Effect of High-Intensity Interval Exercise versus Continuous Low-Intensity Aerobic Exercise with Blood Flow Restriction on Psychophysiological Responses: A Randomized Crossover Study.

This study compared the effect of continuous low-intensity aerobic exercise with blood flow restriction (LI-AE-BFR) versus high-intensity interval exercise (HIIE), matching total external mechanical work between conditions, on perceptual (exertion, pain, affective and pleasure) and physiological responses (heart rate [HR], blood lactate [BL] and muscle fatigue). Ten healthy untrained men (25.6 ± 3.

Acute Effect of Resistance Training With Blood Flow Restriction on Perceptual Responses: A Systematic Review and Meta-Analysis.

Context: Several studies have compared perceptual responses between resistance exercise with blood flow restriction and traditional resistance exercise (non-BFR). However, the results were contradictory.

Objectives: To analyze the effect of RE+BFR versus non-BFR resistance exercise [low-load resistance exercise (LL-RE) or high-load resistance exercise (HL-RE)] on perceptual responses.

Practical Blood Flow Restriction Training: New Methodological Directions for Practice and Research.

Most studies with blood flow restriction (BFR) training have been conducted using devices capable of regulating the restriction pressure, such as pneumatic cuffs. However, this may not be a viable option for the general population who exercise in gyms, squares and sports centers. Thinking about this logic, practical blood flow restriction (pBFR) training was created in 2009, suggesting the use of elastic knee wraps as an alternative to the traditional BFR, as it is low cost, affordable and practical.

Aerobic exercise with blood flow restriction: Energy expenditure, excess postexercise oxygen consumption, and respiratory exchange ratio.

We compared the effects of aerobic exercise with and without blood flow restriction (BFR) to high-intensity aerobic exercise on energy expenditure (EE), excess Postexercise oxygen consumption (EPOC), and respiratory exchange ratio (RER) during and after exercise. Twenty-two recreationally active males randomly completed the following experimental conditions: AE-aerobic exercise without BFR, AE + BFR-aerobic exercise with BFR, HIAE-high-intensity aerobic exercise, CON-non-exercise control condition. EE was significantly (p < 0.

The perceptual responses of individuals with multiple sclerosis to blood flow restriction versus traditional resistance exercise.

Background: Low-load resistance exercise with blood flow restriction (BFR-RE) has been shown capable of improving neuromuscular parameters in several clinical populations, however, its tolerability and effects on individuals with multiple sclerosis (MS) remains unknown.

Objective: To investigate the perceptual responses of individuals with MS to BFR-RE versus traditional high-load resistance exercise (HL-RE).

Methods: Four men and eleven women diagnosed with relapsing-remitting MS randomly completed the following experimental trials: 1) BFR-RE four sets of 30-15-15-15 repetitions, at 20% of one-repetition maximum (1-RM) of leg-press (LP) and knee-extension (KE), with 50% of BFR, and a 1-min rest interval between sets; 2) HL-RE- four sets of 8-10 repetitions, at 70% 1-RM of LP and KE, with the same rest intervals.

Health-related physical fitness of military police officers in Paraiba, Brazil.

Background: An adequate relationship among health-related physical fitness (HRPF) components improve the professional performance of military police officers (MOPs).

Objective: To investigate the correlation among HRPF components for Special Police Operations (BOPE) and Traffic Police (BPTRAN) Battalion MOPs.

Method: The sample comprised 47 male MOPs aged 26 to 49 years old divided in two groups BOPE (N=25) and BPTRAN (n=22).

Perceptual responses to continuous versus intermittent blood flow restriction exercise: A randomized controlled trial.

We investigated the perceptual responses to resistance exercise (RE) with continuous and intermittent blood flow restriction (BFR). Fourteen males randomly completed the following exercise conditions: low-load RE with continuous BFR (cBFR), low-load RE with intermittent BFR (iBFR), low-load RE without BFR (LI), and traditional high-load RE (HI). Participants completed 4 sets of 30-15-15-15 repetitions of bilateral leg press and knee extension exercises during the low-load conditions, at 20% of one-repetition maximum (1-RM), a 1.

Physiological and perceptual responses to aerobic exercise with and without blood flow restriction. J Strength Cond Res 35(9): 2479-2485, 2021-Although previous studies have demonstrated the potential benefits of aerobic exercise (AE) with blood flow restriction (BFR), these findings have been limited by the approaches used to determine the occlusive pressure.

Mood Effects of Blood Flow Restriction Resistance Exercise Among Basketball Players.

This study compared the acute effects of resistance exercise with and without blood flow restriction (BFR) on basketball players' mood states. A total of 11 male basketball players (M age = 19.9, SD = 2.

Rating of Perceived Exertion During Circuit Weight Training: A Concurrent Validation Study.

The aim of this study was to determine whether rating of perceived exertion (RPE) is a valid method to control the effort during the circuit weight training (CWT) in trained men. Ten men (21.3 ± 3.

Evaluating the Cassandra NoSQL Database Approach for Genomic Data Persistency.

Rapid advances in high-throughput sequencing techniques have created interesting computational challenges in bioinformatics. One of them refers to management of massive amounts of data generated by automatic sequencers. We need to deal with the persistency of genomic data, particularly storing and analyzing these large-scale processed data.

Development and validation of an automated step ergometer.

Laboratory ergometers have high costs, becoming inaccessible for most of the population, hence, it is imperative to develop affordable devices making evaluations like cardiorespiratory fitness feasible and easier. The objective of this study was to develop and validate an Automated Step Ergometer (ASE), adjusted according to the height of the subject, for predicting VO2max through a progressive test. The development process was comprised by three steps, the theoretical part, the prototype assembly and further validation.
