Key Points
- Vigorous exercise, particularly high intensity interval training (HIIT), has unique benefits for brain health.
- Lactate, produced during high intensity exercise, can cross the blood brain barrier and act as a signal for beneficial adaptations in the brain.
- Neurons can use lactate as a preferential energy source, which spares glucose for other important processes.
- Lactate stimulates mitochondrial biogenesis and promotes the production of glutathione, a powerful antioxidant in the brain.
- Lactate acts as a signaling molecule in the brain, increasing the release of neurotransmitters and promoting the production of brain-derived neurotrophic factor (BDNF), which plays a crucial role in neuroplasticity.
- Lactate also acts as a messenger at the blood brain barrier, increasing the production of vascular endothelial growth factor (VEGF) and promoting angiogenesis and repair of damaged blood vessels.
- Vigorous intensity exercise has overall benefits for brain health, including increased blood flow, improved cardiovascular fitness, and the release of neurotransmitters and endorphins.
Summaries
22 word summary
High intensity exercise produces lactate, which benefits brain health by serving as an energy source for neurons and promoting various brain functions.
66 word summary
High intensity exercise, such as HIIT, benefits brain health by producing lactate, which acts as a signaling molecule. Lactate serves as an energy source for neurons, allowing glucose to be used elsewhere in the brain. It also stimulates antioxidant production, promotes mitochondrial biogenesis, angiogenesis, and repair of damaged blood vessels. These effects improve cognitive function and memory, protect against neurodegenerative diseases, and enhance overall brain health.
124 word summary
High intensity exercise, such as high intensity interval training (HIIT), has unique benefits for brain health. This is because lactate, produced during high intensity exercise, acts as a signaling molecule and triggers beneficial adaptations in the brain. Lactate can be used by neurons as an energy source, allowing glucose to be used for other important processes in the brain. It also stimulates the production of glutathione, a powerful antioxidant system, and promotes mitochondrial biogenesis. Lactate acts as a messenger at the blood brain barrier, promoting angiogenesis and repair of damaged blood vessels. These effects contribute to improved cognitive function, enhanced memory, protection against neurodegenerative diseases, and overall brain health. The robust effects on brain health from high intensity exercise are largely attributed to lactate.

High intensity exercise, such as high intensity interval training (HIIT), has unique benefits for brain health. This is due to the production of lactate during high intensity exercise, which acts as a signaling molecule and triggers beneficial adaptations in the brain. Lactate can be used by neurons as a preferential energy source, sparing glucose for other important processes in the brain.
Using lactate as an energy source instead of glucose also allows glucose to be used in the pentose phosphate pathway, which produces glutathione, a powerful antioxidant system in the brain. This is important for normal brain aging and has special relevance for traumatic brain injury (TBI). Infusing TBI patients with sodium lactate has been shown to improve TBI outcomes. Additionally, lactate stimulates mitochondrial biogenesis in the brain and acts as a signaling molecule, triggering the release of neurotransmitters and brain-derived neurotrophic factor (BDNF).
BDNF plays a crucial role in neuroplasticity and promotes the survival, growth, and function of neurons. Higher levels of BDNF have been linked to improved cognitive function, enhanced memory, and protection against neurodegenerative diseases. Lactate also acts as a messenger at the blood brain barrier, promoting angiogenesis and repair of damaged blood vessels. This helps prevent the breakdown of the blood brain barrier, which is a major cause of brain aging and neuroinflammation.
Vigorous intensity exercise, which generates a lot of lactate, has unique benefits for overall brain health. While there are other benefits to high intensity exercise, the robust effects on brain health are largely attributed to lactate. It is important to understand that high intensity exercise leads to substantial adaptations in the brain.
In conclusion, high intensity exercise, particularly HIIT, has unique benefits for brain health due to the production of lactate. Lactate serves as an energy source for neurons, spares glucose for important processes like glutathione production, stimulates mitochondrial biogenesis, and acts as a signaling molecule in the brain and at the blood brain barrier. These effects contribute to improved cognitive function, enhanced memory, protection against neurodegenerative diseases, and overall brain health.

High intensity exercise, such as high intensity interval training (HIIT), has unique benefits for brain health. One of the mechanisms behind this is the production of lactate during high intensity exercise. Lactate is produced in large amounts as a byproduct of the metabolic stress caused by pushing the anaerobic threshold. Lactate can cross the blood brain barrier and act as a signal, triggering beneficial adaptations in the brain.
Lactate can be used by neurons as a preferential energy source, as it takes less energy for mitochondria to use lactate compared to glucose. Neurons are used to using lactate because astrocytes in the brain, which support neurons, produce lactate as a byproduct. Studies have shown that lactate fuels the brain during exercise, and using lactate as an energy source spares glucose, allowing it to be used for other important processes in the brain.
Using lactate as an energy source instead of glucose also frees up glucose to be used in the pentose phosphate pathway, which produces glutathione, one of the most powerful antioxidant systems in the brain. This is important for normal brain aging and has special relevance for traumatic brain injury (TBI), where glutathione is needed the most. Studies have shown that infusing TBI patients with sodium lactate improves TBI outcomes. Additionally, lactate stimulates mitochondrial biogenesis in the brain and acts as a signaling molecule, communicating with the brain and triggering the release of neurotransmitters and brain-derived neurotrophic factor (BDNF).
BDNF promotes the survival, growth, and function of neurons and plays a crucial role in neuroplasticity. Higher levels of BDNF have been linked to improved cognitive function, enhanced memory, and protection against neurodegenerative diseases. Lactate also acts as a messenger at the blood brain barrier, increasing vascular endothelial growth factor (VEGF) to promote angiogenesis and repair damaged blood vessels. This helps prevent the breakdown of the blood brain barrier, which is a major cause of brain aging and neuroinflammation.
Vigorous intensity exercise, which generates a lot of lactate, has unique benefits for overall brain health. While there are other benefits to high intensity exercise that are not exclusive to lactate, such as increased blood flow and neurotransmitter release, the robust effects on brain health are largely attributed to lactate. It is important to understand that high intensity exercise pushes muscles to work extra hard, leading to substantial adaptations in the brain.
In conclusion, high intensity exercise, particularly HIIT, has unique benefits for brain health due to the production of lactate. Lactate serves as an energy source for neurons, spares glucose for important processes like glutathione production, stimulates mitochondrial biogenesis, and acts as a signaling molecule in the brain and at the blood brain barrier. These effects contribute to improved cognitive function, enhanced memory, protection against neurodegenerative diseases, and overall brain health.
