有关运动与免疫的研究,大都集中在研究运动对普通人群和运动员上呼吸道感染的影响以及免疫机能的影响,这些研究的大部分案例都是针对年轻人和健康人群的。那么,运动免疫学领域还很大,尤其是对那些疾病、亚健康和特殊年龄段的人群的研究仍是相对薄弱的地方。对特殊人群(HIV感染人群、老年人、儿童、肥胖和糖尿病)的运动、感染风险和免疫机能进行综述。  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

由于新型冠状病毒(2019-nCoV)感染的肺炎疫情暴发,人们将居家运动作为提高免疫力与保持健康的重要手段,运动与免疫的关系再度受到关注。一般认为,在充分恢复的前提下进行规律的中高强度运动可提高免疫功能,而急性运动(acute exercise)可能抑制免疫功能并增加感染风险。急性运动后外周血淋巴细胞计数及功能降低、免疫球蛋白A水平分泌减少被认为是运动抑制免疫的理论基础。但目前这种独立于非运动因素影响免疫功能增加感染风险的认识受到了现有研究的挑战。急性运动可通过应激反应将淋巴细胞亚群迅速动员至循环中,运动结束后,淋巴细胞亚群又会迅速迁移至外周组织。淋巴细胞的重新分布(lymphocyte redeployment)可能是一种进化保守的免疫机制,这一过程强化了外周组织的免疫监视与调节功能,有助于提升机体抵抗感染能力。因此,从这一视角就急性运动对机会性感染风险及免疫功能影响的现状进行综述。  相似文献

支链氨基酸(BCAAs)是蛋白类运动营养补剂中相当重要的营养素,不同项目的运动员由于膳食不能满足大强度运动训练的营养需求,经常需要额外补充含BCAAs的蛋白类营养补剂。但长期过量地补充可能对机体的免疫力、肾脏功能、消化系统等产生不良影响。采用文献综述法,对补充支链氨基酸对抗阻运动和耐力运动的作用机制进行了总结,并分析其对机体免疫力的影响和过量补充的负面影响机制,探讨运动员如何合理补充支链氨基酸,避免对身体造成损害。  相似文献

运动过程中骨骼肌产生的高水平反应物会导致肌肉损伤和肌肉功能受损,一般认为补充抗氧化剂可以保护肌肉不受损伤。无论对于运动爱好者还是专业运动员,抗氧化剂都是最常用的运动补剂之一。目前备受关注的是用额外口服抗氧化剂的方法来支持内源性防御系统,从而实现预防或减轻氧化应激、减少肌肉损伤并改善运动表现。目前有大量已发表的研究对该主题进行了讨论,大多数研究表明,抗氧化剂可以减轻运动引起的氧化应激,但大多数研究都未发现其对肌肉损伤和肌肉功能有任何影响。此外,越来越多的证据表明,抗氧化剂对健康和训练适应有消极作用。本文深入分析总结了关于活性物质(Reactive Species)在体内的作用以及服用抗氧化剂对维持健康和提高身体性能的功效的文献。  相似文献

Recommendations to maintain immune health in athletes   总被引:1,自引:0,他引:1  
Numerous studies over the last 35 years report an increase in upper respiratory infection (URI) symptoms in athletes during periods of heavy training and competition. Challenges athletes face such as heavy exercise and life stress influence immune function via activation of the hypothalamic–pituitary–adrenal axis and the sympathetic nervous system and the resulting immunoregulatory hormones. Both innate and acquired immunity are often reported to decrease transiently in the hours after heavy exertion, typically 15–70%: prolonged heavy training sessions in particular have been shown to decrease immune function; potentially providing an ‘open window’ for opportunistic infections. Whether the observed changes in immunity with acute strenuous exercise or periods of heavy training account for the increased susceptibility to URI symptoms remains contentious. Nevertheless, there is little doubt that URI symptoms hinder athletic training and competition; underpinning the need to identify the prominent risk factors and appropriate countermeasures. Recent studies have identified prominent risk factors, including: intensified training in the winter; long-haul travel; low energy availability; high levels of psychological stress and anxiety; and depression. Given the shared pathways and effector limbs for the body’s response to physical and psychological challenges, it is logical that psychological strain influences immunity and illness incidence in athletes under heavy training; indeed, stress and anxiety have recently been shown to modify the immune response to exercise. This mini-review provides new insights and evidence-based recommendations for coping with the various challenges that athletes encounter on immune health, including: heavy exercise; life stress; sleep disruption; environmental extremes and nutritional deficits.  相似文献

BackgroundIn recent years, much evidence has emerged to indicate that exercise can benefit people when performed properly. This review summarizes the exercise interventions used in studies involving mice as they are related to special diseases or physiological status. To further understand the effects of exercise interventions in treating or preventing diseases, it is important to establish a template for exercise interventions that can be used in future exercise-related studies.MethodsPubMed was used as the data resource for articles. To identify studies related to the effectiveness of exercise interventions for treating various diseases and organ functions in mice, we used the following search language: (exercise [Title] OR training [Title] OR physical activity [Title]) AND (mice [title/abstract] OR mouse [title/abstract] OR mus [title/abstract]). To limit the range of search results, we included 2 filters: one that limited publication dates to “in 10 years” and one that sorted the results as “best match”. Then we grouped the commonly used exercise methods according to their similarities and differences. We then evaluated the effectiveness of the exercise interventions for their impact on diseases and organ functions in 8 different systems.ResultsA total of 331 articles were included in the analysis procedure. The articles were then segmented into 8 systems for which the exercise interventions were used in targeting and treating disorders: motor system (60 studies), metabolic system (45 studies), cardio-cerebral vascular system (58 studies), nervous system (74 studies), immune system (32 studies), respiratory system (7 studies), digestive system (1 study), and the system related to the development of cancer (54 studies). The methods of exercise interventions mainly involved the use of treadmills, voluntary wheel-running, forced wheel-running, swimming, and resistance training. It was found that regardless of the specific exercise method used, most of them demonstrated positive effects on various systemic diseases and organ functions. Most diseases were remitted with exercise regardless of the exercise method used, although some diseases showed the best remission effects when a specific method was used.ConclusionOur review strongly suggests that exercise intervention is a cornerstone in disease prevention and treatment in mice. Because exercise interventions in humans typically focus on chronic diseases, national fitness, and body weight loss, and typically have low intervention compliance rates, it is important to use mice models to investigate the molecular mechanisms underlying the health benefits from exercise interventions in humans.  相似文献

Exercise, nutrition and immune function   总被引:12,自引:0,他引:12  
Strenuous bouts of prolonged exercise and heavy training are associated with depressed immune cell function. Furthermore, inadequate or inappropriate nutrition can compound the negative influence of heavy exertion on immunocompetence. Dietary deficiencies of protein and specific micronutrients have long been associated with immune dysfunction. An adequate intake of iron, zinc and vitamins A, E, B6 and B12 is particularly important for the maintenance of immune function, but excess intakes of some micronutrients can also impair immune function and have other adverse effects on health. Immune system depression has also been associated with an excess intake of fat. To maintain immune function, athletes should eat a well-balanced diet sufficient to meet their energy requirements. An athlete exercising in a carbohydrate-depleted state experiences larger increases in circulating stress hormones and a greater perturbation of several immune function indices. Conversely, consuming 30-60 g carbohydrate x h(-1) during sustained intensive exercise attenuates rises in stress hormones such as cortisol and appears to limit the degree of exercise-induced immune depression. Convincing evidence that so-called 'immune-boosting' supplements, including high doses of antioxidant vitamins, glutamine, zinc, probiotics and Echinacea, prevent exercise-induced immune impairment is currently lacking.  相似文献
