INTRODUCTION;
Throwing is one of the most complex and high-velocity movements in sports. Whether it is cricket, baseball, javelin, handball, or throwball, efficient throwing mechanics require perfect coordination of the shoulder, elbow, wrist, spine, hips, and lower limb muscles. At Physio360 Chennai, we specialise in analysing and correcting throwing biomechanics to prevent injuries and enhance performance.
If you are searching for the best sports physiotherapy near me, shoulder pain treatment, or throwing injury rehabilitation in Chennai, this guide will help you understand the science behind throwing and how Physio360 Sports Centre supports athletes for fast recovery and peak performance.
What is Biomechanics of Throwing?
Biomechanics is the study of movement and the forces acting on the body. In throwing, it involves:
✔ Joint angles
✔ Muscle activation sequence
✔ Force generation
✔ Energy transfer from lower limb to upper limb
✔ Kinetic chain efficiency
Throwing is not just an arm action — it is a full-body kinetic chain movement.
Phases of Throwing Motion
Throwing can be divided into six major phases:
Wind-Up Phase
Purpose: Preparation and balance
Minimal shoulder stress
Body weight shifts to the back leg
Core muscles engage for stability
Scapular muscles activate
Poor balance during this stage increases stress in later phases.
Early Cocking (Stride Phase)
Purpose: Generate momentum
Stride foot moves forward
Trunk begins rotation
Shoulder abducts and externally rotates
Scapula retracts
Key muscles: deltoid, rotator cuff, and serratus anterior
Improper stride length can reduce velocity and cause shoulder impingement.
Late Cocking Phase
Purpose: Maximal energy storage
Shoulder reaches maximum external rotation (up to 170–180°)
Elbow flexed at ~90°
High stress on the anterior shoulder capsule
⚠ This is the most injury-prone phase.
Common injuries:
✔ Rotator cuff tendinitis
✔ Labral tears
✔ Shoulder instability
At Physio360 Centre in Chennai, we assess scapular dyskinesis and capsular tightness to prevent such injuries.
Acceleration Phase
Purpose: Maximum velocity generation
Rapid internal rotation of the shoulder
Elbow extension velocity peaks
Wrist flexion contributes to ball speed
Shoulder internal rotation speed can reach 7000° per second in elite throwers.
This phase demands:
Strong core
Stable scapula
Proper hip rotation
Deceleration Phase
Purpose: Safely slow down the arm
Posterior shoulder muscles absorb force
High eccentric load on the rotator cuff
Risk of posterior shoulder strain
Most muscular injuries occur here due to overload.
Follow-Through Phase
Purpose: Dissipate remaining energy
The body moves forward
Trunk flexion increases
The lower limb stabilises movement
Poor follow-through increases elbow stress (increased risk of UCL injury).

The Kinetic Chain Concept
Throwing power starts from:
🦵 Legs → 🦴 Hips → 🧠 Core → 💪 Shoulder → 🖐 Wrist
If one link fails:
Shoulder overload increases
Elbow injuries occur
Performance drops
At Physio360 Sports Centre Chennai, we focus on whole-body rehabilitation, not just shoulder treatment.
Common Throwing Injuries
✔ Rotator cuff tendinitis
✔ SLAP lesions
✔ Shoulder impingement syndrome
✔ Medial elbow stress injury
✔ UCL sprain
✔ Scapular dyskinesis
