Abstract: The purpose of this study was to determine the effects of tibial and foot position during step-up exercises and quadriceps setting on the muscle activity of the vastus medialis and vastus lateralis. Eighteen healthy subjects with a mean age of 21.2 years participated in this study. The silver-silver chloride surface electrodes were applied to the vastus medialis oblique (VM) and vastus lateralis (VL). Step-up exercises were performed in conjunction with one of three tibial positions (medial tibial rotation, neutral tibial rotation, lateral tibial rotation), and quadriceps setting with one of three foot positions (foot pronation, foot neutral, foot supination). Muscle activity of vastus medialis and the VM/VL ratio in the lateral tibial rotation were significantly greater than that in the other tibial positions during the step-up exercises. No significant differences were observed due to the foot position for vastus medialis, vastus lateralis and VM/VL ratio during quadriceps setting. These results suggest that foot position in quadriceps setting is less effective for the vastus medialis and the vastus lateralis muscle, and that step-up exercises accompanied by lateral tibial rotation can be the most effective for preferential recruitment of the vastus medialis relative to the vastus lateralis.
