Reebok Core Boards used as a platform in training provide an unstable environment for resistance training. The objective of this study was to examine the effect of unstable surface on muscle electromyographic (EMG) activities during a deep squat task. Thirteen male subjects participated in the study. EMG activities of soleus (SO), vastus lateralis (VL), vastus medialis (VM), rectus femoris (RF), biceps femoris (BF),gluteus maximus(GMa),gluteus medius(GMe), and upper lumbar erector spinae (ULES) muscles were collected when subjects were performing a deep squat task on a Reebok Core Board and ground with different weight loads (body weight, 30%RM, 60%RM). No significant difference was observed for all muscle EMG between unstable and stable surface during all weight load conditions (p > 0.05). Muscle EMG significantly increased when the weight load increased (p < 0.05 ). Similar muscle activities were observed when subjects performed a deep squat task on a stable and unstable surface. Simply applying unstable surface might not provide extra stimulation to the superficial muscles during squatting in resistance-trained students.
