“…For example, Polito et al (2007) demonstrated similar blood pressure responses between heavy weights training with few repetitions compared with lighter weights training for more repetitions. Importantly, LL BFR resulted in elevated blood pressures when compared with LL and HL, findings similar to those previously reported for older hypertensive ( Pinto and Polito, 2016 ) and normotensive ( Vieira et al, 2013 ; Sardeli et al, 2017 ) individuals, as well as for healthy young men ( May et al, 2017 ). These findings have practical relevance for practitioners, especially if they are considering the implementation of BFR training in hypertensive patients.…”

Hemodynamic Responses to Low-Load Blood Flow Restriction and Unrestricted High-Load Resistance Exercise in Older Women

et al. 2018

Introduction: Blood flow restriction (BFR) during low-load resistance exercise increases muscle size similarly to high-load training, and may be an alternative to lifting heavy weights for older people at risk of sarcopenia. However, few studies have addressed the safety of such exercise in older people, or whether this is impacted by the actual exercises performed during training. This study aimed to compare the acute hemodynamic and perceptual responses during low-load BFR exercise to unrestricted low-load and high-load exercise in older women, and to determine whether these responses depend on the type of exercise performed.Methods: Fifteen older women (63–75 year) were assessed for maximal strength (1RM) in the leg press and leg extension. Participants then completed three protocols using these exercises in a randomized order: (1) low-load exercise (LL); (2) low-load exercise with BFR (LLBFR), and; (3) high-load exercise (HL). Blood pressure was assessed at baseline and after each set, and impedance cardiography measured cardiovascular function during trials. Rating of perceived exertion (RPE) and muscle soreness scores were obtained throughout trials.Results: Baseline hemodynamic values were consistent between trials. Systolic, diastolic, and mean arterial pressures were higher in LLBFR compared with HL and LL (p ≤ 0.021). The LL condition resulted in lower heart rate (p ≤ 0.002) and rate-pressure product (p ≤ 0.011) responses compared with LLBFR and HL. The leg press generally conferred greater hemodynamic and perceptual demands than the leg extension for all conditions (p ≤ 0.002). RPE was lower during LL compared with LLBFR and HL (p ≤ 0.008), and there were no between-condition differences in perceived muscle soreness.Conclusion: The blood pressure data indicate that LLBFR causes greater stress on the vasculature than LL and HL exercise, and that the leg press was generally more demanding than the leg extension. While additional cardiovascular measures were similar between LLBFR and HL conditions, caution should be advised when prescribing BFR exercise for individuals with compromised cardiac or vascular function. Nevertheless, LLBFR and HL exercise were perceived similarly, indicating that BFR training may be viable for healthy older people.

“…There is evidence that a RT-BFR exercise session induces higher systolic and diastolic blood pressure increments and slower parasympathetic recovery compared with high intensity RT in elderly. 57 Nonetheless, a recent meta-analysis 58 showed that blood pressure responses to RT-BFR are similar to those observed during high intensity RT, regardless of the ageing group. Taken together, there is evidence suggesting that changes in blood pressure during RT-BFR are similar to traditional high intensity RT in different populations.…”

Significant muscle wasting is generally experienced by ill and bed rest patients and older people. Muscle wasting leads to significant decrements in muscle strength, cardiorespiratory, and functional capacity, which increase mortality rates. As a consequence, different interventions have been tested to minimize muscle wasting. In this regard, blood flow restriction (BFR) has been used as a novel therapeutic approach to mitigate the burden associated with muscle waste conditions. Evidence has shown that BFR per se can counteract muscle wasting during immobilization or bed rest. Moreover, BFR has also been applied while performing low intensity resistance and endurance exercises and produced increases in muscle strength and mass. Endurance training with BFR has also been proved to increase cardiorespiratory fitness. Thus, frail patients can benefit from exercising with BFR due to the lower cardiovascular and join stress compared with traditional high intensity exercises. Therefore, low intensity resistance and endurance training combined with BFR may be considered as a novel and attractive intervention to counteract muscle wasting and to decrease the burden associated with this condition.

This article is a methodological description of a randomized clinical trial (ClinicalTrials.gov U1111-1181-4455) aiming to evaluate the time-course (monthly) and associations between blood pressure changes and other health-related adaptations in response to exercise training in hypertensive elderly. Methods: The patients will be randomized to a control or combined training group interventions (aerobic and resistance exercise), with monthly assessments in four months. Although, the changes in baseline blood pressure is the primary clinical outcome, the secondary outcomes include: body composition, cardiorespiratory fitness, muscle strength, arterial stiffness, baroreceptor sensitivity, cardiovascular autonomic modulation, inflammatory markers, oxidative stress, growth factors, tissue remodeling markers, metabolic profile, renal function, cognitive function and quality of life. Results: To support the understanding of the blood pressure changes in hypertensive elderly, a time-course of exercise-induced adaptations including cardiovascular and immunological adaptations are fundamental for research in this field. Conclusion: To investigate the time-course of combined training-induced adaptations including all the diverse aspects of health in hypertensive elderly a well-controlled protocol design is necessary, mainly to clarify the relationship between cardiovascular and immunological exercise-induced adaptations.
