Abstract

The back squat exercise is a popular resistance exercise that involves synchronous movement of the entire body to perform the movement properly . The two main focuses when considering engaging in the back squat exercise are the risks of injury and the enhancement of performance. There is little information and scant understanding on the way body proportionality impacts the risk of injury and performance. The present study investigated this issue by investigating if there was a relationship between anthropometric ratios and kinematic & kinetic outcomes from the left and right hip when experienced, male back squatters performed a single repetition at 80% of 1RM load. Additionally, this study compared the kinematic & kinetic outcomes of the left and right hip.

The results of this study showed that amongst experienced, male back squatters, there was no relationship of kinematic and kinetic outcomes to the anthropometric ratios. The results did indicate that there were significant differences between the outcomes of the left and right hip in four of the twelve comparisons.

There was little variance amongst the anthropometric ratios of the subjects and they were an experienced group of back squatters. These two factors are believed to have impacted the results. Future studies could use subjects of more varied anthropometric ratios and subjects with less experience.
