A bigger diameter muscle

fibre can generate more tension because the thick filaments get thicker.

A muscle can generate more

tension when multiple motor units are recruited.

A sarcomere will not

develop as much tension when fully stretched, as there is less overlap between

the thick and thin filaments.

When

a whole muscle is stretched to its maximum, there is passive tension due to the

elastic elements of the muscle.

A

rapid series of muscle twitches can generate more tension than a single twitch.
