Activation heat in various cross-striated muscles of Rana esculenta: microcalorimetric measurements.


Activation heat (AH) is an important component in energy balance of muscle contraction. It represents energy dissipation of biochemical processes enabling muscle in rest to perform contraction. According to our measurements on intact muscles, AH is 20% of initial heat production in twitch, and 10% in tetanus. Significantly different AH values have been obtained for muscles of parallel and not parallel fibre architecture.
