Figure 5.

Comparisons of some of the locomotor parameters for the wild-type (WT) and myostatin-knockout (KO) mice. The mean and one standard deviation for the walking speeds and peak vertical forces for forelimbs and hind limbs of the two groups of mice are compared. Significance values are indicated in the upper left corner. The designation “n.s.” indicates that the values are not significantly different from each other. Note that the myostatin-deficient (KO) mice walk significantly more slowly but the peak vertical forces are not significantly different from that of the wild-type (WT) mice.
