In the present study, the effects of 8 weeks of low volume high intensity interval training (HIIT) was investigated on circulating diabetes-related cytokines and free fatty acids (FFA) in adults with type 2 diabetes (T2D) and matched controls (CON). Methods: Participants exercised for 8 weeks (3 weekly sessions: 10 x 60 sec HIIT) on a cycle ergometer supervised by medical staff. Prior to the intervention and after the last HIIT session, venous blood samples were collected.Results: Circulating omentin-1 concentrations increased significantly in both the CON-group (p=0.003) and in the T2D-group (p=0.002). Pentraxin-3 (p=0.010) and IL-1ra (p=0.031) levels increased significantly in the CON-group. Plasma FFA in the T2D-group was significantly reduced after 60min (p=0.011). Post HIIT area under curve of circulating FFAs was reduced by -17.73 +/- 6.99% (p=0.041) in the T2D-group. Conclusion: We observed only modest exercise-induced improvements of multiple diabetes-related cytokines. Circulating levels of FFAs were significantly lowered in the T2D-group.
