Abstract
BACKGROUND
The barbell back squat is one of the most performed exercises, being important for the strengthening of lower limbs and trunk. Recently, it has become popular to train under different conditions of footwear or without it, and some investigations have analyzed the changes that this brings, with some contradictions in this regard. The purpose of this study was to analyze the kinematic variations under different shoe conditions (running shoes, barefoot and barefoot with heel raised) in the back squat in female university athletes.
METHODS
Fifteen athletes in the three conditions with a load equal to 70% of their one-maximum repetition (1RM), were recorded and analyzed to determine the angles of the ankle, knee, hip and trunk by five movements in each condition.
RESULTS
The use of enhancement significantly increased (P<0.05) the dorsal flexion angle of the ankle, against the footwear condition and barefoot without enhancement (109.6±11.1° vs. 99.1±9.0° vs. 101.3±11.5°). No significant differences were observed in any of the other variables.
CONCLUSIONS
An optimal squat technique is important for preventing injuries, optimal rehabilitation and for improving sports performance. Increased dorsal ankle flexion angle may protect distal tibiofibular joint.
