This study evaluated the effect of stretching hot-boned sheep hindlegs from 40 sheep carcases, classified as mutton, using a prototype device (SmartStretch™). Left and right legs were collected pre-rigor and randomly allocated to one of four treatments; 0days ageing+SmartStretch™, 0days ageing+no stretch, 5days ageing+SmartStretch™ and 5days ageing+no stretch. There was a significant interaction between stretch treatment and ageing (P<0.05) for shear force of the m. biceps femoris such that stretched and aged samples were the most tender. By contrast stretched m. semimembranosus (SM) had a significantly (P<0.05) lower shear force only at 0days of ageing. Stretching produced longer sarcomeres (P<0.001) for both the SM and m. semitendinosus muscles. Myofibrillar degradation indicated by particle size analysis or histology was not affected by stretching, but there was an ageing effect (P<0.001). SmartStretch™ provided significant improvements in tenderness of the individual muscles.
