Approximately 70% of penalty kicks in men's professional football
are scored, hence being decisive in increasing the chances of
winning, since matches have only 2.5 goals on average. This study
assesses the improving chances for the goalkeeper to save penalty
kicks, using actual shot speeds in computer simulation and
considering actual and experimental data. Simulated kicks were
directed at the goal divided in nine areas. The goalkeeper's
movement was chosen to start at five different times before, at
and after the instant of the kicker's impact on the ball. Chances
of saving were analysed through logistic regression taking into
account area of the goal, ball speed and moment of goalkeeper's
reaction. Saves were found to depend essentially on the beginning
of the goalkeeper's motion according to the area. In the central
areas of the goal, saves were statiscally independent of ball
speed and time of reaction. The goal region further away from the
centre, where real shots are frequently saved, presented highest
dispersion. This suggests that saves depend mainly on the
goalkeeper's reaction time but also on the ball speed. Finally,
chances are low (but not inexistent) near the posts. (Mikrofiche-Nummer: 29632)
