This study uses liliefors test techniques, homogeneity, and free sample t test. Based on the results of the study it can be concluded that there are differences in the speed of movement and explosive power of the arm muscles between the participants of the extracurricular activities of the Lawang SMAN basketball and SMAN 1 Singosari Malang Regency. This can be caused by several factors: (1) lack of frequency of practice, (2) physical exercise is rarely given (3) exercise is only extracurricular time. : Tujuan penelitian untuk mengetahui perbedaan kecepatan gerak dan daya ledak otot lengan antara peserta kegiatan ekstrakurikuler bolabasket SMAN 1 Lawang dan SMAN 1 Singosari Kabupaten Malang.
