Why do you lose arm strength when the forehead is covered?
I was attending this workshop, in which the speaker was giving this demonstration in order to make her point:
1) First, the male participant was asked to extend his arm out, perpendicular to the floor, and hold it as firmly as he could. She would push the arm down, but it was very difficult if not impossible to do so.
2) In the second round, in addition to having the participant extend out his arm, she covered his forehead with her hand (almost pushing against his forehead, I later learned from him.) Now, it was easy for her to push his arm down.
3) Her explanation: Forehead is one’s energy center; covering it blocks energy circulation, therefore one loses part of one’s strength.
What kind of -ology is this?
Are there scientific explanations for this?
Thank you very much for any help.
