ABSTRACT:
A swimming paddle assembly has a long shaft with a rigid blade at each end. A pair of resilient flaps are attached to the leading edge of each blade, one on each side, so that as the swimmer pulls first on one side of the shaft and then the other side, one blade is pushed forward and the other is pulled back on a power stroke with the flaps open for greater resistance. On the return stroke the flaps are forced closed against the blade sides for reduced resistance. One or more vertical stabilizing panels attached to the lower limbs reduce side to side motion of the lower body. These may be on swim fins or mounted between the legs.
