Differences in Rate of Force Development, Muscle Morphology and Maximum Strength between Weightlifters and Track and Field Throwers

The purpose of this study was to investigate the differences between weightlifters and track field throwers in terms rate force development (RFD), lean mass, muscle architecture one-repetition maximum (1-RM) strength. Sixteen elite male athletes (eight eight throwers) participated study. Measurements were performed one week after annual national championships included anthropometry, body composition analysis (dual X-ray absorptiometry), vastus lateralis (VL) (ultrasonography), countermovement jump (CMJ), leg press isometric RFD 1-RM strength snatch back squat. similar groups (p > 0.05), although relative mass higher for < 0.05). Throwers had a trunk compared = 0.007). Weightlifters longer VL fascicle length 0.037). Performances CMJ height, power Lean index correlated with squat (r 0.667) 0.498). significantly 0.631) 0.718). These results suggest that may produce greater outputs than throwers, which be associated length.
