Determination of the velocity associated with VO(sub)2max

Article Abstract:

Results demonstrate that the oxygen consumption velocities in runners are significantly different. Data also indicate that after exercise blood lactate concentrations are similar at velocities close to maximal oxygen consumption rate velocity.

Use of bioelectrical impedance analysis to estimate body fluid compartments after acute variations of the body hydration level

Article Abstract:

Estimating body fluid compartments by using bioelectrical impedance analysis (BIA) after acute variations of the body hydration level is discussed. BIA was found to only half-predict body water loss after exercise even with standardized conditions. Differences in body temperature cannot explain such an unexpected result. The study of plasma osmolality and sodium concentration does not explain it either. More study would be needed to establish validity of using BIA to measure changes and to interpret extracellular water changes.

Fluid-regulatory hormone responses during cycling exercise in acute hypobaric hypoxia

Article Abstract:

The responses of fluid-regulating hormones during exercise in acute hypobaric hypoxia are described. Hypothesis that fluid-regulations are dependent on the relative intensity of exercise rather than the absolute workload is also described.
