BACKGROUND: Physical activity levels of cardiac rehabilitation attendees with coronary heart disease (CHD) are low. This study examined whether frequency of physical activity measurement (Measure It!; self-report and step-tracker daily steps; <5 min) influenced ActiGraph accelerometer-measured physical activity in insufficiently active cardiac rehabilitation attendees with CHD. METHODS: This two-arm multicentre randomised trial with concealed allocation and blinded assessments included cardiac rehabilitation attendees (n = 190) randomised to either 2 or 5-physical activity measurements (2-PAM or 5-PAM) over 24-weeks. The primary outcome was daily minutes of moderate-to-vigorous physical activity (MVPA; accelerometry). Secondary outcomes included daily steps (accelerometry), body-mass-index, waist circumference and quality-of-life (AQoL-6D). RESULTS: Adjusted point estimates of effect for change in MVPA (Cohen's f = 0.05) and daily steps (Cohen's f = 0.14) were higher at 24-weeks for the 5-PAM group than 2-PAM group but did not reach a-priori statistical significance at this small-medium effect size. For daily steps (difference-in-difference 447 steps/day, 95% CI: -44-to-938, p = 0.075) the observed effect may be considered a clinically meaningful margin. Quality-of-life significantly improved within groups over time (p < 0.001). Most participants received the Measure It! intervention as intended (2-PAM 2-measures: 76% (n = 71/94); 5-PAM ≥4-measures: 92% (n = 87/95)). CONCLUSI...
