text: The rate of cardiac contraction is determined by attachment and detachment rate of cross bridges, i.e., by myosin ATPase activity and by the rate of activation induced by Ca2+ ions and their removal (Hoh et al., 1988), and evidence is accumulating that both Ca2+ management and cardiac myosins are modulated by seasonal acclimatization in crucian carp.
