| Summary: | 碩士 === 國立高雄師範大學 === 體育學系 === 106 === Objective: The purpose of the research was to analyze the efferts of unilateral and bilateral training on sport-related physical fitness of junior high school students.
Method: The participants of the experiment were thirty junior high school students who were randomly divided into the experimental group (unilateral and bilateral) and control group. Unilateral training group received only unilateral strength training while bilateral training group received traditional strength training twice a week for eight weeks. The control group simply maintain daily life and rest. All the participants of three groups were required to do the pre-test and post-test of maximum muscular strength, vertical jump, 40m sprints and T-test. Data were analyzed by mixed-designed two-way ANOVA. The significant level was set α=.05.
Result: After the unilateral and bilateral training for eight weeks, maximum muscular strength of the training groups increased better than control group (p<.05), and unilateral training group performed significantly better than the bilateral training group. There was no significant difference between the three groups in speed, agility and power (p>.05).
Conclusion: The eight weeks unilateral and bilateral training in maximum muscular strength of junior high school students had statistical significance. Furthermore, the unilateral training was better the bilateral training. But there was no significant difference in speed, agility and power.
