A study published in 2024 by Thomas P Craig and colleagues examining the physical progression of a professional Scottish soccer academy over a ten-year period caught my attention for reasons beyond the headline findings.
Published in the Open Access Journal of Sports Medicine, The Physical Progress of a Professional Scottish Soccer Academy Over a Ten-Year Period analysed physical testing data collected between 2006 and 2016 across academy age groups from U11 to U17.
The study found that players entering the academy later in the ten-year period were progressively:
- faster over 5m, 10m and 20m,
- more powerful,
- and capable of greater intermittent endurance outputs than comparable age-group players a decade earlier.
The annual improvements themselves were relatively modest numerically:
- approximately 0.0055 seconds per year over 5m,
- 0.008 seconds per year over 10m,
- and 0.011 seconds per year over 20m.
But perhaps that is precisely the point.
Modern elite football increasingly lives in marginal gains, repeated high-intensity actions and fractional advantages often decided over the first few metres.
In many ways, the findings mirror what we have already seen in the senior game.
Over the past two decades, elite football has become increasingly dependent on:
- acceleration,
- repeated sprint ability,
- transitional speed,
- recovery capacity,
- and the ability to execute technical actions under physical stress.
None of that is particularly surprising.
Importantly, however, the data within the study concludes in 2016.
And football has continued to evolve significantly since then.
Over the past decade alone, we have seen:
- increased pressing intensity,
- greater emphasis on transitional speed,
- wider use of GPS and locomotor monitoring,
- more integrated strength and conditioning programmes,
- specialist sprint coaching entering football environments,
- and growing focus on acceleration and deceleration mechanics.
If the academy physical profile was already shifting between 2006 and 2016, it is entirely possible those trends have accelerated even further since.
Which perhaps makes the underlying talent identification question even more relevant today than when the original data was collected.
If football is getting faster and more physically demanding… what exactly should academies be identifying at eight years old for entry into academies at U9?
Because that is where the real tension exists.
At U8 level:
- maturation is wildly uneven,
- physical development is unstable,
- speed is often temporary,
- and dominance can disappear almost overnight.
Yet academy systems increasingly make early decisions within environments that ultimately reward physical outputs.
Importantly, the study itself acknowledged the possibility that academies may consciously or subconsciously recruit towards taller, heavier and physically superior profiles.
That should probably make all of us pause for thought.
Because the modern academy pathway increasingly concentrates:
- coaching,
- contact time,
- sports science,
- strength and conditioning,
- nutrition,
- competition level,
- confidence,
- and belonging
inside the system from very early ages.
Which means the initial recruitment decision becomes disproportionately important.
And this is where I think movement interpretation matters enormously.
At pre-academy ages, I am not convinced we should primarily be asking:
“Who is the quickest?”
Instead, perhaps the better questions are:
- Who moves efficiently?
- Who adapts?
- Who coordinates?
- Who brakes well?
- Who reorganises their body quickly?
- Who solves movement problems?
- Who scans naturally?
- Who stays balanced under pressure?
- Who learns movement solutions rapidly?
But what do those things actually look like at pre-academy ages?
That is where the discussion becomes far more difficult.
Because many of these qualities are subtle.
And many are easily hidden behind early physical dominance.
For example, movement efficiency at eight years old may not look like explosive sprinting at all.
It may simply look like:
- a child rarely falling over,
- a player staying balanced while changing direction,
- smooth adjustments of stride length,
- the ability to decelerate without losing body control,
- or a player who seems to glide through crowded situations rather than crashing into them.
Adaptability may look like:
- changing movement solutions naturally,
- adjusting body shape quickly,
- reacting to awkward bounces,
- or finding new ways around pressure rather than repeating the same action every time.
Coordination may reveal itself in:
- how comfortably players rotate,
- shift weight,
- manipulate the ball while moving,
- or combine upper and lower body actions simultaneously.
Some children can run quickly in straight lines.
Far fewer can stay coordinated while scanning, turning, adjusting and executing football actions simultaneously.
Braking ability is another interesting one.
Some players can stop and reorganise instantly.
Others require several steps to regain balance before accelerating again.
At older ages this becomes associated with elite-level deceleration mechanics.
At younger ages, it may simply appear as:
- balance,
- control,
- body organisation,
- and fluidity.
And then there is scanning and perception.
Some children consistently appear “ahead” of the game despite not looking physically dominant.
Often this is because:
- they scan earlier,
- orient their body shape sooner,
- recognise space quicker,
- and move before others react.
Their efficiency begins cognitively rather than physically.
Which is why some players never appear explosive yet constantly arrive first.
The challenge is that many of these qualities are difficult to measure objectively.
They are often interpreted instinctively by coaches and scouts within extremely short observational windows.
That creates risk.
Because without a deeper understanding of movement, there is a danger that:
- physical dominance,
- early maturation,
- or aesthetic athleticism
becomes mistaken for long-term football potential.
And perhaps that is the biggest challenge facing modern academy recruitment.
The game absolutely requires better athletes than ever before.
But at eight years old, identifying future athletic and football potential is far more complex than simply identifying the child who currently wins the race.
The real challenge may not be identifying the fastest child today.
It may be identifying:
which child possesses the movement adaptability, coordination, efficiency and perceptual qualities that could eventually thrive in the faster game football is becoming.
