PALAVRAS-CHAVES:

physical activity; blood pressure; adherence; affect.

PÁGINAS: 31
RESUMO:

Purpose: We analyzed the heart rate (HR), rating of perceived exertion (RPE) and affective response of inactive older women with hypertension during two self-selected exercise (SSE) intensity sessions. Moreover, we assessed the reproducibility of these responses. Methods: Thirteen participants (64.5 ± 4.1 years) performed two 30-minute SSE sessions outdoors. HR reserve, RPE and affective response were assessed. Paired t-test, intraclass correlation coefficient (ICC) and typical error (TE) were used for the analyzes. Results: Twelve participants (92%) exercised at moderate-vigorous intensity (≥ 40% of HR reserve) and all participants reported RPE light-moderate and positive affective response during both SSE sessions. No differences between sessions were found for HR (56.5 ± 8.0% vs. 59.1 ± 10.6% of HR reserve), RPE (11.3 ± 1.1 vs. 11.0 ± 1.5) and affective response (3.5 ± 1.1 vs. 3.4 ± 1.2) (p > 0.05). RPE presented excellent reliability (ICC = 0.82; 95% CI: 0.42 to 0.94; p < 0.01), but there was no reliability for HR (ICC = 0.40; 95% CI: -0.97 to 0.82; p = 0.43) and affective response (ICC = 0.19; 95% CI: -2.10 to 0.76; p = 0.37) between sessions. The TE between sessions for HR, RPE, and affective response were 8.1 bpm, 0.8 a.u. and 1.1 a.u., respectively. Conclusion: Inactive hypertensive older women choose a moderate-vigorous intensity when they exercise at a self-selected pace and report it as light-moderate and pleasant. These results seem to support the use of the SSE intensity as a simple approach to encourage an active lifestyle in this population.
