Overall , toddlers tend to exceed the total PA recommendation of 180 min/day ; however , very little of this time is spent at higher movement intensities .
Even with high PA rates , toddlers still engage in substantial ST .
Early experiences in physical activity ( PA ) are important to shape healthy movement behaviours long-term ; as such , it is critical that PA is promoted from infancy , and that detrimental behaviours ( e.g. , prolonged sedentary time [ ST ] ) are minimized .
The purpose of this systematic review and meta- analysis was to examine infants ’ and toddlers ’ movement behaviours across daytime hours .
Physical activity and objectively assessed sleep in 6‐month‐old infants in Taiwan
Adequate physical activity is associated with improved sleep in adults . Such associations , however , vary greatly across studies in pediatric population s , with no studies involving infants found in the literature . This prospect i ve observational study was design ed , therefore , to examine the association between physical activity and  sleep patterns in infants . A total of 183 healthy infants aged 6 months wore an actigraph for 7 days to measure physical activity and sleep .  Parents and caregivers completed a  sleep-activity diary  over the same period documenting the different types of infant activities . Daily mean time spent in  screen-time-or-limited physical activity , including screen-based ( e.g. , watching television or other electronic devices ) and non-screen based activity ( e.g. , quiet play or restricted infant movement when carried by caregivers or seated in high chairs , swings , or bouncer seats ) , was 6.68 hr ( SD = 1.99 ) , which represented 47.50 % of daytime waking hours ( SD = 13.73 ) . We found that 65 ( 35.5 % ) infants engaged in some screen time during the study , with 10 ( 5.5 % ) infants having an average daily screen time > 30 min . In our multivariate linear regression model , more hours of screen-time-or-limited physical activity per day were significantly associated with a decrease in total daily 24 hr sleep duration ( p < 0.01 ) . Findings from our study suggest that reducing screen-time-or-limited physical activity might be an approach for promoting adequate sleep and lengthening infant daily sleep duration
