The Influence on Immune Cells by Aerobic Exercise and Detraining

Abstract

With 14 college students as the research object, Were randomly divided into detraining group (group D) and aerobic exercise group (group A),D group stop training after 4 weeks’ training, A group training eight weeks, to observe their effects on the immune system function. Found at the beginning of exercise, A group and D group all inhibition, restored gradually at the fourth week, group A is more obvious than group D. Detraining 2 weeks, each index has returned to normal, according to the experiment 2 weeks is the optimal time for detraining. Introduction Aerobic exercise is human body under the situation of physical exercise in which the oxygen supply fully, in the process of exercise, the human body equals the demand for oxygen and oxygen inhalation, oxygen to reach the equilibrium state, include some of low intensity, long time exercise, such as: walking, jogging, setting-up exercise, power bicycle, etc[1].The persistence of the long-term aerobic exercise can effectively improve cardiovascular and pulmonary function, increase the amount of Hb in the body, improve body resistance, anti-aging, enhance the working efficiency of the cerebral cortex, increase the consumption of fat, prevent arterial sclerosis, reduce the incidence of disease of heart head blood-vessel, etc. This article research on 14 freshman who study in Xi’an physical university, by aerobic endurance training, testing the body’s immune cells changes in different movement period, provide aerobic exercise to improve the body quality, provides the theory basis for improving immunity in further, to deeply understand the effect of aerobic exercise to the body’s immune system to lay the theoretical foundation. Research contents and methods Research object. 14 male students in grande one inhuman movement science in Xi’an physical university, mean age 19.5±0.7years, average height of1.75±08m, an average of 64.40±3.35 kg weight, healthy and without any professional sports training, were randomly divided into having group (group D) and aerobic exercise group (group A). Training arrangement. The students have aerobic exercise by treadmill(9 km · h 1, grade 0) for 45 minutes, a total of eight weeks, the have aerobics exercise every other day. Testing schedule. At 0, 4, 6, 8 weeks after the weekend aerobic exercise 1 hour take blood, every boy take venous blood 5 ml, separation of serum, standby testing relevant indicators of immune function. Testing index. WBC count, GRAN count, GRAN%,LYMPH count, LYMPH%,MID count, MID%. Data processing. all the data using the mean and standard deviation x ±s, by statistical software SPSS, significant differences P<0.005. Experimental results Form table 1, the total number of in WBC, GRAN, LYMPH, MID in A group decreased obviously (p<0.01),compared the sixth week to the zero week GRAN have very significant difference (p< 0.01), compared to the zero week, the WBC had significant difference (p<0.05), compared with the sixth week and the fourth week, the total number of WBC, LYMPH, MID International Conference on Education Technology, Management and Humanities Science (ETMHS 2015) © 2015. The authors Published by Atlantis Press 294 significantly increased(p < 0.01);Compared to the eighth week and the zero week, in addition to the total number of WBC has significant difference(p< 0.05), and other indexes have no obvious change, compared the eighth week with the fourth week, the total number of WBC, LYMPH, MID significantly increased(p<0.01);In group D, compared the fourth week to the zero week, the total number of in WBC, GRAN, LYMPH, MID decreased obviously(p< 0.01),compared the sixth week to the zero week, alough every indexs have changes, but have no significant difference; compared with the sixth week and the fourth week, the total number of WBC,GRAN, LYMPH, MID significantly increased(p<0.01);compared with the eighth week and the fourth week, the total number of WBC,GRAN, LYMPH, MID significantly increased(p< 0.01).Compared to group A and Group D, in the fourth week and the eighth week, there have no significant difference, in the sixth week, WBC and LYMPH have significant difference(p<0.05),GRAN have a very significant difference(p<0.01).
