RESUMO
As part of a home-based rehabilitation program, 24 older adult patients (71 ± 3 years) with abdominal aortic aneurysm (AAA) disease underwent 3 days (12 awake hr/day) of activity monitoring using an accelerometer (ACC), a pedometer, and a heart rate (HR) monitor, and recorded hourly activity logs. Subjects then underwent an interview to complete a 3-day activity recall questionnaire (3-DR). Mean energy expenditure (EE) in kcals/ day for HR, ACC, and 3-DR were 1,687 ± 458, 2,068 ± 529, and 1,974 ± 491, respectively. Differences in EE were not significant between 3-DR and ACC, but HR differed from both ACC (p < .001) and 3-DR (p < .01). ACC and 3-DR had the highest agreement, with a coefficient of variation of 7.9% and r = .86. Thus, ACC provided a reasonably accurate reflection of EE based the criterion measure, an activity recall questionnaire. ACC can be effectively used to monitor EE to achieve an appropriate training stimulus during home-based cardiac rehabilitation.

PURPOSE: Concurrent and construct validity of the OMNI-Cycle Scale of Perceived Exertion were examined using young adult women and men (18-32 yr). METHODS: Concurrent validity was established by correlating OMNI-Cycle Scale ratings of perceived exertion (RPE) with oxygen consumption (.VO2) and heart rate (HR) responses to a load-incremented cycle ergometer protocol. Construct validity was established by correlating RPE derived from the OMNI-Cycle Scale with RPE from the Borg (6-20) Scale. RPE, .VO2, and HR were measured during each exercise stage. RESULTS: The range of exercise responses across the incremental test for the female and male groups was .VO2 = 0.92-2.74 L.min-1, HR = 107.2-167.2 beats.min-1, and OMNI Scale RPE-Overall, RPE-Legs, and RPE-Chest 1.0-9.1. Correlation/regression analyses indicated that RPE-Overall, RPE-Legs, and RPE-Chest distributed as a positive linear function of both .VO2 and HR (r = 0.81 to 0.95; P < 0.01). Undifferentiated and differentiated RPE-OMNI Scale distributed as a positive linear function of RPE-Borg Scale (r = 0.92 to 0.97; P < 0.01). ANOVA indicated that OMNI-Cycle RPE-Legs was higher (P < 0.01) than RPE-Chest at each exercise stage for both genders. CONCLUSION: Concurrent and construct evidence supports use of the OMNI Scale by adult women and men to estimate RPE during cycle exercise.
