Twenty minutes of post-exercise hypotension are enough to predict chronic blood pressure reduction induced by resistance training in older women

Abstract

This study investigated the correlation between post-exercise hypotension (PEH) and chronic blood pressure (BP) reduction in older women after a resistance training (RT) program. Methods: Twenty-five older women (≥60 years) performed a RT program for 8 weeks, 3x/week consisting of 3 sets of 8-12 repetitions maximum in 8 exercises. Acute and chronic BP measurements were performed using automatic equipment, in which acute BP was measured before and after 10, 20, 30, 40, 50 and 60 min following the sixth exercise session, while chronic BP was measured pre and post-training. Results: Significant decrease for systolic blood pressure (SBP) was observed after the intervention period, however, the diastolic blood pressure (DBP) did not change. To acute changes in BP, SBP decreased at all times after a single RT session, while DBP increased after 40 min. The reduction for SBP after a single RT session at baseline showed positive and significant correlations with the reductions in basal SBP observed after the 8 weeks of RT, the strongest correlations were observed at 20 min. A linear relationship between the magnitude of change in chronic SBP and the 20 min for acute SBP, and 30 min for acute DBP of post-exercise was observed. Conclusion: The results suggest that acute BP lowering after RT session is a reliable predictor of chronic BP response to exercise training, and 20 min of resting, after RT training, is enough to indicate chronic response of BP as this measure was highly associated with chronic BP lowering in older women.

Cardiovascular Autonomic Responses to Aerobic, Resistance and Combined Exercises in Resistance Hypertensive Patients

“…To note, NON-RH and RH were under rigorous pharmacological therapy, which results in their well-controlled BP and may prevent PEH. In addition, the time of cardiovascular assessment seems to be crucial to identify PEH, given that some researchers [ 15 , 40 ] suggested that postexercise hypotension last for approximately 60 minutes or less, and our evaluations were performed in the first hour and 24 hours after the exercise session.…”

“…In addition, it should be stressed that the acute effects of physical exercise are associated with chronic adaptations [ 9 , 15 ]. In this sense, in an elegant study performed by Eches et al [ 15 ], the acute reduction of systolic BP after exercise may be considered a reliable predictor of the chronic adaptations to training in older women.…”

“…3,9 The antihypertensive effects of CE can occur acutely, 10,11 a phenomenon known as post-exercise hypotension (PEH), or chronically, after several sessions of physical exercise over weeks or months. 12,13 In recent years, special attention has been given to exercises that can enhance the magnitude and duration of PEH, considering that this effect would reduce cardiovascular overload in the hours after the exercise session, thus decreasing the risk of cardiovascular events. 14,15 Additionally, more recent studies have shown that individuals with greater PEH after an exercise session, tend to have a greater reduction in resting BP after weeks of training (i.e., greater chronic effect).…”
