甲乙組桌球選手競賽狀況能量消耗之比較研究

Abstract

目的：比較甲乙組桌球選手在模擬比賽中能量消耗、運動強度的差異及不同位置能量消耗之差異。方法：以甲乙組大學男性桌球校隊各10名為研究受試者，運用三軸加速規RT3配戴於腕、肘及腰部，監測20分鐘模擬比賽中的能量消耗及運動強度。所得資料以獨立樣本t考驗和混合設計二因子變異數分析，比較兩組間各變項之差異。結果：甲乙組能量消耗分別為134.74 ± 36.94 kcal與108.35 ± 33.61 kcal；運動強度則分別為5.85 ± 2.61METs與4.99 ± 2.4 METs。甲乙組選手能量消耗及運動強度皆未達顯著差異 (p > .05)。甲乙組選手中度及重度運動總時間沒有顯著差異，但輕度運動總時間，乙組9.6分鐘顯著高於甲組3.0分鐘( p< .05)。組別與不同部位之間無交互作用，兩組間能量消耗亦無顯著差果，但是組內不同部位達顯著，手腕部位的能量消耗顯著高於手肘與腰部 (p < 0.5)。結論：20分鐘模擬比賽中，不同技術水準之兩組桌球選手能量消耗及運動強度並無差異，但甲組選手輕度運動時間顯著少於乙組，手腕之能量消耗高於手肘及腰部。

Purpose: To compare the difference of energy expenditure, exercise intensity (METs), and the energy expenditure of different locations between A-level and B-level table tennis players in simulated matches. Methods: Ten A-level and ten B- level male university team table tennis players were recruited as the subjects. All subjects were asked to wear RT3 on the wrist, elbow and waist to measure energy expenditure and intensity during 20 minutes simulated matches. All collected data were analyzed with independent t-test and two-way ANOVA mixed design. Results: The energy expenditure of A-level and B-level players were 134.74 ± 36.94 kcal vs. 108.35 ± 33.61 kcal , respectively; and there was no significant difference between 2 groups (p>.05). The intensity of A-level (5.85 ± 2.61 METs) was not significantly higher than that of B-level group players (4.99 ± 2.4 METs) (p>.05). There was no significant interaction difference of energy expenditure between two independent variables, and no significant difference between 2 groups. However, there was a significant difference between the positions and found that the energy expenditure of wrist was significantly higher than that of elbow and waist (p<.05). The total time of high intensity and moderate intensity exercise between 2 groups were not significantly different. The time of light intensity of A-level players was significantly shorter than that of B-level players (p<.05). Conclusion: The energy expenditure and intensity were not different between two groups, the time of light intensity of A-level was shorter than that of B-level players during stimulated matches. The results showed the energy expenditure and intensity were not affected by different skill level. The energy expenditure of the wrist was higher than that of the elbow and the waist.
