Anthropometric measures included body height (Martin metal anthropometer, Switzerland) and body mass (A&D Instruments Ltd., Abingdon, UK). BMI was also calculated (kg.m−2). Whole body and lower body region (WB BMD and lower limbs BMD, g.cm−2), bone mineral density and bone mineral content for the whole body (WB BMC, g) were assessed via dual-energy X-ray absorptiometry (DXA, Hologic Discovery QDR Series, Waltham, MA, USA) [29 (link),30 (link)].

Body height was measured to the nearest 0.1 cm using a Martin metal anthropometer, and body mass was measured to the nearest 0.05 kg with a medical electronic scale (A&D Instruments Ltd., Abingdon, UK). Body mass index (BMI) was also calculated (kg/m2). Pubertal development was assessed by self-report using an illustrated questionnaire according to the Tanner classification method (Tanner 1962) that has been previously validated [29 (link)] and used in our previous studies in boys [27 (link), 30 (link)-31 (link)]. The boys were given photographs, figures and descriptions of genitalia and public hair development stages, and asked to choose the one that most accurately reflected their appearance. If there was a disagreement between the stage of genitalia and pubic hair, then the final decision was made according to the degree of genitalia development [29 (link)].

Anthropometric parameters were measured with precision of 0.1 cm of height (Martin metal anthropometer) and 0.05 kg of body mass (A&D Instruments, Abingdon, UK). For body composition assessment, a DXA scanner (Hologic, Marlborough, MA, USA) was used. Body fat mass (FM) and lean body mass (LBM) were evaluated using a dual-energy X-ray absorptiometry (DXA).

The participants’ body height (Martin metal anthropometer) and body mass (A&D Instruments Ltd., Abingdon, UK) were measured to the nearest 0.1 cm and 0.05 kg, respectively. The calculation of the body mass index (BMI) was completed as a ratio of body mass to the height squared (kg/m2). The dual-energy X-ray absorptiometry (DXA) using the DPX-IQ densitometer (Lunar Corporation, Madison, WI, USA) equipped with proprietary software, version 3.6 was used to measure the body composition of the participants. All participants were scanned in light clothing. They were laid flat on their backs, arms on their sides and were motionless. Total body (TB) fat mass (FM; kg) and lean body mass (LBM; kg) were measured and the TB FM% was calculated. The same examiner conducted the DXA measurements and evaluated the results. The coefficients of variations (CVs) for the obtained results were less than 2%.

Height (Martin Metal Anthropometer) and body mass (A&D Instruments Ltd., Oxfordshire, UK) of the participants were measured to the nearest 0.1 cm and 0.05 kg, respectively. Body composition was assessed via dual-energy X-ray absorptiometry. Scans of the whole body were performed on each of the subjects using Lunar DPX-IQ Densitometer (Lunar Corporation, Madison, WI, USA) and analyzed for fat mass and fat-free mass. The coefficient of variations (CVs) for body composition measurements were less than 2% (16) .
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
