The impact of exercise training on sympathetic activation is not well understood, especially across untrained and trained limbs in athletes. Therefore, in eight sedentary subjects (maximal oxygen consumption = 40 +/- 2 ml x kg(-1) x min(-1)) and eight competitive cyclists (maximal oxygen consumption = 64 +/- 2 ml x kg(-1) x min(-1)), we evaluated heart rate, blood pressure, blood flow, vascular...

Ventilatory gas exchange during exercise was compared in patients with mild asthma (11 females and 11 males), hyperventilation syndrome (HVS, 11 females), and healthy subjects (11 females and 11 males) in order to assess hyperventilation during exercise and its association with exercise-induced bronchoconstriction. The asthmatics showed decreased working capacity and decreased maximal oxygen co...

The purpose of this study was to determine the relationship between selected anthropometric and physiological variables and 10K time. Eleven male wheelchair athletes with spinal cord injuries in training for national competition performed continuous progressive exercise tests on a wheelchair ergometer to determine maximal metabolic and cardiorespiratory values. Anthropometric data were also col...

Misonidazole, a 2-nitroimidazole, has been shown to form metabolically induced adducts to cellular molecules at a very high rate in the absence of oxygen, and this rate decreases substantially as the oxygen concentration increases. Thus, it has considerable potential as a marker for hypoxic, radiation resistant cells in tumors. The dependence of the rate of adduct formation (binding) on oxygen ...

This study was designed to determine the differing cardiorespiratory responses between maximal treadmill ('I'M) and cycle (CY) ergometry, and the reliability and variability of these responses in 46 children 7 to 9 years old (23 boys and 23 girls). Two maximal TM and two maximal CY tests were administered, as well as a body composition assessment. The TM resulted !n a 9.4%, 11.1%, and 10.2% hig...
