High Intensity Interval Training (HIIT) Exercise Changes Brain Activity: Effects on Dopamine D2 Receptors & Mu Opioid Receptors (2024 Study)

High-intensity exercise (HIIE) leads to significant changes in brain activity, specifically in regions linked to dopaminergic and μ-opioidergic neurotransmission, which are associated with a mood boost. Highlights: Positive Mood Effects: Both low- and high-intensity exercise increased positive affect, as measured by the PANAS Positive Affect scale. Brain Activity Changes: HIIE resulted in significant decreases in …

Hypertension Linked to Impaired Cognition & Gait in Older Adults (2024 Study)

Hypertension in older adults leads to poorer cognitive and walking performance due to the need for more brain resources to manage dual tasks. Highlights: Older adults with hypertension show higher brain activation in motor and sensory areas when performing dual cognitive-walking tasks compared to healthy peers. Hypertensive individuals have worse cognitive performance on single cognitive …

Antidepressant Mechanisms of Aerobic Exercise (2024 Review)

Aerobic exercise reduces depressive symptoms by decreasing inflammation, boosting dopamine transmission, and enhancing motivation and cognitive control. Highlights: Depression & Dopamine: Depression is linked to disrupted dopamine transmission, affecting reward processing and motivation, particularly in effort-based decision-making. Inflammation’s Role: Exercise reduces systemic inflammation, which otherwise impairs dopamine transmission and contributes to depressive symptoms like anhedonia …
