Subcellular events associated with the development and release of isometric tension in post-mortem bovine, rabbit and porcine skeletal muscle

Post-mortem physiochemical changes in turkey muscle

“…The rate up for red muscle was always greater than that of white muscle. This result is consistent with the findings ofSexton and Gersten (1967) andBusch (1969). It should also be noted that the rate difference between the two muscle types averaged only about one or two units and only at 2°C was it greater.…”

“…The simultaneous measurement of extensibility and isometric tension is allowed with the use of a combined rigorometer and physiograph(Schmidt et al, 1968a(Schmidt et al, , 1968b. More recently the subcellular events associated with the development and release of isometric tension in post-mortem rabbit and porcine striated muscle was studied byBusch (1969). Busch demonstrated that the isometric tension development closely parallels the post-mortem changes in length and that the loss in extensibility does not occur until maximum isometric tension has been reached.…”
