Behaviours of children and young people in sport are influenced by the attitudes and behaviours of adults.
Behaviours related to fair play, respect for others and rules, conveyed through coaches' example are
important, at a time when young people are his own identity, tending to identify with figures such as coaches
and where the maxim "does what I say and not what I do" does not work. The objective of the study was to
identify the importance that coaches attribute to values and attitudes in sport, and to study the association
between the trainer's biographical characteristics and the relevance of these values and attitudes in sport
and competition. A total of 30 volleyball coaches (21 men and 9 women) were interviewed, with a mean age
of 39.23 ± 10.57 years. To collect information on the selection criteria, we used the survey adapted from
Cardoso, (2007). The study project was approved by the scientific committee of the Department of Physical
Education and Sport and ethics committee of the State University of Amazonas. For the analysis of the data,
mean and standard deviation statistics were used. In the normality of the variables, the Kolmogorov-Smirnov
test was used and the association between variables was the Chi-square test for qualitative variables and
Spearman correlations in quantitative variables. T-Student was used to determine differences between
groups in variables with normal distribution. Most of the Amazon coaches attach significant importance to all
factors related to values and attitudes in sport and competition among young children.

When it comes to children's sport, it is important to select these athletes in competitions, so that everyone
has the opportunity to compete according to their level of development and abilities. The objective of this
study was to analyse the selection process used by the coaches. The sample used was 30 volleyball coaches
(21 men and 9 women), aged between 21 and 62 years (39.23 ± 10.57). In order to collect information on
the selection criteria used, the study was adapted from Cardoso, (2007). The study project was approved by
the scientific committee of the Department of Physical Education and Sport and ethics committee of the State
University of Amazonas. The Kolmogorov-Smirnov test was used to analyse the data and the mean and
standard deviation statistics were used. The Kolmogorov-Smirnov test was used and the Chi-square test for
qualitative variables and Spearman correlations were used in quantitative variables. T-Student was used to
determine differences between groups, the Anova of repeated measures to analyse differences in the
relevance attributed by the coaches to the criteria between different levels of training. The results showed
relevant data such as the predominance of observation of physical education classes in children and
youngsters (76.7% and 63.3%, respectively) and the application of tests in the levels of initiates and juveniles
(40% and 50% % respectively). There were no divergences between the selection methods considering the
characteristics of the trainer (p> 0.05)
Analysis of the influence of the numerical relation in handball during an organized attack, specifically the tactical behavior of the center back

In the last decades, observational methodology has been widely used in scientific research
in sport, namely in the study of team games like handball, due to its characteristics.
Handball, in addition to being a collective, complex, dynamic, and interactive sport, has
its own characteristics and demands a performance analysis that takes into account the
context and interaction between different factors and variables. The present study analyzes
how the different numerical relations in an attack can change the center back’s patterns
of tactical behavior. Observational methodology and a mixed ad hoc instrument combining
field format and category systems appropriately validated by experts were used. Data were
taken from 20 matches involving teams classified in the first four places in the 2017 Men’s
World Championship. These were recorded from TV broadcasts, and the total number of
offensive sequences carried out in an organized attack game method (n = 990) was
analyzed. In each of the sequences carried out in an organized attack, the numerical relation
in attack or defense was observed and recorded. In addition to this, it was verified whether
the attacking team maintained or replaced the goalkeeper by a field player in the attack.
Both sequential analysis techniques with lags, prospective, and retrospective, as well as
polar coordinate analysis, were used. Results have shown that there are different behavioral
patterns of the center back in the three different situations of numerical relation. Another
element that stood out was that in numerical equality with the defense and no goalkeeper
at the goal, the center back opted for greater security and less risk of loss of the ball.
The effectiveness of a tactical games approach in the teaching of invasion games

Abstract:
Purpose: The main purposes of this study were (a) to assess the effectiveness of the tactical games approach on
students’ invasion game performance when compared to the technique-oriented approach, and (b) to investigate
whether there was a difference in motor engagement time (MET) between the both pedagogical approaches.
Method: The sample consisted of 79 students (13-16 years), allocated to the Intervention Group (IG) following
the tactical games protocol, or to the Control Group (CG) following the technique-oriented approach.
Psychomotor performance was assessed by the Game Performance Assessment Instrument. MET was assessed
by direct observation. Results: Both pedagogical approaches promoted off- and on-the-ball movement over eight
consecutive weeks. Comparing the effectiveness of these two teaching approaches, no difference was found.
However, collapsed across the two time points, students had better on-the-ball decision-making in the tactical
games approach, as well as more MET. Conclusion: Continued replication of this research including long term
follow-up is necessary to further strengthen the generalizability of these findings across alternative school
contexts.
Analyzing the influence of playing time and partial score on the tactical behavior in the duel 2 vs 2 in the offensive process in handball, using the polar coordinates technique

<p><span style="font-size: medium;">Different studies have referred that the playing time and partial score, as well as the interaction between these two influences the behaviors of players and teams. With this study we intended to realize the complex reality of tactical behavior in the attack in Men´s European Cup, by detecting behavior patterns and linking them to playing time and partial score.</span></p><p><span style="font-size: medium;">We used the observational methodology and for data analysis we used the polar coordinates. An instrument of observation has been constructed <em>ad hoc</em> and validated. The tool optimization included the quality data control, using the analysis of intra and inter observer reliability by Cohen's Kappa index (range between .85 and 1), beyond the application of generalizability analysis (G indexes are suitable for all models estimated) confirming the instrument reliability. The sample contained all of 2<em>vs</em>2 situations that occurred during the organized offensive process in numerical equality 6<em>vs</em>6, in sixteen games (n = 390). </span></p><p><span style="font-size: medium;">As main results we can refer that the playing time influenced the decision-making in relation to the tactical means used, excepting the last ten minutes, where no patterns were found. The results also show that there are fewer behavior patterns when the score is a draw.</span></p>
