[[abstract]]Effects of Eight-week Continuous and Discontinuous Running Exercise on Cardiorespiratory Fitness in Adolescents July 2004 Student: Yi-chia Wu Advisor: Jiunn-chern Jwo 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
