通过连续观察皮艇运动员血清免疫球蛋白IgA、IgG、IgM以及补体C3、C4对运动训练的应答特征,揭示长期、系统从事皮艇专项训练对人体体液免疫的影响。以河北省皮艇队25名运动员为实验对象,其中二级运动员12人,一级以上运动员13人(含一级)。自冬训第一周开始,连续17周跟踪记录血清IgA、IgG、IgM以及补体C3、C4值。结果发现:大部分免疫指标值时常低于临床正常值,且训练年限较长者相对更低;训练负荷的变化对各项免疫指标均有不同程度的影响,IgG及补体C3变化最为显著。大强度训练周及测验周后免疫指标下降显著,进入调整周后缓慢回升。  相似文献

通过评价优秀赛艇运动员免疫机能对模拟专项比赛负荷的应答性反应与恢复特征,为运动员免疫功能的调理提供科学依据.结果发现:(1)优秀运动员安静状态时的免疫指标明显低于正常值,表明经过长期的大强度专业训练,运动员的免疫功能明显降低;(2)在赛后即刻,白细胞总数及各亚类均显著升高,但各亚类升幅不等;(3)赛后3h,淋巴细胞、中间细胞、免疫球蛋白与补体水平均显著下降并接近或达到运动前水平,但中性粒细胞则逆势大幅度上升,白细胞总数略有降低,各亚类再次显著改变;(4)赛后24h,绝大多数免疫指标均已基本恢复至赛前水平,但中间细胞、淋巴细胞与C4却在赛后3 h已恢复的基础上发生程度不等的回升,可能与白细胞3种亚类各自的移行方向、生物学作用及调节机制不同有关.  相似文献

为了了解我国优秀速滑运动员赛前阶段的机体免疫情况。对齐齐哈尔市冬季运动项目管理中心速滑队的8名女子1500m项目运动员赛前训练阶段的IgG、IgM、IgA及IL-2、IL-6的水平进行测定。结果显示,IgM在赛前第二周下降可能与IL-2的降低、皮质醇的升高有关。sIL-2R浓度的升高中和活化了的T淋巴细胞周围的IL-2,降低IL-2介导的免疫反应,使T淋巴细胞逐渐静息,导致机体免疫功能受到抑制。处于应激状态的特定环境之中,以及免疫功能失调均可使IL-6的分泌水平升高;从肌源性IL-6的角度分析,IL-6的逐渐升高也可能与速滑运动员的运动负荷增加和滑行的肌肉收缩方式有关。皮质醇含量逐渐上升,可能与调控IL-2降低其水平有关。  相似文献

通过对广东省田径队参加“2000年全国田径锦标赛”优秀短跨项目运动员四周大强度训练和比赛的跟踪调查,观察大强度长时间训练和比赛对其机体B淋巴细胞免疫系统功能的影响。结果显示:长时间大强度训练对高水平田径运动员免疫球蛋白IgA、IgG、IgM影响不大,但IgG始终低于正常水平,呈显著性差异(P<0.05);整个训练和比赛中,唾液分泌型免疫球蛋白(SIgA)呈现对抗原刺激后的增加,训练后与正常值比较有显著性差异(P<0.05),比赛后与正常值比较,有非常显著性差异(P<0.01)。结果提示:高水平田径短跨项目运动员赛前大强度长时间训练不会对血清免疫球蛋白含量产生太大影响,但唾液SIgA则会显著性升高,表明黏膜免疫系统功能良好,不存在“开窗现象”。以上结果可能与训练水平或良好的心理应激状态有关。  相似文献

目的:研究3周模拟LoHi对自行车运动员免疫功能的影响。方法:8名男性自行车运动员进行3周模拟LoHi,监测T淋巴细胞亚群、NK细胞、免疫球蛋白和白细胞的变化情况。结果:训练1周各指标无显著变化;训练后2周CD4和CD4/CDs下降,NK细胞活性增加,白细胞总数和淋巴细胞数量先增加后持续下降。结论:LoHi 1周不会影响机体的免疫功能,但是3周的LoHi及随后2周的常规训练可使机体的免疫功能开始出现下降趋势;LoHi监控过程中血清免疫球蛋白的有效性较差;白细胞总数和淋巴细胞数量对LoHi监控具有重要意义。  相似文献

This review will examine the effects of exercise and training on immune func-tion and will discuss the methodological problems that limit the interpretation of many exercise immunology studies. Acute bouts of exercise cause a tempo-rary depression of various aspects of immune function, such as neutrophil oxidative burst, lymphocyte proliferation, monocyte MHC class II expression, and natural killer cell cytotoxic activity, that will usually last for approximately three to 24 hours after exercise, depending on the intensity and duration of the exercise bout. Post-exercise immune function depression is most pronounced when the exercise is continuous, prolonged (<1.5 hours), of moderate to high intensity (55-75% VO2max), and performed without food intake. Periods of intensified training that result in overreaching have been shown to chronically depress immune function—i.e., immune cell functions measured at rest are still depressed 24 hours after the last exercise bout. Although elite athletes are not clinically immune deficient, it is possible that the combined effects of small changes in several immune parameters may compromise resistance to common minor illnesses such as upper respiratory tract infection. Protracted immune depression linked with prolonged training may determine susceptibility to infection, particularly at times of major competitions.  相似文献

In this study, we assessed the effects of a 4 week basic military physical training programme for male recruits of the Hellenic Air Force on the number and distribution of circulating immune cells and adrenergic and adrenocortical hormonal responses. One group of recruits (exercised, n = 48) participated in moderate intermittent physical exercise, whereas a second group (non-exercised controls, n = 9) performed only light work in the barracks. Both groups participated in the same non-physical, classroom-type training and testing. Military training by the exercised group resulted in significant increases in CD4+ T-lymphocytes, renal cortisol excretion and the urinary noradrenaline/adrenaline ratio, together with reductions in neutrophils and the neutrophil/lymphocyte ratio. In the exercised group, the urinary noradrenaline/adrenaline ratio correlated positively with the training-induced changes in CD4+ T-lymphocytes and negatively with changes in the neutrophil/lymphocyte ratio. No significant relationship was found between training-induced increases in cortisol excretion and any of the peripheral blood cell alterations. Our results indicate that 4 weeks of military training consisting of intermittent moderate exercise resulted in a significant increase in CD4+ T-lymphocytes and reduction in neutrophils. These changes were probably driven by alterations in hormonal status, including the significant impact of sympathetic nervous system activation.  相似文献

To clarify the physical and mental fatigue caused by intense exercise and the relationship between the two types of fatigue, we examined changes in anthropometric and biochemical variables, neutrophil function, and the Profile of Mood States (POMS) questionnaire in 13 female university judoists attending a one-week training camp. Blood glucose, total cholesterol, haemoglobin, leukocyte count, IgG, and phagocytic activity all decreased after the training camp compared with baseline (P < or = 0.046). Aspartate aminotransferase, lactate dehydrogenase, creatine kinase, and neutrophil oxidative burst activity increased after the training camp (P < or = 0.007). Of the POMS scores, that for Fatigue increased after the training camp (P = 0.041) and that for Vigour decreased (P = 0.042). The changes in several POMS scores correlated with the changes in blood biochemical variables. In particular, the change in Total mood disturbance was negatively associated with changes in myogenic enzymes (P < or = 0.032). Our results suggest that intense exercise during training camps for female judoists leads to the appearance and accumulation of mental and physical fatigue, which are related to each other.  相似文献

Although epidemiological data indicate that athletes are at increased risk of upper respiratory tract infection during periods of heavy training and the 1 - 2 week period following endurance race events, there is very limited information on the responses to football training and match-play. For several hours after heavy exertion, components of both the innate (e.g. natural killer cell activity and neutrophil oxidative burst activity) and adaptive (e.g. T and B cell function) immune system exhibit suppressed function. Although such responses to football training and competition do not appear to be as pronounced, variations in immune cell numbers and function are reported in professional footballers over the course of a season. Attempts have been made through nutritional means (e.g. glutamine, vitamins C and E, and carbohydrate supplementation) to attenuate immune changes following intensive exercise and thus lower the risk of upper respiratory tract infection. Carbohydrate supplementation during heavy exercise has emerged as a partial countermeasure and attenuates increases in blood neutrophil counts, stress hormones, and inflammatory cytokines, but has little effect on decrements in salivary IgA output or natural killer cell function. Animal research indicates that other nutritional components such as beta-glucan, quercetin, and curcumin warrant human investigations to determine if they are effective countermeasures to exercise-induced immune dysfunction.  相似文献

Abstract

To clarify the physical and mental fatigue caused by intense exercise and the relationship between the two types of fatigue, we examined changes in anthropometric and biochemical variables, neutrophil function, and the Profile of Mood States (POMS) questionnaire in 13 female university judoists attending a one-week training camp. Blood glucose, total cholesterol, haemoglobin, leukocyte count, IgG, and phagocytic activity all decreased after the training camp compared with baseline (P ≤ 0.046). Aspartate aminotransferase, lactate dehydrogenase, creatine kinase, and neutrophil oxidative burst activity increased after the training camp (P ≤ 0.007). Of the POMS scores, that for Fatigue increased after the training camp (P = 0.041) and that for Vigour decreased (P = 0.042). The changes in several POMS scores correlated with the changes in blood biochemical variables. In particular, the change in Total mood disturbance was negatively associated with changes in myogenic enzymes (P ≤ 0.032). Our results suggest that intense exercise during training camps for female judoists leads to the appearance and accumulation of mental and physical fatigue, which are related to each other.  相似文献
