Summary

ELECTRICALLY STIMULATED OVINE MUSCLES, RESTRAINED FROM SHORTENING DURING RAPID CHILLING AT 273-274 OR 288-289 K (0-1 OR 15-16 DEG C), HAD LOWER SHEAR FORCE VALUES AFTER 1 AND 2 DAYS AGING AT 273-274 K THAN UNSTIMULATED CONTROLS, BUT WERE NOT SIGNIFICANTLY DIFFERENT AFTER 4 DAYS AGING OR MORE. DIRECT MEASUREMENT OF MUSCLE FIBER LENGTH SHOWED THAT CONTRACTION VALUES OBTAINED FOR MUSCLES ASSIGNED TO GO INTO RIGOR AT 273, 288, 303 OR 313 K (0, 15, 30 OR 40 DEG C) WERE SIGNIFICANTLY LESS FOR STIMULATED MUSCLES THAN FOR CONTROL MUSCLES AT 273 K. AT TEMPERATURES HIGHER THAN 288 K, INCREASE IN TENDERNESS DUE TO STIMULATION BECAME SMALL AFTER 7 DAYS AGING AT 273-274 K, WHEREAS AT 273 K AGING FURTHER INCREASED IMPROVEMENT DUE TO STIMULATION.
