Sleep for better a better golf lesson?

Published

on

Have you ever practiced a golf drill one day and were about to give up, but the next day you tried it and you had a breakthrough?

I have noticed this sometimes with my clients and also myself. I remember when I was studying the mathematics in college I often needed some sleep before solving a difficult equation.

Now, Brown University professors Yuka Sasaki and Masako Tamaki have discovered that during your deep sleep, also called slow-wave sleep, the newly learned skills are confirmed by the brain. The big news from this discovery was that the brain processed the new information in another place than what had previously been thought.

The research based its findings on a test group of 16 volunteers (eight male and eight female), who were set up for a motor-learning task.

People who had the habit of taking a nap, consuming alcoholic beverages before sleep or smoking were excluded. All volunteers had to follow the same schedule (see chart below) before the training and the retest. The first three days for the group was only preparation and initialization before the actual training session of a motor task on the fourth day.

PSG (polysomnography) and MEG (magnetoencephalography) are technique for mapping brain activity.

During Day 4, the volunteers had to learn a sequence of finger tapping on their non-dominant hand. Then the test group had to sleep for four hours (post-training sleep). After their sleep they were asked to play the sequence again. Meanwhile another group had also done this finger-tapping training but without any sleep. The result was that the group that slept always did a faster and more accurate result than those who did not sleep.

There are many similarities with ordinary golf lessons. The golf coach gives you some swing thoughts that you try to accomplish. The brain processes these swing thoughts during your training session. According to the research, the primary motor cortex in the brain processes this kind of learning. During your sleep the next phase of your learning takes place. This time the supplementary motor area (SMA) seems to anchor what you learned into your memory.

So what can golfers take advantage from this discovery?

The most obvious answer would be that you should sleep enough before you attempt to learn some new motor skill. However, the research did not tell us if the time difference between the finger tapping until they slept made any difference on the result. What I am aiming at is this: should our golf training sessions be performed close to bedtime for the best results?

So I turned this question back to Masako to see if it has been included in their research. The answer I got was this:

“With regard to the time interval, previous studies show sleep-dependent improvement in visuo-motor learning, such as golfing, in both training in the morning and at night. Thus, the time of the day of training may not matter, as long as you are fully awake during the training, and sleep in the same day of the training (sleep deprivation will harm learning).

However, there is also a stage that seems not sleep dependent but could be important for visuo-motor learning. Suppose there are two types of learning, very similar but different (training A and B). If you train A first, then B immediately after A, they will interfere to each other, and you will not be able to see learning effect for either or both of the training types. If you have a certain time period between each session (10 minutes to six hours), this interference effect will not be shown.

To summarize, memory will be stabilized first within 10 minutes to six hours after training, when a memory becomes more resistant to interference from a competing memory. After the stabilization period, memory will be enhanced during sleep.”

I think this answer clarified my question without a doubt. There is no need for booking your golf lessons just before bedtime.

Another interesting thing that Masako mentioned was the possibility for interference between two training sessions (A and B). According to the research done by Masako and others, the best way to avoid mix up in your golf training was to separate the sessions, such as swing technique and short game training, with at least 10 minutes and at most six hours (without intervening sleep). Then the brain can remember and also separate the newly learned motor skill from each other. Under subsequent night the brain can then enhance the speed and accuracy of these motor abilities.

I imagine that many of you have participated in full days of golf training. Often this school includes training with the driver, irons, wedges, putter, etc. With the knowledge we gained from the research, maybe it’s just the last thing that you trained on that day that the brain could remember and improve until the next day. The other parts from that days training could even be worse than before.

golf shot range

My suggestion to you for better learning:

  • Avoid sleep deprivation before your training.
  • Take at least 10 minutes breaks between different training sessions, such as swing-related training and short game training.
  • Always perform your golf shots with a goal in mind.

Thanks to professor Masako Tamaki for answering my questions regarding this topic.

    Interesting article. Two things 1) Sounds like one should take it easy on the celebratory drinks that taste so good after a breakthrough round/practice session. 2) What keeps me going on the bad days, is knowing that it usually “clicks” the next time out. As long as you keep a level head and pay attention to what you dont want to repeat, bad swings offer as good a learning opportunity as the good ones.

    NaFlack. You’re a tryhard and your comment isn’t even relevant to the article. Just stop. I find it highly unlikely that if you actually had a 4 handicap you would make such an ignorant comment since you would likely understand how challenging a game it is to learn. Ben Hogan – secret is in the dirt.

      whatever the hell a “tryhard” is aside…
      i had been playing golf for 3 months and had just broke 90 for the first time when i came across a guy in the club house. he asked me what i shot and proudly stated 88! i then asked him what he shot and he blandly stated 78. i said no way, what did you really shoot?
      he pulled me aside and asked me what right i had to assume that he could or couldnt shoot a score? we agreed to play together and he showed just how someone could shoot such a score and not be jazzed about it. he explained as we walked to our cars that putting my assumed limitations on ohers doesnt do me any good and it makes me look like a jerk. then he asked why should it matter how someone else does…?

        We should all encourage everyone to continue to play no matter what the score. This is a great game and if too many people dont support golf, the local muni and even the semi’s will struggle to stay in business. Then we will all be left without a place to play unless your plunking down a good chunk of change.

          We should respect people enough to let them decide for themselves. No one should be encouraged to play golf by golf marketing firms or people whose concerns have noting to do with the individual playing. If they want to, let them, if they don’t want to, let them. It isn’t anyones responsibility to worry about the industry. It really chaps my behind to know that the entire equipment industry is propped up by people who struggle with this game and are promised art every turn that this piece of equipment or swing theory will fix it all. I take comfort in knowing that the day I can no longer shot the score “I” deem acceptable I will give up the game. That decision is my business to make and should have no influence on anyone who is truly secure in their relationship with the game of golf.

    being a self taught 4 index, which i know is not great but good enough to “enjoy” the game…i just cant understand why anyone would bother with this game if they needed to do so much just to learn it.
    if i took a few lessons and with one season under my belt still couldnt break 90 i would find something else to do with my time and money. life is too short as it is.

      Maybe you are a natural talent. Not everyone is born with great hand eye coordination or natural athleticism. I’m a scratch holder and used to be a pga apprentice so I have seen the habit of golfers out there and you are lucky sir.. at the same time you are probably a cynical douche tgat none of your friends really want to play with. Golf is hard there’s no need to put people down the wsy you did by saying you woukd kill yourself if you didn’t break 90.

        the people i play with regularly like to play with me, some are scratch and some dont break 100. they give me a hard time because i dont play with them as often as they want me to. i never say anything critical about any shot any of my friends play. i am well aware that some take to things better than others. what does my take on breaking 90 have to do with anyones ability or enjoyment? not to mention suggesting i would find something else to do is nothing close to suggesting i would kill myself. if you knew me you would know first hand i am anything but lucky…

      Wow. There are not that many 4 indexes out there. Is this your secret ploy to clear up all the public courses?

        This is becoming comical…a 4 is nothing special!
        I am the 4th or 5th best player in the group of roughly 10 guys I regularly play with. They tease me for only being able to bunt it out there 260. Are the guys better than me also liars because there is just no way anyone could be that good? Rhetorical, I already know most of you would clearly say yes, lol.

The Wedge Guy: The easiest-to-learn golf basic

Published

on

My golf learning began with this simple fact – if you don’t have a fundamentally sound hold on the golf club, it is practically impossible for your body to execute a fundamentally sound golf swing. I’m still a big believer that the golf swing is much easier to execute if you begin with the proper hold on the club.

As you might imagine, I come into contact with hundreds of golfers of all skill levels. And it is very rare to see a good player with a bad hold on the golf club. There are some exceptions, for sure, but they are very few and very far between, and they typically have beat so many balls with their poor grip that they’ve found a way to work around it.

The reality of biophysics is that the body moves only in certain ways – and the particulars of the way you hold the golf club can totally prevent a sound swing motion that allows the club to release properly through the impact zone. The wonderful thing is that anyone can learn how to put a fundamentally sound hold on the golf club, and you can practice it anywhere your hands are not otherwise engaged, like watching TV or just sitting and relaxing.

Whether you prefer an overlap, interlock or full-finger (not baseball!) grip on the club, the same fundamentals apply.  Here are the major grip faults I see most often, in the order of the frequency:

Mis-aligned hands

By this I mean that the palms of the two hands are not parallel to each other. Too many golfers have a weak left hand and strong right, or vice versa. The easiest way to learn how to hold the club with your palms aligned properly is to grip a plain wooden ruler or yardstick. It forces the hands to align properly and shows you how that feels. If you grip and re-grip a yardstick several times, then grip a club, you’ll see that the learning curve is almost immediate.

The position of the grip in the upper/left hand

I also observe many golfers who have the butt of the grip too far into the heel pad of the upper hand (the left hand for right-handed players). It’s amazing how much easier it is to release the club through the ball if even 1/4-1/2″ of the butt is beyond the left heel pad. Try this yourself to see what I mean.  Swing the club freely with just your left hand and notice the difference in its release from when you hold it at the end of the grip, versus gripping down even a half inch.

To help you really understand how this works, go to the range and hit shots with your five-iron gripped down a full inch to make the club the same length as your seven-iron. You will probably see an amazing shot shape difference, and likely not see as much distance loss as you would expect.

Too much lower (right) hand on the club

It seems like almost all golfers of 8-10 handicap or higher have the club too far into the palm of the lower hand, because that feels “good” if you are trying to control the path of the clubhead to the ball. But the golf swing is not an effort to hit at the ball – it is a swing of the club. The proper hold on the club has the grip underneath the pad at the base of the fingers. This will likely feel “weak” to you — like you cannot control the club like that. EXACTLY. You should not be trying to control the club with your lower/master hand.

Gripping too tightly

Nearly all golfers hold the club too tightly, which tenses up the forearms and prevents a proper release of the club through impact. In order for the club to move back and through properly, you must feel that the club is controlled by the last three fingers of the upper hand, and the middle two fingers of the lower hand. If you engage your thumbs and forefingers in “holding” the club, the result will almost always be a grip that is too tight. Try this for yourself. Hold the club in your upper hand only, and squeeze firmly with just the last three fingers, with the forefinger and thumb off the club entirely. You have good control, but your forearms are not tense. Then begin to squeeze down with your thumb and forefinger and observe the tensing of the entire forearm. This is the way we are made, so the key to preventing tenseness in the arms is to hold the club very lightly with the “pinchers” — the thumbs and forefingers.

So, those are what I believe are the four fundamentals of a good grip. Anyone can learn them in their home or office very quickly. There is no easier way to improve your ball striking consistency and add distance than giving more attention to the way you hold the golf club.

Clement: Stop ripping off your swing with this drill!

Published

on

Not the dreaded headcover under the armpit drill! As if your body is defective and can’t function by itself! Have you seen how incredible the human machine is with all the incredible feats of agility all kinds of athletes are accomplishing? You think your body is so defective (the good Lord is laughing his head off at you) that it needs a headcover tucked under the armpit so you can swing like T-Rex?

How a towel can fix your golf swing

Published

on

This is a classic drill that has been used for decades. However, the world of marketed training aids has grown so much during that time that this simple practice has been virtually forgotten. Because why teach people how to play golf using everyday items when you can create and sell a product that reinforces the same thing? Nevertheless, I am here to give you helpful advice without running to the nearest Edwin Watts or adding something to your Amazon cart.

For the “scoring clubs,” having a solid connection between the arms and body during the swing, especially through impact, is paramount to creating long-lasting consistency. And keeping that connection throughout the swing helps rotate the shoulders more to generate more power to help you hit it farther. So, how does this drill work, and what will your game benefit from it? Well, let’s get into it.

Setup

You can use this for basic chip shots up to complete swings. I use this with every club in my bag, up to a 9 or 8-iron. It’s natural to create incrementally more separation between the arms and body as you progress up the set. So doing this with a high iron or a wood is not recommended.

While you set up to hit a ball, simply tuck the towel underneath both armpits. The length of the towel will determine how tight it will be across your chest but don’t make it so loose that it gets in the way of your vision. After both sides are tucked, make some focused swings, keeping both arms firmly connected to the body during the backswing and follow through. (Note: It’s normal to lose connection on your lead arm during your finishing pose.) When you’re ready, put a ball in the way of those swings and get to work.

Get a Better Shoulder Turn

Many of us struggle to have proper shoulder rotation in our golf swing, especially during long layoffs. Making a swing that is all arms and no shoulders is a surefire way to have less control with wedges and less distance with full swings. Notice how I can get in a similar-looking position in both 60° wedge photos. However, one is weak and uncontrollable, while the other is strong and connected. One allows me to use my larger muscles to create my swing, and one doesn’t. The follow-through is another critical point where having a good connection, as well as solid shoulder rotation, is a must. This drill is great for those who tend to have a “chicken wing” form in their lead arm, which happens when it becomes separated from the body through impact.

In full swings, getting your shoulders to rotate in your golf swing is a great way to reinforce proper weight distribution. If your swing is all arms, it’s much harder to get your weight to naturally shift to the inside part of your trail foot in the backswing. Sure, you could make the mistake of “sliding” to get weight on your back foot, but that doesn’t fix the issue. You must turn into your trial leg to generate power. Additionally, look at the difference in separation between my hands and my head in the 8-iron examples. The green picture has more separation and has my hands lower. This will help me lessen my angle of attack and make it easier to hit the inside part of the golf ball, rather than the over-the-top move that the other picture produces.

Stay Better Connected in the Backswing

When you don’t keep everything in your upper body working as one, getting to a good spot at the top of your swing is very hard to do. It would take impeccable timing along with great hand-eye coordination to hit quality shots with any sort of regularity if the arms are working separately from the body.

Notice in the red pictures of both my 60-degree wedge and 8-iron how high my hands are and the fact you can clearly see my shoulder through the gap in my arms. That has happened because the right arm, just above my elbow, has become totally disconnected from my body. That separation causes me to lift my hands as well as lose some of the extension in my left arm. This has been corrected in the green pictures by using this drill to reinforce that connection. It will also make you focus on keeping the lead arm close to your body as well. Because the moment either one loses that relationship, the towel falls.

Conclusion

I have been diligent this year in finding a few drills that target some of the issues that plague my golf game; either by simply forgetting fundamental things or by coming to terms with the faults that have bitten me my whole career. I have found that having a few drills to fall back on to reinforce certain feelings helps me find my game a little easier, and the “towel drill” is most definitely one of them.
