Chronological age is used as a basis for determining and comparing the motor skill levels of football players. However, it is known that there are early maturing and late maturing players in the same age group. The aim of this study is to compare the motor skill levels of football players in the same age group by bio-banding and to investigate the importance of bio-banding on motor skill levels. 81 male football players between the ages of 12-15 participated in the study voluntarily. Gross motor skills of the football players participating in the study were determined with Deutscher Motoric Test (DMT 6-18), which consists of 8 tests, namely, (DMT20m sprint, DMTside jump, DMTflexibility, DMT standing long jump, DMT sit-up, DMTbalance, DMT push-up, DMT6 min running). Bio-banding was used to determine the maturity level of football players. As a result of the study, it was determined that there are football players with different maturity levels in the same chronological age grouping. There was no difference in the comparison of sprint, side jump, flexibility, push-up variables between groups according to bio-banding. There was a significant difference in the comparison of balance, sit-up, standing jump and running variables between groups according to bio-banding. It was determined that it was in favor of prepubertal in the sit-up variable, and in favor of pubertal in the balance and sit-up, running and standing jump variables. As a result, it has been determined that there are football players with different maturation levels in the same age group in the bio-bandinged football players, and this situation affects the motor skill levels. It is recommended to use bio-grouping in addition to chronological age when determining the motor skill levels of athletes in all team sports, especially football players. ​Extended English summary is in the end of Full Text PDF (TURKISH) file.   Özet   Kronolojik yaş futbolcuların motor beceri düzeylerinin belirlenmesinde ve karşılaştırılmasında temel olarak kullanılmaktadır. Fakat aynı yaş grubu içerisinde erken olgunlaşan ve geç olgunlaşan futbolcuların olduğu bilinmektedir. Bu çalışmanın amacı aynı yaş grubu içerisinde yer alan futbolculara biyo-gruplama yapılarak motor beceri düzeylerinin karşılaştırılması ve biyo-gruplamanın motor beceri düzeyleri üzerine öneminin araştırılmasıdır. Çalışmaya 12-15 yaş arası 81 erkek futbolcu gönüllü olarak katılmıştır. Çalışmaya katılan futbolcuların kaba motor becerileri 8 testten oluşan Deutscher Motorik Test (DMT 6-18) (DMT20m sprint, DMTyana sıçrama, DMTesneklik, DMTdurarak uzun atlama, DMTmekik, DMTdenge, DMTşınav, DMT6 dk koşu) ile belirlenirken, futbolcuların olgunluk düzeylerinin belirlenmesinde Biyo-gruplama kullanılmıştır. Çalışma sonucunda aynı kronolojik yaş gruplamasında farklı olgunluk seviyelerine sahip futbolcuların olduğu tespit edilmiştir. Sprint, yana atlama, esneklik, şınav değişkenlerinin biyo-gruplamaya göre gruplar arası karşılaştırılmasında fark saptanmamıştır. Denge, mekik, durarak atlama ve koşu değişkenlerinin biyo-gruplamaya göre gruplar arası karşılaştırılmasında anlamlı fark olduğu, mekik değişkeninde pubertal öncesi lehine, denge ve mekik, koşu ve durarak atlama değişkenlerinde pubertal lehine olduğu tespit edilmiştir. Sonuç olarak, biyo-gruplama yapılan futbolcularda aynı yaş grubu içerisinde farklı olgunlaşma seviyesine sahip futbolcuların olduğu, bu durumun motor beceri düzeylerini etkilediği tespit edilmiştir. Başta futbolcular olmak üzere bütün takım sporlarında sporcuların motor beceri düzeyleri tespit edilirken kronolojik yaşa ek olarak biyo-gruplamanın da kullanılması önerilmektedir.

Abstract BackgroundMany treatment decisions in children’s Orthopaedics are based on age. This study determined whether a discrepancy between chronological age (CA) and skeletal age (SA) is dependent on BMI and if overweight or obese children would have an advanced SA.Materials and Methods120 children between ages 8-17 with an adequate hand radiograph and a correlating BMI were enrolled by retrospective chart review. Stratification based on age, sex, ethnicity, and BMI percentile was performed. For each age group, 6 males and 6 females were selected with 50% of each group having an elevated BMI. Two blinded physicians independently evaluated hand radiographs and recorded the SA. Statistical analyses evaluated inter-rater reliability and any discrepancy between groups.ResultsThe final statistical analysis included 96 children. The Intraclass Correlation Coefficient for SA determined by the two reviewers was excellent at 0.95. A difference of 13 months was found between CA and SA in the elevated BMI cohort versus the non-elevated BMI cohort, (p<0.001). No significant difference was seen between CA and SA for the non-elevated cohort (p=0.72), while matching for age and sex. ConclusionChronological age and skeletal age are not always equivalent especially in pediatric patients who are overweight or obese.

Purpose:  to evaluate the chronological and dental age of children in Lviv and the Lviv region aged 10-13 years with the help of the modified formula Cameriere.  Methods. Оrthopantomograms  46 children (26 boys and 20 girls) aged 10-13 years from Lviv and Lviv region have been used for this study. A questionnaire was developed for the submission of individual patient data and a standardized format for making their indicators derived from orthopantomograms (OPG). The examination of the area of the lower seven teeth on the left was done using the Cameriere method and the age of the child was evaluated, which was further compared with the chronological age.  Results.The obtained results of the study showed a high accuracy and reliability of the estimation of dental age in children up to 10-13 years with the help of the Cameriere formula modified by us. The research is based on the detection of physiological changes (the rate of formation of the roots) in the permanent teeth of children using the X-ray method.  Evaluating the results obtained by two methods, among girls and boys of the selected age group, a statistically significant strong correlation between the chronological age and the age calculated by the Cameriere method was revealed. Cameriere research has been carried out in many countries around the world and, in particular, in European countries, by implementing the general formula. Children in the period of occlusive bite remain the most critical in terms of age and, therefore, the determination of the correct time for dental interventions. In this age group, the development of permanent teeth passes through different stages and depends on many factors of the environment, genetic, geographical and food factors. The process of teething also affects many local factors, such as space and space for a permanent tooth in the dental artery and the loss of temporary precursors. Even with a large number of factors affecting the eruption and formation of permanent teeth in children, this method showed high accuracy and independence. In order to assess the Cameriere method among the children under study and its further practical application, a comparison was made between the age obtained using this methodology and the chronological age of the children under study in different age groups, both among boys and girls. Analyzing the obtained data, it was found that the mean of chronological age among the studied boys aged 10-11 (n = 14) was 11.02 ± 0.59 years, and the Cameriere method was 10.63 ± 1.03 years.  Student's assessment did not reveal a significant difference between the data (p = 0.22) for the age group of 10-11 years.  Further analysis among the studied boys revealed that in the age group 12-13 years the average chronological age was 12.94 ± 0.49 years, and the age was determined by the Cameriere method 12.59 ± 0.63 years, and no significant difference was established between them  (p = 0.14). The results of the studies have shown the suitability of the Cameriere formula modified during the process, based on the assessment of open tops and the number of teeth with completed root formation as a marker for the physiological development of the child and one that can be used to determine the child's age.Since studies had a limited age range on a particular sample of dental patients, further studies should evaluate the utility of this method in a larger sample of children in the extended age range of the given region of Ukraine and, if possible, adjust the formula we modified for the stability of the averaged indicators in different samples by age and sex.

The most important variables for measuring performance in team sports such as football are physical condition and technical and tactical performance. However, because of the complexity of the game of football it is difficult to ascertain the relative importance of each of these variables. The aim of the present study was to develop a standardized test battery to evaluate physical performance in football players. The F-MARC test battery was designed to closely relate to the football player's normal activity and comprised a functional, structured training session of approximately 2.5 hours. It included a “quality rating” of the warm-up procedure, tests of flexibility, football skills, power, speed, and endurance. The players finished with a cool-down. A total of 588 football players underwent the F-MARC test battery. Mean values for performance on each test are presented for groups of differing age and skill levels. The test battery proved to be a feasible instrument to assess both physical performance and football skills. This study supports the proposal by Balsom (1994) that analysis of an individual player's physical profile, in relation to mean values for a similar age group and skill level, might be of assistance to the coach in objectively evaluating the effects of a specific training program. It may also be of use to the physician and physical therapist responsible for monitoring progress during rehabilitation after football injuries.

Abstract In the rugby and soccer sevens, players need special motor capacities, such as aerobic and anaerobic resistance, proper force in the muscles that work during game actions, as well as speed and agility. The purpose of the papers was to assess the motor capacity in the competition period, among female athletes who practice team sports. The study comprised 26 subjects, 12 of whom activate in the female rugby team of CS Politehnica Iasi, and 14 of whom belong to the soccer team of Naviobi Iasi. Both teams are champions in their leagues. We applied the following tests: 250m run, long jump without take-off, throwing the 2kg medicine ball, 30second abdominals, and 5m back and forth run. The data obtained were interpreted in SPSS 20.0 for IBM, by applying the t test for independent samples. Results have shown a significant difference (p<0.05). Significant differences were found only for the test that measured the force of abdominal muscles for which the female rugby players scored significantly higher than the rest. In all the other tests, the mean results were similar or very close. We found that the motor experience within the game influenced the results obtained, just like general physical training; they are both important for supporting the specific effort. The tests we applied mid-competition period.

Purpose: To evaluate the actual variability of the mean difference between chronological and dental age using the Cameriere method of open apices and to test its accuracy in variable age groups. Method: We selected studies that contained data about the mean, standard deviation, and number of cases for chronological age, dental age and gender. We used a random-effects model. Statistical significance was estimated, at a p < 0.05, using prediction intervals. For the analysis of publication bias we used the funnel plot and Egger’s regression test for plot asymmetry. I2 was used to test the presence of heterogeneity between studies. The Z test was used to test for statistical differences between subgroups, with p < 0.05 being considered statistically significant. We also used 95% for confidence intervals and prediction intervals. Results: In boys, the average difference between chronological and dental age was 0.44 (0.26–0.63) years, while in girls the average difference between chronological and dental age was 0.34 (0.19–0.49) years. In the 6–7 years age group and in the 14–15 years age group, there was a statistically significant difference between dental and chronological age. Our study shows that the Cameriere method is useful for estimating the chronological age, with errors of less than one year. Conclusions: The Cameriere method of evaluating dental age using open apices is sufficiently accurate for forensic practice, at least in the 7–14 age-interval.

The aim of this research is to determine whether there are statistically significant differences in the anthropological status of young football players in relation to chronological age within one calendar year. The sample consisted of a total of 50 male respondents, Technical School “Mihajlo Pupin” students from the municipality of Indjija. The sample was divided into two subsamples according to chronological age (born by June 30, 2005; born July 1, 2005 and later). The students are also members of the football club in which they train. By examining the morphological characteristics, data were obtained in the following variables: body height, body mass and body mass index. Static and explosive power testing data were obtained in the following variables: standing long jump, bent arm hang and running 30 meters. It was concluded that there are no statistically significant differences between young football players of different chronological ages in anthropological status. No differences were found in the total space of tested and measured variables (MANOVA) nor in the individual space (ANOVA). The research included two anthropological spaces, morphological and motor, and none of them showed differences between young football players of different chronological ages. Out of a total of six measured and tested variables, the only variable that was on the border of the difference between the groups was running 30 meters, which may indicate that different explosive power of the lower extremities between the two tested groups, in this case, in favor of the younger group.
