Research Abstract

Aim of this study is to prove whether adaptation of the neuromuscular system to in the early stage of resistance training will strengthen muscular force from type-1muscle fibers by mechanomyogram (MMG). Five subjects were employed high load and low frequency resistance training of this study, which period was 2weeks. Comparison of MMG patterns which were measured during isometric voluntary ramp contraction before and after the resistance training indicated that muscular force from type-1 muscle fiber was strengthened.
