Introduction: Measuring the peak velocity is crucial to individualize load management (external load) processes. However, the better condition (higher peak) to measure the peak velocity is not clear. Previous studies reported higher peak velocity data during soccer matches than in a 40-m sprint test. Purpose: Test the peak...

Introduction: The relationship between running performance (RP) and game performance indicators (GPI) was always a topic of discussion.

Sprint actions are crucial in soccer and there are three reasons that support this statement: (a) these actions are related to "game performance indicators" (Modric et al., 2019), (b) linear sprint is the most frequent action prior to the goal (Faude et al., 2012), and...

Introduction: Performance improvement with resistance training is a booming area in team sports. Weight training is essential for the development of specific game skills (i.e., change of direction, sprinting, jumping). In fact, there are many studies that analyze the design that strength training should have to...

Our professors Luís Suárez-Arrones and Ignacio Torreño talking about some differences between European and Chinese Soccer. They tell us about how they have implemented strength training in the Chinese league. These professionals also explain the methodological differences for the design of tasks in that continent because...

In this post, from the Fooball Sciene Institute we present a comment by Professor Jack Nayler about an important recent article published by Mathew Buckthorpe and collaborators of the Isokinetic group about the recommendations to implement hamstring injury prevention programs in elite football teams . Jack...
