Fiber type area and metabolic potential of the thigh muscle in man after knee surgery and immobilization.

摘要: The muscle atrophy of the quadriceps was investigated in patients after knee operations and immobilization a long leg plaster cast. Muscle biopsies were taken before operation 5 weeks immobilization. activity oxidative (SDH) glycolytic (PFK) enzymes determined. fiber area different types measured enzyme activities single characterized fibers analyzed. A selective type 1 found with reduced cross-cut fiber, occurred slow-twitch fibers. effect tension immobilized inhibiting role postoperative pain is discussed.
