This study aimed to investigate the effect of stance width on lower limb muscle activation during lunge exercise. A total of 20 healthy adults with no musculoskeletal or neurological disorders participated in the study. The participants performed lunge exercises with two different stance widths, set at 50% and 70% of their leg length, for three repetitions each. Surface electromyography (EMG) was used to measure the muscle activation of the vastus medialis (VM), vastus lateralis (VL), rectus femoris (RF), and gluteus medius (GM) during both concentric and eccentric contractions. An independent t-test was conducted to compare the muscle activation between the two stance width conditions, with a significance level set at 0.05. The results showed no significant differences in muscle activation across the measured muscles between the 50% and 70% stance width conditions (p>0.05). These findings suggest that stance width does not have a substantial impact on lower limb muscle activation during lunge exercises. Clinically, this indicates that lunge exercises can be performed effectively without the necessity of a specific stance width, allowing for a more flexible approach based on individual comfort and stability. This study contributes to the understanding of lunge exercise mechanics and suggests that individualized adjustments in stance width may be appropriate in exercise prescription and rehabilitation programs.
