Abstract

Background
Physical activity is associated to several health benefits in children and has a tendency to track from childhood to adulthood. An adequate motor performance has been shown positively related to physical activity level in cross sectional studies and may be the foundation of a healthy lifestyle, but there is a lack of longitudinal studies. The objective of this study was to explore the longitudinal relationship between motor performance and physical activity in a three-year follow up study.
Methods
Longitudinal analyses were performed using data from the CHAMPS-Study DK, including 673 participants (44% boys, mean age 9.2 years old (SD=1.4)). Baseline motor performance tests consisted of vertical jump, shuttle run, handgrip strength, backward balance, precision throw and cardiovascular fitness. Composite Z-scores were generated to express health-related fitness and performance-related fitness. Physical activity was measured by accelerometer at baseline and three years follow up. Physical activity was expressed as percentage of time in moderate to vigorous physical activity level.
Results
Analyses showed significant positive associations between several baseline motor performance tests and three-year follow up measures. The Andersen test, vertical jump, health-related fitness and performance-related fitness showed significant positive associations to three years follow up measures of physical activity in both genders. Furthermore, shuttle run showed significant inverse associations to follow up physical activity for both genders. The analyses of the tests of cardio respiratory fitness and shuttle run were affected by interaction by gender resulting in significantly larger estimates for boys than for girls.
Discussion
Cardiorespiratory fitness, shuttle run, handgrip, vertical jump, health-related fitness and performance-related fitness were significantly associated to time spent at moderate to vigorous physical activity level at three years follow up. The clinical relevance of the results indicated cardiorespiratory fitness and shuttle run to be important skills to perceive in childhood as they affect the amount of physical activity in adolescence, especially in boys.
