Are early blooming teenagers at risk of low physical activity?
We did a systematic review of published literature that examined the relationship between maturational timing (early, average or late maturing), physical activity and sedentary behaviour in boys and girls.
The review offered modest evidence that early maturing boys and girls were more at risk for inactivity and higher amounts of sitting overall. However, the evidence was quite inconsistent especially for sub-sets of physical activity including sports participation and active transport.
The inconsistency in the findings across the evidence base shows that the association between biological maturity status and physical activity is likely complex and quite individual.
More qualitative research is required to gain a better theoretical understanding of how the timing of biological maturity may influence physical activity and sedentary behaviour in boys and girls.
