Cubing injuries and the dexterity barrier.

Post by Jome on Wed Mar 19, 2008 11:06 pm

Apparently, the theoretical dexterity barrier actually does exist.

Tonight, just minutes before the time of this writing, I broke my index finger practicing the Nakajima Z-perm. I advocated to bring it down to sub-2, hence I practiced on it alone since last night. Apparently, a little too much can indeed make a finger break. I wasn't able to time it properly (but I reached a PB of 2.14s prior to the accident via JNet) because at the R2 part, my index finger snapped while I was slide-pushing the R face.

So this goes to show that a dexterity barrier does exist, but most cubers don't notice that they break it over time. However, some cubers who do not excel that well in fingertricks might find it hard (and painful) to overcome.

So, I guess I'm stuck at OH. So much for getting two new cubes. Haha. And yes, I'm typing without using the right index finger. Go figure. Smile

I agree absolutely!!!

I realized this fact a few months ago when i realized i was getting stuck at 21seconds. The limit of our finger dexterity, and recognition ability is somehow related to our brain functions, and this has already been genetically proven. (I'm not talking about IQ, it's totally different. i'm talking about finger-brain coordination). There are gifted cubers (like nakajima) who can be sub-20 in just 2 months because of their extremely powerful mind-finger coordination, and there are hardworking cubers (like me) who cannot reach sub-20 after 14 months of cubing. With the same amount of effort during practiced, a hardworking gifted cuber will definitely accomplish much more than a just hardworking cuber.
the same thing happened to me with the piano. I realized that there is also a limit to the level of difficulty of the piano pieces that my fingers can play, no matter how hard i practice.
But the good news is, practice can still work!!! I can actually be like nakajima if i work even harder. The brains actualy grow new nerve cells through mental exercise like puzzle solving. Perhaps, i can be sub-12 in the 3x3 too, but it will take several years (haha!) But who cares? as long as i'm having fun... i don't give a damn.

ok i had to look up the meaning of dexterity hahaha! yay jome hope you get better soon! time for me to catch up with you!! Laughing no seriously sana gumaling ka agad.

actually i've been thinking about this for sometime now. antagal ko ng sub25. i can't seem to break through even the sub22 barrier. it makes me think if i can even break sub20 any time soon. maybe i'm just putting too much pressure on myself setting a deadline that i don't necessary have to achieve. with that in mind i have decided not to overdo myself in order to avoid injuries hehe. however, thanks to this thread nadagdagan ang aking passion for speed! i know i will achieve sub20! with God's help i can even be sub11! cheers

Pajo is indeed correct about the hand-eye coordination. Apparently, I can execute algorithms faster with my eyes closed than when I have them open. The eyes tend to 'want' to see the execution to the point that your hands themselves slow down.

I tried executing all 21 PLL algorithms blindfolded and realized that when you don't see or imagine the execution and movement, the hands themselves tend to move. This is evident in the spaced out LL moments of top cubers. Even former world champion Dan Knights said that muscle memory is indeed the best executor of algorithms and not visual memory.

To add, the dexterity barrier does exist for as long as you decide not to reach the fastest speeds possible. After my finger fully recovered, I found my average dropping by 2 full seconds. I don't understand how it went that way and I plan on fully watching the progress of my times. Hanggang ngayon, I am still amazed at how I broke the sub-20 without even thinking about it.
