The Despite the established positive relationships between public transport and physical activity [Self-reported transport-related physical activity (min/week and MET-min/week) increased among intervention participants by 133.3% while transport-related physical activity of the control group decreased from baseline to follow-up. The differences in self-reported transport-related physical activity (non-significant) between control and intervention group participants may be attributed to the greater number of public transport trips undertaken as a result of the intervention, as commutes between bus stops and destinations constitute transport-related physical activity. In line with the hypothesised dual-process theory mechanism, findings of increased transport-related physical activity performance mirror Cleland et al.’s [The self-reported total physical activity levels of the control group increased in both the min/week and MET-min/week undertaken. While a small increase in MET-min/week of total physical activity was reported among the intervention group, a decrease in min/week total physical activity was observed. The intervention group’s increase in transport-related physical activity and relatively unaltered total physical activity suggests the potential for a compensatory mechanism. These patterns are similar to those of the While some studies provide evidence of both individual short-term and population-wide secular compensatory mechanisms between physical activity domains [
