Home advantage was defined as the fact that home teams win more than the 50% of their matches(Courneya & Carron, 1992). The aim of this work was to investigate the home advantage in the ACB league and identifythe game-related statistics which best discriminate home and away teams. The data were obtained from the SpanishBasketball Association for the period 2007-2008 ACB league (n= 306). Game related statistics were normalized to 100 ballpossessions. In order to compare game related statistics in home and away teams, a discriminative analysis was employed.This analysis identifies the game related statistics that best discriminate between home and away teams. The functionobtained was interpreted with the structural canonical coefficients (SC), with values higher than |.30|.In the 2007-2008 ACB league, the home teams won the 55.22% (n=169) of the games. The analysis identifying thetwo-point field goals made, blocks made, dunks, the defensive rebounds and the assists as common to the mean vectorsthat discriminate home teams in all games. Blocks received contribute to discriminate away teams in ACB league.These results could be used by the psychologist who works with the team. They must design specific programs todecrease anxiety levels, and to improve motivation and concentration levels in basketball players before a competition.
