摘要
由於生活型態的改變，坐式生活者增加，導致流行病罹患率的增加。集中式運動可以改善心肺適能並促進健康，分散式運動也有助於中老年人及坐式生活者提升心肺適能，但對於年輕族群的效果仍需進一步加以探討。本研究目的即在探討集中式與分散式跑步運動對青少年心肺適能之影響。本研究以30名男性青少年(平均年齡為13.6±0.5歲，平均最大攝氧量為47.13±7.24ml/kg/min)作為受試對象，以配對分組方式分為集中式跑步運動組、分散式跑步運動組及控制組。集中式運動組除每週2次體育課外，額外進行每週3天、每次連續30分、強度為70%VO2R的跑步運動，分散式運動組則除體育課外，進行每週3天，每個運動天分為早晚2次15分鐘、強度為70%VO2R的跑步運動，控制組除體育課外，不從事任何運動。八週運動前後皆進行最大攝氧量及身體組成之評估，所得資料則以混合二因子變異數進行分析。結果發現：一、最大運動時，運動兩組的最大攝氧量及運動測驗持續時間均有顯著提升(p<.05)，而最大換氣量在三組中均顯著增加(p<.05)，三組最大心跳率則無任何改變。二、非最大運動時，運動組之換氣當量、呼吸交換率及心跳率均顯著下降(P<.05)，控制組則只有呼吸交換率有變化(p<.05)。三、安靜狀態下，運動組之心跳率均顯著降低(p<.05)，控制組則無任何改變。四、身體組成中，肌肉量均有顯著增加(p<.05)，但體脂肪百分比只有集中運動組有顯著降低(p<.05)，體重的部分三組均無任何變化。經過討論之後，本研究得到以下結論:以八週時間從事每週3天、每天30分鐘強度為70%VO2R之跑步運動，不論是以集中方式或分散方式來加以進行，均能有效改善青少年之心肺適能。
關鍵詞：集中式運動、分散式運動、青少年、心肺適能。

Abstract
Purpose: The purpose of this study was to examine the effects of eight-week continuous and discontinuous running exercise on cardiorespiratory fitness in adolescents. Method: Thirty adolescents (age=13.6±0.51 yrs, VO2max=47.13±7.24 ml/kg/min) were recruited as the subjects for this study. They were divided into three different groups according to VO2max values: continuous exercise group (CEG), discontinuous exercise group (DEG) and control group (CG). The CEG performed single bout of running lasting for 30 minutes at 70% VO2R (three times/week, 8weeks). DEG performed two bouts of running lasting for 15 minutes at 70% VO2R (three times/week, 8weeks). Their VO2max and body composition were measured after 8weeks. Data were analyzed by using mixed design two-way ANOVA. Results: 1) Maximal data: both CEG and DEG improved in VO2max, and treadmill running performance (p<.05). All of the three groups had significant increase in VEmax, but there is no difference in HRmax. 2) Submaximal data: VE/VO2, RER, and HRsub were all improved in CEG and DEG (p<.05), but there is no difference in CG. 3) Rest data： HRrest was decreased in CEG and DEG (p<.05) , but there is no difference is shown in CG. 4) Body composition: muscle mass all increased in three groups, but percent body fat only decrease in CEG, and there is no different in body weight. Conclusions: continuous and discontinuous running exercise has the same effects improving cardiorespiratory fitness in adolescents.
Key words: continuous exercise, discontinuous exercise, adolescents, cardiorespiratory fitness
