The purpose of this project was to investigate the effects of different goal setting techniques on physical fitness training performance and learning. Of particular interests examined by this study was testing reliability and generality of the interval goal setting model developed by O`Block and Evans in 1984. In experiment, 30 subjects performed the sit-up for one minute under three experimental conditions (interval goal setting, long term goal setting and no goal setting) for 12days of training phase. After training phase, a transfer phase for 3days was administered to all subjects in same conditions in order to examine practice effect resulted from the training period. The results showed that the goal setting groups performed and learned the musule endurance and the dynamic muscle strength training on sit-up performance better than no goal setting group. But no significant difference showed to performance in training and transfer phase between interval goal setting group and long-term goal setting group.
