肥胖者有氧运动抗炎效应的实验研究   总被引：1，自引：0，他引：1  
目的:基于"肥胖炎症反应"(inflammtion effect in obese)理论,通过对运动干预前、后肥胖者血清标志性炎症因子TVF-α、IL-6以及促炎因子NF-κB、SOCS-3等水平变化的分析,就运动抗炎效应做一探索性研究.方法:将苏州市某街道若干社区55～60岁肥胖女性居民共41名随机分为2组,以运动处方进行16周的有氧运动干预;干预前、后分别检测肥胖相关形态指标及炎症相关血液生化指标(TNF-α、IL-6和NF-κB、SOCS-3等).结果:有氧运动干预后,肥胖者体重减轻、BMI和WHR减小的同时,其血清TNF-a、IL-6水平随之降低,有效改善了肥胖及其炎症状态;血清NF-κB、SOCS-3表达随之下调,HOMA-IR减小,有效缓解了胰岛素抵抗状态.结论:有氧运动干预对肥胖炎症状态具有良好的抗炎效应.  相似文献

不同运动方式对绝经后女性IL-6、TNF-α和hs-CRP的影响   总被引：2，自引：0，他引：2  
目的比较12周有氧运动或抗阻训练对绝经后女性白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)和高敏C-反应蛋白(hs-CRP)影响的差异,为制定特异性的运动处方提供依据。方法将符合标准的受试者随机分为有氧运动组(18人),抗阻训练组(17人)和对照组(20人)。有氧运动组和抗阻训练组进行每周3次、共12周的运动干预,对照组保持日常生活习惯不变。实验前后分别测定血清IL-6、TNF-α、hs-CRP等指标。结果 12周运动干预后,有氧运动组血清IL-6较运动前下降了13%(P<0.01),血清TNF-α(P>0.05)和hs-CRP(P>0.05)无显著性变化;抗阻训练组血清IL-6较运动前无显著性变化(P>0.05),但血清TNF-α和hs-CRP分别下降了11%(P<0.05)和26%(P<0.05)。对照组所有指标的变化不明显。相关分析显示,实验前hs-CRP基础值与BMI(r=0.36,P<0.01)、空腹血糖(r=0.23,P<0.05)和IL-6(r=0.22,P<0.01)正相关,与VO2max(r=-0.29,P<0.05)负相关;实验后hs-CRP的变化值与BMI的变化值(r=0.21,P<0.05)正相关。结论 绝经妇女慢性全身性炎症状态与其BMI、血糖水平和体内炎症因子的水平有关;12周有氧运动或抗阻训练均能有效改善绝经后女性慢性全身性炎症状态,但抗阻训练的效果优于有氧运动,其原因与BMI的改善有关。  相似文献

为了解不同负荷游泳运动对高脂血症大鼠血清CRP、IL-6以及TNF-α的影响,将雄性Wistar大鼠50只,随机抽取10只作为正常对照组(NC),其余为高脂组.高脂血症模型建立成功后再将高脂组大鼠随机分成高脂血症安静对照组(HC)、高脂血症1 h有氧运动组(HE1)、高脂血症2 h有氧运动组(HE2)和高脂血症一次力竭运动组(HE3).然后各组动物酶免法测定血清CRP,放免法测定血清IL-6、TNF-α.结果:(1)HC组大鼠血清CRP非常显著高于NC组(P<0.01).HE1组显著低于HC组(P<0.05),但仍明显高于NC组(P<0.05).(2)HC组大鼠血清IL-6显著高于NC组(P<0.05),HE3组非常显著高于HC组(P<0.01).(3)HC组大鼠血清TNF-α显著高于NC组(P<0.05),HE2组大鼠非常明显高于HC组(P<0.01).(4)CRP与TNF-α之间呈显著的低度负相关(r=-0.460,P=0.008).结果表明,就循环CRP、IL-6、TNF-α水平而言,并非运动时间越长,对高脂血症越有好处,因此,不提倡一次长时间有氧运动,更不提倡达到疲劳状态;运动引起高脂血症大鼠血清CRP的变化可能与IL-6无关.  相似文献

Abstract

The aim of this study was to determine whether endurance training in athletes induces airway inflammation and pulmonary function disorders. Respiratory pattern and function were analysed in ten healthy endurance runners at rest, during sub-maximal exercise, and during the recovery. Inflammatory cells and metabolites (histamine, interleukin-8, and leukotriene E4) were measured in sputum at rest and after exercise. The experiments were conducted on three different occasions (basic endurance training, pre-competitive and competitive periods). In spite of the absence of post-exercise spirometric changes and respiratory symptoms, airway cells counts and inflammatory markers changed significantly. At the beginning of the experiment, athletes' induced sputum showed an abundance of macrophages compared with neutrophils. We found a high percentage of neutrophils during the pre-competitive and competitive periods of the sport season (41% and 37%), a significant increase in macrophage counts during the pre-competitive period (51%), and a significant rise in total cells, interleukin-8, leukotriene E4, and histamine during the competitive period. In conclusion, one year's training increased markers of inflammation in the airways of endurance runners without symptoms or changes in pulmonary function, suggesting that airway inflammation is of insufficient magnitude to markedly impact lung function in healthy athletes.  相似文献

目的探讨运动训练后进行冷水浸泡在促进机体恢复过程中是否会对机体炎症反应产生影响。方法 72只8周龄SD大鼠,对照组C组(n=24)、运动组E组(n=24)、运动冷水浸泡组CWI组(n=24),每组根据取材时间分为0h、24h、72h等小时组,运动组、运动冷水浸泡组的大鼠进行跑台离心运动,之后运动冷水浸泡组进行10℃冷水浸泡10min;Western Blot测腓肠肌TNF-α蛋白含量,ELISA测血浆中TNF-α含量。结果腓肠肌中TNF-α蛋白在C和E组之间均有显著性差异(p<0.01),在C和CWI组之间的0h、24h均有显著性差异(p<0.01),E和CWI组之间在0h未有差异(p>0.05);血浆中TNF-α在C和E、CWI组之间均有显著性差异(p<0.05或p<0.01),但E、CWI组之间仅在72h显著性差异(p<0.05)。结论运动后大鼠骨骼肌和血浆中TNF-α表达上调,运动后进行冷水浸泡在前期能够加强炎症反应,后期促使机体更快的恢复到正常水平,这可能是冷水浸泡促进机能恢复的部分原因。  相似文献

Prospective application of serum cytokines, lipopolysaccharide (LPS), and heat shock proteins (eHSPs) requires reliable measurement of these biomarkers that can signify exercise-induced heat stress in hot conditions. To accomplish this, both short-term (7 day) reliability (at rest, n = 12) and the acute responsiveness of each biomarker to exercise in the heat (pre and post 60-min cycling, 34.5°C and 70% RH, n = 20) were evaluated. Serum was analysed for the concentration of C-reactive protein (CRP), interleukin-6 (IL-6), heat shock protein 72 (eHSP72), immunoglobulin M (IgM) and LPS. Test–retest reliability was determined as the coefficient of variation (CV). Biomarkers with the least short-term within-participant variation were IL-6 (19%, ±20%; CV, ±95% confidence limits (CL)) and LPS (23%, ±13%). Greater variability was observed for IgM, eHSP72 and CRP (CV range 28–38%). IL-6 exhibited the largest increase in response to acute exercise (95%, ±11%, P = < 0.001) and although CRP had a modest CV (12%, ±7%), it increased substantially post-exercise (P = 0.02, ES; 0.78). In contrast, eHSP72 and LPS exhibited trivial changes post-exercise. It appears variation of common inflammatory markers after exercise in the heat is not always discernible from short-term (weekly) variation.  相似文献

Various inflammation parameters are increased with childhood obesity, but few comparable data are found in lean growing athletes. This study aims to characterize differences in 12 simultaneously measured inflammatory parameters between pubertal rhythmic gymnasts (RG) and untrained controls (UC), and to examine the relationship between body composition and inflammatory markers. Sixty 10–12-year-old girls were divided into RG (n?=?30) and UC (n?=?30). Fat mass (FM) and fat free mass (FFM) were measured by dual-energy X-ray absorptiometry. Leptin and 12 inflammatory parameters (interleukin [IL]-2, IL-4, IL-6, IL-8, IL-10, vascular endothelial growth factor, interferon-gamma [IFN-γ], tumor necrosis factor-alpha, IL-1α, IL-1β, monocyte chemotactic protein-1 and epidermal growth factor) were measured from fasting blood samples. No differences were seen in 12 inflammatory markers between studied groups. As expected, leptin (RG: 2.4?±?1.1; UC: 7.6?±?4.2?ng?ml?1) and FM (RG: 7.3?±?2.3; UC: 11.8?±?5.1?kg) were lower (p?<?.05) in RG compared to UC. In the whole group of lean pubertal girls, 69.0% of the variability in body FM was determined by leptin, and 11.2% of the variability in body FFM was explained by IFN-γ. In conclusion, measured 12 inflammatory biomarkers were not different between RG and UC, despite lower leptin and FM in RG. In lean pubertal girls, IFN-γ was independently associated with FFM, and leptin with FM.  相似文献

Purpose: This study examined postexercise inflammatory and leukocyte responses in smokers and nonsmokers, as well as the effects of cigarette smoking on the acute postexercise inflammatory and leukocyte response in habitual smokers. Method: Eleven recreationally active male smokers and 11 nonsmokers matched for age and aerobic fitness were familiarized and underwent baseline fitness testing. Participants then completed 40 min of cycling at 50% peak aerobic workload. Smokers performed 2 randomized exercise sessions, including an acute postexercise smoking condition (2 cigarettes in 15 min of 12 mg tar and 1 mg nicotine) and a no-smoking condition, while nonsmokers performed 1 exercise session without smoking. Venous blood was obtained preexercise and postexercise for analysis of interleukin (IL)-6, IL-1 receptor antagonist (ra), tumor necrosis factor-alpha (TNF-α), and c-reactive protein (CRP). Results: No differences existed between groups for resting CRP (d = 0.25–0.46; p = .374–.617). Despite no baseline difference (d = 0.03–0.07; p = .141–.70), exercise-induced increases were observed for IL-1 ra in smokers (d = 0.50; p = .024–.033), which was not observed in the never-smoker group. No between-group difference was observed for IL-6 across all points (d = 0.09–0.5; p = .102–.728); however, all groups observed significant within-group change (d = 0.27–1.09; p = .001–.042). Further, TNF-α for smokers smoking was elevated above both smokers not smoking and nonsmokers at baseline and across the protocol (d = 1.20–1.80; d = 0.20–1.0; p = .001–.035). Additionally, a marked postexercise increase in leukocyte and neutrophil concentrations was evident in smokers smoking compared with nonsmokers and smokers not smoking as indicated by a moderate-to-large effect size (d = 0.72; d = 0.78). Conclusion: Consequently, male smokers exhibit an altered postexercise proinflammatory profile compared with age- and fitness-matched nonsmokers.  相似文献

The objective was to investigate the relationship between IL-1B rs16944, IL-6 rs1800795, and CASP8 rs3834129 genetic polymorphisms and concussion severity. Rugby players from high school, senior amateur, and professional teams completed a concussion severity questionnaire and donated a DNA sample. Participants (n = 163) were split into symptom severity groups around the median number and duration of symptoms. The frequency of participants with high symptom counts (more than five symptoms) increased across the IL-1B (C/C: 35%; C/T: 51%; T/T: 56%; P = 0.047) and the IL-6 (C/C: 31%; C/G: 44%; G/G: 58%; P = 0.027) genotypes. The C–C inferred interleukin allele construct frequency, created from combining the IL-1B and IL-6 genotype data, was lower in participants reporting a high symptom count (18%), compared to those with a low symptom count (fewer than six symptoms, 36%, P = 0.002). Similarly, the C–C inferred interleukin allele construct frequency was lower in those reporting prolonged symptom duration (more than one week, 16%), as opposed to short symptom duration (less than one week, 34%, P = 0.015). This study provides evidence of novel inflammatory pathway genetic associations with concussion severity, which supports the hypothesis implicating neuroinflammation in the development of concussion symptoms.  相似文献
