Exercise affects muscle metabolism and composition in the untrained muscles. The proteome of muscle tissue will be
affected by exercise and resting. This is of economic importance for pork quality where transportation relates to exercise of untrained
muscles. Rest reverses exercise effects. The objective of this research was to develop potential protein biomarkers that predict the
optimal resting time after exercise related to optimal pork quality. Ten litters of four female pigs were within litter allocated to the four
treatment groups: exercise by running on a treadmill for 27 minutes followed by rest for 0, 1, or 3 h; control pigs without exercise.
Proteome profiles and biochemical traits measuring energy metabolism and meat quality traits expected to be related to exercise were
determined in the Longissimus and the Biceps femoris of the pigs. The results indicated associations between protein abundances in
muscles and exercise, resting, and biochemical traits.
