Cross-sectional and longitudinal association of sports participation, media consumption and motor competence in youth.

Abstract

The beneficial associations of physical activity (PA) and sports with motor competence have been well documented. Similarly, high media time has been associated with poor motor competence. Limited information, however, is available on the combined effects of sport participation and media consumption on motor competence. The present study followed 213 Austrian middle-school students (57% male; age at baseline: 10.4±0.6years) over a 4-year period. Annual assessments included the German Motor Test 6-18, along with self-reported participation in club sports, time spent watching TV and using the computer. There were no interaction effects between sports participation and media time on motor competence. Club sports participation, however, was associated with higher motor competence, while there was an inverse association between media time and motor competence. Further, motor competence affected future participation in club sports while club sports had limited effects on subsequent motor development. High media time, on the other hand, impaired subsequent motor development, while effects of motor competence on media time were limited. Taken together, these results emphasize the importance of motor competence in the facilitation of sports participation during adolescence. Accordingly, a wide variety of movement experiences should be provided at young ages to promote motor development. In addition, the detrimental effects of media time on motor competence warrant that sedentary behaviors are targeted separately, particularly in youth not participating in sports.
