Skeletal muscle length-tension relationship

Cjeneral concepts of transfemoral socket design include (1) proper contouring to facilitate remnant muscle function, (2) stabilized force application so as to apply load to the skeletal structures as much as possible, (3) stretching the hip muscles for improved functionality (i.e., length-tension relationship for muscle ), (4) maximized contact area so as to minimize soft tissue pressmes, and (5) adequate contact between the distal limb and socket walls so as to prevent edema. 

Describe the factors that influence the strength of skeletal muscle contraction including multiple motor unit summation, asynchronous motor unit summation, frequency of nerve stimulation, length-tension relationship, and diameter of the muscle fiber... 

The structure of the contractile unit is fundamental to the interpretation of the relationship between muscle length and isometric tension in skeletal muscle. Each sarcomere unit contains bipolar thick filaments with a central bare zone surrounded by pairs of actin filaments of opposite polarity. The actin filaments are anchored at Z-bands that are aligned in parallel. The length-tension behavior of skeletal muscle has been interpreted in terms of changes in the overlap between the thick eind thin filaments as...
