La holografía como recurso didáctico para la enseñanza de contenidos de geometría en primaria
2021
En el presente artículo se analizarán los usos y beneficios que reportaría trabajar con hologramas como material didáctico, como así demuestran los estudios de Ghuloum, Escrivà y Orcos. A través de estas propuestas didácticas se refuerza la idea de que el uso de la técnica de representación en tres dimensiones puede beneficiar al alumnado en la adquisición de los contenidos geométricos presentes en el currículum oficial. El ámbito de la geometría ofrece una amplia gama de contenidos que posibilitan trabajar mediante técnicas de representación gráfica. Cabe destacar, por otra parte, que ahora los estudiantes de educación primaria están socializados en el acceso y uso de imágenes de todo tipo…
Analysis of different key behavioral patterns to score in elite taekwondoists according to the weight category and gender
2021
Traditionally, research in taekwondo has focused on athletes' overall performance considering the entire sample of the tournament or analyzed selected bouts while ignoring behavioral differences of athletes according to their gender and weight category. Thus, the aim of this study was to analyze the behavioral patterns used to score points in the London Olympic Games according to gender and weight category [fin (FW), feather (FTW), light (LW), and heavy (HW)] of the athletes. A total of 24,940 actions were analyzed by using observational methodology, a mixed method methodology where lag sequential and polar coordinate analysis were applied. Different patterns could be seen in the actions pe…
Offensive Transitions in High-Performance Football: Differences Between UEFA Euro 2008 and UEFA Euro 2016
2019
[Abstract] Coaches, footballers and researchers agree that offensive transitions are one of the most important moments in football today. In a sport where defense over attack dominates, with low scores on the scoreboard, the importance of these actions from the offensive point of view becomes very important. Despite this, scientific literature is still very limited on this topic. Therefore, the objectives set out in the present investigation have been two: first, by means of a proportion analysis and the application of a chisquare test, it was intended to describe the possible differences between the offensive transitions made in the UEFA Euro 2008 and UEFA Euro 2016; then, through differen…
Possession Zone as a Performance Indicator in Football. The Game of the Best Teams
2017
Possession time in football has been widely discussed in research but few studies have analyzed the importance of the field area in which possession occurs. The objective of this study was to identify the existence of significant differences in the field zone of ball possession between successful and unsuccessful teams and to acknowledge if the match status modulates the possession model. To this end, 2,284 attacks were analyzed corresponding to the matches in the final phase of the UEFA Euro 2016 France, recording possession time and field zone in which possession occurred. Video recordings of matches were analyzed and coded post-event using notational analysis. We have found that successf…
Possession in Football: More Than a Quantitative Aspect – A Mixed Method Study
2019
The aim of the present study was to identify and differentiate the factors that determine the possession times of successful and unsuccessful elite football teams, with the purpose of identifying a more effective possession model. For this, match corresponding to the round of eighth-finals, quarter-finals, semi-finals and final of the 2016 UEFA Euro France in which 2,636 offensive sequences occurred, were analyzed. Video recordings of matches were analyzed and coded post-event using systematic observation. The performance indicators recorded and analyzed were: phase; match period; type of start-up; interaction context; intention; field zone; possession time, passes, attack outcome; match st…
Why do female and male taekwondo athletes win the bout? An analysis based on the Olympic weight category and the result of the bout
2020
Combat sports such as taekwondo, where athletes compete against an opponent require control of technique and tactics, as well as knowing the optimal performance of opponents to win the bout. Therefore, the aim of the present study was to analyse the Olympic competitors (London Olympic Games), according to the weight category (fly, feather, light and heavy) and according to the performance in their fighting (winner vs. loser) in each gender. An observational methodology was used, following a nomothetic, follow-up and multidimensional design of 302 individual performances. The statistical analysis used an ANOVA and T Student test for comparing frequencies. The results obtained indicate signif…
Technical, tactical and spatial indicators related to goal scoring in European elite soccer
2020
The aim of this study was to describe the technical, tactical and spatial indicators related to goal scoring in elite European soccer, considering the type of defence and the positioning of the opponent. For the analysis, 8 tactical dimensions related to the final actions in 380 sequences that led to goal during the UEFA Champions League were evaluated by observational methodology. 75.9% of the goals were scored from open play and 24.1% were scored from set pieces. Collective actions produced 51.6% of the total goals while individual actions produced 10.5% of goals. Regarding the penultimate action, crosses were more frequent against organized defences, while passes in behind the defence, o…
