Figure 3. Increased femoral cortical bone mass in male mice having completed high intensity sprint interval training was paralleled by reduced mechanical strength.

Bars show the means and SEM for the ultimate strength required to break the right femora and for the bending stiffness (left panels) and serum PINP and RANKL concentrations (right panels). 10° up, even and 10° down indicate the inclination of the treadmill. P-values give the results of One-Way ANOVA. P-values < 0.05 are considered significant.
