The 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 کاملMechanical Power Output from Striated Muscle during Cyclic Contraction
1. The mechanical power output of a synchronous insect muscle was determined by measuring tension as the muscle was subjected to sinusoidal length change and stimuli which occurred at selected phases of the length cycle. The area of the loop formed by plotting muscle tension against length over a full cycle is the work done on that cycle; the work done times the cycle frequency is the mechanica...
متن کاملThe Mechanochemistry of Muscular Contraction
The dependence of PC(1) 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(1) and P(1i).(1) Iodoacetate concentrations which block the enzyme, creatine phosph...
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...
