abstract="Shoulder joint injuries are common for professional firefighters. A potential cause of shoulder injury is an imbalance between anterior (push) and posterior (pull)  shoulder joint musculature. Understanding what contributes to these imbalances may  help to identify areas needing improvement. The purpose of this study was to  investigate different push to pull (P2P) ratios and the relationships among common  upper body fitness assessments, body composition, and push to pull (P2P) ratios in  firefighters. Thirty-three professional firefighters completed the following testing  protocol: one-repetition maximum (1RM) bench press, pull-up repetitions to failure,  push-up repetitions to failure, and a body composition assessment. The endurance P2P  (eP2P) was computed by dividing the number of push-up by pull-up repetitions, while  strength P2P (sP2P) was the relative 1RM divided by pull-up repetitions. Bivariate  relationships among variables were assessed with correlation coefficients and linear  regression assessed association between eP2P and sP2P (p ≤ 0.05). The sP2P and eP2P  were not associated (R (2) = 0.032, p = 0.99). Strength P2P was related with bench  press 1RM (r = 0.80) and push-ups (r = 0.40). Endurance P2P was related with pull-up  repetitions (r = -0.62), body fat percentage (r = 0.40), and fat mass index (r =  0.34). The results of the present study suggest sP2P and eP2P ratios should not be  used interchangeably. To improve sP2P and eP2P for firefighters, it is recommended  to improve the strength of anterior and posterior upper body musculature,  respectively, and reduce total body fat mass.<p /> <p>Language: en</p>",
