Introduction
The bicep muscle is located on the front part of the upper arm and is attached to the arm bones by tendons. When biceps contract, the form arm is pulled up and will rotate outward1. The pronator teres muscle is located on the palmer side of the forearm, below the elbow, and its function is to rotate the forearm palmdown2. The bicep brachii and pronator teres muscles are examples of skeletal muscle. Skeletal muscle contains multiple nuclei, myofiber and has fast muscle contraction. Skeletal muscle contains no gap junctions and hormones cannot excite muscle contractions, unlike smooth and cardiac muscle. Skeletal muscle contains thick filaments, thin filaments, myosin, actin, and sarcomeres. The site of calcium action, in skeletal muscle, is troponin According to the Oxford Dictionary3, endurance is defined as “the fact or power of enduring an unpleasant or difficult process or situation without giving way” and strength is defined as “the quality or state of being strong”. As it relates to physiology, muscle endurance is the capability of a muscle to endure multiple contractions against a resistance for a prolonged amount of time5, while muscle strength is the amount of force a muscle can produce with a single maximal effort4. When muscles contract they go
