The Influence Of Brain's Function Of A Single Session Acute Aerobic Exercise

Objective:To characterize potential effects in brain function after a single session acute aerobic exercise.Methods: We selected 27 healthy adult volunteers according to the inclusion criteria.All participants completed informed consent prior to the start of the experiment.Pre-exercise brain magnetic resonance imaging was performed on each subject,including T2 WI,T13D and fMRI.The subjects then performed a second scan identical to the first one immediately after 20 minutes of moderate aerobic exercise.The resulting data was processed and analyzed based on the software running under Matlab2014b(Math Works,Natick,MA,USA).The software includes SPM12 software package,REST 1.8 software package and DPARSF 4.1 software,a rest state data processing assistant.The changes of fALFF in whole brain area before and after exercise were analyzed further.Results: After a single acute aerobic exercise,the fALFF value in the parahippocampus and the superior temporal gyrus increased significantly,while the value of fAFLL in the superior parietal gyrus decreased;the center degree and the efficiency of the whole network node of superior temporal gyrus,Cuneus_R,Lingual_R and Parietal_Inf_R increased,and the The local network efficiency of hippocampus,Lingual_R and Parietal_Inf_R increased.There was no significant difference in total net efficiency and small-world attributes between volunteers before and after a single acute aerobic exercise.Conclusion : A single acute aerobic exercise can prove the activity of the hippocampus and related brain areas and the superior parietal gyrus enhancement of the network connectivity from the aspects of local brain function and brain network connectivity;after exercise,there was no significant difference in the global brain level.
