Gender differences in how technology is used to facilitate physical activity engagement was examined. 578 adults completed a survey assessing gender, mobile device usage, stages of change in physical activity based on the transtheoretical model of behaviour change (TTM) and relevant covariates. Data analysis revealed that both cumulative device types and cumulative reasons for using devices mediated gender differences in stage membership for physical activity. Females used fewer devices and reported fewer reasons for using such devices than male participants. These dispositions predicted a reduced probability of achieving action/maintenance stages for physical activity. Females used fewer mobile devices and perceived fewer incentives for using such devices. As a result they are less likely to enter the action/maintenance stages of physical activity. Interventions to promote female participation in physical activity need to recognise gender differences in the use of mobile technology
