Resposta hipotensora de idosas hipertensas é influenciada pelo grupamento muscular envolvido no exercício resistido/Hypotensive responses of elderly woman hypertension are influenced by muscle mass group in resistance exercise

The aim of present study was to investigate the influence of two different types of resisted exercise (RE) on hypotensive responses in elderly women with arterial hypertension. The sample was composed by 24 elderly women, physically activity classified as arterial hypertension I. The volunteers were familiarized with exercise execution and determined one repetition maximal load (1RML) to verify the voluntary maximal load (VML). After 48 hours of one repetition maximal load, was performed in two different moments separated by 48 hours: a) arm curl exercise session; b) Leg press 45° exercise session. SBP and DBP were monitored before exercise, during exercise and 10 minutes after exercise. The results demonstrated increases in SBP during exercise being higher in Leg press 45° (p = .006). However, after exercise was verified hypotensive effect in SBP (p = .027) and DBP (p = .015) only in leg press 45°. In conclusion, large muscle group promotes higher hypotensive effect in elderly with hypertension as compared to small muscle group. [PUBLICATION ABSTRACT]
