Intramuscular pressures and muscle metabolism after short-term and long-term exercise.

Intramuscular pressures were measured in the anterior tibial and deep posterior muscle compartments in eight healthy individuals before, during, and after short-term exercise and in 38 individuals after long-term exercise by the wick catheter method. Muscle biopsies were also taken and analyzed for muscle fiber distribution, water content, and lactate content. There were no elevations of the intramuscular pressures in the anterior tibial and the deep posterior muscle compartments after exercise nor was there any evidence of edema or anaerobic metabolism in the muscles examined.
