ANALYSIS OF POLAR COORDINATES IN FOOTBALL GOALKEEPERS: GENDER DIFFERENCES
Abstract
The principal objective of this study was to determine the activity profile and the physical requirements (total distance traveled, speed) and tactics (displacement by heat map) in the competition in the goalkeepers of university soccer in Bogotá over 64 games, implementing GPS devices. The treatment of statistical data was carried out using the R program in different phases; descriptive analysis, an analysis of variance, and a descriptive spatial analysis for the polar coordinates. The results showed that there are significant differences between the distance traveled in each of the speed categories and between the distance traveled by men and women with analysis of variance (category 1: 0.016; category 2: 0.0088). Finally, the activity profiles of goalkeepers should consider locomotion categories that establish speed ranges specific to their positioning needs.
