Nowadays, success in sports also depends crucially on the VE properties of the equipment used which should neither be too rigid nor too flexible. Some games are only possible due to the equipment’s VE behavior, and others are only attractive and tricky due to this. Sports goods, sports kit and sportswear etc. have become a paying playground for developers of VE composite materials.

Examples: The pole for pole vaulting; shoes when running and jumping (using “gel soles”); balls containing an air bubble or made of composite or solid material; the combination of the racket handle, racket strings, ball and net in tennis, squash, badminton, table tennis or ping-pong.
