INTRODUCTION:::

When a muscle contracts against a load, it performs work. During this, energy is transferred from the muscle to the external load to lift an object. The energy that is required to perform the work is due to chemical reactions in the muscle cells during contraction. Muscle contraction depends on energy supplied by ATP.
