“…The WHO classification system was used to categorise BMI. 21 A whole body DXA scan was performed on the Stratos dR (DMS Group, France) 22 according to the manufacturer's guidelines for the assessment of body composition. Trunk peripheral fat ratio (TPFR), calculated as the trunk fat mass (FM) divided by the sum of the FM of the arms and legs, was used to determine the distribution of body fat throughout the body.…”

“…Bone mineral density (BMD; g • cm − 2 ) was determined for the whole body, lumbar spine (L1-L4) and proximal femur in all participants by DXA using the Stratos dR scanner (DMS Group, France). The percentage root-mean-square coefficient of variation for this scanner has been reported as 1.22 % and 0.86 % for the lumbar spine and total hip respectively [25]. All scans were performed in accordance with manufacturer instructions.…”

Musculoskeletal Health, Kidney and Liver Function in Retired Jockeys

The long-term implications of making-weight daily on musculoskeletal health and functioning of the kidney and liver remain unknown. This study aimed to investigate musculoskeletal health and kidney and liver function in a group of retired jockeys. 28 retired male jockeys (age 50-70 years) provided fasting blood samples for markers of bone metabolism and kidney and liver function. A dual-energy x-ray absorptiometry (DXA) scan was performed for the assessment of bone mineral density (BMD). Established reference ranges were used for interpretation of results. Comparisons were made between retired jockeys based on the professional racing licence held: Flat, National Hunt or Dual. Mean whole-body osteopenia was reported, with no differences between groups. Bone markers, micronutrients, electrolytes and associated hormones, and markers for kidney and liver function were within clinical normative ranges. No differences existed between groups. Results indicate the retired jockeys in this study do not demonstrate compromised bone health or kidney and liver function. However, the retired jockeys may not have undergone chronic weight cycling in the extreme manner evident in present-day jockeys, indicating the next generation of jockeys may face more of a problem. Jockeys should be tracked longitudinally throughout their racing career and beyond.

Dual-energy X-ray absorptiometry is recognized as the ‘gold standard’ for the diagnosis of osteoporosis. This method is used not only for the initial assessment of the state of the IPC, but also for further monitoring of treatment or preventive measures. It allows you to compare the data of a patient with successive measurements during a long observation. However, it is impossible to evaluate the results of studies in dynamics on devices of different manufacturers without standardizing indicators or introducing correction factors. A simple method for recalculating the T-score obtained on a Dexxum 3 apparatus (OsteoSys, South Korea) is presented in order to compare it with a similar indicator of a bone densitometer Lunar Prodigy (GE Healthcare, USA).
