The effects of practical muscle blood flow restriction training on running performance and physiology
Performing training sessions in combination with blood flow restriction (BFR) has been shown to improve muscle mass and strength development. However few studies have investigated BFR effects on aerobic performance. The purpose of this study was to determine the effect of BFR on both aerobic and …

Haemodynamic responses to heat stress and hypohydration in resting and exercising humans: Implications for the regulation of skeletal muscle blood flow
… underlying these alterations their effects on muscle blood flow are not well understood. The present thesis examined whether whole body and local heat stresses increased limb skin and muscle blood flow (Study 1) and whether hypohydration and hyperthermia compromised leg muscle, skin and …

Muscle temperature influences oxygen uptake and blood flow during single leg isokinetic exercise.
Thermal changes in muscle tissues (i.e: cooling and heating) modulate local oxygen transport from the muscle and into the cell. Whether a change in skeletal muscle oxygen transport subsequently regulate oxygen consumption (V̇ O2m) and tissue oxygenation (%TSI) during exercise is unclear. The …

Peripheral blood flow changes in response to post-exercise cold water immersion
… the magnitude of cooling in the core body, muscle and skin. Given the role of blood flow in convective heat flux, substrate delivery and metabolic waste clearance, it is important to understand the influence of different water temperatures on compartmental distribution of limb blood flow …

The role of spontaneous bursts of muscle sympathetic nerve activity in mediating peripheral vascular responses and cardiovascular hemodynamics in resting man
… is paramount for the regulation of blood flow and blood pressure. However, very little information is available to characterize the influence of spontaneously occurring sympathetic nerve activity on human blood vessels during rest. We employed spike-triggered averaging to assess the …

Effects of nitrite infusion on skeletal muscle vascular control during exercise in rats with chronic heart failure
… oxide (NO) bioavailability and impairs skeletal muscle vascular control during exercise. Reduction of nitrite (NO[subscript]2-) to NO may impact exercise-induced hyperemia particularly in muscles with pathologically-reduced O[subscript]2 delivery. We tested the hypothesis that NO[subscript]2- …

Effects of pentoxifylline on exercising skeletal muscle vascular control in rats with chronic heart failure
… in CHF rats, but the effects of PTX on skeletal muscle blood flow (BF) and vascular conductance (VC) during exercise are unknown. We tested the hypothesis that PTX would elevate skeletal muscle BF and VC at rest and during submaximal treadmill exercise in CHF rats (coronary artery ligation). CHF …

Regulation of skeletal muscle glucose uptake during contraction/ exercise by nitric oxide (NO)/ neuronal nitric oxide synthase MU (NOSμ)
During exercise/ muscle contraction, large amounts of blood glucose are taken up into skeletal muscle fibers thus removing glucose from the bloodstream. This process is regulated differently to insulin-stimulated muscle glucose uptake and is normal in humans with type 2 diabetes (T2D) and in …

The Integrative relationship between insulin and insulin-like growth factor 1 induced cardiovascular responses and sympathetic nervous responses
… to decrease cardiovascular tone and increase blood flows in skeletal muscle. Insulin has also been showed to increase sympathetic nerve activity that may play a role in the regulation of cardiovascular dynamics. This study investigated the effects of insulin and IGF-l on cardiovascular …

Assessment of Peripheral and Central Hemodynamics During Leg Exercise With "Blood Flow Restriction"
“Blood flow restriction” (“BFR”) is a type of exercise training where a pneumatic cuff is applied to the proximal portion of an exercising limb. In “BFR”, cuff inflation to 40% of an individual’s arterial occlusion pressure (AOP; cuff pressure which fully occludes limb arterial flow at rest) is …

Microvascular Function and Remodeling Due to Chronic Changes Within the Skeletal Muscle Microenvironment
The skeletal muscle microcirculation is a key regulator of local blood distribution, vascular resistance and overall blood pressure (BP). Arterioles and capillaries are two important components of the microcirculation, which can undergo remodeling such as arteriogenesis, angiogenesis, or capillary …

Skeletal Muscle Protein Metabolism and Molecular Responses to Endurance Exercise and Nutritional Interventions
It has been suggested that the gradual loss of muscle mass observed with healthy aging is the result of a resistance of aged muscle tissue to normally potent anabolic stimuli. Recent evidence indicates an age-related anabolic resistance in skeletal muscle tissue to exogenous amino acids and to a …

Vascular Effects of PHYSALIA PHYSALIS Venom

Effects of pulsed electromagnetic field therapy on symptoms associated with eccentric exercise-induced muscle damage
… consisting of eccentric contractions induces muscle damage that is characterised by muscle weakness, soreness, swelling and increased muscle stiffness. These symptoms affect daily activities and athletic performance; therefore, interventions to attenuate the symptoms and enhance recovery from …

Muscle Metaboreflex And Arterial Baroreflex: Action, Interaction And Altered Control In Heart Failure
<p>Stimulation of skeletal muscle afferents by metabolites that accumulate in the exercising muscle elicits a large pressor response, termed the muscle metaboreflex. Muscle metaboreflex activation during submaximal exercise induces large increases in arterial pressure, cardiac output, heart rate …
