Based on the length-tension relationship,
a. stretching a skeletal muscle 30% longer than the lo results in a greater contraction
b. varying the amount of overlap of thick and thin filaments does not greatly affect contraction force as long as tension remains the same
c. more tension develops if a muscle is 30% shorter than its resting length
d. muscle tension remains the same as long as the muscle's length is not more than ?30% of the resting length.
e. a resting muscle that is shorter or longer than its lo will generate less tension at the onset of contraction.
