Summary Introduction
To analyze:
The difference between training regimes for a sprinter and marathon runner and its reason too.
Introduction:
Muscles are the tissue in the body that is fibrous in nature. These play a key role in contraction that helps in the movement. The muscle cells have myofibrils that help the muscles to carry out their function. There are three types of muscles, namely, the smooth, skeletal, and cardiac muscles. The skeletal muscles can have two types of fibers, slow twitch, and fast twitch fibers.
