ABSTRACT
Toji, H., and M. Kaneko. Effect of multiple-load training on the force-velocity relationship. J. Strength Cond. Res. 18(4):792–795. 2004.—The effect of training with a combination of different loads (multiple-load training) on the force-velocity and force-power relationships was examined with training programs that included maximal isometric contraction (Fmax) and concentric contraction of the elbow flexor muscles. Twenty-one male college students were placed into 3 equal training groups (G30 + 60, G30 + 100, and G30 + 60 + 100) and performed multiple-load training 3 days per week for 8 weeks. The training load was a set fraction of the maximal isometric strength (% Fmax). The G30 + 60 group performed 6 repetitions of elbow flexion at 30 and 60% Fmax. The G30 + 100 group performed 6 repetitions at 30% Fmax and six 5-second Fmax loads. The G30 + 60 + 100 group performed 4 repetitions at 30 and 60% Fmax and four 5-second Fmax loads. After training, Fmax and maximal velocity significantly increased (p < 0.05) in all 3 training groups. The increases in maximal power were significantly (p < 0.05) different between the G30 + 60 + 100 group (52.9%) and the G30 + 100 group (24.2%). These results suggest that multiple-load training programs with 4–6 repetitions are effective for improving muscle power and velocity of the elbow flexors.
