The Mechanochemistry of Muscular Contraction
The dependence of PC a and ATP 1 dephosphorylation on the number of isometric twitches in the iodoacetate-nitrogen-poisoned muscle has been examined. There is no net dephosphorylation of adenosinetriphosphate. PC dephosphorylation varies linearly with the number of twitches and produces equivalent amounts of C a and p~.l Iodoacetate concentrations which block the enzyme, creatine phosphokinase,...

متن کاملThe Effect of Three Types of Military Boots’ Mileage on Knee Muscular Co-Contraction During Running
Purpose: Military boots’ mileage is a main factor that can be influence the risk of sustaining injuries during running. The aim of the present study was to evaluate the effect of three types of military boots’ mileage on knee muscular co-contraction during running. Methods: Fifteen healthy males received three new pairs of military boots. They were asked to wear these shoes for over 6 months. ...
متن کاملKinetics of Muscular Contraction-I **
The kinetics of muscular contraction is basic for the quantitative description of muscle and understanding its molecular mechanism. However, the subject has been embarrassed by several historical accidents. First, due to the lack until recently of adequate high (mechanical) impedance transducers, attention was focussed on isotonic measurement; this led to the idea of muscle as a shortening gene...
متن کاملA Kinetic Model of the Muscular Contraction
In this article, we build a self consistent mean field deterministic model for the muscular contraction. The two main variables are the number of free myosin heads and the number of myosin heads attached to the actin, just after attachment. The model is natural in the sense that it respects the physico-chemical natural constraints. We calculate the stationary state, prove that it is stable and ...
