Summary Introduction

To review:

The process used for the conversion of isometric contraction into isotonic contraction by the involvement of motor unit recruitment and the series elastic components of muscle.

Introduction:

Isometric contractions occur when the opposing force (load) is greater than the tension of muscle. The length of the muscle does not change in this type of contraction. The involvement of large number of muscle fibers for the strong contraction of muscle is known as motor unit recruitment and the contraction of muscle is attached to the series elastic components.
