The Difference Between Back Squatting with a Straight Barbell Versus a Titan Safety Squat Bar: The Effect On 1-Repetition Maximum Values, Power Output, And Muscle Activation

Conflicting evidence exists on whether there are differences in muscle activation between squatting with a straight barbell (SB) or safety squat bar (SSB) during the back squat movement, and no study to date has investigated the power outputs of the ankle, knee, and hip joints between the variations (SB vs SSB). The study aimed to determine if using a safety squat bar will result in similar responses to the straight barbell when training. Twelve resistance-trained participants with prior SSB experience performed back squats using both a SB and SSB at 65% of 1RM and 85% of 1RM for a total of 12 repetitions. There was a significant difference between participants’ 1RM for SB compared to SSB. An eight-camera VICON motion capture system captured movement parameters and EMG data was recorded bilaterally for the vastus lateralis and semitendinosus. A multivariate ANOVA (Bar Type x Phase) showed there were significant differences in power output at the ankle joints and hip joints at 65% of 1RM and 85% of 1RM. An independent t-test showed no differences in muscle activation between SB and SSB. The Titan safety squat bar can be beneficial for individuals who cannot tolerate placing a straight barbell on their back.
