Affective responses to different prescriptions of high-intensity interval exercise in hypertensive patients.

BACKGROUND: Studies have indicated that high-intensity interval training (HIIT) promotes similar acute reductions on blood pressure (BP) when compared to continuous moderate aerobic exercise. However, it has been associated with lower affective responses to exercise. Therefore, strategies to improve affective responses to exercise are needed. The purpose of this study was to verify the effect of different prescriptions of HIIT on the affective responses of hypertensive elderly women. METHODS: This is a cross-sectional study. Twenty hypertensive women (65.3±4.2 years) performed four HIIT sessions: 10×1:1 at ±20% of self-selected intensity [SSI] Self20), 10×1:1 at ±30% of SSI (Self30), 10×1:1 at ±40% of SSI (Self40) and an imposed intensity session 5×2-min intervals at 80-85% interspersed with 2-min intervals at 40-50% VO2peak (ImpVO2) and one control session with participants remaining in the sitting position for 28 minutes. Affect response, rating of perceived exertion (RPE) and heart rate (HR) were recorded every five minutes during exercise, and systolic blood pressure (SBP), diastolic blood pressure (DBP) and HR were assessed before and after sessions. The effect of session and moment on the psychophysiological variables was examined by analysis of variance. RESULTS: Affect was lower in the ImpVO2 when compared to SSI sessions. There was no difference in RPE between sessions. The percentage of HRpeak was higher in ImpVO2 compared to SSI sessions. There were no differences in SBP and DBP responses between the sessions. CONCLUSIONS: HIIT prescribed based on SSI promoted higher affective responses than HIIT prescribed from 80-85%/40-50% VO2peak with similar BP responses.

Quality of life in chronic venous disease women / Qualidade de vida em mulheres com doença venosa crônica

The aim of the study was to verify the relationship between physical function and quality of life in women with chronic venous disease. Physical function was evaluated by the tests: chair stand test (lower limbs strength), arm curl (upper limbs strength), 6-minute walk (aerobic fitness), back scratch (upper limbs flexibility), sit and reach (lower limbs flexibility), and time up-and-go (agility). Quality of life was assessed by The World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire, which is composed by physical, psychologic, social, environmental, and global do-mains. For statistical analysis, the Pearson correlation coefficient was used with an alpha of 5%. Patients evaluated were 32 (61.27 ± 7.78 years). A significant correlation was observed between the physical domain of quality of life with the chair stand test (r = 0.46; p = 0.001), arm curl (r = 0.39, p = 0.002), and 6-minute walk test (r = 0.45; p = 0.001). Also, chair stand test presented low correlation with global quality of life (r = 0.36, p = 0.004). The physical domain of quality of life measured by the WHOQOL-BREF questionnaire is related to lower and upper limbs strength and physical fitness in women with chronic venous disease but presented weak correlation with the global domain of quality of life. Thus, in women with CVD, the muscular strength of lower and upper limbs, and physical fitness is correlated with the physical domain of quality of life

O objetivo do estudo foi verificar a relação entre capacidade física e qualidade de vida em mulheres com doença venosa crônica. A capacidade física foi avaliada pelos testes: sentar e levantar (força de membros inferiores), flexão de braço (força de membros superiores), teste de caminhada de seis minutos (resistência ae-róbia), alcançar as costas (flexibilidade de membros superiores), sentar e alcançar (flexibilidade de membros inferiores) e levantar ir-e-vir (agilidade). Qualidade de vida foi avaliada pelo questionário da Organi-zação Mundial de Saúde WHOQOL-BREF composto pelos domínios físico, psicológico, social, ambiental e global. Correlação de Pearson foi usada para verificar a relação entre as variáveis. O valor de alpha foi estabelecido em 5%. Foram avaliados 32 pacientes (61.27 ± 7.78 anos). Correlações significativas foram ob-servadas entre os domínios físico de qualidade de vida com o teste de sentar e levantar (r = 0.46; p = 0.001), flexão de braço (r = 0.39; p = 0.002), e teste de seis minutos de caminhada (r = 0.45; p = 0.01). Além disso, o teste de sentar e levantar apresentou fraca correlação com o domínio qualidade de vida global (r = 0.36; p = 0.004). Conclui-se que a resistência aeróbia e força muscular de membros superiores e inferiores tem relação com o domínio físico de qualidade de vida em mulheres com doença venosa crônica
