MONITORING STRENGTH ON THE FIELD

CONCEPTS & PRACTICAL APPLICATIONS

Striving for Excellence | 14.05.2018 | Lacome M.

  1. WHY measuring force application on the pitch matters ?

  2. HOW can we measure (estimate) force application ?

  3. WHAT can we practically DO with these models ?

Why IS IT IMPORTANT ?

Strength is KEY !

Horizontal alternation in specificity

“the three main training (acquisition) days in the week will alternate the physical fitness component.”

  3. WHAT can we practically DO with these models ?

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 !
