To determine: The type of fiber that is present in a disproportionate amount in Person S.
Introduction: The muscles that are present in the skeletal system are called skeletal muscles. Skeletal muscle tissues have long cells and striations. The cells present in the skeletal muscle tissues are multinucleated. The skeletal muscles help in the voluntary movement of the bones.
To determine: The ways by which the fiber helps in explosive and short-duration activities to Person S.
Introduction: In the given case, Sean and Person S are neighborhood friends that are athletes. Sean becomes a soccer player because he can overcome fatigue for a long time while Person S becomes a baseball player because he is explosive in shorter duration events.
