Most of increases in energy metabolism are induced by exercise. They are related with power and efficiency. In cycle ergometer exercise efficiency is positively correlated with exercise power and negatively correlated with pedaling rate. Ramp exercis

10.1152/japplphysiol.00630.1999.—Some recent studies of competitive athletes have shown exercise-induced hypoxemia to begin in submaximal exercise. We examined the role of ventilatory factors in the submaximal exercise gas exchange disturbance (GED

We have previously reported a reduction in exercise-induced hypoxaemia following polyunsaturated fatty acid supplementation (PUFA). Although this might have been explained by increases in membrane fluidity, a clear explanation could not be provided d

To describe the time course of plasma volume alterations and the changes in the plasma concentrations of hormones regulating water balance in relation to a marathon race, six experienced marathon runners (five men, one women) aged 28 (SD 6) years wer

Exercise-induced hypoxaemia (EIH) has been associated with an oxygen diffusion limitation. Because polyunsaturated fatty acids (PUFA) administration can modify cell membrane fluidity, we hypothesized that the importance of EIH could be reduced after

During both the cool and hot periods of the dry season of the Sahelian climate, sleep patterns of four African sportsmen from Niger (23 +/- 0.8 years old) were studied after square-wave cycle ergometer exercise. The sleep patterns were studied in the

The aim of this study was to test (a) three methods to estimate the quantity of lactate accumulated (QLaA ) in response to supramaximal exercise and (b) correlations between QLaA and the nonoxidative energy supply assessed by the accumulated oxygen d

A simple device for three-dimensional recording of human movement was developed. It consisted of four rigid bars linked together by three joints. At each joint an optical transducer, connected to a PC computer via an electronic interface, measured th
