The time-course analysis of 20-week contest preparation with accompanying mean average (mean ± SEM; 95% CI) comparison between the BC and MBC on a) bone mineral content (BMC), and b) bone mineral density (BMD). The BC showed to have a slightly higher mean BMC (2.24 ± .003; 95% CI: 2.23–2.25 kg) compared to the MBC (2.10 ± .009; 95% CI: 2.07–2.12 kg). The BC and MBC showed to have similar mean BMD measures (1.11 ± .007; 95% CI: 1.09–1.13 g⋅cm^− 2 vs 1.11 ± .006; 95% CI: 1.09–1.13 g⋅cm^− 2). The dashed red line denotes the competition
