Research on Strength-exertion Co-ordination ability for human.

本研究的主要目的是发展一个评估力量运用协调能力的测验（TCAS），并检验其统计学效度、信度、客观性和实用性。本研究亦探讨以下变数：握力运用特质（GT）至最大握力（Fmax）之个人电脑系统量测与分析，GT与体格、体能、运动能力测验之关系，以及握力运用耐力（EG）。本研究的主要结果如下：1. (1)A Fmax值具有较高的效度和信度。这与握力集中用力有关。（2）握力的用力方式存在个体差异。(3)PG通过给出方向（施加直到拉伸时的Fmax）推断不同。GT在不同的运动项目中也存在差异。2.（4）Smedley弹簧力法测得的握力与正常人的握力相比有显著性差异（P <0.05）。 关于我们 未发现数字显示测功仪和数显测功仪试验，两者相关系数不高，但有显著性。(5)GT与代表体格、身体素质和运动能力的变量无显著相关性。3.（6）EG的协调可以在Fmax的50%或更小的范围内执行。它可以估计需求和EG值之间的最大滞后和滞后总和。4.（7）在微机显示屏上对3种描述形式（数字、条形图、波形）进行TCAS。以0.3Hz、0.1Hz的正弦波波形分别进行约30秒的条形图和波形描述形式是有效的。（8）在需求值为Fmax的5%~ 25%的范围内，跟踪是一种有效的方法。（9）TCAS测量值在三次试验内变化稳定。（10）本研究开发的TCAS（条形图和波形图）具有较高的信度、效度、客观性和实用性，是一种有效的测验工具。少

The main purposes of this study were to develop a test for estimating the co-ordination ability of strength exertion (TCAS) and to examine its statistical validity, reliability, objectivity, and practicability. The following variables were also examined : the grip strength exertion traits (GT) until maximal grip strength (Fmax) measured and analyzed by a personal computer system, the relationships between GT and physique, physical fitness and motor ability tests, and the endurance of grip strength exertion (EG). The findings in this study can be summarized as follows: 1.(1)A value of Fmax has relatively high validity and reliability. It has some relation with grip strength concentrated exertion. (2)Individual variations for the exertion pattern of grip strength (PG) existed. (3)PG was inferred to differ by giving direction (exerted until Fmax at a stretch). GT was also differ in various athletic events. 2.(4)Significant differences between grip strength obtained by Smedley spring dynam … More ometer and a digital displayed dynamometer tests were not found and the correlation coefficient between both tests was not so high, but significant. (5)GT showed insignificant correlations with variables representing physique, physical fitness, and motor ability. 3.(6)Co-ordination by EG can enforce with the range of 50% or less in Fmax. It can estimate both a maximal lag and the sum total of lag between the demand and EG value. 4.(7)TCAS was performed for 3 kinds of description forms (number, bar chart, wave) on display of personal computer. Bar chart and wave description forms were effective with 0.3Hz, 0.1Hz of sinusoidal wave form performed for about 30 seconds respectively. (8)Tracking was an effective method with the range of demand value of from 5% to 25% of Fmax. (9)The change of TCAS measurement value is stable within three trials. (10)It seems that TCAS (bar chart and wave) developed in this study was effective tests because they show relatively high validity, reliability, objectivity, and practicability. Less
