Spurs Shooting Drill

[Kori Ellis]

The Spurs have a drill where they shoot 100 three-pointers. Brent Barry holds the record with 94 out of 100. So we (Don Harris & David Chancellor) were thinking, how tough can it be?

In the drill you shoot 60 shots (I think six from each of the five spots on the floor and then repeat it), then you shoot 30 (with running between the spots) and then you shoot 10 (with a lot of running between the spots). Brent's 94 is a crazy number, but I'm impressed that so many of the Spurs had records in the 80's. Pretty good testament to how good of shooters NBA players are.

On The Golf Tee Or Pitcher's Mound, Brain Dooms Motion To Inconsistency

Science Daily — If you've ever wondered why your golf swings, fastballs or free throws don't quite turn out the same way each time, even after years of practice, there is now an answer: It's mostly in your head. That's the finding of new research published in the Dec. 21 issue of the journal Neuron by electrical engineers at Stanford University.

"The main reason you can't move the same way each and every time, such as swinging a golf club, is that your brain can't plan the swing the same way each time," says electrical engineering Assistant Professor Krishna Shenoy, whose research includes study of the neural basis of sensorimotor integration and movement control. He, postdoctoral researcher Mark Churchland and electrical engineering doctoral candidate and medical student Afsheen Afshar authored the study.

It's as if each time the brain tries to solve the problem of planning how to move, it does it anew, Churchland says. Practice and training can help the brain solve the problem more capably, but people and other primates simply aren't wired for consistency like computers or machines. Instead, people seem to be improvisers by default.

A major conclusion of the study, in fact, is that movement variability is not primarily a mechanical phenomenon, as had widely been thought. After looking at neural activity and muscle activity, the Stanford researchers concluded that less than half the reason for inconsistency in movement lies in the muscles.

"This is the first study to successfully record neural activity during the planning period and link it on a trial-by-trial basis to performance during those trials," Churchland says.

The Stanford team decided to do just that with the help of rhesus macaque monkeys. The monkeys were trained to perform a simple reaching task. When shown a green spot, they were rewarded with juice if they reached slowly to touch the spot. For a red spot, they were trained to reach fast. During the trials the researchers would monitor the activity of individual neurons in the premotor cortex, a part of the brain responsible for movement planning, while the monkeys were planning their reaches. Then the researchers would record the speed of the resulting motion.

Over a series of thousands of trials, the researchers observed subtle variations in the speeds of the reaches. The monkeys rarely reached with the same exact speed, whether for a green or red spot. More importantly, after some sophisticated statistical processing, the scientists found the small variations in reach speed were predicted by small variations in brain activity during movement planning, before the movement even began.

Flexibility beats consistency

For athletes, the inability to replicate the perfect movement might seem to be a frustrating problem that needs to be solved. But the researchers speculate that the brain has evolved its apparently improvisational style precisely because the vast majority of situations requiring significant movement are novel. Predators never get the chance to catch and kill prey in exactly the same fashion and in exactly the same conditions.

"The nervous system was not designed to do the same thing over and over again," Churchland says. "The nervous system was designed to be flexible. You typically find yourself doing things you've never done before."

The value of practice and training is that they can reduce the variation in the mind's abilities, but they don't change the variable way the mind plans motion. An analogy might be to doing math problems. Someone who has studied will find it easier to solve a new problem than someone who has not prepared.

Given the endemic nature of movement variability, the research doesn't point to any definitive means for combating it. In their paper, the engineers offer no advice for baseball trainers to help pitchers throw more strikes. A potential application of the research, Shenoy says, could come in future efforts to achieve new kinds of computing by building artificial circuits modeled on the brain. But Shenoy says the research simply set out to explain variability in movement.

"This is basic science," Shenoy says. "We ask questions because we want to know."

The study could help resolve a question about human nature, however. Which is more true, "nobody's perfect" or "practice makes perfect"" If complete consistency is the standard of perfection, then it seems that nobody will ever be perfect.

:lol My post was about a 3-point drill -- where they aren't defended. So of course they are much better shooters than in a game under mental and physical pressure. It didn't have anything to do with freethrows, so I don't know the point of your re-post of the article. But Merry Christmas anyhow. :lol

I just thought the video was funny. Chancellor throws up in the middle of the drill :lmao

[TDMVPDPOY]

if tim duncan can shoot 80/100 3pts in practice, than he should do it during games and think the defenders as invisible men.....

"Oxygen, it's a pretty big part of living. Isn't it?"

:lmao

[usckk]

Matt Bonner in 2nd!! He should play more.

[Pero]

Didn`t Stojakovic score a 100 (or more?) straight?
Very funny video. :lol

damn... when i was hitting the gym everyday or so a couple of years ago... at my best i could hit around 50-100... and that's without the running drills. i thought i was pretty good :depressed
