Summary Introduction

To describe:

The relative forces of contraction that can be developed in individual’s back muscle when he bends at the knee to life an object and when he bends at the waist to lift an object, based on the length-tension relationship and also its significance.

Concept introduction:

The factor that influences the value of tension generated by a muscle when stimulated is the value of overlap of thin and thick filaments when the muscle starts its contraction. This principle is known as length-tension relationship.
