The reasoning is many skilled movements such as throwing, kicking, dribbling, shooting, catching, etc become so developed into our "muscle memory" that when you perform them, they are largely done unconsciously - without thinking about it.
When crunch time hits, many athletes begin to suddenly analyze and consciously think about these ingrained movements. Instead of relying on the build movement pattern/skills they've ingrained over the years, they now move towards consciously thinking about each movement process.
In short - paralysis by analysis. Athletes now lose natural movement patterns they've built over the years and now get labeled for "choking" under the pressure.
Squeezing your left hand increases the activity of the right hemisphere in your brain. The right hemisphere is associated with performance in autmated or unconscious behaviors. So in theory squeezing with your left hand brings your brain back to it's right hemisphere, and to a more natural, unconscious mindset, which is ideal for many athletic skills.
This reminds me of the 'Tube Tuesday we posted a couple weeks back with Dr. Daniel Wolpert. He suggests that the real reason for our brains is for Movement. If you missed that Check it out here
'Tube Tuesday - Daniel Wolpert - The Real Reason for Brains
This should come at a limited suprise. We know how influential the brain the Central Nervous System are in controlling our bodies. Just more reason that S&C coaches need to understand the role of the Brain and CNS, and it's not all about the muscular system. The CNS is the driver and control master, the muscular system does what it's told and follows the commands. The muscular system is extremely important, but we need to understand it takes a back seat to the CNS.
That's all for today, so Go Get 'Em!
