In fast movements like throwing or kicking, the sequence goes big to small: hips rotate first, then shoulders, then arm, then wrist. Each segment stacks momentum onto the next. Drag the slider to fire segments in sequence.
In throwing, the kinetic chain begins with hip rotation generating torque in the transverse plane. This angular momentum transfers to the torso, which adds frontal plane flexion and further rotation. The shoulder joint then accelerates the upper arm using the deltoids and rotator cuff muscles. Finally, elbow extension and wrist snap add the terminal velocity. Each segment contributes roughly 20-30% additional velocity, compounding to create release speeds exceeding 40 m/s in elite cricket fast bowlers. The principle is universal: larger, slower-moving proximal segments create a foundation for smaller, faster distal segments.
Summation of momentum sequences body segments from large to small, with each link in the chain adding velocity to maximise speed at release or impact.
