Core Stability Training On College Students' Brain Stem Auditory Evoked Potential And The Impact Of Event Related Potential

Objectives:①To observe the effect of core stability training for a period of sevenweeks on brainstem auditory evoked potentials and event related potentials.②Toevaluate whether the core stability training can enhance vestibulocochlear nervefunction and the ability of attention.Methods: subjects: Twenty healthy female volunteers who are students fromShandong Normal University. Subjects are asked to fill in their basic information andthe PARQ&YOU questionnaire (see Appendix5.1) carefully, and be asked in detailabout their health status. These subjects have no bad habits, neural disease, mentaldisease and cardiovascular system disease, besides, they have normal hearing. So theycan be competent for this experiment. Try to introduce the purpose of this study, andmake they understood what they should pay attention to in the experiment. What ismore, these studies need to ask the written consent of these subjects (informedconsent in Appendix5.5). All the participants are divided into several groups atrandom:①experimental group (n=10): participate in core stability training for sevenweeks at three times per week;②the control group (n=10): The subjects liveaccording to the original style of life without any relevant training. Index experimentmethods:①Using the NDI-092EMG evoked potential instrument electrical nervediagnostic apparatus produced by Shanghai sea god electronic instrument factory toanalyze every index of the brainstem auditory evoked potential (BAEP). In order tokeep impedance at least under5000ohms, I use75%of alcohol on the area where theelectrode is placed to degrease as well as conductive paste to reduce the impedance.According to the international EEG10~20systems, the recording electrode is placedon the top of the head (C); reference electrode placed on the ear (A); the groundelectrode was placed on the forehead (FPz). The short sparse sound stimulation theright ear, and left ear white noise masking. The sound intensity is set to100dB; thesensitivity was5μ V/div; averaging2000; filtering range is set to100Hz-2000Hz,;stimulation frequency is30Hz.②Using the NDI-092EMG evoked potentialinstrument electrical nerve diagnostic apparatus which is produced by the Shanghaisea god electronic instrument factory for recording and analysis of subjects of eventrelated potential (ERP) of each index. Selecting of Ag/AgCI electrode; degreasing theelectrodes placed parts with a concentration of75%ethanol before the test; coatedconductive paste decreased impedance to make the impedance at5000euro.According to the international society of EEG recording electrodes placed in the10/20system, Fz, Cz, Pz; reference electrode placed on the ear of office (A); agrounding electrode at FPz. Using auditory stimulation of Oddball mode,100dBsound stimulus subjects ears, and time is75ms/div; sensitivity is0.5m V/div; filteringrange is1~30Hz; averaging30; stimulation frequency0.7Hz; the target stimulusaccounted for20%; non target stimuli1KHz; target stimulus frequency2KHz,overflow discharge waveform selection.③Using psychological self-rating scale (BFS scale)(see Annex5.3) to test the psychological status of the subjects; using physicalactivity index questionnaire (see Annex5.2) reflect the condition of subjects abouttheir attending weekly physical activity.④Using the body composition analyzer totest the indexes of subjects’ component.⑤Measuring the subjects’ height and weightwith the scale that model for RGZ-120-RT. Results:①the brainstem auditory evokedpotentials in the control group (BAEP) of each index in7weeks without significantchange (P>0.05); each index of brainstem auditory evoked potential (BAEP) of theexperimental group compared with before the experiment, and latency of wave Ⅴsignificantly shortened after4weeks (P<0.05); after7weeks of exercise the latenciesof wave, wave latency, II III-V peak interval was significantly shortened (P<0.05),and Ⅰ-Ⅲ peak interval was significantly prolonged (P<0.05). Compared with fourweeks before, after exercising for seven weeks wave I latency was significantlyshortened (P<0.05);Ⅰ-Ⅲ peak interval was significantly prolonged (P<0.05); Ⅰ-Ⅴ was significantly prolonged (P<0.01); Ⅰ-Ⅰ peak was significantly increased(P<0.05).②In the control group, the event related potentials (ERP) of each indexP300in7weeks without significant change between the experimental group (P>0.05);event related potential (ERP) of each index and P300experiments compared withbefore, was around Cz latency, Fz reaction, Pz latency, Pz reaction time (P<0.05),exercise7weeks after Cz incubation, Fz latency, Fz reaction, Pz reaction, Pz latencywas significantly shortened (P<0.05), and Cz reaction time was significantlyshortened (P<0.01), Fz amplitude was significantly increased (P<0.05). Comparedwith the round, Cz reaction time was significantly shortened (P<0.01), Fz, Fz latencywas significantly shortened reaction time (P<0.05).③The psychological index (BFS)of the control group have no significant changes during the7week (P>0.05); theexperimental group after7weeks of exercise training of core stability, pleasure indexand peace static index increased significantly (P<0.05).④There are no significantdifference in the blood pressure and body index of the control group at7weeks(P>0.05). Compared with the control group, the diastolic blood pressure of theexperimental group is significantly decreased after four weeks (P<0.05). Afterexercising for7weeks, the systolic and diastolic blood pressure are significantlyreduced (P<0.05).Compared with four weeks before, the systolic and diastolic bloodpressure are significantly reduced with exercise for seven weeks (P<0.05).⑤Sevenweeks later, the weight of the control group is significantly decreased (P<0.05), andthe body mass index (BMI) showed significant decrease (P<0.01), after the corestability training for7weeks. The experimental groups body mass index (BMI) aresignificantly decreased (P<0.05), which may be due to climate changes or shortertraining time.Conclusion: The Swiss ball training of core stability with kneeling and lifting armscan significantly improve the attention resource input and response speed and someother cognitive abilities. This training can also significantly improve thevestibulocochlear nerve function, and accelerate its reaction conduction speed.Besides, it can improve your mood and make you feel more pleasure.
