Five subjects exercised with the knee extensor of one limb at work loads ranging from 10 to 60 W. Measurements of pulmonary oxygen uptake, heart rate, leg blood flow, blood pressure and femoral arterial‐venous differences for oxygen and lactate were made between 5 and 10 min of the exercise. Flow in the femoral vein was measured using constant infusion of saline near 0 degrees C. Since a cuff was inflated just below the knee during the measurements and because the hamstrings were inactive, the… Expand
Skeletal muscle perfusion in electrically induced dynamic exercise in humans.
Leg blood flow, blood pressure and metabolic responses were evaluated in six men during incremental one-legged dynamic knee extension exercise tests (no load exercise-40 W); one performed withExpand
Skeletal muscle blood flow in humans and its regulation during exercise.
TLDR
Adenosine is a primary candidate as it can be demonstrated to cause a change in limb blood flow when infused i.a., that is similar in time and magnitude as observed in exercise, and become elevated in the interstitial space (microdialysis technique) during exercise to levels inducing vasodilation.

TLDR
In conclusion, common and profunda femoral artery diameters are sufficient to ensure delivery to the quadriceps muscle, however, the common branch may impose a limitation during ergometer cycle exercise. Expand
Effect of contraction frequency on leg blood flow during knee extension exercise in humans.
TLDR
In humans performing knee extension exercise in the supine position, muscle contraction frequency and/or muscle tension development may appreciably affect both the MBF and the amplitude of the contraction-to-contraction oscillations in muscle blood flow. Expand
Muscle contraction-blood flow interactions during upright knee extension exercise in humans.
TLDR
It is concluded that at the lightest work rate, the muscle pump had a net positive effect on MBFM, and at the three higher work rates tested, any enhancement to flow during relaxation was insufficient to fully compensate for the contraction-induced impedance to muscle perfusion. Expand
Muscle metabolism during graded quadriceps exercise in man
TLDR
Total fat oxidation in muscle increases from rest to light exercise, but then remains constant with exercise intensity up to heavy exercise, however, with increasing exercise intensity, oxidation of plasma free fatty acids increases and accordingly oxidation of other fat sources decreases. Expand
Cardiac output and leg and arm blood flow during incremental exercise to exhaustion on the cycle ergometer.
TLDR
Vasoconstrictor signals efficiently oppose the vasodilatory metabolites in the arms, suggesting that during whole body exercise in the upright position blood flow is differentially regulated in the upper and lower extremities. Expand
Reduced leg blood flow during dynamic exercise in older endurance-trained men.
TLDR
It is indicated that leg blood flow and vascular conductance during cycle ergometer exercise are significantly lower in older endurance-trained men in comparison to their younger counterparts. Expand
Effect of temperature on skeletal muscle energy turnover during dynamic knee-extensor exercise in humans.
TLDR
Within the range of temperatures studied, passively increasing muscle temperature before exercise has no effect on muscle energy turnover during dynamic exercise. Expand
Blood flow and muscle oxygenation during low, moderate, and maximal sustained isometric contractions.
TLDR
Unlike dynamic or intermittent isometric exercise, the results indicate blood flow is not linearly graded with intensity or directly coupled with oxygenation during sustained isometric contractions. Expand

Influence of age on the local circulatory adaptation to leg exercise.
TLDR
It is concluded that blood flow to the leg in middle-aged men rises in a curvilinear manner in response to exercises at work loads increased in steps to near maximal levels of work intensity. Expand
Central and regional circulatory effects of adding arm exercise to leg exercise.
TLDR
The findings indicate that the oxygen supply to one large group of exercising muscles may be limited by vasoconstriction or by a fall in arterial pressure, when anotherlarge group of muscles is exercising simultaneously. Expand
Central and regional circulatory adaptations to one-leg training.
TLDR
The findings indicate that one- leg exercise, compared with two-leg exercise, involves circulatory adaptations that respond differently to one-leg training and implies that oxygen supply to one large muscle group of exercising muscles may be limited by vasoconstriction when another large group of muscles is exercising simultaneously.

Tests for accuracy in vitro and in dog experiments and in relation to the anatomical and functional conditions in the popliteal/distal femoral vein of man and patients suffering from ischaemic lower limb disease are presented. Expand

Measurements included muscle glycogen and lactate concentrations of the two legs as well as the blood flow and the a-v difference for O2, glucose and lactates. Expand
Cardiovascular responses to exercise as functions of absolute and relative work load.
TLDR
The cardiovascular responses to exercise are determined to a large extent by the active muscle mass and the absolute oxygen uptake, with the principal feature appearing to be the tight linkage between systemic oxygen transport and utilization. Expand

TLDR
Results show that the 133Xe clearance method considerably underestimates blood flow in dog muscles. Expand

TLDR
It seems likely that these factors, acting directly or indirectly, are the principal chemicals responsible for the maintenance of the vasodilation seen in canine skeletal muscle during heavy exercise. Expand
