The high thermodynamic efficiency of the process, above all, is difficult to explain on the basis of present theories. A model of the elementary effect in muscle contraction is proposed which aims at high thermodynamic efficiency based on an approximate equilibrium between chemical and mechanical ...
contraction,muscular contraction shortening- act of decreasing in length; "the dress needs shortening" contracture- an abnormal and usually permanent contraction of a muscle tetanus- a sustained muscular contraction resulting from a rapid series of nerve impulses ...
Although muscle contraction is one of the principal themes of biological research, the exact mechanism whereby the chemical free energy of ATP hydrolysis is converted into mechanical work remains elusive. The high thermodynamic efficiency of the process, above all, is difficult to explain on the basi...

If applied to muscle it could give us a deeper insight into the nature of contraction : but before it can be applied, one of the most basic questions of biology has to be answered : Are complex biological phenomena, such as contraction in muscle, made up of equilibrium reactions ?. 1951...
