# defensive and offensive tactics and strategies in handball

Discover our research outputs and cite our work. [9] summarized the successful approaches in different types of sport where t-patterns were used.

In previous studies we already used artificial neural networks to identify offensive [24,32] and defensive [33] playing patterns in team handball separately.

23, Mathematical Modelling in Sport and Human Movement Science, pp. However if it is directed by a defending court player, the ball will go to the attackers’ hand. The proposed method augments tactical analysis for coaches and can support them in the development of offensive and defensive tactics in game preparation. The goalkeeper is allowed to touch the ball with his/her feet, but only during saving the goal, not to direct it out of the goal area or control the ball unnecessarily. In case the attackers miss to put the shot into the goal and the ball goes over back line, then they lose the ball. Before we get into the rules of the game, there is a quick summary of the initial part of the game that demonstrates how the ball gets passed between the players and is defended by the opposing team. The goalkeeper gets punishment, a free throw to the opposition team, if he/she comes out of the goal area with the ball on his/her hand. By classifying types of creativity learning, they showed the ability to analyse and simulate creative performance which may support trainers for optimizing individual training programmes. registered in England (Company No 02017289) with its registered office at 26 Red Lion During the training process, the artificial neural network with a dimension of 400 neurons relates similar data sets to neurons. Puis va se replacer vers l’autre arrière sans ballon. Cependant, ici il n’y a plus deux personnes qui travaillent mais 3.

Whereas, by going into the goal area with the ball, the opposition gets a penalty from 7mts from the goal post.

As example, the chance to score with the offensive cluster #2 against the defensive cluster #1 was 6.43 times higher than against defensive cluster #2. Based on experiences from the offensive network, the parameters of the artificial neural network for the defensive analysis, which had also a dimension of 400 neurons, were set at 9.0 for the parameter tolerance and at 65% for the parameter similarity resolution. The position data of these action sequences were then analysed by means of artificial neural networks software (DYCON [26]), in order to find typical patterns of offensive behaviour. Info. Don’t try to get it all back at once Need for base runners, not home runs. Result of the training process of the artificial neural network for the defensive position data. Furthermore, centroid positions and the surface area, changes in sub-group behaviour, and relations between groups and between teams were examined [14–18] for a better understanding of the inter-group and inter-team coordination. Clusters are represented by neurons with the same number. In the analysis of sports performance, the application of computers for notational analysis enables the processing of a large amount of game elements [2].

All tactics require judgment in application. Grunz et al. For each offensive pattern, the DistShotDef parameter was compared between the corresponding defensive patterns. Ce croisé, comme son nom l’indique va faire croisé deux attaquants. Le croisé simple avec ballon est très souvent utilisé au handball dans toutes les combinaisons un peu plus poussées. Former approaches of artificial neural networks neglect the existence of this rare and original behaviour. Il parait évident que ce style d’attaque a lieu la majorité du temps au handball. To the best of our knowledge, the interaction between offensive and defensive behaviour in team handball has not been modelled so far. Performance & security by Cloudflare, Please complete the security check to access. Due to the huge amount of different game situations and therefore unlimited different position combinations, classic statistical methods and above-mentioned approaches have limited applicability to gain suitable results. Penalty is awarded if a player passes the ball to his own keeper when they are inside the goal area. Centre Back Out − The player who plays in this position are also known as the playmaker. On the other hand, not only the position data of the ball-possessing player, but also the position data of his/her teammates should be considered. Schematic display of the ball path during the last five passes prior to the shot [P: pass; S: shot; solid line: running path; dashed line: passing path]. The team which scores highest number of goals within the given time period is considered to be the winning team. The tolerance defines the similarity within the neurons, while the similarity resolution defines the alignment of neighbouring neurons to a cluster.

In another approach, Fonseca et al. » Les rentrées de pivots First of all, the referees decide which team will start the throw by the process of toss. L’attaquant avec ballon va chercher son partenaire tout en attaquant un intervalle. Les techniques offensives au handball. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Therefore, the aim of the present study is to merge the models of offensive and defensive behaviour in order to analyse the interaction between opposing teams. Handball involves passing of ball from one player hand to another progressively with the objective of scoring goals. Since the subsequent analysis process by neural networks is done quickly, it is conceivable that results may be available between games in tourneys or even within half-time breaks in the future. The assignment of the data sets to the neurons is adjusted by the parameters ‘tolerance’ and ‘similarity resolution’. (2017). As successful behaviour is not restricted to the quantity of formations occurring in games, creative behaviour becomes important in order to produce rare and original decisions. In a first step, they pre-processed the huge amount of position data by means of the software tool SOCCER to get playground-independent position patterns. 1. An attacker or defender is not allowed to cross the goal area while playing in order to get some advantage by short cut movement of his own. is the lack of possibilities to disturb preparatory combinations and the lack of possibilities to closely guard the attackers shooting from a long distance. L’attaquant sans ballon après avoir fait un engagement sans ballon dans son intervalle, va se désengager pour ensuite passer derrière l’attaquant avec ballon. If the goalkeeper directs the ball over the back line while saving the goal, it will remain with the goalkeeper. Differences regarding the DistShotDef parameter between the different defensive patterns of a corresponding offensive pattern were analysed by means of t-test and analysis of variance depending on the amount of defensive patterns. the Open University A cluster itself then represents a typical pattern within the data set. Try not to lob the ball or make long passes as it gives the opposing team a chance to take possession.

For semantic interpretation each neuron of the third level network was examined by an expert. While free throw is awarded, there must be minimum 3mts distance between a defending player and an attacking player for which the free throw line is always marked at 9mts from goal so that there will be a gap of 3mts between the player attempting to shoot at the goal and defending goal-keeper.
