Analysis of lower hand wrist flexion and twist of the mallet head in a croquet shot

Abstract

This study investigated the relationship between wrist flexion and the dynamics of the swing of a croquet mallet. Twenty-seven subjects participated in a study which used 3D motion capture equipment along with high-speed and high-definition video to determine if there is a correlation between the lateral twist of a croquet player's swing and the flexion of the wrist during that swing. The study found a significant correlation between the amount of flexion of the wrist from the start of the stroke to the top of the backswing and the twist of the mallet head at the top of the backswing (r = 0.330; p < 0.01). The methodology and findings are relevant to all sports where minimising wrist flexion is favourable for improving the consistency of stroke-making (e.g., golf putting, darts and snooker). Additionally, reducing wrist motion in stroke-making may reduce the incidence of wrist pain and injury in croquet. This second point provides further encouragement for attempting to reduce the amount of wrist flexion during croquet swings.
