Resumo
INTRODUCTION: Hypertension could impaire the quality of life (QOL) and healthrelated
quality of life (HRQOL). Aerobic and resistance training improve cardiovascular
performance, but there is little evidence regarding the effects related to QOL, HRQOL
and functional capacity in hypertensive women. OBJECTIVES: To assess the effects of
aerobic and resistance training on QOL and functional capacity in hypertensive women.
METHODS: Randomized clinical trial conducted at Hypertension League Federal
University of Goias - Brazil. Sample: hypertensive women, 50 years, non-participants
in exercise programs, satisfactory treadmill test (Bruce protocol) and with a minimum 6-
month treatment at service. Subdivided: aerobic group (GA) (n=21) and resistance
group (GR) (n=20). Interventions: 2 months (2x/week) of aerobic exercise and
resistance training. Intensity of aerobic group: light to moderate (4 to 7 of adjusted Borg
Scale). Resistance: up to 60% of 1 RM Test. Two series of 12 to 15 repetitions. Before
and after the intervention was applied WHOQOL-bref to evaluate QOL, the SF-36 for
HRQOL and 6-minute walk test (6`WT) to measure the functional capacity. Statistical:
student`s-t, Fisher, Mann-Whitney U, Chi-square and Wilcoxon tests. Level of
significance: p <0.05. RESULTS: Initially the groups were homogeneous regarding
clinical, anthropometric, sociodemographic and WT6’ (p 0.05). The groups were also
homogeneous in WHOQOL-bref scores except on the psychological and social
relationships domains, and the GR had higher scores on these. On SF-36, the groups
were different at the beginning only at physical function domain, and the GA presented
higher score in this domain. After intervention, there was a significant improvement in all
WHOQOL-bref domains in GA and at GR the improvement ocurred only in physical
health domain. Regarding SF-36 there was a significant improvement in 7 of 8 domains
at GA (exception for mental health). At GR, were observed similar results. There were
no changes in weight, body mass index, waist circunference, blood pressure and heart
rate after the intervention. (p 0.05). There was an increase at functional capacity
(longer distance on 6`WT - p 0.001) in both groups. CONCLUSION: The two types of
physical exercise, promoted beneficial effects in different magnitudes in QOL, similar in
HRQOL and functional capacity. These results suggest that, according the focus and
objectives established, both exercises can be effective as a treatment strategy in search
of better QOL in hypertensive woman.
