Yeah, but should probably point out the relative time scales involved. In muscle, once the nerve impulse is off, in a non-pathological state, muscle tension in the motor unit will drop to zero within hundreds of ms. For example http://www.bem.fi/book/21/fi/2108.gif http://www.bem.fi/book/21/fi/2108.gif shows a typical force-time curve for an impulse. I have no idea what the equivalent would look like in this case, but I imagine in a purely passive cooling solution, it'd have quite a long time constant. I don't have the paper, and in the abstract they awkwardly compare the strength to human muscle length and weight, when typically, its muscle cross section that bounds a particular muscles strength. This is important because if you start stacking these fibers in parallel to get more strength, then you pretty much dictate some sort of active cooling system to maintain any type of performance and control.
