Circuit training improved physiological conditions in wheelchair basketball players. The study involved 36 male wheelchair basketball athletes with spinal cord injuries aged 19–26 years, divided into an experimental group (EG, n=18) undergoing circuit training and a control group (CG, n=18) performing aerobic upper-body exercises. Anthropometric measurements and the 12-minute wheelchair propulsion distance test, which assesses maximal oxygen uptake (VO2 max), were conducted at baseline and post-intervention. The results showed a significant improvement in the EG for the 12-minute propulsion distance (p<0.001), while no significant changes were observed in the CG. The EG also showed significant improvements in handgrip strength and BMI. Circuit training enhanced cardiorespiratory fitness, musculoskeletal strength, and BMI in wheelchair basketball players. The study suggests that incorporating circuit training into daily training regimens can have a substantial positive impact on the physical fitness of wheelchair basketball players. The findings align with existing literature indicating that circuit training is effective in improving cardiorespiratory fitness compared to other resistance training modalities. The study had limitations, including a small sample size and reliance on a single test for cardiopulmonary endurance. Future research should consider larger samples, longer durations, and additional measures such as oxygen consumption. The results highlight the potential of circuit training for improving physical fitness in wheelchair basketball players and individuals with spinal cord injuries.Circuit training improved physiological conditions in wheelchair basketball players.
