Background:
The distance between home and school is the most consistent predictor of active transport in youth: the closer an individual lives to school, the more likely they are to use active transport. While this suggests that it is preferable to live as close to school as possible, the limited physical activity accumulated during short trips may not offer substantial benefits to active transporters.
Methods:
The current study investigated the predicted physical activity benefits associated with a range of home-school distances in 595 young people aged 5 to 16 years (Years 1 to 11). Physical activity was measured using sealed pedometers over 7 days. Participants' home addresses and usual transport mode to and from school were collected via a questionnaire completed by parents (Years 1 to 6) and participants (Years 7 to 11).
Results:
A nonlinear relationship between predicted weekday activity and distance was detected, such that the high probability of active transport at short distances was offset by the low physical activity associated with walking short distances.
Conclusions:
A distance of approximately 2 km was associated with the best physical activity outcomes related to active transport (9% to 15% increase on weekdays). These findings have potential implications for future interventions and for planning residential developments or facilities.

Primary active transporters, like Na+, K+ and -ATPase, directly utilize ATP to move ions across the membrane. These transporters play significant roles in various physiological processes. For instance, Na+, K+ and -ATPase maintain...

Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
