Key result
In permeabilized rabbit psoas muscle fibres, the maximum efficiency of contraction was 0.36 at a shortening velocity of 0.27 muscle lengths per second.
In rabbit skeletal muscle fibres, the maximum efficiency of contraction is 0.36 at a shortening velocity of 0.27 muscle lengths per second.

Animal data on skeletal muscle leave cardiac translation open; hypothesis-generating for human muscle energetics.
He et al. (1999) studied this question. Photolytic release of ATP was evaluated on Relationship between mechanical power output and the rate of ATP hydrolysis. In permeabilized rabbit psoas muscle fibres, the maximum efficiency of contraction was 0.36 at a shortening velocity of 0.27 muscle lengths per second.
