Maximum active tension ca
WebMuscle contraction is the activation of tension -generating sites within muscle cells. [1] [2] In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as when holding something heavy in the same position. [1] WebEach muscle was allowed to equilibrate under control conditions (2.25 mM2+ Ca, stimulus frequency 20 min"') for 3-4 hours during which its length gradually was in- creased to …
