Introduction: The effect of exercise training on delaying the onset of vastus medialis oblique muscle versus vastus latralis muscle is important in preventing pain in the military population. The aim of this study was to investigate the effect of 16 weeks progressive exercise training on the delay in the activating vastus medialis oblique muscle into the vastus lateralis muscle during squatting and stepping down in the students of Imam Ali Military University.
Methods and Materials: The present resaerch is an experimental study. 100 students of Imam Ali Military University randomly divided into three control groups (n=37), progressive exercise training group (n=33) and progressive exercise training group + booster session (n=30). Then the training groups practiced for 16 weeks each week contain 3 sessions. Visual analog scale was used for electrical recording of muscle activity from the surface electromyographic device (sEMG) eight channels and assessing the intensity of pain from the visual scale of pain measurement (VAS).
Results: The results of the present study indicated that the mean time delay in the operation of VMO muscle to VL muscle decreased significantly (P≤0.05) in the groups that performed progressive exercise training. Moreover, the results of visual analog scale (VAS) test after intervention compared to before, showed a decrease in students’ pain score (P≤0.05).
Discussion and Conclusion: Advanced exercise, especially with a weekly booster session, reduced the time delay of VMO muscle activation and improved the temporal imbalance between internal and external wide muscle activity, which it could possibly be an indicator of reducing pain and infection in officer students Knee pain, especially PFPS.
