Procedure.
Preparation of participants
All potential participants will be instructed to wear the pedometer on the waistband of their clothing for seven days, based on previous study protocols [96-99] in order to establish baseline step-counts during normal daily activity. Tudor-Locke and Bassett [52] have classified pedometer-determined PA in adults by an average step count of less than 5,000 steps/day as a sedentary lifestyle, and 5,000 to 7,499 steps per day as low activity; therefore, participants who accumulate an average baseline step count of 7,500 steps per day or more will be excluded; remaining participants will be randomized to one of the two groups. Baseline outcomes measures were collected during the seven days pedometer assessment including the primary and secondary outcomes. After randomization, all participants will attend a 30 minute education session on the health benefits of being physically active, then participants in the walking group will receive a brief intervention group session of up to 70 minutes, including a 10 minute self-efficacy walk, a 30 minute session focussing on physical activity behaviour change, and 30 minutes focused on the education resource material (physical activity and PA booklet). This intervention session will be based on the Back2Activity protocols [100] and conducted by physiotherapists (including one with training in motivational interviewing), and student researcher.
