Effects of a Progressive Adapted Physical Education Program on Muscular Strength and Endurance in Adolescents With Mild Intellectual Disability

This randomized controlled trial investigated the effects of a 10-week progressive adapted physical education program on muscular strength and muscular endurance in adolescents with mild intellectual disability. Physical inactivity and reduced physical fitness are common among adolescents with intellectual disabilities and may negatively affect functional independence, health, and quality of life. Participants were randomly assigned to either an intervention group or a control group. The intervention group participated in a structured adapted physical education program in addition to their regular school activities, while the control group continued their usual curriculum without additional exercise intervention. The program was implemented progressively over 10 weeks and included activities designed to improve upper-body strength, lower-body strength, core endurance, and overall muscular fitness. Before and after the intervention period, participants completed physical fitness assessments evaluating muscular strength and endurance. The aim of this study was to determine whether a progressive adapted physical education program could improve physical fitness outcomes in adolescents with mild intellectual disability.
