The purpose of the present study was to investigate the relations between force and time to peak force or force developing speed during various levels of the fastest isometric volntary contractions on several muscle groups. Force curves of knee extension, knee flexion, and elbow f1exion were recorded on 17 ma1e subjects during maximal (MVC) and submaximal force which were exerted as fast as possible. Then, peak force, time to peak force, and force speed were measured. Larger MVC muscle grups tended to take longer time to reach MVC among those three muscle groups. The significant relation between MVC and time to MVC was obtained in knee flexion and elbow flexion but not for knee extension. The relation between force and time to peak force was changed at 50% of MVC. Though the time to peak force was almost constant below 50% of MVC, the time to peak force increased with increment of force amplitude above 50% of MVC. Though force speed increased with increment of peak force, this relation changed at approximately 50% of MVC. The increment was less in the force speed accompanied with force increment above 50% of MVC. From these results for the examined muscle groups, it was concluded that change courses of time to peak force and force speed which accompanied with force graduation were different between be1ow and above 50% of MVC when the fastest isometric voluntary contractions were performed. It was suggested that different modes of central mechanism would be operative between below and above 50% of MVC.
