It is a similar one that I had already provided for the World Cup 2014. Therefore you will find the information on how to cut and fold it on my YouTube channel HERE.

Or you can download the file and follow the instructions on the second page instead. I am little bit sorry that the file is not the smallest.

The report can be downloaded HERE.

As a consequence we have also provided a 30 meter sprint data collection and analysis sheet, which we have updated and improved the visibility of the average 30 m sprint values in our graphs.

Additionally, we have added a 20-meter sheet.

Please use this link to the download section.

Additionally we have given information about what to test, however did not provide any “help” or suggestion on how to do that. As a consequence we will provide a data collection and –analysis sheet.

Given the fact that acceleration is a very important aspect in football, its monitoring and training seems crucial. Latter is of particular interest for coaches, however, there are multiple possibilities to train for speed, which most likely result in different improvements on sprint performance and therefore affect monitoring. Sprinting can be defined as acceleration (herein it is also possible to discuss “first-step-quickness”), maximum speed, and maintenance of speed. All components have importance in football and therefore should be monitored and trained.

For example it was seen that acceleration (0-10 meters) was correlated to maximum strength with 0.9 (= correlation coefficient “r” = 0.9 identicates a nearly perfect correlation, with 1 being perfect – but also unrealistically in a real-world setting). However, the correlation was less strong (r = 0.7 which is strong) on 0-30 meter sprints (5 - see references below) in football players. Similar, acceleration and maximum speed was only correlated with a coefficient of 0.6 (3), which suggest that the two are separate components in elite football players. Additionally, knee extensor torque at 240 degrees per second was the strongest correlation with acceleration (0-10 meter) sprint performance (4).  As a consequence it seems that not only maximal strength but other physical qualities are important on a 30 meter sprint. (We also believe that the correlation of 0.7 also derived from the fact that usually players that are fast over 10 meter are quick over 30 meters as well, just as a result that the time advantage from 10 to 30 meter distance will still exist).  However flying distance (such as 10-20, or 20-30) seems to be more related to stiffness and some sort of power utilization (power absorption in the eccentric phase of running and utilization in the concentric phase  stretch shortening cycle) (1). For example, hopping was the best predictor of the changes in speed between individual phases (such as acceleration and maximum speed). Additionally, maximum velocity was correlated with stiffness (r = 0.7) but not with the acceleration phase (2). Therefore is it important to have a more differentiated analysis on sprint performance as it has consequences on training as suggested by Little et al. (2005).

In order to do so, we have provided a first file, which includes sheets to enter AND to analyze sprint performance. Feel free to use.
