motor learning activated by stressor – speed, to adapt to the stressor,result is speed and performance when in speed

i assume it goes both ways and e.g. Zen meditation will slow onedown, also depresion/LH/static job

possible treatment -external speed (treadmill),external speed  /pulse measurement

————————–

I speculate that high intensity over continues period of time develops (up regulate) dopamine secretion. that includes brain games
