| Objective: study the visual evoked potential is brain occipital lobe visual cortex of visual stimuli (flash or graphics stimulate) happening reaction cluster of electrical signals, which is a reflection of the visual organs, visual transmission path, visual central function condition of important neurophysiology indexes. The event related potential means that when people to give to the particular stimulus cognitive processing (such as: attention, memory, thinking) from scalp surface recorded by the brain potentials, which reflects the cognitive process of neural electrophysiology midbrain change, so someone called this is "cognitive potentials. Previous studies showed different sports of visual evoked potentials and events related potential effects of different. Mani tactic and yoga completely good health qigong breathing is meditation class two different expressions, is a kind of things in two different regional natic culture of the emergence and development results. This paper adopts visual evoked potential this reflect visual organs, visual transmission path, visual central function condition of important neurophysiology index and the reflection of cognitive function P300 "window", both horizontal and vertical observation subjects for 16 weeks of mani tactic and completely breathing exercises instantly, and after different time visual evoked potentials and events related potential changes, discussions on Saturday word tactic and 16 completely breathing exercises to visual evoked potentials and cognitive function influence rule. Research object: select shandong normal university students science college undergraduate girl 25 human subjects, all participants were randomly divided into (1) the experiment group (n = 9) : conducts weekly five times, each time 30min, for 16 Saturday word tactic exercise. 2 experimental two groups (n = 9) : conducts weekly five times, each time for 16 weeks 30min, completely breathing exercise. 3 the control group (n = 7) : no regular physical activity, the original regular life life. Methods: respectively by means of literature and observation investigation method, experimental method and so on many kinds of research methods. The index test: (1) visual evoked potential test: adopt NDI - 200 (Poseidon number) neural electric inspection diagnosis instrument log analysis subjects squares (25 x 25) stimulation patterns flip mm~2 visual evoked potential. Visual evoked potential record selected head bipolar guide coupon, stimulating frequency for 2Hz, brightness for 90cd/m~2, contrast for 80%, filtering scope for 1Hz - 100Hz, sensitivity for 10 mu v, stacked 100 times. Observing indexes for N75, P100, N145 incubation period and fluctuation. (2) event related potential test: by Shanghai Poseidon medical electronic instrument factory production NDI - 200 (Poseidon number) neural electric inspection diagnosis instrument record visual event related potential, adopt the peculiar test induced P300 wave, exciting means for visual stimulation. Target stimulus for black and white shaft poles (25x275mm), appear likely to 20%. Non-target stimulus for black and white squares (25x25mm), appear likely to 80%. Target stimulate superposition 30 times. (3) other health index test: Body Composition tests USES the south Korean VIVENTE Body there in Analyzer Body Composition Analyzer record biooxyrate exercise before and after the Body Composition, Quiet lung function and exercise lung function USES German and lattice CPX movement MasterScreen cardiopulmonary functional testing system record. The determination of blood pressure using mercury sphygmomanometer column type of quiet when measuring blood pressure, The determination of PiChe breathing sent by measuring, as the largest inhale bust value with the biggest breathing bust value difference. Results: (1) a mani mantra acute exercise before and after travelling respectively visual evoked potential and events related potential are no significant difference (P > 0.05). 2 once before and after acute mani tactic exercise has shortened trend P100 latency, but not to the significant difference, Completely breathing exercises before and after exercise VEP each index all did not change significantly. (3), compared with before taking exercise once acute mani tactic after exercise P300 preclinical significant shortened (P < 0.05), reaction when also decrease, but not to the significant difference, Once the acute completely breathing exercises after incubation period shorter, response in P300 significantly lower (P < 0.05). 4 for 16 weeks of mani tactic group in the process of exercise P100 latency and amplitude with exercise time increases a gradually shortened trend, 16 weeks after incubation period is the shortest, volatility extremely significant shorter than before taking exercise value (P < 0.01), For 16 weeks of completely breathing group in the process of exercise, subjects' P100 latency and amplitude and exercise before were significantly shorten compared the trend, exercise 10 weeks later reach the level of significance (P < 0.05), and amplitude is also extremely significant shorter than before taking exercise numerical (P < 0.01). Exercise 16 weeks later, incubation period and amplitude values have rebounded, The control group visual evoked potential each incubation period and amplitude four times between data there are no significant difference (P > 0.05). Mani tactic group in 16 will5 Saturday word tactic in the process of exercise is shorten trend, P300 preclinical exercise 5 weeks later than before taking exercise is very significant sexual shorten compared (P < 0.01), exercise more exercise before 16 weeks after compared showed extremely significant shortened (P < 0.01). Response also presents the shorten trend, but not to the significant difference, Completely breathing group in 16 weeks completely breathing in the process of exercise, although in P300 preclinical shorten trend, but the difference was not significant meaning, P300 volatility has increased trends, and in the exercise 10 weeks after compared with before taking exercise increased significantly (P < 0.05), the overall response in exercise 10 weeks after compared with exercise before presenting significant shortened (P < 0.05), and exercise for 16 weeks after 10 weeks after compared with exercise were significantly prolong (P < 0.05). There are no significant differences in the control group. 6 mani tactic group in the exercise 5 weeks later diastolic blood pressure and systolic blood pressure has significantly lower (P < 0.05), and exercise for 16 weeks after diastolic pressure very significantly lower (P < 0.01), breathing the difference in exercise for 16 weeks appearing after significantly increased (P < 0.05). 16 weeks completely breathing group exercise diastolic blood pressure and systolic blood pressure it is increasing, including systolic blood pressure in exercise 10 weeks appear significantly increased (P < 0.05), breathing the difference in exercise period also shows ascendant trend, compared with before taking exercise 5 weeks later and 16 weeks after all appear significantly increased (P < 0.05). The control group in both before and after exercise no significant differences. 7 for 16 weeks training, mani tactic group tide volume (VT) declined, the largest sports load (LOADmax) and exercise duration (Tmax) presented significant difference; Completely breathing group tide volume (VT) shows ascendant trend, but failed to meet significant difference, the maximum amount suction oxygen peak (O2peak), lung ventilation volume (VEmax) and sports duration (both Tmax) were significantly increased, The control group did not see significant differences. 7 three groups of participants' body composition appeared basic same trend of significant differences. Conclusion: (1) a acute exercise, and visual evoked potentials, compared to the event related potential mani tactic and completely breathing this kind of low intensity meditation movement sensitivity stronger; Mani tactic and completely between breathing exercises and no significant differences. 2 for 16 weeks of mani tactic and completely breathing exercises can significantly improve the participants' health level, performance for body weight, body fat rate, lower blood pressure, breathing, and poor increase can effectively improve lung function. (3) engaged in mani tactic exercise can shorten subjects to external stimuli information processing speed, performance for P300 preclinical markedly shortened; Engaged in completely breathing exercise makes the subjects to a given stimulate investment focus resources increase, thus make the motor output, manuela martins-green for P300 volatility increases, the overall response shortened. Sino-foreign these two kinds of meditation movement has his merits. |
