青少年捷泳耐乳酸訓練篩選模式之建構

本研究主要目的在於結合皮爾遜積差相關、迴歸分析及區別分析的統計方法，建構捷泳耐乳酸訓練篩選模式，以提升捷泳耐乳酸訓練之效果。本研究對象為台中巿培訓選手40名，己受過二年以上持續練習之國中和高中學生。以實驗法測出受試者各能力指標，然後將各資料以SPSS FOR WINDOWS10.0處理。本研究結果有以下三點：

一、在全體青少年、不同性別和不同年齡方面，其血乳酸值、划幅、100公尺捷泳划手成績、100公尺捷泳踢水成績等要素均與100公尺捷泳成績有相關性，而划頻必須和划幅相互作用才與100公尺捷泳成績有相關性。

二、划幅和划頻;100公尺捷泳划手成績;100公尺捷泳划手成績與血乳酸值;100公尺捷泳划手成績、血乳酸值和100公尺捷泳踢水成績等要素可預測100公尺捷泳成績。

三、利用血乳酸值、划幅、划頻、100公尺捷泳划手成績和100公尺捷泳踢水成績可建構出青少年捷泳耐乳酸訓練篩選模式。

The objective of the study was to construct a screening model of freestyle swimming lactate tolerance training by integrating Pearson product-moment correlation, Multivariate Analysis, such as regression analysis, and discriminant analysis, in order to improve the screening accuracy of freestyle lactate tolerance training. The subjects were 40 training athletes from Taichung City, who were middle school and high school students that have received two years of continuous training. Experiments were conducted to test the competency indices of the subjects. The data were analyzed with SPSS FOR WINDOWS10.0. The results were as follows:

1. Adolescence of different genders and ages showed correlation in the blood lactate, stroke length, 100m freestyle swimming crawl performance, 100m freestyle swimming kicking performance with 100m freestyle swimming performance, and the mutual effect of the frequency and length of strokes was correlated with the 100m freestyle swimming performance.

2. The frequency and length of strokes ; 100m freestyle swimming crawl performance ; 100m freestyle swimming crawl performance and blood lactate ; 100m freestyle swimming crawl performance, blood lactate and 100m freestyle swimming kicking performance could predict the 100m freestyle swimming performance.

3. Use of the blood lactate level, stroke length, stroke frequency, 100m freestyle swimming crawl performance, 100m freestyle swimming kicking performance, and 100m freestyle swimming performance could construct the screening model of freestyle swimming lactate tolerance training for adolescence.
