WHY measuring force application on the pitch matters ?
-
HOW can we measure (estimate) force application ?
-
WHAT can we practically DO with these models ?
Why IS IT IMPORTANT ?
Strength is KEY !

Strength: 20’ - ~50 Reps totals.
Po: 4v4: 2 x 4-min
Gs: 4v4+GKs (30x25m) 4-6 x 3-min
Horizontal alternation in specificity
“the three main training (acquisition) days in the week will alternate the physical fitness component.”
(Delgado-Bordoneau & Mendez-Villanueva)

MechW
--------
Velocity-change load
Tight work analysis
ForceH = Masse * Acc H
MechW = ForceH only when
Acc/DecH > 2 m.s-2
Force Load
--------
Foot-strike analysis.
Accelerometer-based metric
Force Load = Mass x Acc Z

Mechanical work can be under loaded or at least matched using various periods of 8v8 PO.
“4v4 (<5-min) and (to a lesser extent) 6v6 SSGs (2-15-min, CD) can be used to overload MechW intensity.”
(Lacome et al. 2018)
“SSGs are not a one size fits all training weapon when it comes to players loading.”
“ Planning position-specific unloading strategies or top-up exercises are likely required to equilibrate players loading relative to game demands when using SSGs.”
(Lacome et al. 2018)
Real-world ‘optimal’ processus
Where it starts to be interesting…
Understand THIS !
Propose drills adaptations (size, player density, rules) to load/deload strength appropriately &/or top-ups
Monitoring neuromuscular responses following different training sessions
(Buchheit et al. 2018)
Optimizing Return to play
A case study | N. Mayer (S&C PSG)
“Principe of progressive overload”
VOLUME
INTENSITY
“Using players as a FLOATER is a simple means to decrease MechW load during SSGs, while preserving the specificity of team dynamics”
(Lacome et al. 2018)
MONITORING STRENGTH... IS IMPORTANT !
