Abstract

Objective: Physical exercise contributes to improving stability against nerve injury caused by ischaemic stroke. Here we aimed to preliminarily investigate the effects of continuous endurance training (CET) and high-intensity interval training (HIT) on stroke-associated anxiety, locomotion, neurological assessments and P70S6 Kinase (P70S6K) activation as well. To do this, rats were trained according to HIT and CET protocols for 2 months prior to being subject to middle cerebral artery occlusion surgery. Methods: Twenty-four hours later behavioural examination was performed by elevated plus maze (EPM) testing, open field and neurological scoring followed by cortical and hippocampal P70S6Ks immunoblotting. Results: According to the obtained data pre-ischaemic HIT and CET similarly improved neurological performance, anxiety levels and locomotion in EPM and open field tests following ischaemic stroke while there was a remarkable rise in hippocampal and cortical P70S6K activation in the HIT group compared to the CET counterparts. Conclusion: Behavioral and molecular data suggest that interval training is more beneficial rather than CET, but the distinct mechanisms of CET and HIT on memory are still topics to be discovered. © 2017 Taylor & Francis Group, LLC.
