a Sarcomere dynamics of the center (trace A) and end regions (trace B) of a single skeletal muscle fiber. Fiber length = 5.47 mm . Center region = 2.03 mm from right tendon. End region = 0.32 mm from right tendon. Temperature = 12 °C Calibration bars for tension record: horizontal = 100 ms, vertical = 50 mg. (From: [13]. b The hypothetical muscle length-force-velocity surface for skeletal muscle. Shaded regions represent a “slice” of the surface at either constant length or velocity. A “slice” of the surface at constant length is simply a force-velocity curve measured at that length while a “slice” of the surface at constant velocity is simply a length-tension curve measured at that velocity (compare with Figs. 2, 3, 4).
