Consider the schematic diagram below (Figure 1). This figure represents the joint angles produced by the lower limb of a young adult as they move from the seated to standing position. (a) We know that eccentric force decreases with age. Please draw a Force-Length curve for the knee flexor muscle group of i) a young adult and ii) older adult as they move through one sit to stand cycle: from SEATED to STANDING and back to a SEATED position. (b) Please draw a Force-Velocity curve for the knee flexor muscle group of i) a young and ii) older adult as they move through one sit to stand cycle: from SEATED to STANDING and back to a SEATED position. (c) Using information about age-related changes in muscle mechanics (muscletendinous Force-Velocity curves) and kinematics (Velocity), explain why aging may impact the performance of the Sit to Stand cycle for an older adult.
