Bowler analysis in cricket using centre of mass inertial monitoring

Abstract

Bowling in cricket requires accuracy, repeatability, and speed control. Incorrect bowling action can result in poor performance and injury to the shoulder, lower back, and knee joints. In this paper, we present a wearable wireless technology suitable for everyday use by elite and recreational athletes alike. Wireless monitoring of front‐on bowler actions using inertial sensors placed in the centre of mass results in clear signals, which can be interpreted in terms of run‐up speed and length and hip rotation. For a bowler who was bowling submaximally, the run‐up speed was 2.7 m/s with a predelivery stride length of 1.2 m/s and a hip rotation of 401. This simple, inexpensive technique allows in‐field bowling assessment and analysis and promises to be a significant training aid.
