Exercise Intensity Rewires Interorgan Communication, Boosting Cardiometabolic Health

Exercise intensity modulates interorgan communication and is associated with

A new study in Cell Reports Medicine reveals that sprint-interval exercise (SIE) triggers far greater changes in circulating proteins and metabolites than moderate-intensity exercise (MIE), reshaping how organs communicate. By analyzing plasma from untrained and trained participants, researchers mapped these intensity-dependent signals to their tissues of origin and destination, identifying proteins linked to cardiometabolic protection. The findings suggest that even brief, high-intensity exercise may offer unique health benefits through distinct molecular pathways.
