Relationship between quality of life and physical fitness in adults with intellectual disabilities

Purpose People with intellectual disabilities have lower levels of physical fitness compared with peers without intellectual disability, because of the high levels of sedentary behaviour in this population. This study aims to know the relationship between quality of life and physical fitness in adults with intellectual disability. Design/methodology/approach Ninety-six adults with intellectual disability were assessed with quality of life questionnaire and physical fitness tests, which involve balance, muscle strength, flexibility and aerobic condition. Findings Adults with higher self-reported levels of quality of life reported higher levels of physical fitness in balance, muscular strength and flexibility. In contrast, in aerobic condition were not found significant correlations with self-reported quality of life. Originality/value These findings support the hypothesis that people with intellectual disability with lower levels of physical fitness could influence in their levels of quality of life. This insight is useful for improving treatments to improve physical fitness in this population.
