Aim: The aim of the study was to examine the effects of squat exercises performed on different surfaces on the activity of the Vastus Medialis Oblique (VMO) muscle.
Method: Forty healthy subjects performed squat exercises for five seconds each on three different support surfaces: concrete floor, foam, and rubber discs. As the subjects performed the squat exercises on each surface, data on the activity of the vastus medialis oblique was collected using electromyography.
Results: The activity of the vastus medialis oblique and was found to be statistically significantly higher (p<0.05) on rubber discs than when the squats were performed on concrete floor or foam.
Conclusion: The activation of vastus medialis obilique is more on unstable surfaces. Hence they are more suitable strengthening of VMO.
KEY WORDS: Vastus medialis oblique, Electromyography, Support surfaces.
