The effect of repeat exercise on pulmonary diffusing capacity and EIH in trained athletes

Article Abstract:

Post exercise measurements of pulmonary diffusion capacity may not accurately indicate pulmonary gas exchange and pulmonary fluid accumulation during exercise. Arterial oxygen saturation was shown not to change during a second test after exercise, suggesting any interstitial edema that developed was without clinical significance. Changes in pulmonary diffusing capacity may be due more to blood redistribution than to pulmonary edema.

Exercise performance in those having Parkinson's disease and healthy normals

Article Abstract:

Research indicates that individuals with Parkinson's disease are less likely to reach optimum cardiovascular levels via exercise than their non-afflicted counterparts. While there were no significant differences in maximal oxygen consumption between afflicted and non-afflicted subjects, the time factor differed in that afflicted subjects were unable to exercise for longer periods.

Control of skeletal muscle perfusion at the onset of dynamic exercise

Article Abstract:

Muscle vascular conductance and blood flow sharply rise at the beginning of exercise. Although the exact physiological mechanism of this higher blood flow is unknown, hyperemia starts and peaks within seconds of exercise onset. Researchers have dismissed neural, metabolic, endothelial, or myogenic explanations in favor of a mechanic factor.
