Purpose The purpose of this study was to compare the effects of supine lying with and without legs elevation on knee muscle recovery after plyometric exercise.
Methods Sixteen low-active healthy males were randomly allocated to supine lying with legs elevated 45 degree (n=8) or a supine lying (n=8) position for 30 minutes per day that lasted 5 days after completed 100 drop jumps from a 0.6-m box to induce muscle soreness. Indirect indices of muscle soreness (Pain scale, Peak torque, Hamstring/Quadriceps ratio) were assessed before and 24, 48, 72, and 96 hours post-exercise.
Results Supine lying with legs elevated position showed statistical significant difference in peak torque of knee extensor by 96 hours compared with supine lying position. (p<0.05) However, there were no statistically significant differences in time between groups throughout the recovery period on pain scale and Hamstring/Quadriceps ratio variables.
Conclusions Supine lying with legs elevated tends to attenuate the sign of delayed-onset muscle soreness of knee extensor following plyometric exercise compared with supine lying position.
