Pre-schoolers fundamental movement skills predict BMI, physical activity, and sedentary behavior: A longitudinal study

Aims: This study aimed to predict the variation in future fundamental movement skills (FMS), physical activity (PA) and body mass index (BMI) from prior FMS, PA, and BMI in British pre-schoolers. Methods: British pre-schoolers (n = 177) underwent assessment of FMS, via the Test of Gross Motor Development 2 (TGMD-2), BMI, and PA, via accelerometer at two time points one year apart. Regression analysis was used to predict the change in PA and BMI in Year 2 from FMS variables in Year 1 and Year 2. Results: Variation in FMS performance between individuals predicted a significant amount of change in BMI, with 12.3 and 9.8% of the change in Year 2 BMI data explained by change in Year 1 and Year 2 FMS data, respectively. Change in FMS performance between individuals predicted a significant amount of change in PA, but was better at predicting change in sedentary activity rather than light or moderate-vigorous activities. A combination of run, throw, dribble, and kick performance predicted 46.1% of the change in sedentary activity between individuals in the 2nd year of testing. Conclusions: FMS mastery at four years of age predicts children's BMI and time spent sedentary at five years of age.
