Abstract
The aims of this study were to examine the muscle architectural, rapid force production, and force-velocity curve adaptations following 10 weeks of resistance training with either submaximal weightlifting catching (CATCH) or pulling (PULL) derivatives or pulling derivatives with phase-specific loading (OL). 27 re-sistance-trained men were randomly assigned to the CATCH, PULL, or OL groups and completed pre-and post-intervention ultrasound, countermovement jump (CMJ), and isometric mid-thigh pull (IMTP). Vastus lateralis and biceps femoris muscle thickness, pennation angle, and fascicle length, CMJ force at peak power, velocity at peak power, and peak power, and IMTP peak force and force at 100-, 150-, 200-, and 250 ms were assessed. There were no significant or meaningful differences in muscle architecture measures for any group (p > 0.05). The PULL group displayed small-moderate (g = 0.25 - 0.81) improvements in all CMJ variables while the CATCH group displayed trivial effects (g = 0.00 - 0.21). In addition, the OL group displayed trivial and small effects for CMJ force (g = -0.12 - 0.04) and velocity variables (g = 0.32 - 0.46), respectively. The OL group displayed moderate (g = 0.48 - 0.73) improvements in all IMTP variables while to PULL group displayed small-moderate (g = 0.47 - 0.55) im-provements. The CATCH group displayed trivial-small (g = -0.39 - 0.15) decreases in IMTP performance. The PULL and OL groups displayed visible shifts in their force-velocity curves; however, these changes were not significant (p > 0.05). Perform-ing weightlifting pulling derivatives with either submaximal or phase-specific loading may enhance rapid and peak force production characteristics. Strength and conditioning practitioners should load pulling derivatives based on the goals of each specific phase, but also allow their athletes ample exposure to achieve each goal.
