Evaluate possible adaptations bring from resistance training clustered series in lower members of elderly. Methods: Seventeen seniors untrained, being them ten womans and seven mans, followed a training program with 24 sessions to develop muscle power, the group were subjected a teste of 1 maximal repetition (1RM) for control of load and isokinetic dynamometer to evaluate the torque at three velocities: isometric, 60° and 180° in movements of extension and flexion. A repeated measures Student's t test to analyze the effect between the two periods. Results: At the final of the twenty-four sessions was possible to observe improvement in torque in the comparison of pre and post of the group, then presented significant improvement in measure of knee extensor isometric strength, in flexural strength at 60°/s and maximal extensor force all then presenting P<0,005 and both with intermediary effect. When the female gender was evaluated its possible note significant increase on the test of 1RM, presenting P<0,005 and with great effect, in the other hand masculine gender shows significant difference in knee extensor isometric strength and flexure strength 60°/s, showing P<0,005 and both with great effect. Conclusions: Based on assessment of knee extensor and flexor muscles, was possible watch the following conclusions, resistance training clustered series promoted great increases specifically on knee extensors on both groups.
