Youth Physical Development in Football: How to Develop Young Players
Youth Physical Development I think this was the first time in the last year or two that I experienced a real writer’s block. It was surprisingly hard to just put something on paper. Maybe I was simply busy with other things, but still – it took me a while to get started again. Over the […]
Deceleration Load and ACWR
From Mechanical Cost to Match Week Monitoring in Football Introduction In season load monitoring, most teams track familiar external load variables such as total distance, high speed running, sprint distance, and accelerations. Increasingly, however, decelerations are emerging as a particularly informative signal, not because they reflect “more running,” but because they represent a distinct mechanical […]
Can We Have a Load Day During In-Season?
Yes, But Only If It Makes Sense For the last two years I’ve been teaching at the Croatian Football Federation on UEFA licensing with football and fitness coaches, and honestly, this is the part I enjoy the most. When you sit with coaches who are in the trenches every day, dealing with real players, real […]
Profiling Senior Soccer Players Using a Quadrant Model: Integrating Concentric Impulse and Eccentric Braking Impulse from CMJ Testing
In this article, we introduce a quadrant model that leverages two key force-time metrics from countermovement jump (CMJ) testing — concentric impulse (CI) and eccentric braking impulse (EBI) — to create a functional profile of senior soccer players. Force profiling allows us to move beyond general metrics and look at how athletes express force. As […]
