Sedentary patterns, physical activity and health-related physical fitness in youth: a cross-sectional study

International Journal of Behavioral Nutrition and Physical Activity, 2017
BackgroundStrong evidence indicates that moderate-vigorous physical activity (MVPA) is positively associated with fitness in youth, independent of total sedentary-time. Sedentary-time appears negatively associated with fitness only when it replaces MVPA.
