INTRODUCTION: Individuals with @entity6926 ( @entity6926 ) type I often show @entity425 . However, it is unclear whether @entity425 is a consequence of physical inactivity or a result of the disease itself. The aim was to assess muscle function in youth with @entity69642 and evaluate physical activity (PA). METHODS: Fourteen @entity1 with OI type I (mean age [SD]: 12.75 [4.62] years) were compared to 14 age- and gender-matched controls (mean age [SD]: 12.75 [4.59] years). Muscle force and power were determined through mechanography. PA and daily energy expenditure were measured with an accelerometer and a questionnaire. RESULTS: Compared to controls, @entity1 with OI type I had lower muscle force and power. OI type I @entity1 were as active as their healthy counterparts. CONCLUSIONS: @entity1 and adolescents with @entity69642 and their healthy counterparts did not reached daily recommendations of PA. Given their muscle function deficit, youth with OI type I would benefit to reach these recommendations to prevent precocious effect of aging on muscles.
