“…These transformations have repercussions on the body image, perception of efficiency and social adjustment, often leading the puberty to exhibit ambiguous attitudes, ranging from insecurity and isolation to the questioning of the authorities, seeking autonomy and recognition of other youths 28 . Accelerated gains in muscle mass and height at this stage are not accompanied by proportional increases in strength and coordinating abilities, making sports motor performance unstable and irregular 30,31,32 . Allen and Laborde 33 recommend that coaches of this age group be patient, tolerant and able to mediate conflicts through the direct involvement of all involved.…”

This study aimed to investigate the relationship between personality traits and leadership characteristics of handball coaches of school teams in the state of Rio de Janeiro, Brazil. Method: The sample was composed of 31 male individuals (41.71 ± 9.61 years) registered as coaches at the Federation of Student Sports of Rio de Janeiro (FEERJ). The data collection instruments were the Eysenck Personality Questionnaire, the Revised Leadership Scale for Sport and a sociodemographic questionnaire. Results: The Pearson correlation test showed a moderate negative correlation between working time as a coach and coach ages and Psychoticism (P); a moderate positive correlation between Extroversion (E) and Positive Feedback (PF) behavior; a moderate positive correlation between Neuroticism (N) and PF; a moderate positive correlation between N and autocratic behavior. The ANOVA revealed that coaches in the infantile category exhibited higher levels of N than those in the juvenile category. The Social Support (SS) given by the coaches of the junior categories presented superior levels to those of the juvenile category. The SS of the coaches of the infantile category showed higher levels than those of the juvenile category. Conclusion: It was concluded that certain personality traits are associated with the leadership characteristics of the investigated coaches.

“…The use of the differentiated approach on occupations with children-especially, with the younger ones at school age-is the most important catalyst of realization of their internal resources (Bakulev et al, 2006;Santos et al, 2018). In the theory and practice of work with children there are different criteria by which schoolchildren can be differentiated in groups, for example, on the basis of age, sex, temperament type, physical and technical training, and many other indicators (Holienka, Babic, Doležajová, Šelinger, & Musilová, 2017;Ion, Serghei, & Constantin, 2018;Shakhanova, Chelyshkova, Kuzmin, Silantyev, & Grechishkina, 2016). One of the effective criteria for schoolchildren differentiation in groups is the typological criterion, namely, nervous system force on excitement process.…”

The aim of the study is to define the influence of coordination abilities on attention stability development in first graders with different strengths of nervous system. Sixty 7- to 8-year-old schoolchildren from a usual comprehensive school participated in the research. Prior to the research, all children had been differentiated on equal 3 groups. The pedagogical experiment continued 7 months. During research there were changes in the groups. In the group KG, in the Shuttle run test, indicators have worsened from 10,3±0,6 s. to 10,4±0,6 s. (P>0,05), and in the methodic Bourdon Test indicators have worsened on 0,1 p. (P>0,05). In the group EG-2, in which schoolchildren were engaged taking into account the nervous system typology, there were considerable and positive changes. In the Shuttle run test indicators have improved from 10,3±0,6 s. to 9,7±0,5 s. (P<0,05), and in the methodic Bourdon Test indicators have improved on 1,4 p. (P<0,05). If the differentiated approach based on the typology is used, the indicators of movement coordination and attention stability will improve considerably during training.

“…Measuring SA by using x-ray-images of the left handwrist is currently regarded as the most objective method. 4,21 Due to ethical concerns such as exposing healthy children to (unnecessary) radiation, the implementation of this method in youth athletes is difficult and not feasible in some European countries such as Germany. 22 In response to this concern, several authors 23,24 suggest that images of the handwrist can be produced reliably on the basis of radiation-free magnetic resonance imaging (MRI) diagnostics.…”

The importance of considering information related to athletes’ biological maturation within talent identification and development processes is frequently emphasized by both sport scientists and practitioners. Although there is evidence for the use of objective diagnostics for assessing biological maturation, little is known about its subjective determinations by coaches. Such approaches are particularly relevant when scientific support is limited. Therefore, the current study aimed to compare a practical subjective approach (coaches’ eye) to assess biological maturity timing (BMT) with objective reference diagnostics (MRI). For this purpose, data were collected from 63 male elite soccer players of the U12 and U14 age group who were part of the German talent promotion program. Players’ BMT (i.e., skeletal – chronological age) was assessed by MRI and a subjective rating of two coaches. Data analyses revealed high-rank correlations ( rs = .55; p < .001) for the total sample as well as for U14 players ( rs = .65; p < .001) and moderate rank correlations for U12 players ( rs = .42; p < .05). Single case analyses showed substantial agreements between the diagnostics. However, particularly for U12 players, judgements did not always correspond with the MRI rankings. Although coaches seem to have the ability for recognizing the earliest and latest maturing players in the sample, inconsistencies exist in single cases, especially for players that were identified on-time by objective MRI diagnostics. Although utilizing subjective coach assessments as an alone-standing tool to assess a player's BMT is not recommended in applied practice, its use can be beneficial when applied in addition to common objective diagnostics or in circumstances where objective data are not available.
