Understanding the Sport Depth System
Before we dive into the specifics of soccer training, let's first understand the framework we'll be using: the Sport Depth system. This training methodology groups similar sports to develop the required athletic abilities for peak performance. It focuses on four main areas of development:
- Explosiveness
- Strength
- Speed
- Endurance

The Sport Depth system helps athletes and coaches determine the ideal ratio of these elements for specific sports, ensuring targeted and effective training.
Soccer: A Continuous Go Sport
In the Sport Depth system, soccer falls under the category of "Continuous Go" sports, also known as Sport Depth 4. This category is characterized by:
- Constant movement
- Frequent changes of direction
- Alternating intensities
- Need for sustained energy throughout the match
Other sports in this category include field hockey, lacrosse, and basketball (for both guards and posts). These sports demand athletes who are lean, wiry, and possess an unrelenting engine, combined with relative strength and explosive, elastic movements.
The Ideal Training Ratio for Soccer
According to the Sport Depth system, the optimal training focus ratios for soccer and other Continuous Go sports are:
- Explosiveness: 25%
- Strength: 20%
- Speed: 35%
- Endurance: 20%
This breakdown gives us a starting point for designing a well-rounded training program for soccer players. Let's explore each of these components in detail and understand why they're crucial for soccer performance.
Speed: The Dominant Factor (35%)
It's no surprise that speed takes the largest share of the training focus for soccer players. In the fast-paced world of soccer, speed can be the difference between scoring a goal and missing an opportunity. But what exactly do we mean by "speed" in the context of soccer training?
Speed in soccer encompasses:
- Acceleration: The ability to quickly reach top speed from a standing start or change of direction.
- Top-end speed: The maximum velocity a player can achieve.
- Change of direction: The ability to decelerate, change direction, and accelerate again efficiently.

Why is speed so crucial in soccer? As the Sport Depth system explains, "Fast athletes are able to create opportunities that slower athletes are unable to perceive, let alone conceive." In soccer, this translates to:
- Beating defenders to the ball
- Making quick, decisive runs into space
- Rapidly transitioning from defense to attack
- Closing down opponents quickly when defending
Speed Training for Soccer Players
To develop speed effectively, soccer players should focus on:
- Sprinting technique: Proper form is essential for maximizing speed and reducing injury risk.
- Acceleration drills: Short sprints (10-30 yards) with emphasis on explosive starts.
- Top-end speed work: Longer sprints (40-60 yards) to develop maximum velocity.
- Change of direction drills: Incorporate quick turns, cuts, and direction changes.

Here's an example speed workout from the Sport Depth system that soccer players can adapt:
- Hill Sprints: 5 x 30 yards (2:30 rest between sets)
- 20 Yard Shuttle: 3 x 1 rep each direction (2:30 rest between sets)
- Sprints: 6 x 100m (3:00 rest between sets)
Remember, quality is key in speed training. Ensure full recovery between repetitions to maintain proper technique and maximum effort.
Explosiveness: The Game-Changer (25%)
While closely related to speed, explosiveness deserves its own focus in soccer training. The Sport Depth system defines explosiveness as "twitchy, elastic muscle qualities that make for quick movements that have a spring and a pop."

In soccer, explosiveness manifests in:
- Powerful jumps for headers
- Quick, forceful kicks
- Explosive first steps to beat defenders
- Rapid changes of direction
Explosiveness training aims to improve an athlete's ability to express a large amount of force in a short time. This is crucial in soccer, where split-second actions can decide the outcome of a match.
Explosiveness Training for Soccer Players
To develop explosiveness, soccer players should incorporate:
- Olympic lifts: Power cleans, snatches, and their variations
- Plyometrics: Box jumps, depth jumps, and bounding exercises
- Medicine ball throws: Rotational throws, chest passes, and overhead throws
- Strength exercises performed with speed intent: Fast squats, rapid push-ups
Here's a sample explosiveness workout based on the Sport Depth system:
- Box Power Snatch: 4 sets of 3 reps 2a. Front Squat: 4 sets of 3 reps 2b. Box Jumps: 4 sets of 5 reps 3a. Step-Up Jumps: 4 sets of 5 reps per leg 3b. Champion Strides: 4 sets of 4 reps per leg
- Sled Sprint: 5 x 20 yards
Explosiveness training should be performed when athletes are fresh, typically at the beginning of a workout after a thorough warm-up.
Strength: The Foundation (20%)
While soccer isn't typically associated with brute strength, a solid strength foundation is crucial for performance and injury prevention. The Sport Depth system emphasizes that "being strong will always be advantageous to athletes."

In soccer, strength contributes to:
- Shielding the ball from opponents
- Winning physical duels and tackles
- Generating power for shots and long passes
- Maintaining balance and stability during quick movements
- Reducing injury risk and improving recovery
Strength Training for Soccer Players
Soccer players should focus on developing overall body strength with an emphasis on lower body and core. Key exercises include:
- Squats (back squats, front squats, single-leg squats)
- Deadlifts
- Lunges and split squats
- Upper body pushing and pulling (bench press, rows, pull-ups)
- Core exercises (planks, ab rollouts, rotational movements)

Here's a sample strength workout based on the Sport Depth system:
- Clean: 3 sets of 3 reps, then 4 sets of 1 rep 2a. Unbroken Back Squat: 4 sets of 3 reps, then 1 set of 5 reps 2b. Depth Drop to Hurdle Hop: 5 sets of 2 reps 3a. Single Leg Squat: 3 sets of 7 reps per leg 3b. Glute Ham Raises: 3 sets of 12 reps 3c. Ab Roller: 3 sets of 12 reps
Remember, the goal for soccer players isn't to become powerlifters. Focus on building functional strength that translates to on-field performance.
Endurance: The Engine (20%)
Soccer matches last 90 minutes, often with additional time added. Players cover an average of 7-10 kilometers per game, with frequent sprints, direction changes, and varying intensities. Clearly, endurance is a crucial component of soccer fitness.

The Sport Depth system defines endurance as "the engine to maintain performance throughout the allotted time of competitive play and training at a high level tailored to sporting needs."
For soccer players, endurance contributes to:
- Maintaining high-intensity performance throughout the match
- Quick recovery between sprints and high-intensity actions
- Consistent technique and decision-making even when fatigued
- Reduced injury risk in the latter stages of matches
Endurance Training for Soccer Players
Soccer-specific endurance training should focus on:
- Aerobic capacity: Developing a strong cardiovascular base
- Anaerobic endurance: Improving the ability to perform repeated high-intensity efforts
- Soccer-specific conditioning: Combining endurance work with ball skills and game situations
Here's a sample endurance workout from the Sport Depth system that can be adapted for soccer:
Running: 6 x 800m at Zone 5 intensity (2:30 rest between sets)
Additionally, soccer players can incorporate:
- Fartlek training: Alternating between high and low intensities during a continuous run
- Small-sided games: Playing 3v3 or 4v4 matches with short rest periods
- Interval training: Mixing sprints with jogging recovery periods
Balancing the Training Components
Now that we've explored each component of the optimal training balance for soccer, the question remains: How do you put it all together into a cohesive training program?
Here are some guidelines to help you strike the right balance:
Prioritize quality over quantity: It's better to have shorter, high-quality sessions for each component than to try to cram everything into marathon training sessions.
Periodize your training: Vary the focus throughout the year. For example, you might emphasize strength and endurance in the off-season, then shift towards more speed and explosiveness work as the competitive season approaches.
Integrate components when possible: Many drills can develop multiple attributes simultaneously. For example, repeated sprint training improves both speed and endurance.

Listen to your body: The ideal balance may vary slightly from player to player. Pay attention to how you feel and perform, and adjust accordingly.
Don't neglect sport-specific skills: Remember, the Sport Depth system focuses on physical attributes. Make sure to allocate ample time for technical soccer skills and tactical understanding.
Consider position-specific needs: While the overall balance remains similar, a defender might need slightly more strength work, while a midfielder might benefit from additional endurance training.
Measuring Progress
To ensure your training is effective, it's crucial to regularly assess progress. The Sport Depth system recommends several primary testing exercises for Continuous Go sports like soccer:
- Vertical Jump (Explosiveness)
- 20 Yard Shuttle (Speed and Agility)
- 1 Mile Run (Endurance)
- Back Squat (Strength)
- Single Leg Squat (Strength and Balance)
- 40 Yard Dash (Speed)
Perform these tests periodically (e.g., every 6-8 weeks) to track improvements and identify areas that may need more focus.
The Bottom Line
Soccer demands a unique blend of physical attributes, and the optimal training balance reflects this complexity. By focusing on speed (35%), explosiveness (25%), strength (20%), and endurance (20%), soccer players can develop the well-rounded athleticism required for peak performance on the pitch.
Remember, these percentages are guidelines, not rigid rules. The key is to understand the principles behind each component and how they contribute to soccer performance. Experiment with the balance, listen to your body, and always keep the specifics of soccer in mind as you train.
By following this balanced approach, you'll develop the speed to beat defenders, the explosiveness to win crucial duels, the strength to maintain possession under pressure, and the endurance to perform at your best for the full 90 minutes and beyond.
Ultimately, the goal is to translate your physical development into on-field success. As you enhance your speed, explosiveness, strength, and endurance, you'll find yourself making quicker decisions, executing skills more precisely, and maintaining high-performance levels throughout the match.
So lace up your boots, hit the training ground, and embrace the challenge of optimizing your physical preparation for soccer. With dedication, smart training, and the right balance, you'll be well on your way to reaching your full potential on the soccer field.
