In football the chronology of the game is (team) communication, (individual) decision making and execution of decision, as often as needed for as long as needed. With the Sonda Sports Tracking System you can monitor the “execution of decision” part. This will give you information about patterns of this aspect of the “football load” – a crucial aspect for the modern coaching staff to make better decisions.
Being a football coach you strive for optimal training sessions to prepare for the next game but also to develop the team on a more long term horizon. You need to understand how to plan – execute – evaluate – and plan again. This goes for team level periodization but even more so on individual level periodization. In this process LOAD and RECOVERY are two key areas of attention. In Örebro SK we use Sonda Sports GPS to better understand what type of loading patterns the team and the individual players get from day to day, week to week and month to month.
We use the Sonda Sports GPS Tracking System every training session and every game. Handling of the kit, GPS unit, heart rate belt and vest has become a natural thing for the players. The player grabs the vest on his hook and then he puts the GPS unit and heart rate belt on by himself. It works very smoothly. During the training the GPS are automatically synced with the stadium WI-FI and after the training one of the coaches can right away start to create so called sections on the plattform, which means the creation of exercises corresponding to the timeline of the daily activity.
In overview we have created three main types of report areas:
- Game reports
- Training reports
- Individual reports
All of them contain sub reports. Each microcycle begins with a meeting where the last game report is presented. This report is then connected to the tactical game report (do we behave the way we want?) with comparisons between starters, subs, positions etc. Then we go into individual reports:
- Acute vs Chronic workload (7 vs. 21 days)
- Last three weeks of load vs the three weeks before
- Injury report (problems for the player)
This leads to discussions for the upcoming microcycle; will someone need to do more or less compared to what he has done before and/or compared to what the group will do? The aim is always to solve these questions within the football training exercises and games i.e. football actions. But as an exception to the rule, sometimes we also need to add isolated exercises i.e. basic actions.
After every training, a training report is put together. We look at the absolute – and relative individual game values for each player and each parameter for the session. The report shows the parameters we have chosen (Total distance, Distance 20-25km/h, Distance >25km/h, Accelerations, Decelerations, Playerload, sRPE*duration and a “multi mechanical number” based on studies conducted by Owen et al. The multi mechanical number is the average of all the 7 mentioned parameters, based on the relative game numbers.
We always compare to the corresponding training session in the previous micro cycle (and we also compare to all previous corresponding training sessions and put this in a different report). This is done on a team level for all who joined 100% of the session. The report also shows a target of the day, both on team level and on individual level. This target is based on the multi mechanical number. The report also contains an overview for each parameter the last 28 days, as well as the updated ACWL 7 vs 21 days.
Based on this report and the meeting at the start of the micro cycle we are now better prepared to discuss and create exercises, volumes and individual periodizations for the upcoming day. In the next morning we collect wellness and based on this we get feedback on how the session from yesterday has affected the players. The wellness data we collect are the following:
- Numbers of hours slept
- Subjective sleep quality
- Subjective nutritional quality from yesterday
- Subjective freshness
- Pain (where?)
After the training the next report is created and loading patterns are monitored and feedback is given together with reflections in a staff meeting post training.
During the micro cycle we also look at the different sub reports created in regards to individual players. We try to understand loading patterns for each player, especially the ones who we decide were going to do more or less during the week. This also (especially) includes injured players who are in the return to play.
All of this is thanks to the Sonda tracking system.
