Ordered carrier SC500-AF, WOW, what a well built product! I've been a welder/fabricator for over 47 years using all forms of welding processes. I know quality workmanship, this has well designed construction and welding assembly.
But exercise also stimulates brain regions that are involved in memory function to release a chemical called brain-derived neurotrophic factor (BDNF). BDNF rewires memory circuits so they work better.
High intensity exercise is known to have its neuroendocrine role somewhat linked to acidity (including prolactin and growth hormone release) but it appears that buffering the increases in pH with sodium bicarbonate does not modify exercise-induced BDNF increases.
