Muscle to body weight ratios for ageing mice. Average quadriceps muscle to body weight ratio (n = 8 for each age group). One-way ANOVA indicated significance among the groups (P <0.001). An asterisk indicates a significant difference between the 6-month-old group and every other group except 18 months old (P <0.05); two asterisks indicate a significant difference between the 12-month-old group and every other group (P <0.05).
