Abstract	The present study examined the relationships among physical characteristics, muscular strength, shoulder rotational strength, and explosive performance in college-level male powerlifters and weightlifters. Thirty male strength athletes with a minimum of two years of structured resistance training experience participated in the study. We assessed anthropometric and body composition variables, including body weight and lean body weight, along with 1RM back squat, bench press, deadlift, shoulder internal and external rotator peak torque at 60°/s, countermovement vertical jump height, and 1RM power clean performance. We used descriptive statistics, Pearson product-moment correlation, principal component analysis, and independent-samples t-tests to examine relationships and differences among variables. Lean body weight showed strong positive relationships with total 1RM strength (r = 0.84, p < 0.05) and 1RM power clean performance (r = 0.74, p < 0.05). Shoulder internal and external rotator peak torque were also significantly associated with total 1RM strength (r = 0.61 and 0.55, respectively). Principal component analysis identified three major dimensions: Absolute Strength and Mass, Upper-Body Stability, and Explosive Power. Powerlifters had significantly greater body weight, lean body weight, and total 1RM strength, whereas Olympic weightlifters achieved significantly higher vertical jump height and 1RM power clean performance. The groups did not differ significantly in shoulder internal or external rotator peak torque. The findings indicate that strength performance in collegiate lifters is multidimensional, with lean body mass and maximal strength being more prominent in powerlifting, while explosive performance characteristics are more evident in Olympic weightlifting.
