[Reduced lung function parameters after physical exertion in Austrian Alps in ozone concentrations below the legal warning limit].

The ambient ozone concentration has increased greatly over the past decades, which may lead to environmental health problems, especially during the summer. WHO guidelines recommend an 8 hour mean value of < or = 60 ppb ozone without health risk. The aim of the present study was to investigate if elevated zone concentrations at moderate altitudes in the Austrian Alps, characteristic of the situation in the summer months, influence pulmonary function after physical exercise.

Fluid regulation during prolonged physical strain with water and food deprivation in healthy, trained men.

The aim of this study was to investigate fluidregulating mechanisms, with special regard to the role of plasma proteins in the control of plasma volume (PV), and the role of the superficial tissues as a water storage organ of the body during prolonged physical strain. 29 male subjects (mean age 22.2 +/- 2.

Erythropoietin in 29 men during and after prolonged physical stress combined with food and fluid deprivation.

The study investigated the influence of prolonged physical stress during survival training with food and fluid deprivation on the serum concentrations of erythropoietin (EPO). A group of 29 male subjects [mean age 22.2 (SD 2.
