Description

<p>Objective: The purpose of this study was to determine the effect of thigh compression sleeves on muscle stress by measuring shear modulus of the muscle during external compression at various compression and contraction intensities.</p><p>Methods: The participants in this study were 14 healthy young males with rectus femoris in their right leg. Compressive strength was measured under three conditions: control (no compression), 20 mmHg, and 40 mmHg. The contraction strength was set to 0 percent, 30 percent, and 60 percent of the maximum knee extension muscle strength in the control condition, which was measured beforehand. A gradually increasing knee extension exercise task was then performed. The Measurement point was set at 50 percent of the thigh length.</p><p>Results: A main effect of compression intensity was observed on the elastic modulus, but there was no significant interaction. Post-test results revealed a significant decrease in elastic modulus at 20 mmHg compared to the control condition (p<0.05).</p><p>Conclusion: Using compression sleeves at 20 mmHg was suggested to reduce the muscle stress induced by muscle contraction.</p>
