The influence of hypoxaemia on anaerobic energy production during arm exercise (AE) has been investigated. Six men were studied during maximal AE and during 10 min of sitting submaximal AE under both normoxic (AEN) and hypoxic (AEH, respiratory hypoxia, 12% O2) conditions. Peak pulmonary oxygen uptake (VO2) during maximal AE in normoxia and hypoxia was 2.25(More)
Twenty men with a mean age of 24.9 years, who had moderate to severe asthma during childhood, underwent a follow-up examination of their physical fitness, working capacity, maximal oxygen uptake, and pulmonary function during and after physical work. Comparison was made with similar data obtained at the age of 10.9 years. The young men had a normal physical(More)
We have evaluated a mass spectrometer for use as a gas analyser in air gas mixtures. Simultaneous determinations of O2 and CO2 concentrations with both the mass spectrometer and the Haldane technique were done in ninety-nine different samples of expired air from ordinary laboratory experiments. The mean differences (+/- SD) between the two techniques for O2(More)
BACKGROUND Although several studies show that there is an increased risk of bleeding events during antidepressant treatment with selective serotonin reuptake inhibitors (SSRIs), few studies show direct effects in vitro of SSRIs on hemostasis. METHODS This study was undertaken to investigate the effects on platelet adhesion and plasma coagulation (APTT and(More)
Cardiac output ( $$\dot Q_c $$ ) was measured by a rebreathing technique, using acetylene and a mass-spectrometer for analyzing. In addition the rate of pulmonary uptake of O2 ( $$\dot VO_2 $$ ) during the rebreathing period and during a preceding steady-state period were determined. Measurements were made on 8 adult humans at rest and at different levels(More)
The anaerobic energy release during submaximal arm (AE) and leg exercise (LE) has been estimated from O2 deficit measured at the onset of exercise. Eight male subjects were studied during 8-10 min of arm or leg cycling at the same relative workload (53% of the peak exercise-induced increase in pulmonary oxygen uptake, VO2). The workloads were 78 +/- 4 W(More)
