Background: The study aims to compare how 3 balance platform designs affect ankle muscle activation during various functional exercises, all performed on the dominant limb. Methods: Fifteen healthy, active participants performed single-leg stance, single-leg squat, and forward lunge on BOSU (R) Ball, wobble board, stability trainer, and flat ground. Surface electromyography was used to measure Peroneus Longus, Tibialis Anterior, Gastrocnemius, and Soleus activation during these exercises on different platforms and flat ground. Repeated measures ANOVA with two factors (exercise and platform) were used for analysis. Results: There was a significant interaction between balance platforms and exercises (p < 0.05). Soleus displayed the highest activation amplitudes during the single leg stance and single leg squat on BOSU (R), and peroneus longus displayed the greatest activation amplitudes during the forward lunge on BOSU (R) (p < 0.05). Conclusions: The present study findings indicated that exercises conducted on a flexible platform resulted in greater muscle activation levels when compared to those executed on both a rigid platform and flat ground. Based on the level of ankle muscle activation in the current study, exercises for the ankle would progress from exercises on to a flat ground to on a BOSU (R) in order to achieve progressively greater ankle muscle activation. Level of evidence: Level III.
