Fig. 1From: Ten weeks of high-intensity interval walk training is associated with reduced disease activity and improved innate immune function in older adults with rheumatoid arthritis: a pilot studyNeutrophil migratory changes following high-intensity interval training (HIIT). Neutrophils were migrated toward chemokine (C-X-C motif) ligand CXCL-8 and assessed pre- and post-HIIT for 10 weeks for overall chemotactic accuracy, known as the chemotactic index (a); directional speed, known as chemotaxis (b); and overall speed, known as chemokinesis (c). All data are mean ± SEM (n = 12)Back to article page
