ALT Contribute to the Understanding of Historical Racket Development In a collaboration between researchers at Manchester Metropolitan University, Loughborough University, and the University of Suffolk - funded by the International Sports Engineering Association - we are asking for your help in studying the historical development of sporting rackets. If you have access to one or more rackets (old or new) from any sport - or know anybody who has - we would appreciate you taking the time to submit some photographs and basic measurements. We will provide participants with summary results and graphs at a later date, showing the development of rackets over time and allowing you to compare your racket(s) against others. This is expected to take 10-15 minutes in total.
