The aim of the present study was to assess the effects of an 8-week structured recreational swimming program on health and functional parameters in 40–45-year-old subjects with Category 10 disability. Low-to-moderate intensity swimming exercises will be compared with characteristics and changes in body composition, cardiovascular function and respiratory efficiency. We used a pre-test and a post-test experimental design, participants swam three times per week. Physiological parameters were assessed before and after the intervention: body weight, body fat percentage, cardiac energy index, and forced expiratory volume (FEV1). The results indicated significant improvement (p < 0.05) in all indicators, which suggests that recreational swimming reduces fat, improves cardiovascular efficiency, and increases respiratory function. These results are consistent with prior research advocating for the inclusion of aquatic exercises as an alternative approach within rehabilitation programs for disabled people. The findings of the study indicate that swimming programs designed in the format of this study is a safe, effective and sustainable way of improving functional health in people with mobility impairments. Other studies should focus on a larger sample, on its long-term effects, and in the psychological and social benefits of swimming to provide a more complete view of its participation in adaptive rehabilitation.
