Sport hypnosis - mental toughness

Flash,
I am not talking about mental toughtness, far from it, and I read Speed Trap quite a few times. I was talking about mind-body connection, which is nothing esoteric, nothing New Age, but a field to be explored. This is for the advancement of knowledge.
Electricity in medicine was dismissed a century or more ago. Then, we had Robert Becker among others and then we had EMS, ARP, Tens, microcurrent, cold laser and so on. Mind-body connection is a field to be further explored and I want to repeat, I’m not referring to mental toughness. I’am talking about adaptations to internal and not external stimuli. And it is nothing esoteric, not tallking about mystics, faith-healers, fatima or medjugorie. Thanks.
I can also suggest some interesting research.
