Effects of short-term NMES training on muscle integrity, macrophage content, muscle mass, size and function. A Proportion of myofibers positive for IgG in mice submitted either to the control procedure (n = 7) or to NMES (n = 6). B Proportion of myofibers positive for myosin heavy chain embryonic in control (n = 7) and NMES (n = 6) mice. C Proportion of myofibers with central nuclei in control (n = 8) and NMES (n = 9) mice. D Number of CD64pos cells (i.e., macrophages) per mm2 in control (n = 5) and NMES (n = 5) mice. E Gastrocnemius muscle weight of control (n = 10) and NMES (n = 11) mice. F Gastrocnemius myofiber cross-sectional area of control (n = 8) and NMES (n = 9) mice. G Maximal isometric force production longitudinally recorded throughout the study design in control (n = 15; blue circles) and NMES (n = 15; purple squares) mice. Values are reported as mean ± SD
