BLUF: On average, Curtin found that the muscles converted 63 percent of their energy into work—i.e., physical movement. For comparison, the equivalent figures are 42 percent for cows, 34 percent for mice, and 27 percent for rabbits. Greter muscle efficiencies are likely out there, but the breadth of research data is still narrow. I would be interested in Dolphin and Blue Fin Tuna muscle efficiency. Probably research of interest to, say, Boston Dynamics?
