Training equipment includes a hollow shaft having a sidewall defining an internal cavity and at least one polymer material filling at least a portion of the internal cavity. The polymer material may fill the entire internal cavity of the hollow shaft. The polymer material may be a visco-elastic polymer material or polyurethane. A spacer or a filler may fill at least a portion of the internal cavity. A method of making weighted training equipment with a hollow shaft having a sidewall defining an internal cavity may include injecting a curable composition into at least a portion of the internal cavity. The method may further include curing the curable composition into a polymer material.

A sports racquet attachment includes a shaped body for attachment to a portion of a racquet. The ball retrieval racquet attachment has a pick-up cup at an end of the ball retrieval racquet attachment and a butt cap opening at another end of the ball retrieval racquet attachment. The pick-up cap has at least one ball finger interior to the pick-up cup. The butt cap opening has at least one butt cap stopper interior to the butt cap.

A transducer attenuates a physiologically damaging vibration by converting vibration energy to fluidization energy. The transducer includes a canister defining a sealed enclosure, a powder contained within the enclosure, and a coupler for vibrationally coupling the canister to the physiologically damaging vibration. When undisturbed, the powder has a settled state occupying less than the entire enclosure of the canister. However, when excited by physiologically damaging vibration, the powder has a fluidized state occupying the entire enclosure of the canister. When agitated by the physiologically damaging vibration via the coupler, the canister transmits vibration energy to the powder contained therein and causes the powder to fluidize, thereby attenuating the physiologically damaging vibration.
