to specifically use lean body mass to estimate RMR ( Cunningham, 1980 ). Whether or not the use of lean body mass and fat-free mass interchangeably may impact the result of predicted RMR and RMR ratio is unknown. Most recently, dual-energy X-ray absorptiometry (DXA) modeling, based on tissue

purpose of this study was to develop a predict equation to calculate body fat percentage in youth soccer athletes from skinfold measurements, considering dual energy X-ray absorptiometry (DXA) values as a reference. Eighty-one males aged 15 to 26 years old (18±2 years; 73.0±8.2 kg; 1.80±1.7 m) from four

by a newly developed sport-specific questionnaire and clinical interview (SEAQ-I), received dual energy X-ray absorptiometry (DXA) bone mineral density (BMD) and body composition scans and blood tests for endocrine markers. Low EA as assessed using the SEAQ-I, was observed in 28% of cyclists. Low

medications. Dual energy x-ray absorptiometry scan showed low bone density with L1-4 Z-score -1.8. Serum calcium and Vitamin D were within normal limits. She was treated for her fractures and returned to activity. Discussion regarding her endocrine management plan was put on hold when she left for a 6 month

, however, peak V ˙ O 2 should at least be scaled to FFM. It has been reported that peak V ˙ O 2 is more strongly correlated with FFM, estimated using dual-energy X-ray absorptiometry, than with body mass ( 21 ) and that the peak V ˙ O 2 of overweight youth is similar to that of lean youth when

SSG or CST was performed 3×40 min/week over 10 months. Whole-body dual-energy X-ray absorptiometry (DXA) scans were used to determine areal bone mineral density (aBMD), bone mineral content (BMC) and lean body mass (LBM). Flamingo balance, standing long jump and 20-m sprint tests were used to
