Acute:Chronic Workload Ratio – Part 1
The ideal training stimulus maximises performance and simultaneously reduces the negative consequences of the training, i.e. the onset of fatigue and the risk of injury. The ratio between the workload carried out during the last week ("acute workload") and the average...
Power events: from theory to practice
Obtaining more powerful and prolonged high-intensity actions through the increase in the duration of the recovery phases, better if during the possession phase. This is the main goal in Empoli FC's work philosophy. The Fitness Coach Rocco Perrotta, with previous...
#gpexePeople – An interview with Prof. Paolo Barbero
Hellas Verona, promoted to Serie A at the end of last year and performing very well so far this season, is a gpexe customer from summer 2019. Prof. Paolo Barbero, fitness coach and a veteran gpexe user, explains why the gpexe system has been chosen by his new club....
a simple intermittent exercise analysis: gpexe vs traditional metrics (part 2)
In the first part of this article, we discussed the limits of acceleration events to describe the high-intensity phases in team sports and which gpexe metric can be used instead. The exercise analyzed takes place over the entire length of the pitch and consists in a...
the battle of thresholds and the misused concept of ‘high-intensity‘ (part 2)
What do we really analyse? In part 1, we dealt with the separate use of speed and acceleration to detect the most intense phases of the match and/or training. For both parameters, we highlighted the main limits of considering them separately. In the following...
Sprint: the same time but different profiles
The concluding paragraph of our previous article (https://www.gpexe.com/f-v-profile-game) was devoted to highlighting the fact that the assessment of the sprint ability of a given athlete via his force-velocity (F-V) relationship yields useful information on the...
Usain Bolt: metabolic power analysis of a top sprinter
A paradigmatic example of intensity in team sports. A brief Comment by Pietro E. di Prampero, Cristian Osgnach and Ivan Zadro We have recently followed, either personally, or via the press and the available media, several meetings and seminars dealing with the...
a simple intermittent exercise analysis: gpexe vs traditional metrics (part 1)
What do we get from the accelerations number? In this article, we will discuss the limits of acceleration events to describe the high-intensity phases in team sports and which gpexe metric can be used instead. The exercise analyzed takes place over the entire length...
the battle of thresholds and the misused concept of ‘high-intensity‘ (part 1)
What do we really analyse? I presume you’ve dealt with many tracking reports and, as it has often happened to me, you probably did not fully understand the meaning of the proposed thresholds. Indeed, I often mulled over the following question: “what happens to the...
F-v profile in the game
In the previous article, we have seen how the force-velocity profile and the maximum power are fundamental parameters for sprint capacities and in particular the related horizontal components (3, 4). We have also seen the relationship between force and speed during a...
UC Sampdoria: 10 gpexe people Q&As
Massimo Catalano, fifteen years of experience as a strength and conditioning coach in Serie A, from SS Lazio to Palermo Calcio, ACF Fiorentina and finally to UC Sampdoria with whom he has been working for 5 years, explains how he uses the gpexe system. He also shares...
High metabolic load distance (HMLD)
High metabolic load distance (HMLD): it’s not what it should be when dealing with the energy balance. The energetic variables based on the metabolic power model have become widespread parameters to assess team sport demands. In addition to the basic metrics suggested...
