Learning Guide: Running Efficiency, Mechanics & Economy

What Is Running Economy?

Running economy is the amount of energy and oxygen required to maintain a given running pace. An efficient runner uses less energy to run at the same speed than an inefficient runner.

Think of it as:
• Better mechanics = lower energy cost
• Lower energy cost = faster running with less fatigue

Elite runners are not only aerobically fit — they are mechanically efficient.

The 5 Primary Influences on Running Economy

1. Neuromuscular Coordination - Neuromuscular coordination is how efficiently your brain and muscles communicate during running.

Efficient runners:
• Recruit the correct muscle fibers at the correct time
• Minimize unnecessary muscle activation
• Maintain smooth, rhythmic movement patterns

Why It Matters

Poor coordination creates:
• Excess tension
• Delayed force production
• Wasted movement
• Increased oxygen demand

Efficient coordination improves:
• Cadence
• Ground contact efficiency
• Relaxation at speed
• Stride rhythm

Key Concepts

Muscle Fiber Recruitment
• Type I fibers = endurance, fatigue resistant
• Type II fibers = power and force production

Efficient runners learn to:
• Use Type I fibers for steady aerobic work
• Recruit Type II fibers only when needed

How to Improve It

Drills
• A-Skips
• B-Skips
• High Knees
• Butt Kicks
• Bounding

Speed Reinforcement
• Strides (80–100m accelerations)
• Sprint drills
• Hill sprints

Strength Training
• Single-leg work
• Explosive movements
• Sport-specific coordination

2. Tendon & Muscle Stiffness - Running is essentially controlled bouncing. Your tendons store and release elastic energy every step.

The primary structures:
• Achilles tendon
• Plantar fascia
• Calves
• Hamstrings

Why Stiffness Matters

Optimal stiffness:
• Reduces energy leakage
• Improves recoil
• Shortens ground contact time
• Enhances propulsion

Too little stiffness:
• Excess sinking/collapse
• Longer contact times
• Energy loss

Too much stiffness:
• Reduced shock absorption
• Higher injury risk

Goal - Develop elastic stiffness, not rigid tension.

You want:
• Spring-like mechanics
• Quick rebound
• Stable landing

How to Improve It

Plyometrics
• Pogos
• Jump rope
• Bounds
• Hops
• Box jumps

Strength Training
• Calf raises
• Heavy split squats
• Romanian deadlifts
• Single-leg stability work

Running Cues
• “Get off the ground quickly”
• “Light and quick”
• “Run tall”

3. Stride Mechanics - Efficient stride mechanics minimize braking forces while maximizing forward propulsion. This is one of the largest determinants of running economy.

Proper Foot Strike

Key Principle

Your foot should land:
• Under your body
• Under your center of mass
• Not out in front

Ideal Position
• Vertical shin at contact
• Bent knee
• Midfoot landing

Why Overstriding Is Inefficient

Overstriding causes:
• Heel striking
• Braking forces
• Increased loading
• Longer ground contact time
• Higher oxygen cost

The farther your foot lands in front of you, the more you “put on the brakes” every step.

Efficient Landing

Aim for:
• Soft contact
• Midfoot strike
• Quick transition off the ground

Think: “Pull the ground behind you.”

Cadence = steps per minute.

Target Range - Most efficient runners: 170–180+ steps/minute

High cadence helps:
• Reduce overstriding
• Improve rhythm
• Lower impact forces
• Shorten contact time

Important - Do NOT artificially force cadence overnight.

Increase gradually through:
• Strides
• Metronome runs
• Shortened stride length
• Faster leg turnover drills

Key Cue “Shorter, quicker, lighter steps.”

Ground Contact Time

Efficient runners:
• Spend minimal time on the ground
• Produce force rapidly
• Maintain forward momentum

Goal:
• Quick contact
• Strong push-off
• Minimal vertical oscillation

Avoid:
• Sitting into the stride
• Excess bouncing
• Heavy foot strikes

4. Core, Glute & Hip Stability - Running economy deteriorates rapidly when stability breaks down.

This becomes especially important:
• Late in long runs
• Under fatigue
• After cycling in triathlon
• During hills

What Happens with Weak Stability

Weak stabilizers cause:
• Pelvis collapse
• Hip drop
• Side-to-side movement
• Rotational energy loss

All of this wastes energy.

Primary Stabilizers

Core
Maintains:
• Posture
• Rib-pelvis alignment
• Force transfer

Glutes - Primary propulsion muscles.
Especially:
• Glute max = extension power
• Glute med = pelvic stability

Hips
Control:
• Knee alignment
• Stride tracking
• Single-leg balance

Strength Priorities
Core
• Dead bugs
• Planks
• Pallof press
• Carries

Glutes
• Hip thrusts
• Split squats
• Single-leg RDLs
• Step-ups

Stability
• Lateral band walks
• Copenhagen planks
• Single-leg balance work

5. Body Composition - Running economy improves when excess body mass is reduced.

Less mass:
• Requires less energy per stride
• Reduces impact forces
• Improves relative power

Important Balance - The goal is NOT simply “lighter.”

You need:
• Enough lean mass for force production
• Enough strength for durability
• Enough fuel availability for recovery

Over-restricting calories can:
• Reduce performance
• Increase injury risk
• Decrease power production

Efficient runners are:
• Lean
• Strong
• Durable

Running Form Fundamentals

Posture - Run Tall
Efficient posture begins with alignment.

Focus On
• Upright torso
• Slight forward lean from ankles
• Neutral spine
• Relaxed upper body

Avoid
• Bending at waist
• Sitting backward
• Slouching

Key Cue - “Tall posture with a slight forward lean.”

Head Position - Your gaze controls alignment.

Proper Position
• Look ahead
• Chin neutral
• Neck relaxed

Avoid
• Looking down constantly
• Chin jutting forward

Shoulder Position - Tension wastes energy.

Goal
• Relaxed shoulders
• Down and back
• Loose hands
• Relaxed jaw
Key Cue - “Relax everything not needed for running.”

Arm Mechanics - Arms help control rhythm and balance.

Efficient Arm Swing
• Elbows ~90°
• Swing front to back
• Stay close to body
• Hands relaxed

Avoid
• Crossing arms across midline
• Tight fists
• Elevated shoulders

Why It Matters
Excess side-to-side arm motion:
• Rotates torso
• Wastes energy
• Disrupts stride efficiency

Compact Efficient Stride
The ideal stride is:
• Compact
• Circular
• Elastic
• Quick

Efficient runners:
• Pull through quickly
• Land softly
• Maintain rhythm
• Avoid reaching forward
