMJ测试 (22. 0 ± 4. 6公斤和43. 9 ± 9. 2公斤).

主要成果:

在所有FVP结果中,HDLPD的可靠性很高 (ICC=0. 8450. 974,CV=0. 434. 52%).
SJ和CMJ测试显示可接受的会话内可靠性,尽管一些变量具有较低的相对可靠性 (ICC = 0.5880.973,CV = 1. 19%8. 38%).
与垂直跳跃相比,HDLPD为某些FVP变量提供了更可靠的测量.

结论:

在最大腿部延伸的FVP变量评估中,HDLPD表现出极好的会话内可靠性.
对于寻求精确可靠的腿部伸展强度,速度和功率的从业者来说,HDLPD是一个有价值的工具.
这种装置提供了可靠的替代品或补充垂直跳跃评估的下部力量.

Power Expended by a Constant Force

Power Expended by a Constant Force

The relationship between work done and the time taken to do it can be explained using the concept of power. For example, several sprinters in a race may have the same velocity when they reach the finish line, therefore doing the same amount of work, but the winner does it in the least amount of time. Thus, power is defined as the rate of doing work. Since work can vary as a function of time, the average power is defined as the work done during a time interval, divided by the time interval.

Mechanical Efficiency of Real Machines

Mechanical Efficiency of Real Machines

The mechanical efficiency of a machine is a fundamental concept that describes how effectively a machine can convert input work into output work. According to this concept, the efficiency of a machine is equal to the ratio of the output work to the input work. An ideal machine, meaning a machine that has no energy losses, has an efficiency of one. This implies that the input work and the output work are equal.
However, in reality, no machine can be truly ideal, and all of them experience some...
