摘要：Barreto CB, Aguiar SS, Palmeira R, Coelho Junior HJ, Gargaglione EML, Oliveira JF, Pires FO, Asano RY. What is the Minimum Volume of Aerobic Physical Exercise Necessary to Elicit Postexercise Hypotension? JEPonline 2015;18(6):1-12. Benefits from physical exercise are not restricted to a chronic stimulus. They can also be observed after a single session of exercise (such as the phenomenon called postexercise hypotension, PEH). While moderate aerobic exercise is known to cause PEH, the minimum exercise volume to elicit this phenomenon is not well elucidated. Twenty-two normotensive sedentary healthy adults were allocated to two groups: the Control Group (CG, n = 9) and the Exercise Group (EG, n = 13). The EG was randomly assigned to three aerobic exercise protocols with different volumes (10 min [S10], 20 min [S20], and 30 min [S30]) at 60% of heart rate reserve. Before and during the 30 min after the exercise bout, blood pressure was recorded. Results showed that moderate aerobic exercise sessions lasting 20 and 30 min significantly decreased the systolic blood pressure throughout the period after the exercise bout (S20: P<0.0001, ES15’ = 1.3, ES30’ = 1.6; S30: P<0.0001, ES15’ = 1.1, ES30’ = 1.4), Hence, the minimum exercise time to observe PEH after engaging in moderate aerobic exercise is 20 min.
