IJR News — today's news from every sideSprinting Triggers Widespread Blood Protein ShiftsHealth — Aug 21, 2026Short bursts of sprint-interval exercise provoke widespread molecular changes in the bloodstream, altering hundreds of proteins and metabolites immediately and linking these shifts to lower risks of type 2 diabetes, obesity, and cardiovascular disease, with sprinting outperforming steady-state moderate cardio.
