Adaptations to explosive resistance training with partial range of motion are not inferior to full range of motion

We tested whether explosive resistance training with partial range of motion (ROM) would be as effective full ROM using a noninferiority trial design. Fifteen subjects strength experience took part in an explosive—concentric only—leg press program, three times per week for 10 weeks. One leg was randomly assigned to exercise (ie, 9º) and the other ROM. Before after training, we assessed performance, isokinetic concentric isometric knee extension torque, vastus lateralis muscle architecture. Overall, both modalities increased maximal rate force development. Training yielded noninferior results compared peak power (+69 ± 47% vs. +61 64%), (4-6 6%-12% 1-6 6%-10% at 30, 60, 180?s-1), torque 100 (47 24 35 22) 150 ms (57 22% 42 25%). The comparison inconclusive functional parameters (300?s?1), joint angle 50 ms, electrically evoked torque) fascicle length thickness, although established pennation angle. However, not found statistically inferior any measured variable. Under present conditions, effects heavy were independent Instead, these data suggest that distinct timing work contractions confers more influence starting than on adaptations this type training.
