Background and Study Aim. Basketball involves skills that must be applied dynamically, explosively and repeatedly. Players must be able to speed up and slow down with control, especially when dribbling, shooting or bouncing the ball. The purpose of the study was to test a circuit training-based physical condition training model to increase speed, agility, arm power, and leg muscle power for basketball athletes. Materials and Methods. This type of research is an experiment with two groups, namely the experimental group (n = 28) and the control group (n = 28). The samples were male athletes aged 15-18 years. Subjects had participated in competitions and all players were healthy with no history of illness or injury reported in the previous 3 months. The instruments were 20-meter running test speed, agility (Illinois Test with Dribbling the Ball), arm power (MEDBALL), and leg power (Counter Movement Jump Test). The data analysis technique was a t-test. Results. The results of the study can be concluded that the circuit training-based physical condition training model consisting of 6 posts, is effective for increasing speed (0.017 < 0.05), agility (0.000 < 0.05), arm power (0.000 < 0.05), and leg muscle power (0.036 < 0.05) of basketball athletes. We recommend that basketball coaches consider incorporating a circuit training-based physical condition training model in training, as a simple and practical model to improve athletes' physical condition. Conclusions. We recommend that basketball coaches consider including a circuit training-based physical condition training model in training, as a simple and practical model for improving athletes' physical condition. For researchers who intend to continue or replicate this study, it is recommended to conduct tighter control in the entire series of experiments.
