“…Some degree of error is implicit in SA estimates and the error impacts the distribution of youth by skeletal maturity status. Nevertheless, the classification criteria used in the present study were consistent with other studies of the general population of youth [28] and of athletes [2,29,30], although a narrower band (SA-CA difference of ± 3 months) defining early and late maturity status has been used [31]. The latter band, however, is within the range of standard errors of SA assessments.…”

“…Biological maturation is a process marking progress toward the biologically mature or adult state. Although assessments of skeletal age (SA) based on the bones of the hand and wrist are generally used in a clinical context, SA is also a commonly used indicator of maturity status in studies of youth athletes [ 1 , 2 ]. An assigned SA is the chronological age (CA) at which specific stages of maturity of the hand-wrist bones are attained relative to the reference sample upon which the method of assessment was developed.…”

Background Skeletal age (SA) is an estimate of biological maturity status that is commonly used in sport-related medical examinations. This study considered intra-observer reproducibility and inter-observer agreement of SA assessments among male tennis players. Methods SA was assessed with the Fels method in 97 male tennis players with chronological ages (CA) spanning 8.7–16.8 years. Radiographs were evaluated by two independent trained observers. Based on the difference between SA and CA, players were classified as late, average or early maturing; if a player was skeletally mature, he was noted as such as an SA is not assigned. Results The magnitude of intra-individual differences between repeated SA assessments were d = 0.008 year (observer A) and d = 0.001 year (observer B); the respective coefficients of variation were 1.11% and 1.75%. Inter-observer mean differences were negligible (t = 1.252, p = 0.210) and the intra-class correlation coefficient was nearly perfect (ICC = 0.995). Concordance of classifications of players by maturity status between observers was 90%. Conclusion Fels SA assessments were highly reproducible and showed an acceptable level of inter-observer agreement between trained examiners. Classifications of players by skeletal maturity status based on assessments of the two observers were highly concordant, though not 100%. The results highlight the importance of experienced observers in skeletal maturity assessments.

“…It is also important to remember that the morpho-functional characteristics of young athletes are influenced by growth and maturity [ 11 , 27 ], and this fact can offer advantages or disadvantages during competition. The calculated biological age for body height was 91.8% ( n = 45) in boys and 79.9% ( n = 30) in girls in accordance with current physical development standards for Polish children and adolescents [ 20 ].…”

“…Little attention has been directed to the relation between anthropometric measures and special motor fitness [ 8 , 9 , 10 ]. Several authors have studied the relationship between various anthropological variables and body composition for success in table tennis [ 11 , 12 , 13 ]. However, some research states that, between the ages of 10 and 14 years, no distinct anthropometric player profile exists [ 6 ].…”

In the present study, we aimed to identify the impact of chosen anthropometric measurements on the special physical fitness of elite junior table tennis players at different stages of sport training. A total of 87 table tennis players aged 13.4 ± 1.74 years (43.7% girls and 56.3% boys) from two Polish teams were analyzed. The anthropometry measurements included height, sitting height, body weight, arm span, humerus and femur breadths, five skinfold thicknesses, and five girths were assessed. Participants’ somatotypes were also calculated using the Heath–Carter method as well as body mass index (BMI), which was constructed using the lambda, mu, sigma (LMS) method. Body composition via a bioelectric impedance analysis was also analyzed. The level of special fitness of athletes was determined using tests from the Table Tennis Specific Battery Test, assessing reaction and displacement speeds. Mesomorphic (4.1) and ectomorphic (3.8) profiles were registered for boys and girls, respectively. Boys achieved higher scores than girls for almost all variables, with the exception of ectomorphic somatotype (p = 0.274), skinfold triceps (p = 0.444), and calf skinfold medial (p = 0.609). The relationship between the body height, thickness of the skinfolds of the triceps and suprailiac, biceps, and waist circumference and arm span in all three motor tests was observed, simultaneously significantly higher results were obtained by competitors at the specialist stage of training. Knowledge of the somatic and motor characteristics of young athletes can help coaches in creating a specific training program for improved health and performance, taking into consideration the athletes’ biological development, potential, and pre-disposition.

“…In a recent study, Coelho-e-Silva et al (2022) examined the physical growth and biological maturation of young competitive table tennis players. Their results showed a substantial variation (between the 10th to 100th percentile) in the height and body mass of players when compared to reference values.…”

The purposes of this study were to determine the growth and maturity status of young competitive tennis players and to examine their associations with national rankings. The participants were 36 male and 34 female players who competed in the U14 national team selection tournament in 2022. They were divided into three groups according to their results and entries as national players (n = 8), main draw players (n = 31), and qualifying players (n = 31). Ages at peak height velocity and growth status were calculated. Regardless of gender, the mean height and body mass percentiles of players were above the 60th centile. In girls, the results indicated that both national and main draw players were significantly more advanced in maturation (p< 0.05) and had higher body mass indexes (p< 0.05) than qualifying players. In boys, no significant differences were observed among the three groups for all variables. Correlation results showed that maturity status was the most correlated (p< 0.01) variable in girls. No significant relationships between rankings and other variables were obtained for boys. These results suggest that physical size and advanced maturity should be taken into consideration in the selection and identification of youth elite female tennis players.
