Aerobic exercise with blood flow restriction affects mood state in a similar fashion to high intensity interval exercise.

We investigated the acute effects of aerobic exercise with blood flow restriction (BFR) on mood state in American football athletes. Twenty-two male American football athletes were randomly assigned to three experimental conditions: 1) aerobic exercise (AE: 40% VO), 2) aerobic exercise with BRF (AE + BFR: 40% VO), and 3) high-intensity interval exercise (HIIE: 80% and 40% VO during exercise and the active intervals, respectively). Mood state and total mood disturbance (TMD) were assessed before, immedia...


Blood Flow Restricted Exercise and Discomfort: A Review.

Spitz, RW, Wong, V, Bell, ZW, Viana, RB, Chatakondi, RN, Abe, T, and Loenneke, JP. Blood flow restricted exercise and discomfort: A Review. J Strength Cond Res XX(X): 000-000, 2020-Blood flow restriction exercise involves using a pneumatic cuff or elastic band to restrict arterial inflow into the muscle and block venous return out of the muscle during the exercise bout. The resultant ischemia in conjunction with low-load exercise has shown to be beneficial with increasing muscle size and strength. However, ...

Acute Muscular Responses to Practical Low-Load Blood Flow Restriction Exercise Versus Traditional Low-Load Blood Flow Restriction and High-/Low-Load Exercise.

Blood flow restriction (BFR) increases muscle size and strength when combined with low loads, but various methods are used to produce this stimulus. It is unclear how using elastic knee wraps can impact acute muscular responses compared with using nylon cuffs, where the pressure can be standardized.


Low intensity blood flow restriction exercise: Rationale for a hypoalgesia effect.

Exercise-induced hypoalgesia is characterised by a reduction in pain sensitivity following exercise. Recently, low intensity exercise performed with blood flow restriction has been shown to induce hypoalgesia. The purpose of this manuscript is to discuss the mechanisms of exercise-induced hypoalgesia and provide rationale as to why low intensity exercise performed with blood flow restriction may induce hypoalgesia. Research into exercise-induced hypoalgesia has identified several potential mechanisms, inclu...

A novel gravity-induced blood flow restriction model augments ACC phosphorylation and PGC-1α mRNA in human skeletal muscle following aerobic exercise: A randomized crossover study.

This study tested the hypothesis that a novel, gravity-induced BFR aerobic exercise (AE) model will result in greater activation of the AMPK-PGC-1α pathway compared to work rate-matched non-BFR. Thirteen healthy males (age: 22.4±3.0 yrs; V̇O2peak: 42.4±7.3 mL/kg/min) completed 2, 30-minute work rate-matched bouts of cycling performed with their legs below (CTL) and above their heart (BFR) ~2 weeks apart. Muscle biopsies were taken before, immediately, and 3 hours after exercise. Blood was drawn before a...

Vascular Function is Related to Blood Flow during High-Intensity, but Not Low-Intensity, Knee Extension Exercise.

Purpose While vascular function, assessed as the ability of the vasculature to dilate in response to a stimulus, is related to cardiovascular health, its relationship to exercise hyperemia is unclear. This study sought to determine if blood flow during submaximal and maximal exercise is related to vascular function assessed at rest. Methods Nineteen healthy adults completed multiple assessments of vascular function specific to the leg, including passive leg movement (PLM), rapid onset vasodilation (ROV), re...

The effect of blood flow restriction exercise on exercise-induced hypoalgesia and endogenous opioid and endocannabinoid mechanisms of pain modulation.

This study aimed to investigate and compare the magnitude of exercise-induced hypoalgesia (EIH) with low intensity blood flow restriction (BFR) resistance exercise (RE) at varying pressures to other intensities of resistance exercise and examine endogenous mechanisms of pain reduction.

Cerebral blood flow responses to exercise are enhanced in left ventricular assist device patients following an exercise rehabilitation program.

Cerebral blood flow during exercise is impaired in heart failure patients implanted with left ventricular assist devices (LVADs). Our aim was to determine whether a 3-month exercise training program could mitigate cerebrovascular dysfunction.

Central cardiovascular system limits to aerobic capacity.

A synthesis of data and ideas about what limits maximal aerobic capacity demonstrates the central roles of cardiac output, stroke volume and red blood cell mass in the complex physiological responses to maximal exercise. In healthy humans these factors, along with skeletal muscle blood flow, dominate systemic delivery of oxygen to the contracting muscles and set the upper limit of aerobic energy production by skeletal muscles. In elite athletes and patients with pulmonary disease the lungs can also limit ox...

Postactivation Potentiation in Blood Flow-Restricted Complex Training.

Cleary, CJ and Cook, SB. Postactivation potentiation in blood flow-restricted complex training. J Strength Cond Res XX(X): 000-000, 2020-Complex training uses a high-load (HL) resistance exercise to elicit postactivation potentiation (PAP) that is typically observed through enhanced plyometric performance. Blood flow-restricted (BFR) resistance exercise uses low loads to induce similar muscular adaptations to HL resistance exercise; however, the efficacy and feasibility of BFR complex training are unknown. ...

The Effects of Resistance Exercise With Blood Flow Restriction on Flow-Mediated Dilation and Arterial Stiffness in Elderly People With Low Gait Speed: Protocol for a Randomized Controlled Trial.

During aging, a significant loss of muscle mass, strength, and power is associated with a decline in daily functional capacities. Traditionally, resistance training is prescribed to prevent or reverse the skeletal muscle weakness, but the required training intensity may be too demanding for older people with poor physical performance. Resistance exercise with blood flow moderation (KAATSU training), originally developed in Japan, combines resistance exercise with blood flow restriction. It has been reported...

Effectiveness of Aerobic Exercise Programs for Health Promotion in Metabolic Syndrome.

Continuous and interval are the two types of aerobic exercise training commonly used for health promotion. We sought to determine which aerobic exercise training program results in larger health improvements in metabolic syndrome (MetS) individuals.

Impact of Aerobic Exercise, Sex and Metabolic Syndrome on Markers of Oxidative Stress: Results from the Study.

Oxidative stress may be involved in disease pathology and dependent on both modifiable and non-modifiable factors. This study aimed to assess exercise-induced changes in markers of oxidative stress among older, sedentary adults, and to determine the effects of metabolic syndrome (MetS) status, aerobic capacity, age, sex and weight on these biomarkers. 206 participants (mean ± SE; 66.8 ± 6.4 years, 104 women) of the study underwent a 6-month aerobic exercise intervention. At three time points, venous bloo...

The effects of exercise on vascular markers and C-reactive protein among obese children and adolescents: An evidence-based review.

Numerous studies have evaluated the effects of exercise training on obese children and adolescents. However, the impact of aerobic and/or resistance exercise alone, without any other interventions, on vascular markers and C-reactive protein (CRP) in obese children and adolescents is still not clear. We performed a literature search in Ovid Medline, PubMed, and SCOPUS databases to identify articles on the effects of exercise on vascular markers and CRP among obese children and adolescents, published between ...

Clinical safety of blood flow restricted training? A comprehensive review of altered muscle metaboreflex in cardiovascular disease during ischemic exercise.

Blood flow restriction training (BFRT) is an increasingly widespread method of exercise that involves imposed restriction of blood flow to the exercising muscle. Blood flow restriction is achieved by inflating a pneumatic pressure cuff (or a tourniquet) positioned proximal to the exercising muscle prior to, and during, the bout of exercise (i.e., ischemic exercise). Low-intensity BFRT with resistance training promotes comparable increases in muscle mass and strength observed during high-intensity exercise w...

Insights for Blood Flow Restriction and Hypoxia in Leg Versus Arm Submaximal Exercise.

To assess tissue oxygenation, along with metabolic and physiological responses during blood flow restriction (BFR, bilateral vascular occlusion) and systemic hypoxia conditions during submaximal leg- versus arm-cycling exercise.

Light Aerobic Exercise Modulates Executive Function and Cortical Excitability.

Single bouts of aerobic exercise can modulate cortical excitability and executive cognitive function, but less is known about the effect of light intensity exercise, an intensity of exercise more achievable for certain clinical populations. Fourteen healthy adults (aged 22 to 30) completed the following study procedures twice (≥7 days apart) before and after 30-minutes of either light aerobic exercise (cycling) or seated rest: neurocognitive battery (multitasking performance, inhibitory control and spatia...

The skin blood flow response to exercise in boys and men and the role of nitric oxide.

Children thermoregulate effectively during exercise despite sweating rate being consistently lower when compared with adults. The skin blood flow (SkBF) response of children to exercise is inconsistent, when compared with adults. We examined the SkBF response to exercise in children and adults, along with the potential contribution of nitric oxide to the SkBF response.

Low Dose Resistance Exercise: A Pilot Study Examining Effects on Blood Pressure and Augmentation Index Between Intensities.

The effects of resistance exercise on vascular function are unclear.

Intradermal Administration of Atrial Natriuretic Peptide Attenuates Cutaneous Vasodilation but Not Sweating in Young Men during Exercise in the Heat.

Prolonged exercise in the heat stimulates plasma release of atrial natriuretic peptide (ANP) in association with dehydration-induced reductions in blood volume. Elevated plasma ANP levels under these conditions may indirectly attenuate cutaneous blood flow and sweating responses due to the effects of this hormone on central blood volume and plasma osmolality and the resulting stimulation of nonthermal reflexes. However, it remains unclear whether cutaneous blood flow and sweating are directly modulated by A...

Effects of aerobic and inspiratory training on skeletal muscle microRNA-1 and downstream-associated pathways in patients with heart failure.

The exercise intolerance in chronic heart failure with reduced ejection fraction (HFrEF) is mostly attributed to alterations in skeletal muscle. However, the mechanisms underlying the skeletal myopathy in patients with HFrEF are not completely understood. We hypothesized that (i) aerobic exercise training (AET) and inspiratory muscle training (IMT) would change skeletal muscle microRNA-1 expression and downstream-associated pathways in patients with HFrEF and (ii) AET and IMT would increase leg blood flow (...

Aerobic exercise increases post-exercise exogenous protein oxidation in healthy young males.

The capacity to utilize ingested protein for optimal support of protein synthesis and lean body mass is described within the paradigm of anabolic competence. Protein synthesis can be stimulated by physical exercise, however, it is not known if physical exercise affects post-exercise protein oxidation. Characterization of the driving forces behind protein oxidation, such as exercise, can contribute to improved understanding of whole body protein metabolism. The purpose of this study is to determine the effec...
