Abstract

The development research aims to produce an exercise model on butterfly swimming for athletes in the age group of 11-13 years. This research applies Research and Development (R & D) method. The testing of the exercise model was conducted to 20 athletes, testing for large group to 60 athletes, and effectiveness test to 40 athletes. The effectiveness test of the development model of butterfly stroke swimming found that t-calculate (16.66) > t-table (2.02) and Ha is accepted. It means that the new exercise model of butterfly stroke swimming is better than the old one. Based on the research findings, it is concluded that the exercise model of butterfly stroke swimming can enhance butterfly stroke swimming skill of athletes in the age group of 11-13 years, this exercise model of butterfly stroke swimming is more effective and efficient; therefore, the athletes are interested in and motivated to practice swimming in the butterfly stroke.
