Title: Kinematic and dynamic characteristics of straight punches in elite male boxers Objectives: The purpose of this study was to quantify lower limb forces in the x, y, and z directions and their association with jab and cross relative peak force, and jab and cross peak velocity. Methods: A sample of 12 elite male subjects participated in the present study, which took place over two days. Subjects were familiarized with the procedures during the first day. During the second day, the subjects performed a standardized warm-up protocol, followed by one straight punch with the rear and then the lead hand to a force plate that was suspended in the air at the chin level by a cable system. The subjects were standing on two separate tri-axial force plates. Punch velocity was assessed using a Qualisys Motion Tracking Manager, where the marker used was placed in the middle of 12 OZ gloves. Results: Subject body weight resulted in a high positive significant correlation with jab and cross peak force, and a non-significant low and moderate positive correlation with jab and cross peak velocity, respectively. Partial correlation controlling for bodyweight resulted in a very high positive significant correlation between jab peak velocity and jab peak force and a high positive, but the non-significant...
