Session Title

Using a Sarcomere Model to Teach Skeletal Muscle Structure and Function

Session Format

Presentation Session (45 minutes)

Location

Room 1909

Abstract for the conference program

Many students struggle with the structure and function of the skeletal muscle contractile mechanism, the sarcomere; which is an integral part of a Physiology of Exercise course. This study looked at incorporating “in-class” construction of a working sarcomere model [using modifications on the model instructions set forth by Jittivadhna et al. (2009)] within an Exercise Physiology course, in conjunction with a lecture component on skeletal muscle structure and function. Objectives of the model construction were to have each student be able to successfully identify every component of the sarcomere as well as be able to successfully demonstrate the action of the sarcomere unit. Final assessment results from the model construction classes are compared to Physiology of Exercise classes that did not construct a working model, and solely utilized traditional lecture modalities. Session objectives will be to demonstrate construction and utilization of the sarcomere model and discuss how the model was used in class to assist with the student’s understanding of the structure and function of the sarcomere unit. The session audience will be invited to assist with construction and be able to examine the completed workable sarcomere units. Final assessment results will be compared and discussed during the session.
