Ten-pin bowling the body in step one; step two has the ball at the bottom of the backswing; in step three, the ball is at the top of the backswing; finally, the ball is swung forward and delivered in conjunction with the fourth and final slide-step. In a five-step approach, the bowler takes an initial timing step before pushing the ball away from the body. The regulations listed here are generally based around regulations set by the United States Bowling Congress — based on the original rules first codified by a USBC predecessor, the American Bowling Congress in 1895 — and the
Ten-pin bowling influence lane conditions and scoring. Establishing a Bowling Ball Specifications Task Force—comprising research engineers and volunteers from ball manufacturing companies—the USBC sought to better understand the motion of bowling balls using scientific research and data analysis. Test equipment included, but was not limited to, a robotic ball-thrower, a Computer Aided Tracking System ("Super C.A.T.S."), 59 reactive resin and particle bowling balls from various manufacturers, and eight lanes in a climate-controlled facility. The driving force behind the study was summed up by USBC Technical Director Neil Stremmel: "USBC is concerned that technology has overtaken player skill [as the primary factor] in
