Four months of supervised endurance exercise training significantly reduces circulating leukocyte counts, particularly effector subtypes (CD4+ Teff, NK cells, neutrophils), in patients with metabolic syndrome.

If you have metabolic syndrome, engaging in supervised endurance exercise for 3-4 months can significantly lower your circulating immune cell counts, specifically those linked to inflammation (effector T cells, NK cells, neutrophils). This benefit occurs regardless of whether you choose moderate continuous training or high-intensity intervals, suggesting consistency and duration are key drivers for immune modulation.
