Kinetic Chain

Analyse proximal-to-distal sequencing in throwing, kicking, and striking movements. Plot peak angular velocity timing across the chain to assess efficiency of energy transfer.

📊 Sample baseball throw
The proximal-to-distal principle: In skilled throwing and kicking, proximal segments (pelvis, trunk) peak first then decelerate, transferring energy to successively faster distal segments. Each distal segment should peak later than its proximal neighbour, and angular velocity should generally increase moving distally. Disruption of this sequence indicates inefficiency or injury compensation.
