A robust neuromuscular system protects rat and human skeletal muscle from sarcopenia


Figure 2. Gait analysis reveals impaired hindlimb function with age. Gait parameters were analyzed using a catwalk device in 8-10 months old (adult) and 18-20 months old (early sarcopenic) rats. (A) Gait speed and stride length (B) Time rats keep their front or hind paws in contact with the surface (stand time), or not in contact with the surface (swing time). (C) Representative paw prints from adult and early sarcopenic rats. LH: left hind, RH: right hind, LF: left front, RF: right front. For all graphs n=9-15 per group. * p<0.05 ** p<0.01 *** p<0.001 with a one-way ANOVA test.
