The Unknown Truth about Learning Golf and Motivation with Dr. Gabriele Wulf and Dr. Rebecca Lewthwaite

There are two critical factors in motivational learning that most people ignore. We’re going to address these two factors in today’s episode of Golf Science Lab.

We’re talking with two experts in the field of motor learning, Dr. Gabriele Wulf and Dr. Rebecca Lewthwaite. Both have extensive experience in this topic and have written some of the papers that have defined the field of motivational learning. You’re not going to want to miss this!

Make Golf Feel Easy (Constraint Based Learning) with Graeme McDowall & Peter Arnott

What if tournaments and potentially “stressful” rounds of golf suddenly seemed easy? Well that’s what we’re going to talk about today with a constraint-based approach to coaching and learning.

The general tenant we’re going to talk about with Peter Arnott and Graeme McDowall is that your solution to problems are different from anyone else’s, so let the individual find a way that is fit for them to solve that problem instead of putting them in a particular position.

Performance and Learning with Dr Robert Bjork and Adam Young

Today’s episode is all about learning and performance in golf and how this understanding should affect the way you practice and learn golf. Our two guests are Distinguished Research Professor Dr. Robert Bjork, and Adam Young, golf coach and author of The Practice Manual.

We’re answering questions like “Do we trick ourselves into thinking we’re improving, learning, and actually getting better?” and “What should we be going for in our learning environment?”. Start listening below!

Stop Wasting Time on the Driving Range with Dr. Tim Lee

Dr. Tim Lee is an expert in motor learning and he’s giving us an introductory look at how we’ve been falling short in our golf practice and learning environments.

In this episode you’ll learn about the nature of golf, what you need to know about random and block practice, and the actions you should start taking to create a better learning environment.

Interpreting Golf Research with Trillium Rose

Trillium Rose is the head director of instruction of Woodmont Country Club. She also has a Master’s Degree in Motor Learning and Control, which has “really helped shape my perspective and how I approach people’s learning, how they change their habits, and how improve their habits or learn new ones.”

Today we’re talking about what golf research is and how we’ve become a little confused with the role research vs inferences and observations plays in the growth of golf.

Understanding the “why” Behind Your Golf Swing with Golf Biomechanics Expert Dr Sasho MacKenzie

Dr Sasho MacKenzie, sports biomechanist, has spent years studying why and what takes place in the golf swing.

In this first episode of the Golf Science Lab we’ll talk all about his opinions, research, and what it means for you, the golfer. It’s a candid look into golf biomechanics (Dr MacKenzie’s speciality) and the implications of the research he’s been doing.

Listen to the conversation below and browse the story to view some insights into golf science whatever way you’d like.

How Putters Get Made w/ Austie Rollinson

Austie: Yeah the majority of what we do in putters is casting. But we do have a line of machine putters that we machine from forges. Whereas some people machine putter from billet steel. We do it from forging because we all forge the putter to a near nit shape. It’s just easier to machine it that way. It’s less material that you have to carve off of the putter so we can make them a little faster that way.

Cordie: What’s the definition of each of those? Casting and forging?

Austie: Well casting is called investment casting. So when you make a investment cast putter, you have to make a tool In order injack a wax representation of the putter. And then, that wax piece is put on what we call a tree which is a center column where they attach all these waxes to it and then they will dip it in a ceramic slurry, different ceramic slurry that build up this ceramic shell around those waxes. And they will put that whole tree into an oven to harden the ceramic and then the wax will melt out and that gives you basically a hollow shell that you can pour molten metal in. Basically cast, it’s called investment cast putter out of these stainless steel. It’s the way we make irons. It’s the same way we make titanium drivers. It’s the same sort of process. We pour molten metal in and it will harden and they will break off the ceramic around it, cut the metal off the tree and there you have the cast and you can polish them into a putter or an iron or a driver. It’s a really inexpensive fast way to make a bunch of parts. It’s very labor intensive but that’s why most of the manufacture is moved from the US. They move over to Mexico and now it’s moved to Asia because of the labor rate in terms of making those. A forged metal product is a little different because you will start with a bar of material and you will forge that into a shape that closely represents the shape of putter. And then that forging is then put into a CNC machine that basically the machines the putter, cuts the putter using putter bits and spindle heads out of the forging. And so that is a very time intensive process to be able to do that and the volume of parts that you can make there is a lot slower so that’s why machine parts are a lot more expensive than cast parts.

Cordie: Are there any pros and cons of those two routes to consider?

Austie: The machine parts you are able to put a lot richer finishes on them. From part to part will be a lot more consistent to putt than with the casting parts are. Although we have done, a lot of what we do with our suppliers that make the casting parts are working on ensuring the consistency from part to part versus the weight of the part as well as all the shape, the angles, what you see, the finish etc. It takes the finish to work to get the right standards to make sure they’re consistent. And so the machine parts you can do a lot richer looking finishes. The edges will be a lot crisper. They are more premium. They are more rare so there is that emotional connection to that type of product. From a performance standpoint, we can argue that if you have the same putter that’s machine versus cast, if you put an insert in both of those I think you’ll be hard press to feel the difference between. The look of them will be a lot different. So that golfer or the confidence of that golfer gets over the putter maybe different and then that emotional connection. That’s a really important part that I found over the years is that more than any other club in the bag golfers become very attached to that product because he use it more than any other golf club. And so they had relationships with them. Even today, there is a lot of golfers out there that have had the same putters since they were kids and they still use them. Others not so much so. They will throw them away every week and get a new putter. So I think it’s – and you know the machine putters as well they can do a lot of things in terms of using different materials in the same putter to achieve performance gains. And so we had a product that we have had over the years where we marry carbon steel of the putter in Thompson in order to get the center of gravity and the location that it enhances the roll of the ball. Get the center of gravity low and deep so we will do a Thompson flange at the back of the putter and that’s something it’s really hard to do in a casting to get the tolerances just right so the parts will marry up together. Whereas the machine part, you can machine up a bunch of flanges, a bunch of bodies, and you’ll get good together the same over time. And so, from that standpoint, machining has an advantage because you can do a lot more complicated things and play with materials to further enhance the mode of inertia and canter of gravity location on it.
