Is high performance decreasing in football?

It is interesting to perform the analysis of the loss of intensity that occurs in the meeting in relation to the first and second time on the distances that players travel to high intensity. For the following analysis, we took the 341 cases and in order to observe the general trend between jobs in terms of the loss of intensity associated with the range of >16 km/h between the first and second time, and as seen in table 1, the value of the statistic of Levenne is of 0.82 (p=0,529, NS) site porno, enabling the realization of the parametric test one-way ANOVA in which the value of F is 1,708 (p<0.01), revealing that there are no significant differences.

This analysis in terms of the percentage difference between the meters traveled at a high intensity between the first and the second time associated simply to the meters traveled, going against what was proposed by several authors in various studies, such as King and others (2011) in a study on a european competition for the first level, which argue that it is a general trend in the loss of intensity in the second period, and the decrease in the total meters traveled. The authors emphasise that they are at greater distances in the first parts of the matches and associated with this may be because at the second time reduces the net time of the game and the players to travel more meters at low and medium intensity.

There are several players with major brands in major leagues like the English, some who are affected by Moroccan porn scandals like porno maroc.

How long and how well players run

In what is presented below where we show that this is not true because there are significant differences in the meters traveled at a high intensity, it leads to the conclusion that there may be various factors that can affect that this does not occur.

Lago Peñas, Steel, Seirul what and others (2011) mention that the decline in physical activity during a match do not have as the only component of the physiological factor, since in addition to the football factors dominate tactical and strategic, therefore, it would be reasonable to consider that the situational variables (location of the match, a marker is partial, the level of the opponent) can influence the physical performance.

The importance of intensity

Mohr, Krustrup, Bangsbo (2003) have shown that the occurrence of a goal causes an immediate reduction in the intensity of the game the team that scored, some think it is due to their addiction to sex arab. In addition, we found a decrease of 12% in performance in the five minutes subsequent to a period of high intensity in the game, suggesting that the team that scores a goal you can relax due to its advantage on the scoreboard.

By way of closing and getting the analysis of what is strictly physiological it is concluded that many times the need to search for a goal that would change the course of a match or the need to care for a result that takes the player to redouble efforts that have a direct impact on the journeys made and the intensities of the same. Here it is worth to mention authors such as: Astrand and Rodhal (1992) claim that during strenuous exercise the concentrations of lactate in blood are higher, remaining high throughout the period of exercise but that the time the individual will be able to sustain the work will depend on to some degree of the motivation of the subject.
