Key result
Stretch-tension during rigor significantly reduced individual muscle fiber extensibility (P<0.001) and average muscle fiber diameter (P<0.001) in bovine longissimus dorsi muscles.

May guide bovine meat processing; leaves open confirmation of tenderness benefits beyond animal models.
Does stretch-tension during rigor alter the physical characteristics and tenderness of bovine muscle?
p-value: p=<0.001
Stretch-tension during rigor alters the physical characteristics of bovine muscle, generally increasing tenderness.
BUCK et al. (1967) studied Bovine muscle rigor. Stretch-tension during rigor vs. Different degree of stretch-tension was evaluated on Individual muscle fiber extensibility (p=<0.001). Stretch-tension during rigor significantly reduced individual muscle fiber extensibility (P<0.001) and average muscle fiber diameter (P<0.001) in bovine longissimus dorsi muscles.
