The purpose of this study was to investigate the effect of combined viscous and elastic load training using a variable mechanical impedance device.【Method】 Sixteen healthy men trained maximal concentric elbow flexion of right arm 3d-wk^<-1> for 8 weeks. Isoviscous training group performed 6 sets of 12 on a developed impedance device. Similarly, Combined training group performed 6 sets of 8-10 maximal concentric actions. Isoviscous, isokinetic and isometric strength were measured three times. The muscle volume of the biceps brachii and brachialis were measured by magnetic resonance (MR) images of upper arm at before and after training. 【Result】 Muscle strength and power significantly increased after 8 weeks training, but no significant changes between groups. The muscle volume also significant increased after 8 weeks training, but no significant change between groups.
