to deepen our performance analysis model
The articles related to the technological and scientific aspects of the gpexe system, with a main focus on the performance analysis model, are available to the whole gpexe community.
Other contents are available into the gpexe academy, for the gpexe users only.
Acceleration: overcome its limits towards a new mechanical analysis.
The typical way to assess the acceleration capacities is to perform a maximal sprint starting from the blocks. This would not always be truthful for the football player, who rarely starts from a standstill. This study by Sonderegger K, Tschopp M and Taube W (2016) is...
Metabolic Power Profile in Soccer based on GPS measurement concept and caveats
In 2020, we introduced two new gpexe web app tools designed to profile players. Precisely, to test them without testing them. Parallel to the Acceleration-Speed Profile, we have implemented a Metabolic Power Profile following the same "in-situ" concept, therefore...
Worst case scenario: a practical use of Rolling Window Peak on the rugby field
The use of GPS in professional rugby is widespread and allows the Strength and Conditioning team to collaborate closely with the coaching staff, ensuring that trainings are replicating games from a physical, technical, tactical and psychological perspective. Benetton...
The decline of the regular match cycle
From season to season, it is tougher for fitness coaches to refer to a typical training week (Sunday - Sunday). We decided to dive into the tricky subject of the match cycles deeply. We checked firsthand what happened in the Serie A 2020-2021 season to 8 of our gpexe...
Acceleration-Speed Profile (ASP) in the Return To Play process: which contribution?
Return To Play: on-field monitoring. That's the speech's title of our mate Michele Turloni, who has been our guest in the "4th Football Analytics & Talent Identification Online Event" organised by Vonlanthen Group in March. For 10 years in charge of injury...
How easy is it to stumble over acceleration and deceleration?
We had a look at the match data of a Serie A player. We analysed accelerations and decelerations by using the standard criteria (acc above a threshold of ± 2.5 m/s² for more than a minimum time, which duration is above 0.5 s). In the following figure, there are the...
Effects of seven weeks resisted sled sprint training on Acceleration-Speed Profile in professional male rugby players
Heavy sled training is one of the most effective training interventions to improve the horizontal force, i.e. the forward acceleration. This article relates to the practical experience of Benetton Rugby during the last season. Introduction Many team sports,...
The performance explained through MPEs – Part 2
"Metabolic Power Events" is part of a series of webinars held by Cristian Osgnach to go deeper on the workload analysis and the concepts of metabolic power and high-intensity through specific examples on the field. In the first part of the article, we...
The performance explained through MPEs
"Metabolic Power Events" is part of a series of webinars held by Cristian Osgnach to go deeper on the workload analysis and the concepts of metabolic power and high-intensity through specific examples on the field. We know that MPE is often considered a smart...
Internal and external training load in soccer: which relationship?
For a training organisation, monitoring the training load is of paramount importance. The aim of this study is to investigate the relationship between internal and external load indicators and to propose a new method for monitoring actual physical fitness. The results...
Workload monitoring: why you cannot consider HSR as the only measure of high intensity
High-speed is widely used in team sports to assess the so-called high intensity. For a decade, lots of papers have been written on this topic, but the goal of researchers has changed over time. Let's start from the very beginning and follow the chronological sequence....
The limits of acceleration
introduction. I have covered less distance but the number of my accelerations is greater!” - this could be the comment from the majority of players while looking at the performance report after a training session or a match... and often the same would be the view of...
