Lactic Acid Helps Blood Vessels Relax, Could Improve Muscle and Heart Health

A new study in rats shows that lactate, a substance found in the muscles, initiates a cascade of actions in the muscles that helps blood vessels relax. The surprising results are published ahead of print in the journal Function.

Study Reveals How Obesity Could Accelerate Aging in the Brain

A new study conducted in mice traces how obesity and a high-fat diet may accelerate aging in the blood vessels that supply blood to the brain. The work is being presented this week at the American Physiology Summit, the flagship annual meeting of the American Physiological Society.

Breakthrough Omicron COVID-19 Variant Cases Don’t Impair Vascular Health Post-infection in Young Otherwise Healthy Adults

New research finds vaccinated young adults who were diagnosed with COVID-19 during the “omicron wave” of late 2021 and early 2022 did not have lasting vascular impairment after active infection. The first-of-its-kind study is published ahead of print in the American Journal of Physiology-Heart and Circulatory Physiology.

Living near Trees May Prevent Vascular Damage from Pollution

Living near an abundance of green vegetation can offset the negative effects of air pollution on blood vessel health. The first-of-its-kind study is published ahead of print in the American Journal of Physiology-Heart and Circulatory Physiology.

Quick, Frequent Exercise Breaks Improve Blood Vessel Health in Type 2 Diabetes

Frequent exercise breaks during prolonged sitting may be better for blood vessel health in people with type 2 diabetes than less-frequent activity interruptions. The first-of-its-kind study is published ahead of print in the American Journal of Physiology-Heart and Circulatory Physiology.
