Case Study: Piet’s Physical Transformation on the Elite Football Athlete Programme

When Piet joined the Matchfit Elite Football Athlete Programme, he was a talented young player from Germany competing at Under 11 level for a semi-professional club.

He primarily played as a winger and attacking midfielder, positions that demand speed, stamina, agility and confidence in one-on-one situations.

Piet already had some natural strengths in his game.

He described his biggest strengths as:

• Strong running ability

• Good natural conditioning

• Being a team player in both attack and defence

But both Piet and his family recognised something important.

If he wanted to give himself the best chance of progressing to a professional academy such as Werder Bremen, he needed to develop the physical side of his game.

At the time he joined the programme, Piet was a complete beginner to structured strength training.

His goals were clear.

He wanted to:

• Become faster and stronger

• Be more assertive in 1v1 situations

• Develop confidence in his technical ability

• Become a player that scouts couldn’t overlook

The Starting Point

Piet completed his first full athletic assessment in November 2024.

The testing measured key physical qualities required for football, including:

• Strength

• Speed

• Explosive power

• Change of direction ability

• Core stability

• Aerobic endurance

Like many young players who had never followed a structured strength and conditioning programme, most of Piet’s scores were around the average for his age group.

The movement screens also highlighted several areas that could be improved to help him become a stronger and more resilient athlete.

These included:

• Knee stability during squatting movements

• Limited ankle mobility

• Core stability and trunk control

• Hamstring flexibility

None of these issues were unusual for a 10-year-old footballer, but improving them would be important for both performance and injury prevention.

The Training Plan

Piet began following a structured football-specific strength and conditioning programme which we created for him to follow through our training app.

His training focused on developing the key physical qualities needed for football, including:

• Full body strength

• Acceleration and sprint speed

• Explosive power

• Change of direction ability

• Core strength and stability

• Football-specific stamina

Because Piet was still young and new to strength training, the early phases of training focused heavily on movement quality, technique and gradual progression.

But the biggest factor behind Piet’s progress was something simple.

Consistency.

Week after week, Piet completed his sessions and continued building his athletic foundation.

Piet’s Physical Development Results

Over the following months, Piet’s testing results showed clear improvements across multiple areas of performance.

Here are some of the key changes measured through objective testing.

🔥 Broad Jump (Explosive Power) 136 cm → 158.5 cm + 16.5% improvement

🔥 Press Ups (Upper Body Strength) 11 → 23 reps + 109% improvement

🔥 Wall Sit (Lower Body Strength & Endurance) 72 sec → 278 sec + 286% improvement

🔥 10m Sprint (Acceleration) 2.32 sec → 2.09 sec + 9.9% improvement

🔥 T-Test Agility (Change of Direction) 13.72 sec → 12.53 sec + 8.7% improvement

🔥 505 Change of Direction – Left 2.79 sec → 2.48 sec + 11.1% improvement

🔥 505 Change of Direction – Right 2.75 sec → 2.46 sec + 10.5% improvement

🔥 30m Flying Sprint (Top Speed) 5.10 sec → 4.53 sec + 11.2% improvement

🔥 Yo-Yo IRL2 Stamina Test 1240 m → 3040 m + 145% improvement

Why Some Percentage Improvements Appear Smaller

When looking at these results, it’s important to understand that not all physical qualities improve at the same rate.

Strength and muscular endurance tests, such as press ups or wall sits, can often improve very quickly when a player begins structured training.

This is why you sometimes see very large percentage increases in those tests.

Sprint and agility tests are different.

Because these tests are measured in seconds rather than repetitions, even small improvements can represent a very meaningful change in performance.

For example, improving a 10 metre sprint by just 0.2 seconds can make the difference between:

• Reaching the ball first

• Winning or losing a 1v1 race

• Creating space to attack

So while sprint improvements may show smaller percentage changes, they are often some of the most important improvements for football performance.

Improvements in Movement Quality

Alongside the physical testing results, Piet’s movement quality improved significantly during the programme.

Across multiple testing phases we saw:

• Better knee stability during squats

• Increased ankle mobility

• Improved balance and single-leg stability

• Much stronger core control

These changes help players move more efficiently on the pitch while also reducing injury risk as training intensity increases with age.

Confidence on the Pitch

One of the most important changes for Piet wasn’t just physical.

It was mental.

As his strength, speed and power improved, so did his confidence in matches.

He became more assertive when attacking defenders, more willing to take players on in 1v1 situations, and more confident using his technical skills.

For young players, this connection between physical development and confidence is extremely powerful.

When players feel stronger, faster and harder to stop, they naturally begin to play with more belief.

The Bigger Picture

When Piet joined the programme, his goal was simple.

He wanted to become the kind of player scouts couldn’t overlook.

Through structured training, consistent work and regular testing, he has already made huge progress towards that goal.

His strength, speed, agility and stamina have all improved significantly.

But perhaps most importantly, he has built the physical foundation needed to support his technical ability and long-term football ambitions.

And at just 10 years old when he started the programme, this is only the beginning of his development journey.

The Key Lesson

Piet’s progress shows what can happen when a talented young player combines technical ability with structured physical development.

Within just over a year he has:

• Doubled his upper body strength

• Dramatically improved lower body strength and endurance

• Become faster and more agile

• Built elite-level stamina for his age

Most importantly, he now has the physical confidence to express his football ability more fully on the pitch.

And that is exactly what the Elite Football Athlete Programme is designed to do.
