The MD-4 Protocol (Strength & Power)
What is MD-4 in Soccer? MD-4 (Match Day minus 4) is the training session that occurs 4 days before a match. In Tactical Periodization, this is the Strength & Tension Day. The goal is to maximize neuromuscular power, acceleration, and braking forces. Unlike endurance days (MD-3), the duration of drills is short, but the intensity and explosive actions are maximal.
Stop Running Hills. Start Playing Football. The old school method for “Strength Day” was simple: run up a hill until you vomit, or spend 60 minutes in the gym lifting weights.
While gym work is vital for injury prevention, as modern coaches, we have a problem: We have limited time. If you only train 3 times a week, you cannot afford to waste a session without a ball at your feet.
This is where Integrated Strength Training comes in. We can achieve the same physiological load (breaking down muscle fibers to build power) while improving our tactical shape.
The Science of MD-4: “Tension”
On MD-4, we are not looking for high heart rates (like MD-3). We are looking for Muscular Tension.
- Area: Small Spaces.
- Numbers: Low (1v1, 2v2, 3v3).
- Duration: Short Reps (30-90 seconds).
- Rest: Long (to allow full ATP recovery).
- Contractions: Lots of accelerations, decelerations (braking), and changes of direction.
The Blueprint: A Perfect MD-4 Session
Here is how to structure a Strength/Power session entirely on the pitch.
Pre-Training Preparation (PTP)
The Warm-Up: Neuromuscular Activation (15 Mins)
On a Strength Day (MD-4), we do not just “jog” to warm up. We use a PTP (Performance Preparation) routine to potentate the nervous system before the ball rolls.
- Exercise A: Isometric Lunges (3 x 10 sec): Hold a deep lunge position. This wakes up the quads and glutes without causing fatigue.
- Exercise B: Pogos (2 x 10 reps): Stiff-legged jumps on the spot. We want to activate “ankle stiffness” for explosive ground contact.
- Exercise C: 1v1 Wrestling (2 mins): Pair players up to push shoulder-to-shoulder. This prepares the core and upper body for the physical contact of the session.

2. The Drill: “The Chaos Box” (2v2 + Finishers)
This is the ultimate MD-4 drill. It combines heavy braking loads (strength) with finishing.
Setup:
- Create a small 20x15m grid with a Goal on one end and two mini-goals on the other.
- The Rules: Play 2v2 inside the grid.
- The “Strength” Twist: The ball always starts with the coach feeding a bouncing ball or a hard pass. The intensity must be 100% from the first second.
- Duration: 45 seconds of work (Max effort).
- Rest: 90 seconds (Standing still).
- Reps: 6-8 reps per player.
Why this works: Because the space is small, players are constantly stopping and starting (Acceleration/Deceleration). This “Stop-Start” motion creates micro-tears in the muscle fibers—exactly what we want for building leg strength.
3. The Constraint-Led Approach: “The 18-Yard Lock”
To ensure the session remains a “Strength” day, we must manipulate the space constraints. If the pitch is too wide, players will run into open space (Endurance). We want them to collide and battle (Strength).
The Drill Setup:
Why this works: A narrow field eliminates “gliding” runs. It forces players into constant physical duels, shielding the ball, and explosive short turns.
Format: 5v5 + 2 Jokers.
The Constraint: The field is only the width of the 18-yard box but extends box-to-box length.
Principle Over Prescription: Adapting the Session
It is imperative to understand that the specific exercises detailed above—such as the PTP protocol and the “18-Yard Lock”—serve as selected examples to demonstrate the physiological constraints of MD-4. They are not rigid prescriptions.
The strength of the Morphocycle lies in its adaptability. As the coach, you retain full autonomy to design exercises that align with your specific Game Model and team context.
Whether you choose a 3v3, a positional rondo, or a different small-sided game, the drill is effective as long as it respects the day’s fundamental biological rules: high neuromuscular tension, frequent eccentric braking, and adequate recovery ratios.
Plan the drills that fit your players, but ensure the physical outcome remains non-negotiable.
Here we have an example of MD-4 Training Session at Borussia Dortmund:
Monitoring the Load
On MD-4, do not look at “Total Distance” on your GPS. That number should be low. Instead, look at “Accelerations >3m/s²” and “Decelerations <-3m/s²”. If those numbers are high, you have had a successful Strength Day.
Coach’s Tip: Since this session involves heavy muscular load, ensure your players perform a proper cool-down and prioritize protein intake immediately after training.

Frequently Asked Questions: MD-4 Soccer Strength
What is MD-4 in soccer training?
MD-4 stands for Match Day minus 4. In Tactical Periodization, this is the designated “Strength” or “Tension” day. The goal is to overload the neuromuscular system with explosive actions like accelerations, decelerations, and changes of direction in tight spaces.
Why use integrated training instead of the gym for strength?
While gym work is crucial for general strength, integrated training (using the ball on the pitch) allows coaches with limited time to develop football-specific power while simultaneously improving technical skills and tactical understanding.
What GPS metrics should I monitor on MD-4?
On a strength day, Total Distance should be relatively low. The key metrics to monitor are the number of high-intensity Accelerations (>3m/s²) and Decelerations (<-3m/s²), as these indicate high muscular load.
What is Eccentric Braking in football?
Eccentric braking is the ability of the muscle to lengthen under tension, specifically when stopping or changing direction. Training this on MD-4 is critical for injury prevention (ACL) and agility.
Can I do this session 2 days before a game?
No. MD-4 is a high-tension day that causes muscle damage. You need at least 72 hours to recover. Doing this on MD-2 (2 days before a game) will leave your players with “heavy legs” on match day.
