Limited movement over an extended period of time, such as is seen with injury and postural deviations, can result in muscle shortening on one side of a joint and muscle lengthening on the other side of the joint. How do these length changes affect the force-generating capacity of these muscles?
a. The lengthened muscles generally have a higher force production throughout the full range of motion, as muscles are strongest when they are longest
b. The shortened muscles will produce the same amount of force as they did at normal length, only at a faster rate of movement
c. They will have greater force-generating capacity at their new lengths, but diminished force-generating capacity at normal resting lengths
d. They will have diminished force-generating capacity at their new lengths, but greater force-generating capacity at normal resting lengths.
