Many investigations have shown that the coincidence between the ventilatory thresholds and those thresholds using the lactate response does not happen all of the time, suggesting that there is no relationship between the cause-effect between these phenomena. Thus, the present study had as main purpose to compare and correlate the Oxygen consumption (VO2), the power (W), and the heart rate (HR) ...

BACKGROUND Cardiac output is effectively redistributed to working muscle by regional changes in vascular resistance. However, there has been no suitable method to quantify blood flow distribution to large working and nonworking muscles involved in ergometer or treadmill exercise. METHODS AND RESULTS To quantify the redistribution of blood flow, we compared thallium activity in a bicycle pedal...

The main goal of this research project was to retest the validity of a specifically designed judo field test (Santos Test) in a different group of judokas. Eight (n=8) national-level male judokas underwent laboratory and field testing. The mean data (mean +/- SD) obtained in the laboratory tests was: HRmax: 200 ± 4.0 beats × min(-1), VO2 max: 52.8 ± 7.9 ± ml × kg(-1) × min(-1), lactate max: 12 ...

This study reviews the predictive value of maximum oxygen consumption (VO2max) and anaerobic threshold, obtained through cardiopulmonary exercise testing, in calculating peri-operative morbidity and mortality in non-cardiopulmonary thoraco-abdominal surgery. A literature review provided nine studies that investigated either one or both of these two variables across a wide range of surgical proc...

The objectives of the pilot study are to (1) confirm the general observation that an immune-supporting supplement, ASEATM, has an effect on athletic performance and (2) determine the specific physiological parameters: Heart Rates (HR), volume of O2 inspired (VO2), volume of CO2 expired (VCO2), volume of expired gas (VE), Respiration Rate (RR), Respiratory Exchange Ratio (RER), Aerobic Threshold...

Postoperative outcome is mainly influenced by ventricular function. Tests designed to identify myocardial ischemia alone will fail to detect cardiac failure and are thus inadequate as a screening test for identification of cardiac risk in noncardiac surgical patients. We find that the degree of cardiac failure is the most important predictor of morbidity and mortality. We use cardiopulmonary ex...
