Approaches and level of analysis of the physical demonstration of professional soccer players. Level 5 (part 8).
As the title says, I show you today some data related with the average duration of actions and pauses phases during professional soccer friendly games.
As commented during the videopost, remember that with this, and maybe with all sort of information presented in any study, it's of paramount importance to be cautious not only in how we use the info presented, but before this point, to be aware of the fact that depending on the methodology used for capturing the data, and specially the characteristics of the technology used, hard and software, we will find differences between studies, and sometime big differences which can send us to different "paths" when trying to use/apply them to day a day training.
In this sense, I have explained before the methodology used in the approach, and also some of the limits that present.
As an example and under my knowledge, directly linked with today's issue (duration of pauses) none of the known main international GPS system brands give us directly this info, so it means that we have to obtain it using our algorithms. But what it's really relevant is that under the same brand, depending on the version of the software, and as it changes the algorithm used to offer the actions duration, based on the changes of the characteristics of how the hardware captures the data, the result of the analysis changes!!!
Yes, what you read. So you can imagine the difficulty and the attention we have to put in our analysis when comparing data coming from different sources, methodologies, GPS brands, software versions ...
Appart from that, also remember that this data is the average of some friendly games monitored, so it means that in the analysis is also included the time when the game is stopped.

Following the last post in which I showed the data of the intensity of the soccer friendly games actions based on the speed demonstrated by the professional players of an Spanish team, you will see today the same approach based on the acceleration data.
In it you will find the average data of the intensity of the actions based on acceleration for soccer games, analyzed int two ways: the average of the maximum acceleration demonstrated by each player during each game (so data coming from just one action, the maximum acceleration one), and the average of all the accelerations demonstrated by each player in each game (so data coming from all the actions performed during the game). You will have the opportunity to compare it with the maximum value of acceleration (average for all the players of the maximum acceleration attained by each player during the season) for the team, so you can make your own conclusions ... if you want to share, they will be welcome!!!
Remember that all data we are using in this short of analysis highly depends on the system used, its specific software, the algorithms used, the filtering process of the raw data obtained, ... so have this in mind.

It arrives the moment to apply this intermittent approach to the analysis of soccer games: in this case, I show you the average data from the analysis performed with a spanish professional soccer team, in which we get data from all the friendly games performed during that pre-season and in-season (11 in total).
We have used the data obtained of all the players that participated in a complete 45 min of each game.
Logically this approach has its own limits (only 45 min, friendly games, preseason, in-season using mainly players "non-starters" ...) but it's a good reference to take in account.
Another big issue that we have commented in previous posts is referred to the GPS system; as you know, technology limits or guides us in a way ... but we have to try to use it in our direction ...
We have use 10 units from a competitive brand in that years (2007-2008), that unfortunately has not been able to adapt at the level required ... A little demonstration - confirmation of it is the paper of Buchheit et al. 2013 :http://martin-buchheit.net/2013/08/20/monitoring-accelerations-with-gps-in-football-time-to-slow-down/
Anyway, you can see here a little but important demo of how to apply the intermittent approach to the analysis of soccer games, and the data obtained as a reference ...

After exposing the basic characteristics of the intermittent approach for the analysis of the conditional demonstration of soccer players (not only ...), and in order to better understand the complexity of the relationship between these parameters (intensity and duration of actions and pauses), I present you what I call "the equalizer": it's just a simple explanation through a simile comparing what happens with these parameters and with a music equalizer, with a characterization of what happens during a "standard" soccer game ...
Under this approach we can better understand what short of demands are we proposing to our players, how are they really performing, ... but also there is an approach of how to distinguish between the different orientation of soccer training tasks, drills and exercises traditionally introduced in the same "endurance" bag, and of course, it help us to better understand why the traditional methodological approach to endurance development in soccer players (not only) has proposed different methods (running intervals, technical circuit "intervals", SSG "intervals", HIT, HIIT, RSA, ...) that all seems to provide an increment in the concept of endurance (specific ...?) and a development in players "specific"? fitness.
Hope you enjoy,
