Effects of front and back squat techniques on patellofemoral joint kinetics in males

J Sinclair, S Atkins, N Kudiersky, PJ Taylor, H Vincent


Purpose: The barbell squat is fundamental in strength and conditioning, with two principal variants; the back and front squat. Unfortunately, the propensity for injury is high particularly at the knee. The aim of the current investigation was examine the influence of front and back squat variations on patellofemoral joint load.

Methods: Patellofemoral loads were obtained from thirty-five experienced male participants, who completed both back and front squats at 70% of 1 RM. Differences between squat conditions were examined using Bonferroni adjusted
(P = .008) paired t-tests.

Results: The results showed that significant differences (P < .008) in patellofemoral load were identified between both conditions with the highest load being experienced during the back squat exercise.

Conclusions: Given the proposed relationship between the magnitude of the load experienced by the patellofemoral joint and associated injury pathology, the back squat appears to place lifters at greater risk from injury. Therefore, it may be prudent therefore for lifters who are predisposed to patellofemoral pain syndrome to utilize the front squat in their training.
