Quick Tip: Axis Rotation Practice

Duration:   1  mins

Description

Axis rotation is how much side rotation your bowling ball has while rolling down the lane. In this quick tip Coach Erik Vermilyea of Track demonstrates how to achieve more and less axis rotation by practicing with a soft ball or football.

Minimal axis rotation happens when the bowling ball rolls more end-over-end, closest to 0º.

AR1

Maximum axis rotation is the most side rotation you can put on the bowling ball getting as close to 90º as possible.

AR2

Medium axis rotation is in the middle with 45º of rotation, average side rotation.

AR3

Before starting this drill you’ll need to know what your normal axis rotation is. The goal is to determine a hand position that achieves more and less axis rotation to manipulate ball roll in order to stay in the pocket.

Minimal Axis Rotation

Less hook gets the job done, sometimes. In order to make the bowling ball hook less, you’ll want to make the bowling ball roll more end over end. Start by putting the softball in the palm of your hand and release the ball with your hand up the back of it.

AR4

Maximum Axis Rotation

Having more side rotation than your “normal” release helps hook the ball more. To make this happen, hold the ball all the way to the side and release. This will get your bowling balls axis rotation as close to 90º as possible.

AR5

Medium Axis Rotation

This is considered to be a normal/typical release that enables the bowling ball to roll close to 45º of axis rotation. Your hand position is in between the previous two releases.

AR6

Practicing with a football or softball off the lanes is a great way to train yourself to adjust your release. Too often bowlers go to their bag for a ball change, while making an adjustment with your hand will keep you in the pocket, striking.

Hi there, welcome to National Bowling Academy. I'm Erik Vermilyea and today I've got a quick tip for you regarding axis rotation. And more importantly, what it is and how to practice it. So axis rotation in a nutshell is simply how much side rotation your bowling ball has. Now if it's a more, end over end direct one, for a minimal axis rotation, we'll call that right around zero degrees with rotation. On the opposite side, maximum axis rotation will be 90 degrees, a lot of side rotations You can kind of picture Pete Weber throwing the bowling ball, the king of axis rotation. And then kind of right in the middle is about a 45 degree average amount of side rotation. Easy way to practice it for you. It's important to kind of know A, what your normal axis rotation is, and then be able to have a release that's a little bit less axis rotation and then one that's a little bit more axis rotation. This'll give you more tools to work with when you're bowling tournaments, but a little bit different on league night. Give you a few more options to still line up and throw strike. Really easy way to practice this. Is to either grab a softball or a football, simply hold them in your hands and practice throwing a few shots. It's kind of up in the air yourself with a zero, a 45 or a 90, and get a feel for what the different rotations would look like. Again, same thing, just kind of up the back of it end over end will be zero all the way on the sides 90 kind of right in the middle is a 45 degree. This is a real easy way for you to take stuff you might have laying around the house and be able to just kind of look at it and understand that, you know, maybe my normal release looks right around here. Here's how I would create a little bit more end over end rotation. Here's how I create a little bit more side rotation and then go on the land to practice it. Throw a few normal shots. Try to throw a few more end over end up the back, a few more further around the side of it. See what kind of different ball reactions you can create. Take it to the lanes and knock down some more pins.
