The purpose of this study was to analyze the final actions in a sports of racquet and wall called “Olympic frontenis”, comparing the distribution of scrimmages and the incident that had in the space where the ball was sent. This sport counts on vertical spaces of impact of the ball and is played 2 vs. 2, what differentiates it of other sports of racquet and wall as the squash or the racquetball. 1226 points in male category were recorded and the final action of each one of them was analyzed. A specific software for the two-dimensional analysis of the images was designed and the management of the data. A study was carried out of confiability, to determine the degree of agreement interobserves and intraobserves and of agreement arrived at by consensus to priori among the observers that surpassed the levels required (>80%). Thanks to the Test of Chi-Square of Pearson and of reason of verisimilitudes, the meaning was obtained that is produced in the crossing of variables. The condition of validity to be able to apply the test is that exist not any frequency expected <5.
