摘要：The aim of the research was to evaluate the sarcomere length variation in Psoas major muscle in pork and wild boar tenderloin. Microscopic slides were prepared and muscles were evaluated in Nomarski contrast – there were made measurements with the number of 150. Subsequently, sarcomeres length of three different, representative myofibrils were measured for each kind of meat. Values of sarcomere’s lengths of myofibrils were characterized by a normal distribution. The mean length of sarcomere was 3.28 ± 0.23 µm for pork meat and 2.51 ± 0.14 µm for wild boar meat – difference between animals was statistically significant (p = 0.0000). It was stated that sarcomere length for pork meat was dependent on the myofibril. A lower variation in the sarcomere’s length of wild boar meat in comparison with pork meat has been shown. This difference is reflected in tougher wild boar meat texture.
