Provided is an improved sports shaft that includes longitudinal channels running within the interior portion of the substantially hollow shaft. The channels, and more specifically, the channel walls that define the channels, provide additional strength to the sports shaft. The improved sports shaft is better suited to withstand impact forces over a longer period of time than a typical hollow shaft. The improved sports shaft also is also better suited to withstand the variety of non-impact forces that act upon a sports shaft during the course of play. A key advantage of the improved sports shaft is the dramatic increase in strength without the addition of unnecessary weight.
