[Motor competence and quality of life in elderly active persons].

Physical activity is a vital pre-condition for healthy aging and well-being. While the association between objective and subjective health in old age has extensively been investigated, the relationship between objective motor competence-the capability of mastering motor demands in everyday life adequately by using motor resources optimally-and subjective health-related quality of life has not been studied yet. In an interdisciplinary study, 168 active seniors (36 men) at the mean age of 67 (range: 59-89) underwent a test battery assessing motor resources and two objective domains of everyday life motor competence-"Perceiving and Reacting" and "Mastering Complex Situations". Subsequently, participants rated their mental, physical, social, functional health and life satisfaction by questionnaire. Motor competence domains were age-dependent; the strongest decrease was found for "Mastering Complex Situations". Only "Mastering Complex Situations" was predicted by motor resources: competent seniors in this domain were faster in motor activity, simple reactions, body movements following acoustic and optic signals, and showed a stronger handcraft and a higher mobility. Overall, health-related quality of life was contingent upon motor competence: physical and functional health and-to a lesser extent-mental health and life satisfaction showed a systematic but moderate relationship to both motor competence domains. The results emphasize the significance of age-compatible and everyday life-adjusted physical activity for the well-being of elderly persons. Even active elderly persons show deficits in motor competence and should be trained, taking into account individual resources and flaws.
