OBJECTIVE: To assess the efficacy of a strategy, based on telephone support
oriented by accelerometer measurements, on the adherence to physical activity
(PA) recommendations in cardiac patients not achieving PA recommendations.
DESIGN: Prospective and randomized study. SETTING: A cardiac rehabilitation
program (CRP) at a clinic. PARTICIPANTS: Stable, noncompliant cardiac (coronary
artery disease, heart failure, post-cardiovascular surgery) patients (weekly
moderate-intensity PA <150 min) were randomly assigned to an intervention group
(n=19) or a control group (n=10). INTERVENTIONS: The intervention group wore an
accelerometer for 8 weeks. Every 15 days, feedback and support were provided by
telephone. The control group wore the accelerometer during the 8th week of the
intervention only. MAIN OUTCOME MEASURES: Active energy expenditure (EE) (in
kilocalories) and the time spent doing light, moderate, or intense PA (minutes
per week). RESULTS: In the intervention group, the time spent at
moderate-intensity PA increased from 95.6+/-80.7 to 137.2+/-87.5 min/wk between
the 1st and 8th week (P=.002), with 36.8% of the sample achieving the target
amount of moderate-intensity PA. During the 8th week, the EE averaged
543.7+/-144.1 kcal and 266.7+/-107.4 kcal in the intervention group and control
group, respectively (P=.004). CONCLUSIONS: Telephone support based on
accelerometer recordings appeared to be an effective strategy to improve
adherence to PA in noncompliant patients. This intervention could be implemented
after a CRP as an inexpensive, modern, and easy-to-use strategy.
