Description
Summary:	Souza RAC, Nascimento RL, Souza JA, Almeida CMM, Silva AAS, Carvalho FO, Moraes JFVN, Moreira SR. Post-Exercise Hypotension Attenuates the Effect of Waist on Vascular Reactivity in Adults of Both Sexes. JEPonline. 2012; 15(1):87-97. Measurement of the waist circumference has been highlighted as a major factor in increased risk of vascular reactivity and therefore the occurrence of hypertension throughout time. On the other hand, studies investigating the acute effects of exercise on blood pressure have shown the phenomenon of post-exercise hypotension (PEH). The purpose of this study was to analyze the relationship between the waist circumference and vascular reactivity, and to verify if PEH (after a combined exercise session) attenuates this relationship. Fifty adults of both sexes (28.8 ± 7.1 yr; 73.3 ± 13.3 kg; 172.9 ± 8.8 cm) volunteered to perform measurements of waist circumference and vascular reactivity of blood pressure. In addition, 20 individuals (10 males and 10 females; 33.4 ± 6.9 yr, 70.2 ± 15.8 kg, 170.4 ± 11.5 cm) performed a combined session of resistance and aerobic exercise with duration of 36 min and a control session without exercise on the same period of different days and in randomized order. The vascular reactivity was analyzed by the Cold Pressor Test, which was applied at rest to all the subjects (n = 50) and 1 hr after the experimental sessions (n = 20). The findings indicate that there is a relationship between waist circumference and vascular reactivity during (r = .49/.53; P<0.01) and after (r = .52/.55; P<0.01) the Cold Pressor Test. Also, a single combined exercise session at moderate intensity enabled PEH and attenuated the influence of waist circumference in increasing vascular reactivity in adults of both sexes.
