Looking for Complementary Intensity Variables in Different Training Games in Football


Casamichana, D, Castellano, J, Díaz, AG, and Martín-García, A. Searching for Mathematical intensity Factors in different training Matches in football.

J Strength Cond Res XX(X): 000–000, 2018–The main aim of this study was to identify that combination of outside intensity training load (iTL) metrics catch similar or unique advice for different training match (TG) formats and official matches (OMs) in football with all principal component (PC) analysis. Ten manners of iTL were accumulated by 24 professional male football players using global positioning technology. A total of 348, 383, 120, 127, 148, and 207 individual files for small-sided possession matches, medium-sided ownership matches, small-sided games, even medium-sided games, even large-sided games, along with OMs, respectively, were studied. Principal component analysis was conducted on each individual game format. Extraction criteria were put at an eigenvalue of greater than one. Varimax rotation mode was used to extract more than one PC. For the very first PC, eigenvalues for each game format ranged from 3.89 into 4.45, which explained 39–44% of the information (i.e., variance) supplied by the 10 iTL metrics. For the next PC, eigenvalues ranged from 2.17 to 2.47, explaining 2-2 –26 percent of iTL details. For the 3rd PC, eigenvalues ranged from 1.41 into 1.98, explaining 14–20% of iTL info. This would imply that TG and OM have multidimensional requirements; therefore the utilization of just an individual iTL could potentially lead to an under estimation of their physical requirements. Thus, a mix of 3 iTL metrics is required during professional football game formats.
