The haptic perception affords detection of the physical and functional properties of an instrument actively sustained. Fifty-seven children (8.82 ± .38 years old) and sixty-four elderlies (71.3 ± 4.46 years old) estimated the length and the distance of the center of percussion for two Table Tennis rackets and a Badminton racket. The eigenvalues of each racket for length and distance from the wrist to the center of percussion were calculated. The present study confirmed the results obtained with Tennis Field rackets, extending them to Table Tennis and Badminton rackets, and, also, to children. The elderlies preserved, and children had the capacity of haptically detect physical and functional properties of Table Tennis and Badminton rackets. The weight of the rackets affected properties estimations. The eigenvalues may be a valid tool for the definition of physical and functional properties of sport instruments, allowing better adjustment to different motor development stages.
