The Effect of Nordic Walking Intervention (NORDIN-JOY) on Individuals with Intellectual Disabilities and Their Families: A Multicenter Randomized Crossover Study.

Background: We aim to evaluate the effect of the Nordic Walking program on the quality of life and functionality of individuals with intellectual disabilities; Methods: The NORDIN-JOY study is designed as a multicenter, randomized crossover trial. Participants in the experimental group will engage in a Nordic Walking intervention, while those in the control group will participate in a Fit 5-Fitness Cards intervention. Both physical training programs will consist of two 60 min sessions per week over a three-month period. The study will assess measures of quality of life and physical fitness. Additionally, the feasibility and cost-effectiveness of both programs, as well as the average weekly physical activity levels during the six months following the intervention, will be evaluated; Results: The results of this study are anticipated to provide valuable insights into the effects of structured exercise interventions on individuals with intellectual disabilities. These findings will be disseminated through peer-reviewed journals and academic conferences; Conclusions: This protocol seeks to establish evidence on the impact of exercise programs in individuals with intellectual disabilities. The findings have the potential to inform specific recommendations for healthcare professionals, caregivers, and policymakers, promoting physical activity as a cost-effective strategy for improving care and quality of life in this population.
