Introduction
Two players have identical VO2max values of 60 ml/kg/min. By the 80th minute of a high-intensity match, one player is visibly fading while the other maintains pace. The difference is often running economy — the oxygen cost of running at a given speed. Running economy explains why two athletes with identical aerobic ceilings can have meaningfully different endurance performance, and why targeted training can improve a player’s effective aerobic capacity without necessarily raising their VO2max.

The Science
Running economy (RE) is defined as the steady-state oxygen consumption required to maintain a given running velocity. A player with good running economy uses less oxygen per kilometre covered — leaving more aerobic reserve for sprinting, jumping, and late-match intensity maintenance.
Determinants of running economy in football:
- Biomechanical efficiency: Ground contact time, stride length, vertical oscillation, and trunk posture all influence the metabolic cost of locomotion. Excessive vertical oscillation (bouncing) wastes energy on vertical displacement. Optimal stride length (neither overstride nor understride) minimises braking forces.
- Elastic energy storage and return: The Achilles tendon, plantar fascia, and patellar tendon store elastic energy during ground contact and release it during push-off. Stiffer, more elastic tendons return more of this stored energy — reducing the muscular work required per stride. Strength training increases tendon stiffness and improves elastic energy return.
- Metabolic adaptations: Muscle fibre composition, mitochondrial density, and capillary density all affect how efficiently oxygen is used at the cellular level. Higher Type I fibre proportions and greater mitochondrial volume improve substrate utilisation efficiency.
- Body composition: Excess fat mass increases the metabolic cost of running without increasing oxygen delivery capacity. Each 1 kg reduction in fat mass while maintaining lean mass improves running economy meaningfully.
- Heavy strength training improves running economy. Back squat, deadlift, and single-leg exercises at 80–90% 1RM, 2–3 times per week during pre-season, improve tendon stiffness and neuromuscular efficiency. Consistent 4–8% economy improvements over 8–12 weeks are documented.
- Plyometric training enhances elastic energy return. Depth jumps, bounding, and reactive jump-landing sequences specifically train the stretch-shortening cycle, improving the elastic energy storage and return properties of lower limb tendons.
- Optimise body composition for economy benefit. Reducing excess fat mass during pre-season directly improves running economy — each kg of fat eliminated reduces the metabolic cost of every km run during the season.
- Biomechanical feedback targets vertical oscillation. GPS devices that measure vertical oscillation allow identification of high-bounce runners. Specific cues (shorter steps, forward lean) reduce oscillation and directly improve economy metrics.
- Include acceleration quality work. Short acceleration drills (10–20m) with full recovery teach optimal mechanics for football-specific locomotion economy — more transferable than steady-state running economy interventions alone.
- Running economy is the oxygen cost per unit distance — a major determinant of endurance performance independent of VO2max
- Heavy strength training improves RE by 4–8% via increased tendon stiffness and neuromuscular efficiency
- Football-specific RE (during repeated acceleration/deceleration) is more relevant than treadmill steady-state measures
- VO2max training adaptations simultaneously improve running economy in most populations
- Body composition optimisation, plyometrics, and strength training all contribute to RE improvement

Football-specific running economy factors: Football involves constant acceleration and deceleration — the metabolic cost of repeated acceleration is substantially greater than constant-pace running. Players with better neuromuscular efficiency in acceleration mechanics (shorter ground contact, higher rate of force development) are more economical during football-specific locomotion than at constant-pace running.
What Research Says
Stølen et al. (2005) reviewed physiological demands of football in Sports Medicine, noting that elite players’ superior match-running performance compared to sub-elite is only partially explained by VO2max differences — running economy and anaerobic threshold position account for a significant additional component of on-pitch running capacity.
Helgerud et al. (2001) demonstrated in a landmark RCT in Medicine & Science in Sports & Exercise that interval training improving VO2max in football players also improved running economy by 6.7% over an 8-week training period — establishing that the same aerobic training adaptations that raise VO2max simultaneously improve economy.
Barnes and Kilding (2015) reviewed running economy determinants in Sports Medicine, identifying heavy strength training as a consistently effective strategy for improving running economy via tendon stiffness and neuromuscular efficiency improvements — with effect sizes of 2–8% economy improvement from 6–12 weeks of strength training added to endurance training.
Did You Know? GPS analysis of elite football matches reveals that players do not run at constant pace — they alternate between acceleration, deceleration, steady jog, and walking approximately every 4–6 seconds. The metabolic cost of this intermittent pattern is 20–30% higher than the cost of constant-pace running at the same average speed. This means football-specific running economy — economy during repeated acceleration/deceleration — is the more relevant measure than treadmill steady-state oxygen consumption.
