The study, published in the International Journal of Epidemiology, examined the relationship between physical activity, from childhood to adolescence, and lung function in adolescence in 2,300 boys and girls participating in the Avon Longitudinal Study of Parents and Children (ALSPAC), a United Kingdom-based birth cohort also known as "Children of the 90s."
The children's physical activity was recorded using an Actigraph sensor over seven-day periods at 11, 13 and 15 years of age and their lung function was analysed by spirometry at 8 and 15 years of age. The children's parents also completed questionnaires on sociodemographic, psychological and lifestyle-related factors.
Researchers - Physical-activity - Trajectories - Girls - Physical-activity
The researchers defined three physical-activity trajectories: low, moderate and high. "Girls in the moderate and high physical-activity trajectories had a higher exhalation capacity -- that is, greater forced expiratory volume -- than girls in the low physical-activity trajectory," explained lead author Célina Roda.
In contrast, no such association was observed in boys. One possible explanation, according to Roda, is that "growth spurts occur earlier in girls than in boys, so any effect of physical activity on...
