INTRODUCTION;

Running is one of the most natural human movements, yet it involves a complex interaction of muscles, joints, and forces. Understanding the biomechanics of running is crucial for injury prevention, performance enhancement, and faster recovery.

At Physio360 Chennai, we specialise in running gait analysis, sports physiotherapy, injury rehabilitation, and performance training to help runners achieve optimal efficiency.


WHAT IS RUNNING BIOMECHANICS?

Running biomechanics refers to the study of movement patterns, joint mechanics, muscle activation, and force distribution during running.

It involves:

✔ Joint motion (hip, knee, ankle)

✔ Muscle coordination

✔ Ground reaction forces

✔ Posture and alignment

✔ Energy efficiency

Proper biomechanics = Better performance + Lower injury risk


PHASES OF RUNNING GAIT CYCLE

Running is divided into two main phases:

1️⃣ STANCE PHASE (40%)

The foot is in contact with the ground

  • Initial contact (heel/midfoot/forefoot strike)

  • Mid-stance (body weight absorption)

  • Push-off (propulsion phase)

2️⃣ SWING PHASE (60%)

The foot is off the ground

  • Initial swing

  • Mid swing

  • Terminal swing (preparing for next step)

At Physio360 Centre in Chennai, advanced gait analysis helps identify abnormalities in each phase.


KEY BIOMECHANICAL COMPONENTS.


1. FOOT STRIKE PATTERN

  • Heel strike (rearfoot)

  • Midfoot strike

  • Forefoot strike

Improper strike → Increased risk of:

  • Shin splints

  • Plantar fasciitis

  • Stress fractures


2. CADENCE (STEP RATE)

  • Ideal: 160–180 steps/min

  • Low cadence → Overstriding → Higher impact forces

Increasing cadence reduces:

  • Knee stress

  • Hip loading


3. GROUND REACTION FORCE (GRF)

  • Force exerted by the ground during contact

  • Can be 2–3 times body weight

Poor biomechanics increases stress on:

  • Knee joint

  • Ankle joint

  • Lower back


4. POSTURE & ALIGNMENT

✔ Slight forward lean (from ankles)

✔ Neutral spine

✔ Relaxed shoulders

Poor posture leads to:

  • Low back pain

  • Neck stiffness

  • Reduced efficiency


5. JOINT KINEMATICS

Hip:

  • Extension for propulsion

  • Weak hip → IT band syndrome


Knee:

  • Shock absorption

  • Excess valgus → ACL risk


Ankle:

  • Energy transfer

  • Poor mobility → Achilles tendinitis


COMMON RUNNING INJURIES DUE TO POOR BIOMECHANICS

At Physio360 Sports Physiotherapy Clinic, we frequently treat:

Runner’s knee (Patellofemoral pain syndrome)

Shin splints (Medial tibial stress syndrome)

Achilles tendinitis

Plantar fasciitis

IT band syndrome

Stress fractures


Most injuries are due to:

  • Poor running mechanics

  • Muscle imbalance

  • Overtraining
