摘要

Objective: To investigate the effect of a school-based intervention called Travelling Green (TG) on children's walking to and from school and total daily physical activity. Method: A quasi-experiment with 166 Scottish children (8-9. years) was conducted in 2009. One group (n= 79) received TG and another group (n= 87) acted as a comparison. The intervention lasted 6. weeks and consisted of educational lessons and goal-setting tasks. Steps and MVPA (daily, a.m. commute, p.m. commute, and total commute) were measured for 5. days pre- and post-intervention using accelerometers. Results: Mean steps (daily, a.m., p.m., and total commute) decreased from pre- to post-intervention in both groups (TG by 901, 49, 222, and 271. steps/day and comparison by 2528, 205, 120, and 325. steps/day, respectively). No significant group by time interactions were found for a.m., p.m., and total commuting steps. A medium (partial eta squared = 0.09) and significant (p< 0.05) group by time interaction was found for total daily steps. MVPA results were similar to step results. Conclusions: TG has a little effect on walking to and from school. However, for total daily steps and daily MVPA, TG results in a smaller seasonal decrease than for children who do not receive the intervention.
