Fig. 8.

Power and work developed in the MTU during contractions without and with a simulated anatomical catch mechanism. (A) Anatomical catch mechanisms substantially increase the peak power output. Dotted line indicates the peak isotonic power output of the muscle. (B) Anatomical catch mechanisms sometimes (low loads), but not always (intermediate loads), result in high net work outputs. Asterisks indicate significant difference (post hoc paired t-test; P<0.05) with respect to the peak isotonic power of the muscle contractile apparatus (dotted line) in trials with a simulated anatomical catch mechanism.
