Interesting,
I definitely believe there are many positives for using such techniques! And I have to agree cow with the CNS burnout (I have never tested it scientifically, or had the means to unfortunately). I belive it to relate to stress, granted there arer varying types of stress, eustress being positive, distress being negative!
I remember as a teenager when I began lifting, the immense pressure I put upon myself to gain, particularly in squats, I began to put so much pressure on myself i would be thinking about squatting days before I had to. I got to the point where I begain to dread my sessions, the mental rehearsals, anticipation and anxiety began to build and build, to the point where I no longer gained and began to overtrain.
Now this is my opinion, not scientific fact, but I believe stress to be one of the biggest killers of gains. the pressure we place on ourselves at work, home and in the gym (physically and emotionally) can have a negative impact on training. Remember emotional arousal (not that kind, thick!!!) has a physiological response!! and I'm sure everyone knows what cortisol is?
So, emotional arousal, psyching up and any other methodologies that induce a physiological stress response (fight or flight) can have a negative impact on training, Want to know if your stressed heres some info Ive cut and pasted you may like to read:
A brief list of signs would include:
Psychophysiological responses--muscles tight or aching, nervous tics like in the eyelid, hands unsteady, restlessness, touching yourself repeatedly, clearing your throat, frequent colds, pain, upset stomach, sweating, skin problem or itch, stiff posture, holding things tightly, strong startle response, headaches, high blood pressure, ulcers, heart disease, colitis, hemorrhoids, rashes, diarrhea, or frequent urination. These are somatoform disorders.
Behavioural-emotional signs--hyperactivity, walking or talking faster, in a hurry, irritation with delays, panicky, blushing, getting tongue-tangled, avoiding people, nervous habits (strumming fingers, eating, smoking, drinking), changing habits (becoming less or more organized), poor memory, confusion, stumbling over words, inattentiveness, excessive worrying, preoccupation with a certain situation, holding a grudge, irritability, crying, obsessive thoughts, compulsive actions, outbursts of emotions, bad dreams, apathy, etc. These are anxiety reactions.
Tiredness and lack of energy--general lack of interest, bored, watching TV and falling asleep, humourless, sleeping a lot, insomnia, can't get going, sighing, and moving slowly. (Or, sometimes, too much energy, as mentioned above.)
Anxiety intrudes on our consciousness or cognition in many ways: excessive preoccupation with the threatening person or situation, a desperate striving to understand why someone behaved the way they did, repeatedly obsessing about the upsetting event, unstoppable pangs of emotion (loss, anger, jealousy, guilt, longing, etc.), excessive vigilance and startle reactions, insomnia and bad dreams, aches and pains and other unwanted sensations. Plus all the words mentioned above in the introduction that reflect the subjective feelings we have, including nervous, up tight, scared, apprehensive, etc.
, In a future post (when I get a little more time!) I'll discuss ways of safely and effectively preparig your mind.
Cow and everyone else, thanks for the input!!!
