Background: Physical inactivity and sedentary behavior (SB) are independent risk factors for all-cause mortality in healthy adults and in those with cardiovascular disease. Yet, there are very few studies that have investigated how much physical activity (PA) and SB our cardiac rehabilitation (CR) patients are doing, particularly objectively.
Purpose: The aim of this study was to objectively assess PA and SB of CR participants over 12-months to determine if they were meeting the recommended public health PA guidelines.
Methods: Seventy-two CR participants, age = 64.2 ± 9.6 y (mean ± standard deviation; 79% male), wore an ActiGraph ActiSleep accelerometer for 7-consecutive days at baseline, 6-weeks, 6 and 12-months to assess daily minutes of moderate-to-vigorous PA (MVPA) and SB ( 100 counts/min). Other outcomes collected were self-reported MVPA and SB, body mass index, waist-to-hip ratio, lipid profile, blood glucose level, quality-of-life, exercise capacity, anxiety and depression.
Results: During the 6-week CR program participants increased their light PA (p 0.01) and this was maintained up to 1-year. SB and MVPA did not change during the 6-week CR program but did improve over 6-months (SB decreased (p 0.001), MVPA increased (p 0.05)), which was maintained up to 1-year. Completion of MVPA in 10 minute bouts did not change over 12-months, nor did proportion of participants meeting the PA guidelines (15-21%). SB remained high throughout (11 hours/day).
Conclusion(s): The majority of CR participants are not meeting the PA guidelines during and following a 6-week CR program up to 12-months. Alternative approaches in CR should be considered to encourage participants to move more and sit less.
Implications: Immediately post event, an increased focus on decreasing SB is indicated. Over the medium to longer term CR participants should be encouraged to increase their MVPA, aiming for >10 minute bouts.
