How to Get Strikes in Bowling: Entry Angle Techniques

Downloads

Rod Ross and Kim Terrell-Kearney present examples of different styles and entry angles in this video. Having the ball at the correct entry angle as it enters the pins gives you a better chance of striking. If you want to increase your strike percentage, this video is for you!

    The very last thing said was, “You’re gonna need a little more deflection to get that carry.” What did you mean by deflection when compared to entry angle? Also, these tests were done with a ball entering the pocket rolling end over end. Have they done any tests with balls actually turning at different angles when entering the pockets?

      Hi Floyd. Study has shown that entering at six degrees in the roll phase is optimal. For application purposes six degrees isn’t always practical so deflection is needed to increase carry when the angles less than six degrees. There haven’t been studies with balls turning at different angles when entering the pocket but thanks for the suggestion.

    In the graphs shown in the video: 1. is offset the number of inches from the center of the lane (head pin) to the center of the ball when it first hit the pins? 2.What is the offset to the center of the 3 pin? 3. What is the read line shown near the bottom of the graph?

    so . . . do you know why you want to get the ball into a roll before it hits the pins?
    and how is carry % affected when your ball is only rolling 50% or 75% versus fully 100% rolling?

      You want the ball into a roll before hitting the pins because it offers the most force at impact. If the ball is still spinning one direction while traveling another it’s technically skidding and is less stable therefore more easily deflected when it hits the pins.

      Hi,

      The pin carry study provided interesting statistics regarding “the pocket” and how it’s defined. After speaking with engineers here at the United States Bowling Congress (USBC) you’re correct, the “offset” is from the center of the head pin to the center of the ball at contact.

      The head pin and three pin being 12 inches apart (center-to-center) would tell you how much offset there is from the three pin. Simply subtract the distance from the center of the head pin to get the offset of the three pin.

      The red plots on the bottom of the graph are shots that left 10 pins.

      Thanks for asking and for continuing with the Bowling Academy.

    Ticket#21452 I’m not sure it was part of this study, but does ball speed have any role in this?
