Soccer Training

Soccer is the world’s most popular sport, and it’s one of the most physically demanding.

The physical demands of soccer:

• Endurance — a 90-minute game with no timeouts, continuous movement
• Repeated sprint ability — 1,200+ changes in movement per game, including 30-40 sprints
• Acceleration — most sprints are 10-20m, not 60m
• Change of direction — cutting, pivoting, turning, stopping
• Aerobic capacity — the engine that supports everything else
• Explosive power — headers, shots, tackles, jumps
• Balance and coordination — dribbling, shielding the ball, staying on your feet

The numbers: a soccer player runs 10-13 km per game. About 8-12% of that is at high intensity. The engine matters more than in almost any other team sport.

The general rule: you can’t play soccer if you can’t run. Build the aerobic base first, then add speed, power, and skill.

The base: general strength in the weight room. Squat, deadlift, RDL, single-leg work. Everything else builds from there.

The four pillars:

1. Aerobic base

• 30-60 min LISS 3-4x per week off-season
• Long runs, tempo runs, cycling, rowing
• The foundation of everything — soccer is a running sport

2. Repeated sprint ability (RSA)

• 6-10x 20-30 sec hard / 30-60 sec easy
• Short sprints (10-20m) with full recovery
• Sport-specific: small-sided games, sprint-jog-sprint sequences
• 2-3 sessions per week off-season

3. Strength and power

• Back squat, deadlift, RDL — single-leg focus is critical
• Single-leg work (split squats, Bulgarian split squats, single-leg RDL)
• Power: power clean, box jumps, broad jumps
• 2-3 sessions per week off-season

4. Change of direction and agility

• Cutting drills (5-10-5 shuttle, pro-agility)
• Lateral movement drills
• Sport-specific: cone dribbling, 1v1 drills
• 2-3 sessions per week off-season

Sample off-season week:

Day	Session
Mon	Lower body + speed
Tue	Conditioning + core
Wed	Rest / mobility
Thu	Lower body + power
Fri	Conditioning + COD
Sat	Skill work / open play
Sun	Rest

Sample in-season week:

Day	Session
Mon	Full body (low volume)
Tue	Practice / game
Wed	Recovery + mobility
Thu	Full body (low volume)
Fri	Game
Sat	Game
Sun	Rest

In-season rule: 2 lifts per week, 45 min max. Practice provides the conditioning, speed, and COD work. Weight room is for maintenance and injury prevention.

The injury problem: soccer has a high rate of hamstring and ACL injuries. Nordic curls, single-leg work, and landing mechanics are non-negotiable.

Soccer is the most-studied sport in sports science. Here’s the research-consensus picture.

The energy system profile:

GPS studies on soccer matches (Stølen et al., 2005; Bangsbo et al., 2006; Bradley et al., 2009) show:

• Total distance: 10-13 km per game
• High-intensity running (>14.4 km/h): 2-3 km per game
• Sprinting (>25 km/h): 0.5-1 km per game
• Sprint count: 30-40 per game
• Average sprint distance: 10-20m
• Work-to-rest ratio: ~1:4 to 1:6

Soccer is aerobic-dominant with a significant anaerobic component. Aerobic capacity supports recovery between efforts; anaerobic capacity drives the sprints.

Physical determinants of performance:

• VO2max (aerobic capacity): 55-65 ml/kg/min in elite players. Correlates with distance covered.
• Repeated sprint ability (RSA): maintains sprint quality across the game.
• Sprint speed (10-30m): correlates with scoring chances and defensive recovery.
• Change of direction: correlates with dribbling, defending, positioning.
• Lower body strength: correlates with sprint speed and COD.
• Single-leg stability: correlates with injury prevention.

The injury profile:

Soccer has a high injury rate — especially in the lower body:

• Hamstring strains (~25%) — sprinting injuries, most common
• Ankle sprains (~20%) — cutting, landing
• Knee injuries (~15%, including ACL) — cutting, landing
• Groin strains (~10%) — kicking, cutting
• Calf strains (~10%) — sprinting

Evidence-based prevention:

• Nordic curls: 2-3x per week. Reduces hamstring injury ~50% (Petersen et al., 2011)
• FIFA 11+: 20-min neuromuscular warm-up. Reduces all injuries ~30-40%, ACL injuries ~50%
• Single-leg balance: 3x per week for ankle prevention
• Landing mechanics: plyometric progression
• Hip strengthening: side planks, Copenhagen planks, band work

Position-specific demands:

Position	Physical Demands
Goalkeeper	Reaction, explosive jumps, lateral movement
Center back	Aerial power, strength, moderate sprint
Fullback	Highest sprint distance, repeated sprints
Defensive mid	Endurance, positioning, moderate sprint
Central mid	Highest total distance, endurance-dominant
Attacking mid	Acceleration, change of direction
Winger	Highest sprint speed, repeated sprints
Striker	Acceleration, explosive power, aerial

Programming implications:

• Base lifts: back squat, deadlift, RDL, single-leg work
• Power: power clean, box jumps, broad jumps
• Conditioning: 3-4 sessions per week off-season, mostly aerobic with intervals
• Speed: 2-3 sessions per week off-season
• Injury prevention: every session (Nordics, single-leg, landing)
• In-season: 2x per week maintenance
• Deload every 6-8 weeks off-season, 4-6 weeks in-season

At the research level, soccer performance is a running-economy and injury-prevention problem with specific, measurable determinants.

The physical demands in detail:

Soccer GPS studies (Bradley et al., 2009; Di Salvo et al., 2007; Barros et al., 2007) quantify:

• Total distance: 10-13 km per 90-min game
• High-intensity distance (>14.4 km/h): 2-3 km
• Sprint distance (>25 km/h): 0.5-1 km
• Sprint count: 30-40 efforts
• Average sprint duration: 2-4 sec
• Average sprint distance: 10-20m
• Accelerations (>2 m/s²): 40-60 per game
• Decelerations: 30-50 per game

Positional differences (elite players):

Position	Total Distance	High-Intensity	Sprints
Center mid	11-13 km	Highest	High
Fullback	10-12 km	High	Highest
Winger	10-12 km	High	Highest
Striker	9-11 km	Moderate	High
Center back	9-11 km	Moderate	Low
Goalkeeper	4-5 km	Low	Minimal

Physical determinants of performance:

Aerobic:

• VO2max of 55-65 ml/kg/min in elite players
• Correlates with total distance covered
• Best trained with 4x4 min intervals at 90-95% max HR

Anaerobic:

• Repeated sprint ability (RSA) — the ability to maintain sprint speed across many efforts
• Correlates with high-intensity running late in the game
• Best trained with repeated sprint intervals (6-10x 20-30m with 20-30 sec rest)

Neuromuscular:

• 10-20m sprint speed
• Change of direction ability
• Reactive agility (response to opponent movement)
• Jump height (for headers, goalkeeper saves)

Injury prevention — the priority:

Soccer has one of the highest injury rates in sport. Evidence-based prevention (FIFA 11+, Petersen et al., 2011; Walden et al., 2012):

FIFA 11+ program:

• 20-min neuromuscular warm-up before every session
• Reduces all injuries by 30-40%
• Reduces ACL injuries by 50%
• Reduces hamstring injuries by 20-30%

Key components:

• Nordic hamstring curls (2-3x per week, reduces hamstring injury ~50%)
• Single-leg balance (3x per week)
• Landing mechanics training
• Lateral band walks
• Hip strengthening (Copenhagen planks, side planks)
• Core stability (planks, dead bugs)

Advanced programming models:

1. Polarized training (off-season):

• 80% of conditioning at low intensity (Zone 2)
• 20% at high intensity (intervals, sprints)
• Avoids the moderate-intensity dead zone

2. Block periodization:

• Block 1: aerobic base (4-5 weeks)
• Block 2: RSA and speed (3-4 weeks)
• Block 3: sport-specific prep (2-3 weeks)
• Block 4: in-season maintenance (weeks 1-2)

3. Concurrent model (in-season):

• 2 lifts per week, 45 min each
• Conditioning via practice
• Speed and COD via practice
• Weight room is for maintenance and injury prevention

The “small-sided games” alternative:

Many elite programs use small-sided games (SSG) for conditioning:

• 3v3, 4v4 on reduced pitch
• High-intensity, sport-specific
• Trains aerobic + anaerobic + skill simultaneously
• 2-3 sessions per week

SSG is often superior to running-based conditioning because it trains the specific movement patterns.

Testing benchmarks:

Test	High School	College	Elite
Yo-Yo IR1	16-18	18-20	20+
10m sprint	1.8-2.0 sec	1.7-1.85 sec	1.65-1.8 sec
30m sprint	4.3-4.6 sec	4.1-4.3 sec	3.9-4.1 sec
5-10-5 shuttle	4.5-4.9 sec	4.3-4.5 sec	4.1-4.3 sec
Vertical jump	20-24 in	24-28 in	28-32 in
Back squat 1RM	1.2-1.5x BW	1.5-1.8x BW	1.8-2.2x BW

Programming takeaways for advanced athletes:

• Train year-round; aerobic base in off-season, speed in pre-season
• 3-4 conditioning sessions per week in off-season
• 2-3 speed sessions per week in off-season
• Small-sided games for sport-specific conditioning
• Nordic curls 2-3x per week (non-negotiable)
• FIFA 11+ warm-up before every session
• In-season: 2x per week maintenance
• Test every 6-8 weeks, adjust based on transfer
• Sleep 8-9 hours — the biggest recovery lever
