The Duration Of Actions At Maximum Intensity In Professional Football

The duration of actions at maximum intensity in professional football

In the literature, some discrepancy is evidenced when establishing the duration of the actions at maximum intensity (sprint) and the frequency to which they are repeated, since each author establishes different times; "The 4 seconds are rarely overcome" (Stolen, et al, 2005), "Each sprint has a duration between 2 to 4 seconds repeating every 70-90 seconds" (Bradley et al, 2009), "High intensity actions are Very repeated throughout the game, and are between 1.5 and 7 seconds, repeating every 30 to 40 seconds "(Cometti, 2007)," Sprints made every 90 seconds "(Bangsbo et al, 2006)," 33 % of these actions do not exceed 15 seconds ”(Zarzuela Martín, 2013). Despite these particularities, these authors reach the same conclusion "football is an intermittent sport where short -term and submaximal intensities are developed producing high physical demands". For this reason, the ability to repeat Sprint (RSA) becomes great importance in the development of the game, since this variable is immersed in determining situations that can define a party, as stated by Cometti et al. (2001) "The performance in short races could be an important determinant of the actions of winning matches in football".

Multiple studies agree that the ability to repeat sprines or RSA is understood as the ability to make a certain number of high or maximum intensity efforts, with a brief duration, less than 10 seconds, which are repeated in the time randomly ( in a dispersed or concentrated manner), interspersing incomplete recovery times, usually less than a minute and a half, which appear during the 90 minutes of the meeting (Arjol and Gonzalo, 2012).

It should be noted that this capacity is not presented in the same way in all players within the field of play, taking into account that there are certain positions where this type of actions predominates; “The strikers together with the midfielders are the game positions that show the greatest race distances while running during the game (Di Salvo et al., 2007; Rampinini, Coutts, Castagna, Sassi, & Impellizzeri, 2007b).

Energy substrates for (RSA) are changing, since mainly for this type of stimuli, the phosphagen and glucolitical system tracks are used, but given the characteristic of a party (time) it is necessary for the athlete to have a base Aerobics so that the demands required by anaerobic actions can meet.

Knowing the importance of this capacity, it is necessary to carry out exercises within the training to develop it; In this way the objective of knowing how to be worked is born, how it is being evaluated and also if it is truly being one of the variables that influences the competition.
