Did you know?
WebJun 30, 1979 · It is concluded that both the duration of the active state and the rate factors of activation contribute to the determining of the large variation in peak twitch tension at about 2.15 micron, whereas the length-dependent increase in twitch/tetanus ratio appears to be mainly determined by prolongation of the active state duration. Publication types WebThe tension in the muscle is equal to the load during the shortening and the lengthening of …
WebMar 15, 2024 · Students will investigate how nerve stimulation controls muscle … WebIn contrast to the low temperature dependence of force generation, rates of development of tension (time to peak twitch tension and tetanic rise time) and maximal velocity of shortening and power output are markedly temperature depend- ent, with average temperature coefficient (QlO) values of 2.0-2.5.
WebSummation of the twitch tension was observed on repetitive stimulation, with 1 msec, pulses, for 5–7·5 sec. The relationship between tension development and the membrane potential was investigated. The membrane potential was varied by changing the external potassium concentration, [K] 0. WebFast-Twitch fibers obtain their contraction energy mainly from glycogen, without the influence of oxygen. This process is therefore also referred to as anaerobic metabolism. Intermediary type You can imagine the intermediary type of muscle fiber as a kind of hybrid of the other two fibers.

WebIt is further suggested that the development of twitch tension is not due to direct Ca entry but is due to the release of Ca from a local store within or between the cells. The inotropic action of adrenaline is explained in terms of this store.
