Dual energy x-ray absorptiometry (DXA) is widely considered the gold standard body composition measurement technique, but DXA BF% values measure consistently higher than other techniques. Therefore, the main purpose of this study is to determine the lowest DXA-estimated whole-body fat mass in free-living athletes with unrestricted access to food. In this cross-sectional analyses, 732 participants across 18 competitive sports (643 athletes; 88 %) plus two (male and female) \"non-athlete\" male and female cohorts (89 non-athletes; 12 %) underwent a whole-body DXA scan using a Horizon A Hologic™ device (software version 13.6.0.5; TBAR 1209), performed and analyzed by a single operator. The average BF % in 454 males (20.9 ± 3.8 years) was 18.2 ± 4.9 % (range 10.3 - 37.2 %), with basketball players having the lowest BF% (15.3 ± 2.6 %) and non-athletes having the highest BF% (21.6 ± 5.4 %) (1-way ANOVA between 10 teams: F = 12.3; p < 0.0001). The average BF% in 278 females (21.3 ± 5.5 years) was 27.1 ± 5.1 % (range 16.2 - 45.3 %), with runners having the lowest BF% (23.5 ± 3.5 %) and non-athletes having the highest BF% (31.7 ± 6.3 %) (1-way ANOVA between 10 teams F = 12.9; p < 0.0001). In absolute values (kg), the average body fat for males was 19.9 ± 8.0 kg (range 6.7 - 62.0 kg) and 18.9 ± 6.4 kg (range 9.2 - 49.7 kg) for females. These data suggest that the lower limits of whole-body fat mass in free-living competitive athletes is approximately 10 % for males and 16 % for females.

The participants were assigned to 3 different groups: control group (CG; n = 15), contrast training group (CTG; n = 13) and hypertrophy training group (HTG; n = 13). The duration of the training protocol was six months. The experimental groups performed two sessions of strength training per week; the duration of each session was forty-five minutes. Several measurements (which included anthropometrics, body composition, bone parameters, maximal strength parameters, physical performance parameters, fracture risk and quality of life) were performed in the three groups before and after the six-month training period. The different measurements of the protocol were carried out under the same conditions with identical materials and investigators for all the participants and for each approach. The current study has demonstrated that the two training modalities show common benefits such as improving maximal strength, physical performance and quality of life parameters but have no significant effects on bone mineral density (BMD) and bone mineral content (BMC). The influence of training was marked more for improving maximal strength and reducing fracture risk for the contrast training group (who performs movements at high speed) compared to the hypertrophy training group (who performs movements at spontaneous speed). In conclusion, this study shows that both resistance training programs are effective in improving maximal strength, physical performance and quality of life in older adults with low SMI.

Topics included an update on clinical uses of osteoanabolic agents, management of patients discontinuing denosumab, bone health optimization for orthopedic surgery, estrogen and testosterone in the management of osteoporosis, osteoporosis treatment in the very old, overview of rare bone diseases, treat-to-target for osteoporosis, and a progress report on global activities of Bone Health ECHO.

Endocrinology fellows, selected from attendees of the Santa Fe Fellows Workshop on Metabolic Bone Diseases, held the two days preceding the SFBS, participated with presentations of oral abstracts.
