With the aid of a mathematical model, Sérgio Augusto Cunha, professor of Physical Education (ETF), State University of Campinas (Unicamp), is developing a system to analyze football goalkeepers jumping through computer visualization.

According to Cunha, football goalkeeper deals with very specific characteristics of fitness, technical and tactical. The drive to run the defense goes through phases of anticipation, the first step and jump. The study sought to define parameters for the jump has better performance.

The focus of the study was the power of the jump variable important for football players and athletes from other sports. The mathematical model used involved a routine described in Matlab software that makes calculations with arrays and lists basics how to determine maximum value of the curve and area under the curve.

Cunha analyzed the momentum and the call force peak. The jumps were made in force platforms, which, according to the researcher, can be brought to training camp for athletes confer technical and performance in terms of the analysis of the force curve in time and the area under this curve.

The experiments were performed with six amateur volunteers (four goalies and two goalies not), each performing nine jumps. Wedge with the collaboration of the group of Professor Walter Herzog, University of Calgary, Canada, where did postdoctoral.

Preliminary results of the study indicate that the goalies have a much higher energy use at the time of contact with the ground than non goalkeepers. When the pulse are, for example, brake much less movement, thanks to the art.

Cunha want to put into practice the system with the analysis of jumps of athletes from professional sports teams. We will make analyzes of jumps using Brazilian goalkeepers, said.

The researcher is improving, with the help of Professor Ricardo Torres, Institute of Computing, Unicamp, the quantification of patterns of curves heels. A new study should address the jump in time cabeceio in football, made by a guiding wedge in order to better understand how to train the power of the lower limbs.
