The Sweet Spot in Racket or Bat Sports

Описание: Understanding the effects of impact location (sweet spot) in racket or bat sports. What does research say about the badminton smash, cricket power hitting, and historical racket development in tennis?

This video presents an overview of the scientific research (including my own) on the relationships between impact location and performance outcomes (speed, direction, and margin for error) or injury risk factors in racket and bat sports. This includes theoretical definitions of the sweet spot such as the geometric center, vibration node, center of percussion, and maximum apparent coefficient of restitution. Likewise, studies including realistic performances by elite badminton or cricket players are used to show the interactions between athletes and their equipment. Novel methods are applied to track the ball or shuttle and calculate impact location / sweetspot on the bat face or racket face. #ScienceOfCricket
