Abstract
The specification discloses a sports pole including at least two flexible rods, the first of which is held in compression and the second of which is held in tension by the spatial arrangement of the two rods relative to one another and relative to the handle. The tension rod is slidably connected to the handle at one end and fixedly connected to the compression rod at the other end. When the user plants the pole, the movement of the tension rod within the handle allows the compression rod to deflect further, thereby acting as an energy absorbing member. As the user advances through the pole stroke, the energy stored in the pole during planting and pushing is released as the compression rod returns to its original position. This yields a forward force applied to assist the user in forward motion.
