Analysis of Lower Hand Wrist Flexion and Twist of the Mallet Head in a Croquet Shot

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.

Background: High-speed drumming requires precise control over the timing, velocity, and magnitude of striking movements. Aim: To examine effects of tempo and expertise on unaccented repetitive drumming performance using 3D motion capture. Methods: Expert and amateur drummers performed unimanual, unaccented, repetitive drum strikes, using their dominant right hand, at five different tempi. Performance was examined with regard to timing variability, striking velocity variability, the ability to match the prescribed tempo, and additional variables. Results: Permutated multivariate analysis of variance (PERMANOVA) revealed significant main effects of tempo (p < .001) and expertise (p <.001) on timing variability and striking velocity variability; low timing variability and low striking velocity variability were associated with low/medium tempo as well as with increased expertise. Individually, improved precision appeared across an optimum tempo range. Precision was poorest at maximum tempo (400 hits per minute) for precision variables. Conclusions: Expert drummers demonstrated greater precision and consistency than amateurs. Findings indicate an optimum tempo range that extends with increased expertise.

AbstractRecent epidemiological analyses in fencing have shown that injuries and pain linked specifically to fencing training/competition were evident in 92.8% of fencers. Specifically the prevalence of Achilles tendon pathology has increased substantially in recent years, and males have been identified as being at greater risk of Achilles tendon injury compared to their female counterparts. This study aimed to examine gender differences in Achilles tendon loading during the fencing lunge.Achilles tendon load was obtained from eight male and eight female club level epee fencers using a 3D motion capture system and force platform information as they completed simulated lunges. Independent t-tests were performed on the data to determine whether differences existed.The results show that males were associated with significantly greater Achilles tendon loading rates in comparison to females.This suggests that male fencers may be at greater risk from Achilles tendon pathology as a function of fencing training/ competition.
