Resumo
A vantagem casa contribui de forma clara para o desfecho final das competições desportivas. Este tema tem sido abordado de forma sistemática nos diferentes desportos, mas no Andebol os estudos são escassos. Assim sendo, o objectivo do presente estudo foi verificar a existência da vantagem casa no Andebol, em função do equilíbrio das equipas, identificar os períodos dos jogos onde as equipas marcam mais golos em função do local do jogo e por fim, identificar as estatísticas dos jogos associadas ao sucesso das equipas, em função do local do jogo. A amostra foi constituída por registos da estatística de 480 jogos pertencentes à fase regular da Liga ASOBAL (Liga de Andebol de Espanha) referentes às épocas desportivas 2007/2008 e 2008/2009. As variáveis foram analisadas em função dos períodos do jogo, divididos a cada 5 minutos e do equilíbrio das equipas, onde foram constituídos dois grupos, os JEQUI (jogos entre equipas equilibradas na classificação) e os JDES (jogos entre equipas desequilibradas na classificação). A vantagem casa no Andebol foi bem identificada no presente estudo, na medida em que as equipas da casa venceram 64% dos jogos. Quando confrontadas as equipas de acordo com o seu equilíbrio, nos JEQUI encontrámos valores superiores aos da vantagem casa global, ou seja, quando se defrontaram equipas de qualidade superior a vantagem casa foi de 71%, enquanto que nos JDES foi apenas 55%. As equipas vencedoras marcaram mais golos ao longo dos períodos dos jogos comparativamente às equipas derrotadas. Os períodos do jogo onde se marcaram mais golos foram entre os 25 e os 30 minutos e dos 55 aos 60 minutos, 6º e 12º período, respectivamente, com destaque para o último. No entanto, não identificámos nenhum período do jogo responsável pela vantagem casa. No que diz respeito à eficácia das equipas, apenas na finalização da zona dos 6 metros foram encontradas diferenças estatisticamente significativas.
The home advantage contributes in a significant way to the final outcome of sports competition. This subject has been systematic investigated in different sports, but in Handball, the studies related to this domain are scarce. Therefore, the aim of the present study was to verify the existence of home advantage in Handball, according to the team balance, to identify the game periods where the teams score more goals according to the game location and, finally, to identify the game statistics associated to the team’s successful according the game location. Archival data were obtained for the 2007/2008 and the 2008/2009 ASOBAL League (Spanish Handball League) season for all 480 regular season home and away games. The variables were analyzed according to the game periods which were divided in 5 minutes and the team balance, where cluster analysis was conducted to establish, according to the classification of teams at the end of each journey, two groups, the JEQUI (games between balanced teams in classification) and the JDES (games between unbalanced teams in classification). The home advantage in Handball was well identified in the present study. The home teams won 64% of the games. We found higher values in JEQUI (71%), that in global home advantage and lower in JDES (55%). Winning teams scored more goals in game periods compared to losing teams. The game periods where teams scored more goals were between 25 and 30 minutes and the 55 and 60 minutes, 6th and 12th period respectively, with special reference to the last one. However, we did not identify any period of the game responsible for the home advantage. Regarding the teams effectiveness, there were significant differences only in 6 meters shots.
