Welcome to Play Smart, a game-improvement column that drops every Monday, Wednesday and Friday from Game Improvement Editor Luke Kerr-Dineen to help raise your golf IQ and play smarter, better golf.

We get it. You probably know by now that more distance would probably help your game. But how do you actually get more of it without sending your ball off the planet in the process? That’s the big question.

And it’s one the team over at Super Speed Golf are taking a crack at answering.

The company, whose products range from a three-piece speed training set to a newly-released portable launch monitor, recently conducted a yet-to-be-published speed study led by Utah Valley University biomechanics professor Dr. Tyler Standifird.

The study followed 15 golfers, who ranged in handicap from 1 to 20, for six weeks as they completed the company’s level 1 SuperSpeed training protocol. Throughout the six weeks, Standifird used a Trackman to collect club and ball metrics, along with Bertec force plates and a Qualisys motion capture system to measure how golfers’ swings changed — specifically, their ground reaction forces.

By the end of the six weeks, the group gained, on average, 5 mph of clubhead speed, 8 mph of ball speed, and 16 yards of carry distance.

That speed didn’t arrive magically, though. As expected, the thrice-weekly training sessions altered golfers’ swing itself in one particularly interesting way.

More weight transfer back and through

When pitchers want that little bit of extra heat, they wind up a little more. When golfers want to really send one, they make a bigger backswing. That truth is one golfers have known intuitively for a long time, and SuperSpeed’s findings shed some more interesting details about how that actually works.

At the start of the study, Dr. Standifird found that at the top of the backswing, golfers had about one-third of their body weight situated on their lead (front) leg, and two-thirds sitting on their trail leg. They had increased their “trail leg vertical force at the top of their swing” by 21 percent, and decreased their “lead leg vertical force” by about 22 percent.

In simple terms, golfers had shifted more weight to their trail leg at the top of the backswing (about three-quarters of their body weight, in all) by the end of the study.

But they didn’t just increase their weight shift on the backswing. They also increased it quicker in the opposite direction on the downswing, too.

By the time the club gets vertical to the ground on the downswing, golfers had shifted about 75 percent of their weight back to their lead (front) leg. Notice how Justin Thomas’ trail foot is coming off the ground at this point? That’s because most of his weight, at this point, is moving to the other leg. At the start of the study, golfers were slower to transfer their weight back to their lead leg — and it was costing them speed.

Of course, this change wouldn’t have been possible without actively training this movement via the program. And technically speaking, the big key is making sure you do this without swaying in either direction as you swing. But all things equal, a big, loaded turn is the key for speed. Do that right and you could see your clubhead speed jump, too.
