T/F Consider the length-tension relationship. Then, click and drag each statement into the correct box to identify whether that statement is true or false regarding the length-tension relationship of muscles.
True:
A higher possible number of cross-bridges means higher tension.
For max hamstring contraction, begin with the knee fully extended.
Sarcomeres will achieve virtually no contraction if beginning at half length.
False:
For max tension from biceps, begin with elbow bent at 90 degrees.
For max contraction tension, begin with zero degree of overlapping thick and thin filaments.
The highest tension can be achieved if all possible cross-bridges are formed prior to stimulation.

True - Sarcomeres will achieve virtually no contraction if they begin at half their optimal length.

TRUE

Sarcomeres will achieve virtually no contraction if they begin at half their optimal length

For maximum hamstring contraction, begin with the knee fully extended

FALSE

The highest possible tension can be achieved if all possible crossbridges are formed prior to stimulation (A sarcomere is the basic contractile unit of muscle fiber)

A higher possible number of cross bridges means higher possible tension.
