Figure 1. Leukocyte infiltration in human skeletal muscle after resistance exercise. (A) Representative hematoxylin and eosin staining of a muscle cross-section (leukocytes infiltration indicated by an arrow). (B) Resistance exercise immediately increased leukocyte infiltration into skeletal muscle. High protein supplementation before and after resistance exercise attenuated exercise-induced leukocyte infiltration. * Significant difference against Baseline, P < 0.05; † Significant difference against Low Protein, P < 0.05. Low protein: 14% protein; High protein: 44% protein in weight.
