ABSTRACT

The purpose of this study is to verify the physiological effect and describe the intensity of training in response to internal and external loads, through Session Rate of Perceived Exertion and Speed High Intensity Distance in Meters reports, on professional soccer players engaged in weekly training (199 Sessions, 43 weeks) and league games (32 official matches). Twenty-two male professional soccer players (n = 22) of the Italian national championship under-19 are involved in this study during the season 2014-2015. Daily, Weekly and Monthly RPE (perceived exertion) Session (Borg CR-10 Scale) is a good indicator of the amount of work done: training time multiplied by perceived effort (TL = Training Time × RPE). With Arbitrary units (a.u.) produced by the individual and used for team-based data analysis, we analyze the intensity produced by workout depending on the working time. Furthermore, by means of global positioning system technology (K-Sport, Montelabbate PU, Italy 10 Hz), we statistically established the existing relationship with high intensity speed distance (> 16 km/h) and session rate of perceived exertion to describe how the internal (represented by the sum of the stresses that the body undergoes an external load; is strictly subjective) and external loads (the objective quantification of the means used in training km routes, running speed, slope, type of recovery), are correlated (r = 0.87, p <0.01, 95% CI). The statistical analysis highlights how these methods are suitable to quantifying the high-intensity work done by the soccer player during the workout and the game.
