Aim: we investigated the effects of six weeks of HIIT and curcumin supplementation on hepatic cellular death and also GSH level in male rats exposed to drinking water arsenic.Methods: 48 rats were randomized in six groups including HIIT, curcumin, HIIT+curcumin, arsenic, ethanol control and normal control. Arsenic 5 mg/bw.day and curcumin 15 mg/bw.day, were consumed orally for entire the study period. HIIT were conducted for six weeks (5 d/w, 60 min/session (with 4 min running at 85-90% of Vo2max and 2 min recovery at 50-60% of Vo2max intervals). Results: Arsenic exposure down regulated hepatic CK18 M65 level and also in a lesser extent; the cellular GSH content. Curcumin supplementation either alone or concomitantly with HIIT, could reverse the changes in hepatic CK18 M65 level. However; only in the HIIT+curcumin group, a remarkable elevation of hepatic GSH level was observed. Conclusion: Arsenic exposure renders liver to an increased oxidative stress and apoptosis level and the both HIIT and curcumin supplementation have appreciable effects to neutralize these hazardous effects. Moreover, only the synergistic effect of HIIT and curcumin supplementation could attenuate the liver antioxidants following arsenic exposure. However, more investigations remains to be done because of the study limitations and lack of similar evidence in this area.
