Vigorous exercise stimulates lactate production in muscles, which travels to the brain and triggers the production of neurotransmitters like serotonin and norepinephrine.

“High-intensity exercise increased serotonin, which correlated with improved inhibitory control - the ability to selectively focus and suppress attention to other stimuli.”

“High-intensity exercise increases lactate - which is transported into the brain and increases serotonin.”

“High-intensity exercise increased serotonin in young adults, which correlated with improved inhibitory control - the ability to selectively focus and suppress attention to other stimuli.”

“Vigorous exercise forces your muscles to release lactate, which acts as a messenger to your brain, signaling the production of serotonin. This not only boosts your mood but also plays a crucial role in enhancing motivation by regulating self-control and improving selective attention and cognitive inhibition.”

“High-intensity exercise causes muscles to produce lactate which gets into the brain where it plays a direct role in the production of norepinephrine & serotonin.”

“Vigorous exercise forces the muscles to produce lactate, which then travels to the brain, triggering the production of key neurotransmitters like serotonin and norepinephrine.”

“Norepinephrine and serotonin, produced during (especially vigorous) exercise, boost focus, attention, motivation, and mood for several hours or more post-workout.”

“Studies have found that people that exercise produce a lot of lactate this correlates with an increased in serotonin which also correlated with improved impulse control”

“and so lactate is fueling that your brain function during exercise but it's also increasing things like norepinephrine which is involved in focus and attention serotonin”

“And in fact, individuals that were doing the vigorous intensity exercise had higher serotonin and they had more they had better impulse control. So they had basically improved what's called inhibitory control.”

“We also know that lactate itself signals to the brain to make neurotransmitters. We have human data on this. both serotonin. Most people think about serotonin as that neurotransmitter involved in mood, makes you feel good. It's also involved in executive function and more importantly impulse control. Um, and I talked about all those studies showing that vigorous intensity exercise has a pretty profound effect on impulse control. Well, there have been human studies that have done dose dependent um, exercise protocols where people do light exercise, moderate intensity, or they do vigorous intensity exercise. And it's the vigorous intensity exercise that increases lactate the most. And that's also associate associated with the most impulse control. We want impulse control. We want to be able to be focused and norepinephrine as well.”
