Short Sprints, Big Molecular Shifts: 3 Minutes Reshape Blood Chemistry

Rockefeller University researchers found that six 30-second all-out sprints trigger rapid, widespread changes in blood proteins and metabolites—far more than 90 minutes of moderate cycling—with many affected proteins linked to lower risk of obesity, diabetes, and cardiovascular disease, illustrating how brief, high-intensity bursts can drive powerful interorgan signaling that persists with training.
