Initial changes in gene expression following 1-week of exercise are attenuated in adult mice.

The fold change in mRNA expression within cortical bone was measured after 5-days of exercise and expressed relative to 13-week sedentary controls. Significant main factor effects are noted for age (A*), exercise (E*), and their interaction (ExA*). Tukey post hoc analysis between sedentary and exercise with a p-value < 0.05 are noted by ‘*’. Mean ± std. (n = 6).
