Training the brain The so called 'practice' is all about training the brain. We evolve each and everyday, but the fact is - the word evolution is applicable only to the brain. A child crawls in the initial stages and later puts on effort to walk. The practice sessions when the child is trying to walk is about training the brain to balance and not to train the legs or arms. Similarly let us consider the art of Kung fu, the martial art which involves quick movements of the limbs in order to attack or defend from the enemy. During the practice sessions of kung fu, it the brain which gets trained to make really quick movements of the limbs. In other words, its all about training the brain to give respective electrical impulses in responses to the impulse it receives. According to this fact, if something can 'teach' the brain to make the quick movements by some other means (like installing data extracted from another person who has mastered kung fu), there is no need of the brain to learn them by several hours or days of practice. But such a kind of 'installation' may not be possible for another few decades as the brain is said to be too complex. Let us consider this example... A man is going to the gym to develop his muscles. When he does the exercise, initially it will be easy to do, but as he stretches his limits, the body sends signals to the brain that the current muscle power is not enough to do such 'hard work'. So the brain responds to these signals and instructs the body to provide more nutrients to develop muscles in that area. So its ends up like this, if the brain can instruct the body to develop the muscles in the arm or anyother area, the body can do so. Then there may be no need of doing the exercise at all. However there is a difference between the Kung fu and the gym. The kung fu cannot be taught to the brain without the source of intelligence. But the brain can be easily deceived to the 'fact' that there is more muscle needed at some part of the body. According to an article published in the TIME magazine, a group of researchers did the following experiment. Four people were asked to play a piano and the chemical reactions in the brain were recorded. While another four people were just asked to 'think' about playing piano, surprisingly the same kind of chemical reactions were spotted in the brain. It is obvious that the brain can be deceived through mere 'imagination' is it is a 'reality', but upto what extent is the million dollar question. Some real world proof that the brain can be 'cheated' are 1. Saliva secrets in your mouth just by the imagination of a delicious food. 2. You scream out from a nightmare because your brain beleives that the incident is a real one. If we can 'cheat' the brain that we are struggling to do a 'work' due to lack of muscle power through very powerful thought process, can we really develop muscles? Yes, it can be done, but to what extent? While the above ideas cannot be applied in real world instantly, the below statement will definitely hold true. As I said earlier, whatever physical exercise we do is to ultimately send the appropriate signals to the brain in return for the signals that the brain sends to the body. So when a man exercises his muscles by 'working hard' in the gym, if he does so without concentration them the efficiency of the purpose of the exercise goes down dramatically. But unfortunately most majority of the people do their 'physical exercise' while hearing songs or chatting with friends, or with some other thoughts running in their mind. While this may definitely burn calories but may not develop muscles as it does so when it is done with full concentration. The same holds true for other sports also.
