Researchers proved pooping before exercise improves cognitive and athletic performance by 10-14%. they tested 13 elite triathletes using the Stroop test to measure executive function and reaction times. the results are insane: → regular completion time: 27.1 seconds → after voluntary defecation: 24.4 seconds (10% faster) → after magnesium-induced defecation: 23.4 seconds (14% faster, with 100% of participants improving) interestingly, near-infrared spectroscopy showed no relevant changes in the prefrontal cortex. instead, greater oxygen consumption was tracked in the subumbilical (lower abdominal) region during the cognitive test post-defecation. meaning what? the state of your rectum acutely influences cognitive efficiency through local pressure and metabolism. constipation literally makes you slower. peak mental performance requires clearing out the cache first..
