| Background: Over the years, the face of tens of thousands of nerve cells, the researchers often can not start, the production evoked potential technique for the study of cognitive psychology provides a useful approach. Evoked potentials of the nervous system to accept, the external stimuli generated by a specific electrical activity, can be divided into exogenous and endogenous stimuli stimulus-related potentials related potentials. Visual evoked potential (VEP) is an exogenous stimulus related potentials, brain occipital visual cortex to visual stimulation (flash or graphic stimuli) the reaction of the cluster signal is a reflection of the visual organ, the visual transmission Road, the visual center the functional status of an important indicator of neurophysiology. Objective: This study was based on the use of EEG Indexes of neurophysiology intermittent exercise on cognitive function and its mechanism was investigated beverage supplement on the negative impact caused the prevention and treatment of cognitive function, observed under quiet, both before and after aerobic exercise drink supplement state and visual evoked potentials before and after the visual event related potential changes.Methods: In this paper, the literature, observation, investigation, experiment, statistics and other research methods. Experimental determination of the following indicators:â‘ visual evoked potential test: The Poseidon Shanghai Medical Electronic Instrument Factory production NDI-200 (Poseidon) were recorded nerve examination and analysis of patient volunteers in the box under the stimulation of visual evoked potential.Observed indicators for the N75, P100, N145 latency and amplitude.â‘¡visual event-related potential test: The Poseidon Shanghai Medical Electronic Instrument Factory production NDI-200 (Poseidon) nerve were recorded before and after exercise Detection and Diagnosis of visual event-related powerResults:â‘ different time resting state VEP and ERP testing, each index between the three measurements there was no significant difference (P>0.05), retest correlation coefficient was between 0.84-0.97.â‘¡different intensities of aerobic exercise on VEP (P100 latency change in the most obvious) and the ERP effects: Compared with the resting state, anaerobic threshold intensity in the past immediately after exercise, P100 latency was significant that showed reduced (P<0.01), anaerobic threshold intensity exercise to be nearly restored the body temperature remained significantly reduced (P=0.059); near maximal intensity immediately after aerobic exercise significantly reduced (P<0.05), near maximal intensity exercise remains to be recovered temperature significantly shorter (P<0.05). Anaerobic threshold intensity aerobic exercise almost immediately after, and maximal intensity exercise almost immediately after the P100 latency there was no significant difference between (P>0.05). More quiet state, near the anaerobic threshold intensity immediately after exercise P300 latency, reaction time significantly shortened (P<0.05). Anaerobic threshold intensity exercise to be nearly restored the body temperature, maximal intensity exercise almost immediately after, near maximal intensity exercise until body temperature returned to P300 amplitude were not produced after significant difference; P300 latency and amplitude is consistent with trends that the anaerobic threshold intensity exercise almost immediately after the shortest P300 latency and amplitude of the longest.â‘¢quiet drink supplement on the state of VEP and ERP: drinking pure water (placebo), the drink before, immediately after drinking, drinking 20 minutes after the P300 amplitude and latency were also no significant changes (P>0.05). Drinking, and drinking than before, and immediately after drinking alcohol for 20 minutes after the P300 latency significantly longer (P<0.05), amplitude was significantly lower (P<0.05). After a variety of sports drinks to add visual evoked potential N75 latency, amplitude, P100 latency, N145 latency and amplitude did not produce significant changes, but added Kang Bite sports drink (orange flavor) immediately after, 20 minutes after the supplement before the P100 amplitudes was significant increase (P<0.01); Added Kang Bite sports drinks (peach flavor) P100 amplitudes after the 20 minutes before the very significant additional increase (P<0.01).â‘£sports drink supplementation on aerobic exercise of VEP and ERP: whether or not to add sports drinks, compared with the resting state before exercise, near maximal intensity exercise that is presented immediately after the P100 latency significantly shorter (P<0.05) ; Compared with the resting state, anaerobic threshold intensity exercise almost immediately after the control of the tendency to increase P100 latency, beverages supplemented group (mineral water, sports drinks (orange flavor) test, sports drinks (peach flavor)) in P100 latency significantly shorter (P<0.05); And near anaerobic threshold intensity exercise compared to the amount of near-polar intensity exercise sports drink (orange flavor) P100 latency was significantly shortened (P<0.05), while the P100 latency of the mineral water group was significant shorter (P<0.01). Compared with the resting state, the control group, add mineral water group, P100 amplitude with the increase of exercise intensity first increased and then decreased; supplement sports drink (orange flavor) after increased P100 amplitude, near maximal intensity exercise demonstrated a significant difference (P<0.05); Added sports drinks (peach flavor), the anaerobic threshold intensity exercise almost immediately after the P100 amplitude increased significantly (P<0.05). Four tests, P300 latency in the near anaerobic threshold intensity immediately after exercise, near maximal intensity immediately after exercise was decreasing, sports drinks (orange flavor) test under the more quiet, almost immediately after the anaerobic threshold intensity exercise was significantly shorter seems (P=0.065); P300 amplitude did not significantly change; reaction time was also shortened trend.Conclusion:â‘ different intensity aerobic exercise can make the latency of visual evoked potential indexes significantly reduced. Movement is independent of the temperature effect on the P100 latency of one of the factors, P100 latency has a certain sensitivity to the movement, but the change does not exercise intensity increases with the increase, that there is no compliance with exercise intensity. Aerobic exercise the ERP P300 latency and reaction time were significantly reduced,the results can show the best in terms of cognitive exercise intensity may be close to the anaerobic threshold intensity.â‘¡quiet state VEP indexes added coffee had no effect, and added immediately after, 20 minutes after the ERP P300 latency significantly prolonged and amplitude decreased significantly; supplement drink VEP P100 latency significantly prolonged, while the ERP P300 latency significantly reduced; Wine and coffee on the VEP and ERP did not have any impact, add wine and coffee immediately after, 20 minutes after the reaction time significantly extended. Description Although coffee has some sobering effect, and can not offset the other elements of alcohol on reaction time (such as nerve conduction velocity) of the inhibition. Kang Bite sports drinks added after VEP P100 amplitude was significantly increased, no effect on other indicators.â‘¢sports drink supplementation on aerobic exercise VEP P100 amplitude of the most obvious, is not added beverages, along with increased exercise intensity, P100 amplitude is first increased and then drop down"U"type features, or nearly anaerobic threshold intensity after exercise compared with resting state increased slightly, while nearly maximal intensity exercise then decreased, even lower than the resting level. Subjects in the water saturation, the additional volatility of mineral water and when the P100 is not added when the change is consistent, and added after the two sports drinks have shown the P100 amplitude significantly increased (P<0.05). Illustrate this change is not caused by dehydration, sports drinks may be a relationship of certain substances. |
