Extended Data Table 5 Values of maximum enthalpy efficiency for locomotor muscles from different species

From: Remarkable muscles, remarkable locomotion in desert-dwelling wildebeest

  1. Measurements were all made on intact fibre bundles. Design C, cyclic movement at the listed frequency and with intermittent stimulation. Design I, isotonic (that is, force-clamped) or isovelocity (that is, velocity-clamped) conditions following a period under isometric (that is, constant length) conditions. In design I, stimulation was continuous, and efficiency was measured only during shortening. Data are from previous studies11,17,31,35,36,37.
  2. *Antigravity muscle.
