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.

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>

As bolas paradas no futebol jovem: a opinião dos treinadores
Publication . Loureiro, Nuno; Teixeira, Eduardo; Costa, João Paulo; Prudente, João; Prudente, João Filipe; Sequeira, Pedro
As bolas paradas têm ganho importância no futebol nas últimas décadas devido à sua
influência no resultado final dos jogos. No entanto no futebol jovem ainda são poucos
os estudos neste âmbito. O objetivo deste estudo foi auscultar a opinião dos
treinadores acerca da importância das bolas paradas no futebol jovem, nomeadamente
as diferenças relativamente ao futebol profissional, os exercícios utilizados no treino,
a importância do lado estratégico e como potenciar o aparecimento de especialistas
nestes lances. Foram entrevistados seis treinadores com experiência na primeira liga
portuguesa de futebol, tendo sido utilizada a entrevista semi-estruturada como
instrumento de recolha de dados. A análise e interpretação do conteúdo das
entrevistas permitiu identificar que os treinadores consideram que o treino destes
lances no futebol jovem deve ter características diferentes do futebol profissional, que
os exercícios de treino no futebol jovem devam ser direcionados para a aprendizagem
do jogo e dos seus princípios. Quanto ao lado estratégico indicaram que é mais
relevante nos escalões mais avançados e nas competições nacionais. Para a
potenciação do talento existe a necessidade de maior volume de treino destes lances
específicos e também treino individual.
