Low blood pressure is sustained during subsequent activities of daily living performed after power training in older women

Abstract

The present study aimed to examine the effects of a prior session of power training on blood pressure values during tasks that mimic the activities of daily living in hypertensive and normotensive older women. A randomized crossover experimental design was used for this study. Eleven older women (age, 66.1±1.2 years; body mass index, 26.7±4.8 kg/m2; systolic blood pressure, 133.9±23.4 mmHg) were recruited to participate. Volunteers were randomly underwent to a single session of physical exercise equalized by training volume, characterized by 3 sets of 8–10 repetitions in 8 different exercises. However, Power training session was performed at a higher intensity (moderate) than Sham session (rest/very, very easy ). Immediately after the end of the exercise session, subjects were assigned to perform five tasks that mimic the activities of daily living. Hemodynamic parameters were recorded before and immediately after the session of physical exercise, as well as in the end of each of the tasks. Results demonstrated significant elevations in systolic blood pressure and pulse pressure values during the performance of the tasks after the Sham session. However, values were not altered in the power training session. Data of the present study indicate that an acute session of power training can maintain blood pressure values lower during the subsequent performance of tasks that mimic activities of daily living in older women.

Non-periodized and Daily Undulating Periodized Resistance Training on Blood Pressure of Older Women

“…It is well-accepted, that the chronic adaptations presented by the cardiovascular system in response to physical exercise may be due to the sum of the acute effects (Terra et al, 2008 ; Moreira et al, 2016 ). In this sense, an increasing number of studies have shown that a session of low-to-moderate load power exercise may cause post-exercise hypotension (PEH) in hypertensive older women (Coelho-Júnior et al, 2017a ; Coelho Junior et al, 2017b ). In addition, Arazi et al ( 2013 ) and Ramírez-Campillo et al ( 2016 ) demonstrated that PEH occurred independently of power exercise intensity (Arazi et al, 2013 ; Ramírez-Campillo et al, 2016 ), which is an important practical aspect for the prescription of exercise in hypertensive subjects.…”

“…All these features make power resistance exercise a secure and effective option to DUP programs. In fact, as the cardiovascular responses to power resistance exercise seem to be dependent on the velocity of concentric muscle contraction, regardless exercise intensity (Coelho-Júnior et al, 2017a ; Coelho Junior et al, 2017b ), it can be an excellent alternative to the lower exercise session of DUP. In addition, a lower cardiovascular stress may be expected during power resistance exercise performance, since it does not include high training loads, fatiguing exercises, and Valsalva maneuver, all variables associated with desirable increases on blood pressure during exercise (MacDougall et al, 1985 b).…”

Combined Aerobic and Resistance Exercises Evokes Longer Reductions on Ambulatory Blood Pressure in Resistant Hypertension: A Randomized Crossover Trial

“…Our findings have practical applications, given that low BP levels after acute exercise may contribute to low cardiovascular risk during the performance of ADL [23,24]. Hence, health professionals responsible for exercise prescription in patients with RH should preferably prescribe COM exercise, instead of either AER or RES alone.…”

“…PEH is found after aerobic (AER) and resistance (RES) exercises in NON-RH and normotensive people [19][20][21][22]. Furthermore, PEH may predict the success of exercise protocols [21,22] and likely contribute to low cardiovascular risk during the performance of activities of daily living [23,24].…”

Effects of Combined Resistance and Power Training on Cognitive Function in Older Women: A Randomized Controlled Trial

“…According to Cherup et al [35], increased aerobic capacity with PT may modify neural structures and stimulate vascular branching, contributing to improvements in neuronal function. This data suggest that the combination of these types of exercise training may elicit similar or greater changes in cognition than TRT alone, while older individuals are submitted to low cardiovascular and osteoarticular stresses [52][53][54]. However, no prior evidence investigated the effects of combined PT and TRT (PTRT) on cognitive function of older adults.…”
