The breaking energy of the femurs. The breaking energy of the femoral diaphysis was determined by a three-point bending test. The rat groups were the control (Con) with ovariectomy (OVX) plus vitamin D3 and nicotine (VDN) and no exercise; climbing (Clim) resistance exercise group with OVX plus VDN; and the forced swimming (Swim) exercise group (1 h/day, 6 times/week). The VDN was administered a week after OVX. The exercises started a week after VDN administration. The exercise period was 8 weeks. * p < 0.05 vs. the Con. Values are expressed as the mean ± SE.
