摘要：Purpose: The aim of this study is to develop and produce an exercise model on butterfly stroke swimming skill for athletes aged 11-13 years. Methods: The method used in this study refers to the model development method or Research and Development (R&D) based on the 10 steps of development proposed by Borg and Gall. Result: The percentage of the results of trial on small group is 82.06% while the percentage of the results of trial on large group is 84.35%. The results of the study, obtained through the effectiveness test, found t-calculate 16.66 > t-table 2.02 in the experimental group and tcalculate 9.996 > t-table 2.02 in the control group. Conclusion: Thus, the study concluded that there is the effectiveness of the results on butterfly stroke swimming skill for athletes in the age group of 11-13 years by the use of drill-based exercise through the android app.
