摘要: The effects of a functional knee brace on local intramuscular pressures and calculated blood perfusion pressure in the tibialis anterior muscle legs six volunteers were determined. Torque generation during dorsiflexion ankle joint was measured with Kinetic Computerized ergometer, time to elicit fatigue exercise recorded. For each experimental subject studies compared right left unbraced legs, then braced finally legs. In leg, at rest relaxation significantly higher, 35% shorter. lower because increased pressure. We conclude that caused by is possible explanation for premature development leg.
