studies on single cardiac cells have already given insight into the characteristics of 1 ) sarcomere shortening and extension at essentially zero external force , 2 ) sarcomere shortening during auxotonic force development , 3 ) the contribution which the cell makes to the resting tension-sarcomere length relationship of intact cardiac tissue , and 4 ) the sarcomere length-dependency of the force generating capacity of cardiac muscle during twitch contractions .
