Exercise-Induced Changes in Serum Oncostatin M Levels in Recreationally Active Males

The aim of this study was to compare the effects of workload-matched acute moderate-intensity continuous exercise (MICE) and high-intensity interval exercise (HIIE) on serum OSM levels on a cycle ergometer in recreationally active, healthy men. Fifteen participants participated in both MICE and HIIE sessions. The HIIE session consisted of 10 x 1 min intervals at 90% of maximal oxygen uptake (VO2max) separated by a 75-second active recovery period at 60 W, whereas the MICE session consisted of a \~21 min exercise session at 55% of VO2max. Blood samples were collected before (Pre) and immediately after (Post) acute MICE and HIIE sessions. Serum OSM levels were measured by the ELISA method.
