Back to the story!
The peak power output of each extensor muscle when it stores energy in the cuticle springs is about 36 mW, while the peak power output during the jump itself is about 0.75 W. There is thus a 10-fold power amplification brought about by the use of mechanical springs as intermediate energy stores.
The total energy required for a jump is 10 - 12 mJ. Of this, rather more than half is probably stored in the semi-lunar processes of the two legs. The remainder is stored mainly in the tendon of the extensor muscle, and perhaps some in the cuticle of the femur itself, which is the origin of the extensor muscle.
