Purpose: The primary purpose of the study was to assess if physical activity (PA) habits change between the first and final week in a phase II cardiac rehabilitation (CR) population and to determine if the PA habits differ on CR days versus non-CR days. The secondary purpose of the study was to determine if there were differences between the two PA assessment methods. Methods: There were 41 male subjects and 16 female subjects that volunteered for the study; however only 25 male subjects (age: 64.7 ± 11.4 years, BMI: 28.8 ± 4.5 kg/m2) and 11 female subjects (age: 65.2 ± 13.3 years, BMI: 31.6 ± 4.0 kg/m2) were included in the data analyses after accounting for dropouts and subject's whose data did not meet validation criteria. Subjects were required to wear both of the activity devices (pedometer and accelerometer) during both the first and final week assessments. Steps/day, activity counts/day, inactive minutes/day, light minutes/day and walking minutes/day were assessed by the Actigraph Accelerometer. Results: There was no significant difference in step counts from 5,290 ± 1,561 steps/day during the first week assessment to 5,730 ± 1,447 steps/day during the final week assessment. However, significant differences were seen between rehabilitation and nonrehabilitation days step counts/day (6,503 ± 1,663 steps/day vs. 4,517 ± 1517 steps/day, respectively). Furthermore, there was a significant increase between the first and final weeks activity counts/day (144,185 ± 56,399 counts/day vs. 165,220 ± 51,892 counts/day respectively) and a significant increase between rehabilitation and non-rehabilitation days activity counts/day (175,692 ± 58,239 counts/day vs. 133,712 ± 46,139 counts/day respectively). Conclusions: The results of the study suggest that patients are performing significantly more activity on days they attend rehabilitation versus days they do not attend rehabilitation. Furthermore, activity counts/day increased between the first and final weeks of rehabilitation and were higher on CR days vs. non-CR days, which may be due to the progressive exercise prescription associated with Phase II CR. Therefore, it was concluded that Phase II CR successfully increases the intensity of PA on CR days and between the first and final week of CR.Key Words: Cardiac Rehabilitation, Coronary Artery Disease, Pedometer, Accelerometer. / School of Physical Education, Sport, and Exercise Science
