Is Inertial Training More Effective Than Conventional Strength Training?

The data concerning the efficacy of inertial training vs conventional strength training are contradictory. The aim of the study was to compare the impact of inertial training and body building training on elbow flexors and knee extensor strength. Twenty-six young untrained men were randomized to the inertial training (IT; n = 13) or body building group (BBT; n = 13). Both groups performed strength training three times a week for 6; IT - inertial training, BBT - body building training. Each training session included 12 exercise sets involving the elbow flexors and knee and extensors muscles worked separately (3 sets per single muscle group). The training loads were 70% of 1RM for the upper and lower extremities. Before and after training, the maximum force of trained muscles was evaluated under training conditions (one repetition maximum - 1 RM and maximal force under inertial conditions - IFmax) and under isometric conditions (MVT). Moreover, CMJ, SJ, pull-up test, circumferences of the limbs were also evaluated.
