The optimum proteolytic activity of calpains
was observed in the fresh meat of red deer - 0.085 um/h for one gram of protein (Fig.

Conclusively, an uncontrolled activation of calpain
has been found to be implicated in the pathophysiology of several cardiovascular disorders  including myocardial IRI , and the inhibition of calpains
has been shown to attenuate myocardial stunning and reduce infarct size after ischemia reperfusion  (Figure 1).

The non-significant improvement in texture in the BF muscle may be related to the low calpain
values (Koohmaraie, Seideman, Schollmeyer, Dutson & Babiker, 1988), as well as the high collagen level (Hildrum et al., 2009).
