background: consumption of energy drinks has become widespread among athletes. the effectiveness of red bull and hype energy drinks on selected indices of maximal cardiorespiratory fitness and blood lactate levels in male athletes was examined in this study. methods: ten male student athletes (age: 22.4 ± 2.1 years, height: 180.8 ± 7.7 cm, weight: 74.2 ± 8.5 kg) performed three randomized maxim...

although sport-physiologists have repeatedly analyzed respiratory gases through exercise, it is relatively new in the cardiovascular field and is obviously more acceptable than standard exercise test, which gives only information about the existence or absence of cardiovascular diseases (cvds). through the new method of exercise test, parameters including aerobic and anaerobic are checked and m...

A b s t r a c t 4 . Oxygen consumption. ventilation frequency and tidal volume were measured simultaneously in two lizards, Varanus pouldii and Sauronrabts hispidus, during rest and maximal activity. 2. Ventilation frequency m d tidal volume are almost identical in these species. The grcater oxygen consumption during activity of Varanus results from a grcater oxygen extraction from ventilated a...

background: maximal volume oxygen is an accepted standard for measuring cardiorespiratory readiness. this factor indicates the power of physiological adoption for increasing activity time and efficiency of cardiovascular system. the objective of this study was to find out an optimal correlation between maximal volume oxygen and maximal voluntary ventilation indicators and their effect on cardio...

STUDY DESIGN This is a randomized comparison of three exercise tests in a sample of 30 patients with chronic low back pain. OBJECTIVES To determine, by comparing three exercise tests, which test yields the highest peak and predicted oxygen consumption in a sample of patients with chronic low back pain. SUMMARY OF BACKGROUND DATA Little is known about the level of aerobic fitness in patients...

We investigated differences in walking (80 m/min) and running (147 m/min) economy [submaximal oxygen consumption (VO(2) (submax))] between adolescent girls (n = 13; age = 13.3 +/- 0.9 yr) and young women (n = 23; age = 21.0 +/- 1.5 yr). Subjects were matched for height (158.7 +/- 2.9 cm) and weight (52.1 +/- 3.0 kg). Anthropometric measures (height, weight, breadths, skinfolds) and preexercise ...

PURPOSE Cell death in neurodegeneration occurs at the convergence of diverse metabolic pathways. In the retina, a common underlying mechanism involves mitochondrial dysfunction since photoreceptor homeostasis and survival are highly susceptible to altered aerobic energy metabolism. We sought to develop an assay to directly measure oxygen consumption in intact retina with the goal of identifying...

Monitor lizards (Varanus exanthematicus) were used to examine the prioritization or additivity of the metabolic responses associated with exercise and digestion, either of which can elevate metabolic rate independently. Rates of oxygen consumption (V(O2)) and ventilation (V(E)) were measured in lizards during fasting exercise, postprandial rest and postprandial exercise. In fasting animals, V(O...
