中文摘要 | 本研究以修平技術學院擊劍代表隊7名選手為受試者,包括4名男選手和3名女選手。本研究主要目的,以不同握把角度檢測不同肌肉的疲勞性以及實驗前後握力的差異性,並以集郡分析探討受試者肌肉的特質,做為教練訓練的參考。實驗擷的肌電訊號以均方根、中位頻和高低頻,經處理後,再以SPSS統計軟體進行ANOVA、t檢定、相關等分析不同握把角度肌肉的疲勞差異性。最後再以21°握把角度的原始均方根進行集群分析,檢驗選手肌肉特性的集群分組,提供教練在訓練上的參考。本研究結果如下: 一、 握把不同角度的均方根、中位頻和高低頻的疲勞性分析未達顯著水準。 二、 握力差的實驗中21°、24°、18°達到顯著差異,21°劍身握把角度對其它握把角度的疲春性達顯著差異。 21°握把的均方根集群分析結果,在三個集群中,第一集群,特性為握力佳,較不易疲勞,其中觀察值5為唯一女劍手,集群分析結果與受試選手在平時訓練與特性表現大致相符,肌電訊號的疲勞性檢驗加上集群分析方法可做為選手特質集群使用工具。 |
英文摘要 | This research involved performing tests on seven fencers from the fencing team of the Hsiuping Institute of Technology. The test, which were conducted on four male fencers and three female fencers, were designed to assess how the angle of the handle of a foil determines muscular fatigue. In this experiment, After their retrieval, the EMG were processed with AcqKnowledge (version 3.72) produced by BioPAC to figure out their root mean square, median power frequency and the ratio of high-low frequency. Muscular fatigue was evaluated by means of the primitive root mean square, the median power frequency spectrum displacement, the high-low ratio horizontal shift ratio and grip difference. Discrepancy in muscular fatigue that arises from different angles of grip was analyzed with ANOVA, T-test and correlation test, using statistical software of SPSS. Finally, with the primitive root mean square of a grip angle of 21°, we performed cluster analysis to test the grouping of the fencers' muscular features, so that the findings will be useful to coaches in training their fencers. The findings of this research are as follows: 1. It is found that there was not any marked discrepancy in muscular fatigue with respect to the root mean square, the median power frequency and the high-low ratio frequency of different angles of grip. 2. As regards the experiment of grip difference, there was a marked discrepancy among grip angles of 21°, 24° and 18°. There was a marked difference between the muscular fatigue related to a grip angle of 21° and that related to other grip angles. According to the findings of the cluster analysis of the root mean square of a handle angle 21°, among the three groups, the first group was characterized by a good grip and less fatigue, wherein the observation value 5 denotes the only female fencer. The findings of cluster analysis roughly conformed to the performance of the test recipient fencers during training and their characteristics. The findings indicate that, the fatigue test conducted by means of EMG, coupled with cluster analysis, can function as a fencer's feature group usage tool. |
