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

本研究的主要目的是编制力量运用协调能力(TCAS)的测试，并检验其统计效度、信度、客观性和实用性。研究还考察了以下变量：用个人计算机系统测量和分析直到最大握力(Fmax)的握力消耗特性(GT)，GT与体格、身体素质和运动能力测试的关系，以及握力消耗的耐力(EG)。本研究的研究结果概括如下：(1)FMAX的A值具有较高的效度和信度。这与握力的集中发挥有一定关系。(2)握力(PG)的运用方式存在个体差异。(3)通过给出方向(一直施加到Fmax)来推断PG的不同。在不同的运动项目中，GT也不同。2.(4)斯梅德利弹簧动力…获得的握力有显著差异。没有发现多台测功机和一台数码显示测功机，两种测试之间的相关系数不是很高，但达到了显著水平。(5)GT与代表身体形态、身体素质和运动能力的变量相关不显著。3.(6)在FMAX中，EG的协调可以在50%或更小的范围内执行。它既可以估计需求与EG值之间的最大滞后，也可以估计滞后总和。4.(7)在个人计算机显示器上对3种描述形式(数字、条形图、波形图)进行TCAS。条形图和波形描述形式对0.3 Hz、0.1 Hz的正弦波分别进行30s左右的刺激是有效的。(8)跟踪是一种有效的方法，需求值范围为FMAX的5%~25%。(9)TCAS测量值的变化在三次试验中是稳定的。(10)本研究开发的TCAS(条形图和波形图)具有较高的效度、信度、客观性和实用性，是一种有效的测试工具。较少

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
