‘Precision under pressure’

We use this term is several of our recent posts. It’s an idea that needs further explanation.

I’ll start by summarizing our theory of time perception in the brain: proportional to stress. So the more stress, either external or internal, the slower time is perceived. There is not shortage of application or development of this theory in other posts. 

This is important because brain entropy is internal pressure. The more stress we put on athletes, mental or physical, the more brain entropy they have, and the slower they perceive time.

How does that apply to precision? Imagine your golf swing as a single fluid motion. If you are 50% accurate with your swing, about half the balls will go where you want them to. But if your swing has two motions, there is twice as much room for error. So the more thought you have in your swing, the less accurate it can be. And the more stressed you are, the slower time is for you. The more time for thought in the swing, and more room for error on the shot. Therefore, less stress equals less entropy equals faster time perception which equals more accurate movements over a longer period of time.

This is why a swing will break down under pressure. And why a natural athlete needs to be aware of the fundamentals of their practice. Because in crunch time, things feel different. You have more time to swing, throw, or kick. So if you don’t know how to tune out the pressure or adjust to it, you will become unpredictable over time.

This is why practice is crucial. You practice to develop your skills but also tune them to each level of stress. If you casually hit tennis balls every day, you may not be match ready. There is more stress. And as the match wears on, you get more tired, which also increases stress.

With this in mind, you can start to see the advantage of a bigger brain. The bigger the brain, the greater the volume the athlete can reach without reaching the same level of entropy. There is essentially just more room for pressure.

And when pressure gets high, entropy gets high, and time gets slow. And when time gets slow, it gets harder and harder to accurately do the same thing over and over again with predictable results.

 

The Biggest Brain of All

Nearly every Olympics sees Chinese champions in certain events. They dominate ping pong, gymnastics, shooting, badminton, diving, and weight lifting. The question is why.

We recently explore the athletic head, and used it to explain the racial disparity of some sports. We then looked at the bigger head and used our model to predict and explain the advantages of having a bigger brain in sports. Well, the Chinese brain is the biggest of all. 

So why would the group with the biggest brains in the world dominate these sports?

Badminton and ping pong are repetitive and very precise repeated movements. A bigger brain helps make these movements more predictable over time.

More precision under even more pressure. Diving and gymnastics are choreographed. They come down to who can execute the most difficult routines with the most precision.

Even more sleep. With an even larger brain, it takes even longer to cool off.

Less muscle endurance. The brain uses more energy leaving less for the rest of the body.

Why do they dominate weightlifting? You would assume that the smaller brain with the best acceleration would be king here. It’s just not the case. 

So lets assume that you have two people that are the exact same strength and exact same weight. One has a larger brain. The lift itself becomes more of a choreographed dance at this point. The lifter who can have the best form, while staying relaxed will lift more weight. The smaller brain, although with a greater ability to accelerate, also has much more room for error. Under duress, the smaller brain could produce less predictable movements. Or worse form. The smaller brain would reach its pressure threshold first, leaving the larger brain the winner.

The Advantages of the Bigger Brain in Sports

We recently explored the athletic head. What about the rest of us?

A bigger skull means a lower likelihood of stroke. The bigger the skull, the lower the chance of it reaching its pressure limit.

Better mental endurance. Thinking for longer periods of time.

More sleep required. More time will be needed to cool off this entropy. Even if the brain has the same theoretical temperature, the larger volume will take longer to cool off.

More precision in pressure. I always think of Tom Brady or Peyton Manning. If bigger brains play with more precision over time, it seems like atmosphere, time, and other conditions would not effect the large brains as much.

Better at repeatable movements over a long period of time. While the small brains fire more quickly, they also have less precision and endurance. I would look at the massive racial disparities in golf and tennis

I think we have to assume that economics alone do not explain this disparity. We have to assume that if there was a massive pool of untapped talent hiding in low-income communities, someone would’ve found it by now.  

 


 

Let’s look at home field advantage again with this in mind. The black-dominated sports have the biggest home field advantages. And the white-dominated sports have much less of an advantage at home. In that article, we said that it was the nature of the sport that was the difference in the home field advantage. I think there is more to the story.

So why is home field advantage so strong in the NBA?. Because speed and explosiveness come at a premium. It doesn’t matter if you have someone who literally has never missed a three-pointer in his life, if he can’t move and get the shot up quickly, he can’t play in the NBA. So if speed and explosiveness come at a premium, the fastest and most explosive people will likely be better at it. If I have a team of track stars and you have a team of shooters, we’ll win because we can run past the defense and shoot a higher percentage. We’d also have better close-out defense, and get more rebounds. So instead of having the absolute best shooters on the planet in the NBA, we have the best athletes that can shoot. 

Why is hockey so different? Why is its home field advantage so much less than basketball? Because explosiveness is undervalued. Apollo Ono could be on the ice but never make a huge difference. The rink is shorter, so there are fewer breakaways, and nobody leaves the ice. So jumping doesn’t matter.  Precision is important, but explosiveness is not premium. 

So the nature of the sport determines the type of athlete that is most valued. That value determines the type of brain that can perform best under the conditions of the sport. Those criteria determine which races dominate different sports. And those races determine the relative difference of home field advantage.

The Athletic Head: The Real Advantage of Race in Sports

We’ve written about race in sports before. That’s actually where this whole thing started unraveling for me.

There’s a statistical discrepancy in the skull size of black people and others: they’re smaller. There’s some debate as to what it means and if there is even a discrepancy at all. Let’s just assume for a minute that the African brain is smaller on average than other brains. 

Why is that important? Because with our brain entropy model, this smaller-skulled race would have an athletic advantage. Especially in “fast twitch” events. Because the engine is smaller, it takes less energy to start, and therefore can start quicker.

White people can’t jump. If you assume that the more entropy you have in the brain, the slower the time perception, smaller brains would be much more likely to jump higher and run faster.

Faster recovery. If we also assume the brain is made of the same substance, this smaller brain would also cool off faster when overheated. Another advantage in most sports.

Less sleep. If sleep cools the brain, a smaller brain would mean less cooling, and less sleep necessary to zero out entropy from the day. We’ve explored this concept before. 

What about all those great distance runners from Kenya? I’ll just put this here. Brain_Size_Map.png

But also, this race has a much greater risk of death by stroke or heart attack. How does that relate? A stroke happens when your brain pressure gets too high. For smaller brains, higher pressure is easier to attain. So the same mechanism that gives them an advantage at sports, increases their risk of early death.

Assuming that the African brain is smaller, we can predict most aspects that set them apart as athletes as well as their sleep patterns and elevated risks of heart attack and stroke.

Don’t Move the Line Back

If you want to change the game, change the value of the shot.

The problem is not how good the players are getting at threes. Is how lopsided the valuation of the shots is. A good shooter makes 50% of their twos. To make the expected value the same, a three point shooter needs to shoot 33%. Which isn’t even a good number, nowadays.

For a shot that’s only 17% percent harder, it’s valued 50% more. It was only a matter of time until shooters were going to spread the court and light it up.

So to fix the problem, I’d suggest addressing the point value. While it would be a mess on paper, value the old 3’s at 2.34 points. You don’t have to repaint anything, and you naturally shift the game back to what it used to be. Too much post play at that number? Bump it to 2.5.

The scoreboard may get messy, but it may be worth it. Plus, you can keep the game style steady by adjusting the points as needed before the start of season.

What causes knockouts?

Preliminary reading: Concussions Do Not Cause CTE and Concussions Resolve Themselves

Stress and blood pressure builds over the course of the fight, and the volatility of the boxer increases as he gets tired and damage is done.

By the end of the fight, it takes much less of a blow for the boxer the cross the pressure threshold and lose consciousness. So even as the punches lose power, the boxers are still more and more likely to get knocked out.

Each punch raises the internal pressure of the brain system of the boxer. While they recover between rounds, and between blows, the threshold for a mini-stroke becomes lower and lower. Once that threshold is reached, lights-out.

Dear Tiger Woods,

You aren’t trying to be the healthiest golfer in the world. Do not change your diet. Or if you do, keep in mind that your game may change as well. Lowering your weight does not necessarily lower your score. Look at Brooks Koepka or Jason Dufner. There are all sorts of examples.

You aren’t trying to be the strongest golfer in the world. Yes, extra yards off the tee are great, but they don’t mean anything if you can’t get the ball in the cup. Take it to the extreme and you have the Hulk Hogan wannabes hitting the balls half a mile, but they couldn’t hold a torch to the average pro player. Tiger and Rory are exceptions not the rule. And they have had to make major adjustments after they started really hitting the weight room. And they have had their struggles around the greens.

The sport is a very delicate balance of slow and fast switch, power and finesse, and mental endurance. And as we’ve demonstrated in our article about pitching, gaining fast twitch muscles comes at a price.

Your trainer is not a professional golfer. If he was, he wouldn’t be a trainer. He knows how to get you in better shape. If he knew how to make you the best golfer in the world, he would be the best golfer in the world.

Your nutritionist is not a professional golfer. He just isn’t. So start keto or slow carb or whatever so you look better at the beach, but it will come at a cost. Your brain is the most delicate organ of your body. And your nutritionist does not know how your brain works.

What matters is results. Your job is to shoot low. If your trainer or nutritionist takes you down a path that changes your golf game in a negative way, kick the diet. Kick the workout routine. Otherwise you give away your edge. You’re not trying to be the best golfer in the world with a six-pack. You’re trying to be the best golfer in the world.

No one knows how you got to where you were. If they did, they would be there. If anyone asked you, you probably told them that it was all the hours you put in on the range growing up. I won’t argue with that. But I bet you didn’t make drastic diet changes during your teenage years while you were developing your swing and ironing out the kinks. So when you make these changes, be prepared to go back to the drawing board. And there is no one in the world that can get you back to where you were, except you.

Why Can’t DB’s catch?

Hint: It’s the same reason that Shaq couldn’t consistently make free throws. It’s the difference between the start and the finish of the 100-meter dash. 

Their instincts are to chase, to disrupt, to defend. They are typically quicker than the receivers, but can’t catch a cold. Why is that?

It’s because of their mindset. They are in fight-or-flight mode. And the catch is a delicate maneuver.

Receivers have a set path, and a plan of attack. The defensive strategy is entirely reactive, based on what they see from the offense. So thinking quickly is part of their programming. The problem is that thinking quickly does not help you catch a football.

Think about it…receivers catch more passes when they are hit in stride, and don’t have to react or adjust to a bad throw. It’s because the act of changing the path and reacting to an off-target throw takes more energy, and the time is the same.

Look at the catch rate of these receivers. Does it remind you of the free throw percentages in the NBA? It should. Receiving stats look just like free throw stats. The best catchers hover near 90%, and the worst are around 50%, some even dip below 40%. And you know what they call receivers that catch less than 50% of their passes: defensive backs.

Decoding Free Throws

Why can’t some NBA players shoot free throws?

It seems simple. But when you dive in, you realize that it’s a much more intricate problem. We know that countless teams have had infinite time and money to solve this problem, but you still have superstars that can’t shoot any better than someone chosen at random in your neighborhood gym. 

Let’s rule out some arguments. 

It’s not because they are tall. The NBA is filled with tall people that can shoot. Look at Kevin Durant or Dirk Nowitzki. 

It’s not genetics. We’ve already dug into genetics. Gene’s change over time, anyways. There may be some portion that is inherited, but it shouldn’t prevent anyone with twenty years of experience from shooting 70% from the line. 

It’s not the amount of practice they put in. These athletes have dedicated their lives to the sport, so it’s not fair to say that practice is the difference. I think it’s safe to say that Shaq spent at least as much time shooting free throws in practice as Steve Nash. 

Your best athlete is never your best free throw shooter. Unless, you just don’t have any above average shooters. The mindset of an athlete is fast. And the faster the mind, the better the athlete. But at the solitude of the stripe, accuracy and reproduction of the stroke are key, and just like pitchers are endurance athletes, your best shooters will be endurance athletes as well.

Think about it: LeBron, Kyrie, Iverson. Not to mention Russell Westbrook and John Wall, who are shooting under 70% from the line.  They certainly shoot at a higher clip than you or me, but they will never touch Steve Nash or Steph Curry.

Why couldn’t Shaq make free throws?

It’s because these strong guys typically have much more energy than the shorter guys. When they run the court, it takes them longer to settle in. Basically, he uses more energy to do the same amount of work, in part, because he’s big, but also because he’s quick. The faster his mind cycles during his dash down the court, the longer it will take it to slow down enough to shoot. And they don’t give him any more time to shoot just because he’s bigger or pushing himself harder than anyone else. So he has to shoot before he’s ready. Before he’s comfortably at rest. So he flips a coin. 

Shaq, Deandre Jordan, and countless others know only one speed on the court, and that’s full speed. Maximum exertion. The problem is the free throw line rewards those who play in the opposing mindset. We’ve explored how pitchers are endurance athletes. The best shooters are endurance athletes as well. Not because shooting free throws takes any kind of aerobic capacity, but the higher the capacity, the lower the energy of the player when he starts shooting. And that means a shot that’s easier to replicate, and more accurate. 

What is your typical rate of play? How much do you exert yourself to play at that speed? The more efficient and effortless your movement is, the less added strain you’ll have when you go to the line after getting fouled. And the less time you’ll need to settle in to a state of mind that can sink free throws with more precision.
