Table 1 Basic Musculoskeletal Design Parameters Affecting Muscle Function

From: Robot-assisted assessment of muscle strength

Muscle Property Affected Design Parameter
Maximum force, tension, and moment Physiological cross sectional area (number of parallel sarcomeres)
Areal distribution of muscle fiber types
Force Pennation angle
Fatigability Fiber type distribution (number and area)
Maximum moment Moment arm
Velocity of excursion Muscle fiber length (total number of serial sarcomeres) 
Areal distribution of muscle fiber types
Submaximum force at given shortening velocity Muscle fiber length
Range of Motion Muscle fiber length
Tendon length
Damping, energy storage Tendon length
Relative stiffness of a muscle-tendon unit Tendon length/muscle fiber length
Relative muscle-joint properties Fiber length/moment arm
