| Summary: | 碩士 === 國立體育大學 === 教練研究所 === 97 === Purpose: To compare the effect of high-intensity interval training (HIT) and moderate-intensity continued training (MCT) by canoe ergometer on aerobic capacity and exercise performance in canoeists. Methods: Twenty-four national canoeists (age: 18.4 ± 1.9 yrs, height: 172.4 ± 7.7 cm, weight: 70.3 ± 9.8 kg) participated to this study. All subjects completed the graded exercise test (GXT) on canoe ergometer to measure the VO2peak, anaerobic threshold (AT), heart rate (HR) and the time of exhaustion on pre-, mid- and posttraining. Pre- and posttraining, time trial of 1000 m, 500 m and 200 m on canoe ergometer were performed. Subjects were divided into three groups of high-intensity training (HIT) group, moderate-intensity continued training (MCT) group and traditional training (TDT) group according to the performance of 1000 m time trial. The training program proceed 3 times per week for 4 weeks. HIT group included 7 repeated of 2-min intervals training at power of 90% VO2peak and separated by 1 minute rest. MCT group performed continuous training at power of 65% VO2peak for 20 min. TDT group performed a traditional endurance training in low-intensity for 90 min. One-way ANOVA with repeated-measures were used to compare the VO2peak, AT and HR at pre-, mid- and posttraining within groups. Paired t – test were used to compared the performance of 1000 m, 500 m and 200 m at pre- and posttraining. All variables at mid - and posttraining among groups were compared by ANCOVA with covariate of variables at pretraining. Result: The VO2peak in HIT and MCT groups significantly increased after 2 weeks training (p<0.05). AT in MCT group significant higher than in TDT group, after 4 weeks training, HR in MCT group significant lower than HIT and TDT groups (p<0.05) at the intensity of 75 W in GXT. The performance of 1000 m significant improvement in three groups, time trial of 500 m had significant improved in MCT and TDT groups. However, performance of 200 m improved only in HIT group (p<0.05). Conclusions: high-intensity interval training and moderate-intensity continued training by canoe ergometer results in greater efficiency and improvement than traditional training. Moderate-intensity continued training had a better improvement in aerobic capacity and performance of 1000 m and 500 m. However, high-intensity interval training is a better way for improve the performance of 200 m on canoe.
