Genética e melhoramento animal
Rink hockey like any other team sport game is necessary to have a mastery of the game object "the ball" and for this it is necessary that athletes do not have a deficient training steps in that process, because it is during their development, that the athlete is in an optimal situation to improve on this aspect of the game. The study objective was to identify which game model allows young athletes to have a greater number of interactions with the ball in rink hockey in the levels of “Under 8” and “Under 10”.
Our study sample consisted of 24 games: 8 games in the 3x3 model; 8 games in the 4x4 model and 8 games in the 5x5 model. The 24 matches are equally divided by the levels of Under 8 and Under 10 with a total of 88 children participating. For data collection instrument we used the deferred observation method where we proceeded to a descriptive analysis of the data to find the means, standard deviation and totals of: Shots, Passes, Interceptions and Goals. The Mann-Whitney and Kruskal-Wallis tests were used for comparisons and for correlations, the Spearman's Test was used to verify whether as the playing area available to the player increased, the player's actions increased as well. The 3x3 model obtained a total of 911 actions, the 4x4 model obtained 923 and the 5x5 game model obtained 799 game actions. The 4x4 game model obtained the highest total number of game actions in all levels analysed suggesting that the implementation of this model brings benefits to the athletes.
Introduction: Rink hockey motor learning and control needs deeply study to promote specific motor skills
acquisition and knowledge about the game interaction. The complexity of the game suggest the fragmentation to increase the opportunities of interaction among young athletes. Problem Statement and Approach: The
objective of this study was to analyse which game model allows for young goalkeepers to have more
interventions with the ball and, consequently, a greater number of interactions on the game. Material and
Methods: Our study consisted of 24 games analysed, divided in: 8 games in the 3x3model; 8 games in the
4x4model and 8 games in the 5x5 model. The 24 matches were equally divided in the levels of under 8 and
under 10 years of age, with a total sample of 88 children. For data collection instrument we used the deferred
observation method where we proceeded to a descriptive analysis of the data to find the means, standard
deviation and totals of Goalkeeper’s Interventions (GKI). Comparisons were made between game models and
athlete’s levels, using the Mann-Whitney and Kruskal -Wallis tests. Results: The results showed that, after the
analysis of the total game actions, the 3x3 game model obtained a total of 168 GI actions (21±3,5; p=0,021), the 4x4 model obtained 132(16,50±5,18; p=0,020) and the 5x5 game model obtained 123GI actions(11±2,61;
p=0,083). Discussion: According to the results, it was verified that there are statistically significant differences
between the 3x3 game and the 5x5 game in the “Under 8” and when compared the small-sided game 4x4 to the formal game 5x5 in the “Under 10 level” in the games analysed we perceive that the small-sided game brings more actions to the game, namely in the actions that the goalkeepers show. Conclusions: The 3x3 game model obtained the highest number of goalkeeper’s actions in both under(and under10, suggesting benefits for
improving the technical demands of these young rink hockey goalkeepers.
