A Study of Relationships among Technical, Tactical, Physical Parameters and Final Outcomes in Elite Soccer Matches as Analyzed by a Semiautomatic Video Tracking System:

The performance of a soccer team depends on many factors such as decision-making, cognitive and physical skills, and dynamic ever-changing space–time interactions between teammate and opponents in relation to the ball. Seventy (n = 70) matches of the Italian SERIE A season 2013–2014 were investigated to analyze the mean performance of 360 players in terms of physical (physical efficiency index; PEI) and technical–tactical (technical efficiency index; TEI) standpoints. Using a semiautomatic video analysis system that has incorporated new parameters able to measure technical–tactical and physical efficiency (Patent IB2010/002593, 2011-ISA), the correlation between these new variables and how much it relates to the likelihood of winning were verified. Correlations between TEI and PEI were significant (n = 140, r = .60, p < .001), and TEI showed a higher likelihood of winning than PEI factors (p < .0001 vs. .0001, CI 95% [1.64, 3.00] vs. [1.28, 2.07]). Higher TEI and TEI + PEI differences between the teams we...
