I will pay scant lip service to physicality, as there are many more qualified to comment, although of primary importance i guess are trained muscles, good mechanics hydration of the brain etc.Another good way to suck eggs scrap is to......
You intrestrestingly mention emotion. A highly emotive subject.people such as Schachter-Singer & Cannon- Bard have wasted more trees debating semantics with reductionist theories than any other cul de sac of psychology.
To be deliberately simplistic and start with the idea of the mind/body system (afterall without mind the body is dead, in which case you can then talk purely physical and mechanistic).Emotion can be trained.I would argue must be trained along with the body.
To try and answer your question instead of listing random thoughts,I shall part quote a psychologist with whom i share many views.
To be read with boxing in mind/body..S.Keleman:"Emotional anatomy is layers of skin, muscles, bones,hormones etc as well as the organisation of experience" "Emotions and feelings follow the rules of water.When we we brace ourselves for shock or blow or when we harden to confine pain, our liquid state is like ice...No one is fixed in concrete;rather some processes are ice or bone-like and others are more fluid".He did not write this with boxing in mind/body,but I think it answers some of the knockout question?.
How to train the liquid state via the mind and to what degree is it possible? .I may attempt that dependant on replies and an ice pack on my index finger.
