FIGURE 2.

Effects of age and sex on the recovery of injured muscle function. (a–c) Tibialis anterior muscles of 3‐ and 14‐month (mon)‐old male (M) and female (F) mice were injured with BaCl₂ injection and analyzed 14 days after injury. Muscle weight (MW) (a), maximal isometric twitch force (Pt) (b), and maximal isometric tetanic force (Po) (c) were expressed as a percentage of uninjured contralateral control (CTL) (n = 5–9). Data are presented as mean ± SEM. Statistical significance was determined by two‐way ANOVA.
