...Glenn A. BARKER; Simon GREEN; Anita A. GREEN; Philip J. WALKER In the present study, we tested the hypothesis that walking intolerance in intermittent claudication (IC) is related to both slowed whole body oxygen uptake ( V O 2 ) kinetics and altered activity of the active fraction of the pyruvate...

... was obtained from at least one parent. Infants were studied in the supine or lateral posture, wrapped in their usual clothing, at the ambient temperature of the nursery (2426°C). In each infant, measurements of breathing pattern, Key words: neonatal reslliration, oxygen uptake, pulmonary reflexes, regulation...

... of oxygen, carbon dioxide, glucose and lactate were taken from an artery, a hepatic vein and a femoral vein. Blood flow in the splanchnic region was measured by constant infusion of Indocyanine Green. Leg blood flow was measured by venous occlusion strain-gauge plethysmography. Oxygen uptake and carbon...

...H. Nordgren; U. Freyschuss; B. Persson 1. Reference values for systolic blood pressure during exercise are provided for 88 healthy adolescents (12–22 years of age) of both sexes. Data were related to oxygen uptake, heart rate, blood lactate concentration, rate of perceived exertion, age, sex, body...

...C. H. Kong; F. D. Thompson; F. J. Imms 1. Cardiac index, oxygen uptake and haemoglobin concentration have been measured in eight patients with end-stage renal failure, and the values compared with those in eight healthy control subjects. Assuming the arterial blood to be 97% saturated, the oxygen...

...Lydia Makrides; George J. F. Heigenhauser; Neil Mccartney; Norman L. Jones 1. Fifty males and 50 females, 15-71 years of age, exercised maximally for 30 s on an isokinetic ergometer at a pedalling frequency of 60 rev./min. Results were compared with maximal oxygen uptake (VO 2 max.) obtained...

... and carbon dioxide, oxygen uptake and carbon dioxide output were measured continuously during each test. 2. Anaerobic threshold (AT) was determined non-invasively as the onset of sustained increases in each of the ventilatory equivalent for oxygen, expired and end-tidal concentrations of oxygen followed...

The infusion of indomethacin was followed by a decreased cardiac output (from 7·3 ± 0·3 to 6·3 ± 0·3 litres/min) and an increased mean systemic blood...

... with the uninjured (6·43 ± 0·87 litres). Associated with this loss was a similar reduction in the net maximum oxygen uptake achieved in one-leg cycling, from 1·89 ± 0·21 l/min in the uninjured leg to 1·57±0·18 l/min in the injured. 3. Measured by a percutaneous needle biopsy technique, a reduction of 42% was found...

...Patricia G. B. Baker; R. F. Mottram 1. Methods are described for study of metabolism of human skeletal muscle in situ , at rest and during mild sustained contraction in the fed and fasted states. 2. At rest the average oxygen uptake was 0.29 ml min −1 100 ml of muscle −1 and the carbon dioxide...

... at rest, during the walk and for 15 min post-exercise. The mean values for four age groups of twenty subjects each were analysed statistically. 3. A near rectilinear decrease in walk-time and maximum oxygen uptake (V̇o 2max .) (ml min −1 kg −1 ) with advancing age was observed. A difference in V̇o 2max...
