Part 2 — Brains Mature Later Than We Once Thought

01

The Brain Is Still Maturing After the Age of 20

What late maturation means on the football pitch

Research over the past decades has shown that brain development continues much longer than we once assumed — throughout adolescence and into early adulthood. Different systems develop at different speeds. Some mature relatively early. Others, especially those related to planning, impulse control, weighing consequences, emotional regulation, self-evaluation, and long-term decision-making, continue to develop well into adolescence and beyond the age of 20.

"Football asks a player to scan, recognise cues, regulate emotion under pressure, and connect her action to the wider team intention. These rely on systems still maturing well into her twenties."

Football does not only ask a player to execute technical actions such as receiving, passing, dribbling, or 1v1 actions. It asks her to do this in the constantly changing context of the game. She must scan, recognise cues, interpret what the moment demands, anticipate teammates and opponents, regulate emotion under pressure, recover from mistakes, and connect her action to the wider team intention.

These are not simple demands. They rely heavily on systems of the brain that are still maturing throughout the teenage years and often into early adulthood. That means a talented young female player may still be developing in areas such as:

Scanning consistently and early

Shifting attention between cues

Making fast decisions under pressure

Regulating frustration after mistakes

Processing feedback in the moment

Staying clear-minded after disappointment

Linking a coach's message to action in the game

These should not be seen as signs of lower quality or lower potential. They are a normal part of development. If coaches, scouts, or clubs do not understand this, they risk misreading normal developmental variability as a lack of football intelligence, mentality, discipline, or potential. In the women's game, where pathways are still narrower and second chances are often fewer, that kind of misreading can be especially costly.

02

Puberty and Brain Development Happen at the Same Time and Interact

Why the picture becomes more complex in the women's game

In football, brain maturation cannot be separated from puberty. Puberty in girls generally begins earlier than in boys, but its timing and impact vary enormously from player to player. Some female players begin this process very early. Others much later. This means that within one age group, players of the same chronological age can be in very different biological, emotional, and neurological stages of development — and yet they are often coached, compared, and selected as if they are equivalent.

That is where many misunderstandings begin.

During puberty, hormonal shifts influence far more than the body alone. They can affect mood, energy, emotional regulation, concentration, body awareness, and how a player experiences herself from week to week. At the same time, the brain systems needed to organise, regulate, interpret, and adapt are still developing. The body is changing, the brain is changing, and the player's sense of self is changing — all at once.

A young female player who at U12 looked technically composed, agile, and confident on the ball...

...may look very different at U14.

That does not mean she has gone backwards. It may mean she is moving through a complex developmental window in which body, brain, identity, and confidence are all in transition.

Growth spurts can temporarily disrupt timing, balance, coordination, and movement efficiency. Changes in body shape or composition can alter how a player experiences speed, contact, turning, jumping, or striking the ball. At the same time, increased self-consciousness can affect how freely she expresses herself in the game. These changes are real. They are normal. And they are often poorly understood in football environments.

Variability during puberty is not a signal of low potential. It is often a signal of development in progress.

03

The Prefrontal Cortex Needs to Be Challenged and Supported Over Time

The brain region at the heart of football learning

A key part of this conversation is the prefrontal cortex — the area of the brain that plays a major role in planning, thinking ahead, impulse control, evaluating decisions, understanding consequences, emotional regulation, and adapting behaviour. In football language, it is active when a player reflects on a decision, adapts her behaviour after a mistake, manages frustration, stays composed under pressure, interprets feedback, and links game experience to future action.

The prefrontal cortex does not mature quickly. It develops gradually over many years and needs repeated experience, appropriate challenge, guidance, and support from the environment to strengthen over time.

Brain Development Is Like Building a House

You do not begin with the roof. You build the foundation first, then upward. Each new layer depends on the strength of what sits below it. A young female player still building foundational layers — body confidence, emotional stability, self-regulation — is not behind. She is building.

A fast finish on a weak foundation rarely holds. A slower build on stronger ground often lasts.

A young female player who feels safe, trusted, and supported is more likely to remain cognitively open. She is more likely to try again, take initiative, stay engaged after mistakes, and continue to search for solutions. A player who feels watched, judged, or uncertain can narrow. Her decision-making may become safer. Her scanning may reduce. Her willingness to try may disappear.

This is why confidence and development are connected — they are not separate threads.

04

Confidence and Fear of Failure Are Not Just Personality Issues

Reading developmental responses more accurately

One of the biggest mistakes in talent development is to treat confidence, hesitation, or fear of failure as if they are simply personality traits. Often they are not. What looks like a lack of courage or mentality may actually be a developmental and neurological response to the environment.

When a young female player is afraid of making mistakes, or senses that her role or coach's trust depends on looking right rather than learning, the brain shifts into protection mode. Attention narrows. Initiative drops. Risk-taking decreases. The player becomes more careful, more reactive, and less expressive. From the outside, this may look like passivity, low intensity, poor body language, or reduced competitive drive — but often it is the behaviour of a player who is trying not to get hurt by the environment.

This matters especially in women's football because many female players arrive in performance environments already shaped by broader social messages: do not be wrong, do not stand out too much, do not take up too much space.

Before deciding that a player lacks bravery or mentality, a better question is: What has the environment taught her is safe?

?

Has she truly been given room to try, fail, reflect, and try again?

?

Or has she learned that visibility is risky and safety is rewarded?

That is not a small question. It sits at the centre of female player development.

05

Young Female Players May Look Mature Before They Are Fully Ready

The gap between surface maturity and underlying capacity

A further implication of later brain development is that many adolescent female players are still not fully equipped to independently manage all the demands placed on them.

They may communicate well and say the right things in a review meeting.

They may look organised from the outside.

But that does not always mean the underlying capacities are fully developed.

Planning ahead, managing competing demands, regulating emotion under pressure, understanding long-term consequences, and genuinely reflecting on one's own development are all sophisticated functions. These capacities are still being built. When adults expect a 14-, 15-, or 16-year-old female player to fully self-manage her development and process feedback with adult depth, they may be asking for something developmentally premature.

"That is not empowering. It is often too much, too early."

Young female players still need structure, guidance, consistent language, support in reflection, and help making sense of their experiences. The goal is gradual ownership. The coach's role is not to do the thinking for the player forever. It is to walk alongside her while those capacities are still being built.

06

Evaluation Conversations with Female Players Need More Depth

Slower, more curious, and more relational conversations

A player may give thoughtful or composed answers in a review conversation — she may know the "correct" response and sound reflective. But the depth of genuine self-understanding behind those words can vary enormously at this age. Many female players are socially attuned and good at reading adults. They may tell the coach what they think the coach wants to hear. That should not be mistaken for deep reflection.

Better conversations are slower, more curious, and more relational. They ask:

?

What did you really experience there?

?

What felt difficult?

?

What changed for you in that phase?

?

What did you notice in yourself?

?

What do you think helped you?

?

What do you still not fully understand yet?

Those kinds of conversations support real learning. And real learning, over time, supports more self-aware and resilient players.

What Coaches and Clubs Can Do

Practical implications of understanding brain development

If brain development continues longer than we once thought, and if puberty, confidence, identity, and environment all interact with learning, then coaching cannot only be about instruction and correction. It must also be about timing, understanding, and environment.

◆ For Coaches

Recognise that inconsistency during adolescence is often developmental, not motivational
Do not confuse temporary coordination changes or hesitation with declining potential
Use clear, repeated, age-appropriate language — don't assume understanding after one explanation
Guide decision-making and reflection over time, not just in one session
Create psychologically safe environments where mistakes are part of learning
Reduce fear-based coaching and constant judgment
Help players understand the game in layers rather than overloading them
See emotional responses as part of development, not simply as attitude issues

◆ For Clubs

Educate coaches in female development, adolescence, learning, and the body-brain-environment interaction
Build age-group philosophies that reflect developmental reality rather than only short-term performance pressure
Avoid selection cultures that over-reward early stability and under-value players in transition
Create spaces where reflection, communication, and trust are part of the development process
Recognise puberty as a major developmental phase affecting performance and behaviour
Involve parents in understanding what female players may be going through
Ensure the player's personal growth is not separated from her football growth

Good coaching in this phase is not softer coaching. It is more intentional, more informed, and more accurate coaching.
