We analyze in depth the biomechanical characteristics of New Zealand bowler Ish Sodhi. His arm action, with an elbow angle close to 180 degrees, generates a unique spinning effect in the air. The rotation of the shoulder and wrist, synchronized in a whip-like motion, are the key to his ability to deviate the ball's trajectory unpredictably.
The physics behind the spin: analysis of the wrist and elbow 🌀
A 3D model reveals that Sodhi releases the ball with a rotational speed of up to 2500 rpm. The pronation of his forearm, combined with extreme wrist flexion, allows the index finger and thumb to act as a gear. This mechanism, similar to a slingshot, transfers kinetic energy from the torso to the ball, generating lateral movement that confuses batters. The analysis shows that his release point is consistently low, close to the ground.
The mystery of the arm that bends twice 🤯
According to the 3D model, Sodhi's arm seems to have a phantom joint. Sometimes, his elbow bends at an angle that defies human anatomy, making the ball appear to come from a parallel dimension. Batters, watching the slow-motion replay, can only scratch their heads. Some technicians suggest it's a magic trick; others, that Sodhi has a spring in his shoulder.
