“…These statistically similar results align to the one found by Malina et al [10] Romann&Fuchslocher [11] and Sherar et al [12] which advocates how much the concentration of the athletes in a determined category of maturation(late, on timeand early) is an important aspect to practical application by coaches in the processes of drafting and development inside the sports category.…”

Backgroud: Football clubs select young people to begin their training as athletes. At this stage of life (childhood and adolescence) occurs the biological maturational process that can cause influences on the soccer performance of young athletes. In addition to this fact, a specificity of each position within the field is related as anthropometric and physiological characteristics of each individual, where goalkeepers are rarely included. Objectives:The goal of this study was to analyze the relation between the skeletal maturation and the chronological age, besides to find out the power of vertical jump in goalkeepers in different youth age divisions in an elite soccer organization. Methods: 31 young goalkeepers made Counter Movement Jump free arms and were evaluated through the App MY JUMP to generate data about vertical jumping. Bone maturation was estimated through the result obtained in a hand and fist teleradiography exam using the Greulich and Pyle protocol and the predicted height was estimated through the Bone Expert protocol.

“…The inter-rater reliability to assess bone age from DXA hand scans was rated as "excellent" between an expert and a newly trained researcher, as shown by an ICC of 0.996 for BMS and 0.994 for bone age. The reproducibility between researchers to estimate bone age was slightly higher than in other studies which had ICCs of 0.99 (Heppe et al 2012) and 0.93 and 0.95 at two different time points (Romann and Fuchslocher 2016). Intra-rater reliability was similarly excellent, above 0.97, and comparable to that of experienced raters with an ICC !…”

“…Intraand inter-observer reliability of DXA derived skeletal age with a mean difference of 0.11 years between x-ray and DXA assessments (95% limit of agreement between À0.85 and 1.05) were found by Heppe et al (2012). Inter-and intra-rater reliability was high between two trained observers (Romann and Fuchslocher 2016) when using the Tanner-Whitehouse 3 (TW3) reference technique to determine skeletal age from DXA scans in young soccer players (mean ± SD: 14.0 ± 0.3 years), with strong correlation between x-ray and DXA derived measurements.…”

Dual-energy x-ray absorptiometry (DXA) scans are frequently used in human biological research to study bone health and body composition. Hand-wrist scans for the assessment of skeletal maturity can also be easily obtained in immature research participants who are being scanned to assess bone health. Whilst assessment by an expert is the desired arrangement such expertise may not be available, and thus knowledge of the relative reproducibility of a trained novice and an acknowledged expert is pertinent. Here we compare the relative reproducibility of an expert and a trained novice on 41 DXA left-hand scans of adolescent males using the Tanner-Whitehouse 3 (TW3) RUS method. The trained novice showed almost perfect reproducibility when evaluating bone age from DXA hand scans compared to an expert in skeletal maturity assessment. Both observers demonstrated reproducibility good enough to suggest that the TW3 method is appropriate to use with DXA hand scans by a trained researcher.

“…Recent studies have also been validating ultrasound and dual-energy X-ray absorptiometry (DEXA) to estimate skeletal age. These alternatives expose the subject to lower and non-ionizing radiation compared to X-ray radiography 39,40 ; however, those alternatives require sophisticated equipment at a high cost, which render its use less attractive in epidemiological studies.…”

Skeletal age (SA) is considered the gold standard to assess the degree of maturation and has been widely used in sports, education and public health areas; however, it requires sophisticated equipment and well-trained technicians. Therefore, it is important to develop non-invasive methods for its evaluation. The aim was to develop an equation to predict SA using the percentage of adult height. SA was measured by Tanner-Whitehouse-3 method, and the percentage of adult height was estimated by two methodologies: Tanner-Whitehouse-3 method (P-TW3) and Khamis-Roche method (P-KR) using 839 schoolchildren of both sexes. Linear regression was used for predicting SA from P-TW3; then P-TW3 was replaced in the equation for P-KR value. Bland–Altman graphs, interclass correlation coefficient and Kappa index were used as validation tests. Model showed a SA predictive capacity of 93.2% in boys and 96.8% in girls. The average differences between SA measured and SA predicted by P-TW3 was 0.0504 (± 0.664) in boys and 0.0144 (± 0.435) in girls (P = 0.229 and 0.667, respectively). When P-TW3 was replaced for P-KR value in the equation, the average differences were − 0.0532 in boys and 0.0850 in girls (P = 0.509 and 0.167 respectively). The present model, based on the percentage of adult height, showed an adequate estimation of SA in children and adolescents and it can be used in the absence of bone X-ray equipment, in healthy boys aged 9 to 15 and girls 8 to 13.
