Effects of an Alternative Sports Program Using Kin-Ball in Individuals with Intellectual Disabilities

Abstract

The first aim of the present work was to examine the effects of a physical activity sports program, specifically Kin-Ball, within a group of individuals with intellectual disabilities, on decreasing sedentary behavior and improving basic physical skills. The second aimwas to evaluate social validity and acceptability of the intervention. In this pre-experimental study, 47 individuals participated (46.8% male and 53.2% female) with an average age of 29.85 (SD = 10.41). All participants were administered an intervention programbased on the alternative sport of Kin-Ball. BMIwas calculated for body composition and age-related Z-scoreswere interpretedwith the tables provided by theWHO. Endurancewasmeasured through a modified six-minute test, speed was analyzed using a 50 m test, and strength was estimated according to a hand-grip dynamometer. Likewise, balance and coordination were examined in line with adaptations proposed by the scientific literature. Results indicated that all cases experienced statistically significant differences following the intervention program (p = 0.000). Improvement effects were detected in all post-intervention tests (endurance, strength, speed, balance, and coordination). As amain conclusion, it is indicated that an alternative sports-based program improves physical ability and motor skills in individuals with intellectual disabilities.
