Summary Introduction
To analyze:
The composition of muscle tissue in gastrocnemius muscle in athletes.
Introduction:
The gastrocnemius muscle is the type of muscle which is located on the back portion of the lower leg. It is the larger calf muscle. It possesses a high proportion of fast-twitch fibers. It has a medial head and a lateral head which are supplied with the artery.

A researcher is investigating the composition of muscle tissue in thegastrocnemius muscles (in the calf of the leg) of athletes. She takesa needle biopsy from the muscle and determines the concentration(or enzyme activity) of several substances. Describe the major differences this researcher sees when comparing the muscles of athletes whoperform in the following events: 100-meter dash, weight lifting, and10,000-meter run
In an isometric contraction, how can the muscle stay the same length when the muscle is contracting? Can choose more than one
- The muscle is not able to generate more (or the same amount) force than the load, preventing shortening of the muscle.
- Calcium stops entering the sarcoplasm when the desired length is reached.
- Elastic elements of the muscle stretch in response to the contraction of the muscle, so that the muscle stays the same size despite shortening sarcomeres.
- The myosin heads detach from actin when they reach the desired length.
The muscles of a recently deceased human can remain in a contracted state, termed rigor mortis, for several
hours, due to the lack of ..
