Background: Kicking actions have been implicated in the aetiology of soccer injuries, and the unilateralnature of kicking may influence this. The aim of the current investigation was to determinewhether soccer players exhibit bilateral differences in support limb patellar tendon loads. Material/Methods: Fifteen male soccer players were examined whilst kicking a stationary soccer ball with both their dominant and non-dominant feet. Patellar tendon kinetics were obtained from each limb and then contrasted using paired samples t-tests. Results: Significant increases in patellar tendon kinetics were found when using the non-dominant limb. Conclusions: The findings from the current investigation have clinical significance and support the notion that kicking with the non-dominant limb may be associated with increased risk for patellar tendon injury aetiology.

The aim of the current investigation was to examine the influence of the front and back squat variants on the hamstring and the quadriceps muscles kinematics. Eighteen male participants were recruited with 1 repetition maximum values of 122.7 ±16.4 and 88.7 ±13.9 kg for the back and front squat lifts. Participants completed both back and front squats at 70% of their front squat 1 repetition maximum. The hamstring and the quadriceps muscle kinematics were determined during kinetic situations using motion capture data, in addition to segmental and joint kinematics. Differences between squat conditions were examined using paired samples t-tests.The results showed that there were no differences in either segmental/joint or muscle kinematics between the front and back squat lifts. These findings lead to the conclusion that neither the front nor the back squat conditions differ in terms of their eccentric and concentric recruitment of the quadriceps and hamstring muscles.

Background: A primary technique in the discipline of strength and conditioning the squat has two principal ‘back and front’ variants. Despite the physiological and strength benefits of the squat, the propensity for musculoskeletal injury is high. The current investigation examined the influence of the front and back squat variations on the load experienced by the Achilles tendon. Material/Methods: Achilles tendon loads were obtained from eighteen experienced male participants as they completed both back and front squats. Differences between squat conditions were examined using Bonferroni adjusted (p = 0.0125) paired t-tests. Results: The results showed that the peak Achilles tendon load was significantly greater in the back squat (2.67 ±0.74 B.W) condition compared to the front squat (2.37 ±0.69 B.W). Conclusions: Given the proposed relationship between the magnitude of the load experienced by the Achilles tendon and tendon pathology, the back squat appears to place lifters at greater risk from Achilles tendon injury. Therefore, it may be prudent for lifters who are predisposed to Achilles tendon pathology to utilize the front squat in their training.
