Re: Poll: How effective is learning aikido through a purely visual media (videos, DVDs, software, etc)?
I looked for a link, but found none. I'll relate a study done a few decades ago:
College basketball team split - one group physically trained, one group visualized under coaches direction - same regimen as physical team. The 'mind only' team got better as measured by their physical skill level.
My physical therapist, who has studied neurology in depth suggested I get video of the master in my martial art. He said that if I make an 'efferent image' and repeat this over and over in my mind I will develop the skill I am imaging. 'Efferent' refers to nerves that carry signals from the brain, in this case to my muscles.
I have improved. FWIW
