- A healthy 32-year-old man lifts weights regularly as part of his workout. In one of his biceps muscle fibers at rest, the length of the I band is 1.0 μm and the A band is 1.5 μm. Contraction of that muscle fiber results in a 10% shortening of the length of the sarcomere. What is the length of the A band after the shortening produced by muscle contraction? Draw the sarcomere before and after contraction.Microfilaments are long filamentous proteins made up of many globular proteins.

Muscle protein synthesis is a naturally occurring process in which protein is produced to repair muscle damage caused by intense exercise. It is an opposing force to muscle protein breakdown (MPB) in which protein is lost as a result of exercise.
