High-Intensity Interval Training (HIIT) was evaluated in a pilot study to assess its impact on cardiorespiratory fitness, musculoskeletal strength, and agility in wheelchair tennis players with spinal cord injuries. Thirty participants, aged 19-28, were divided into an experimental group (n=15) and a control group (n=15). The experimental group underwent a 16-week HIIT program, while the control group followed a standard training regimen. Anthropometric assessments, the wheelchair yo-yo test, and hand grip evaluation were conducted before and after the intervention. Results showed significant improvements in the experimental group for the yo-yo test and hand grip evaluation (p < 0.001), with no significant changes in the control group. The study concluded that HIIT significantly enhances cardiorespiratory fitness, musculoskeletal strength, and agility in wheelchair tennis players. The findings suggest that incorporating HIIT into training regimens can improve physical performance and overall quality of life for individuals with spinal cord injuries. The study highlights the importance of tailored training programs for athletes with disabilities, emphasizing the need for further research to explore long-term effects and broader applications.High-Intensity Interval Training (HIIT) was evaluated in a pilot study to assess its impact on cardiorespiratory fitness, musculoskeletal strength, and agility in wheelchair tennis players with spinal cord injuries.
