目的:通过多级负荷力竭跑台运动的预实验建立运动性贫血的模型。方法:用sysmexF-820血细胞分析仪对所有实验大鼠进行断尾取血一次测定血红蛋白(Hb)、红细胞数目(RBC)和红细胞比积(Hot)。结果:10周多级负荷力竭跑台运动后,运动组的Hb较对照组降低12.4%,有高度显著性差异(P〈0.01);运动组RBC和Hot均分别低于对照组2.7%和2.9%,无统计学意义。结论:10周多级负荷力竭跑台运动可导致运动组大鼠Hb较对照组高度显著性下降(P〈0.01),说明此运动性贫血模型是成功的,但耗时太长,跑台的利用率很不经济。  相似文献

力竭运动及慢性心理应激对血尿素氮和皮质醇的影响   总被引:1,自引:0,他引:1  
通过建立心理应激和力竭运动动物模型,测定慢性心理应激和力竭运动后大鼠血清中血尿素氮的含量及皮质醇的含量,揭示运动及心理应激对免疫功能的影响。结论:力竭运动使血尿素氮升高,该实验运动模型的建立比较合理。慢性情绪应激基础上的力竭运动会引起皮质醇含量的显著升高,其可能的机理是情绪应激加上力竭运动,比单一的应激引起机体的应激状态更为明显。  相似文献

Growing evidence has demonstrated exercise as an effective way to promote cardiovascular health and protect against cardiovascular diseases However, the underlying mechanisms of the beneficial effects of exercise have yet to be elucidated. Animal exercise studies are widely used to investigate the key mechanisms of exercise-induced cardiovascular protection. However, standardized procedures and well-established evaluation indicators for animal exercise models are needed to guide researchers in carrying out effective, high-quality animal studies using exercise to prevent and treat cardiovascular diseases. In our review, we present the commonly used animal exercise models in cardiovascular research and propose a set of standard procedures for exercise training, emphasizing the appropriate measurements and analysis in these chronic exercise models. We also provide recommendations for optimal design of animal exercise studies in cardiovascular research, including the choice of exercise models, control of exercise protocols, exercise at different stages of disease, and other considerations, such as age, sex, and genetic background. We hope that this position paper will promote basic research on exercise-induced cardiovascular protection and pave the way for successful translation of exercise studies from bench to bedside in the prevention and treatment of cardiovascular diseases.  相似文献

The ability to examine within-person change is essential to test process-based theories in sport and exercise psychology. Longitudinal data, whether experimental or observational, are prerequisites to be able to examine change processes, but most longitudinal studies in sport and exercise psychology focus solely on between-person/group differences, not on within-person change. In this review, we (1) provide researchers in the sport and exercise psychology field with a framework for longitudinal research that focuses on within-person change; (2) provide an overview of how researchers in sport and exercise psychology currently analyse longitudinal data, which showed that most longitudinal studies focus on between-person/group differences; and (3) provide examples of statistical models for analysing longitudinal data that correspond to the framework for longitudinal research. In the examples, we focus on latent variable modelling, such as latent growth-curve modelling and latent change-score modelling, which capture within-person change. We argue that there is a need for stronger emphasis on the match among theory of change, temporal design, and statistical models when designing longitudinal studies in sport and exercise psychology.  相似文献

Growing literature has demonstrated that exercise may be an effective prevention and treatment option for drug addiction. In the past few years, many studies have suggested that there were sex differences in all phases of drug addiction. However, very limited research has investigated sex differences in the effectiveness of exercise intervention in drug addiction and rehabilitation. In this mini review, we summarize the effect of sex on the results of using exercise to prevent and treat drug addiction. The studies we consider span various animal models and use multiple types of exercise to examine the effectiveness of exercise on the neurobiological mechanism of exercise rehabilitation. We believe that exercise as an adjuvant intervention strategy can be applied better in drug addiction prevention and recovery.  相似文献

Abstract

The problem under investigation in this study was to determine if differing programs of prepuberty exercise had any effect upon the emotionality of male albino rats at puberty. The subjects were 48 male albino rats of the Sprague-Dawley strain who were subjected to a 35-day training program under conditions of sedentary existence, voluntary exercise, or forced exercise. At the end of the experimental period the animals were tested in an open field marked into 49 consecutively numbered 7 1/2-in. squares.

Emotionality in the open field was determined by two methods: (a) the total number of squares traversed by an animal in 5 min., and (b) the total number of squares traversed by an animal toward the center of the field. The relationship between exploratory behavior and emotionality is considered to be an inverse one, that is, the more exploratory the behavior, the less emotionality the animal exhibits.

The results indicated that the animals which had been subjected to the forced exercise regimen traversed significantly more squares under both testing conditions and therefore evidenced more exploratory behavior and therefore less emotionality than the animals in the voluntary exercise and sedentary groups. There were no significant differences on either measure of exploratory behavior between the voluntary exercise and sedentary groups.  相似文献

模拟高原训练是能够避免高原训练弊端,最大程度激发机体生理潜能,提高运动员竞技水平的有效方法。本研究尝试从设计交替训练的海拔高度着手,通过应用人工低压氧舱模拟高原训练方法,建立固定海拔2500m、4000m以及2500m~4000m交替低氧训练的动物模型,通过应用生理和生化方法对大鼠心肌相关指标进行检测及研究分析,探讨不同海拔及交替海拔训练条件下大鼠心肌抗氧化能力、有氧代谢能力等的变化,从而为运动员高——高交替训练提供参考。实验以雄性Wister大鼠为实验对象,以递增负荷跑台训练方式建立动物训练模型。将筛选后的大鼠随机分为:常氧运动组、2500m低氧运动组、4000m低氧运动组、交替低氧运动组,每组8只。第1周到第4周各组分别以不同的跑台训练模型进行训练,下高原后第5天以25m/min的速度跑至力竭。全部断头处死后,取心肌组织,分别测试各组大鼠心肌中SOD、MDA、SDH、LDH、Ca^2+-ATP酶活性的变化。实验结果表明:经过4周不同海拔低氧递增负荷跑台训练及下高原后4天的训练,交替低氧运动组大鼠心肌各指标,如SOD、SDH、Ca^2+-ATP酶活性均高于其他各组,MDA低于其他各组,LDH活性组间无显著性变化。说明交替低氧训练既可以维持较高海拔的低氧刺激,又可以减少过高海拔造成的损伤,有利于机体恢复。  相似文献

运动训练对高脂膳食大鼠主动脉M_2受体的影响   总被引:4,自引:0,他引:4  
目的 探讨运动训练对高脂膳食大鼠主动脉M2受体表征的影响.方法 通过建立动物模型,采用跑台训练方式,运用免疫组织化学方法,研究大鼠主动脉M2受体的分布以及运动训练对高脂膳食大鼠主动脉M2受体表达的影响.结果 与安静对照组比较,有氧运动组和高脂膳食加有氧运动组主动脉M2受体表达的平均光密度值(MOD)显著增加;大强度运动组和高脂膳食组均减少,但高脂膳食组差异较显著.结论 大鼠主动脉上有M2受体分布;大强度运动可使高脂膳食大鼠主动脉M2受体的表达减少,但高脂膳食对其影响较为显著;有氧运动显著增加正常大鼠和高脂膳食大鼠主动脉M2受体的表达.因此认为,有氧运动可通过迷走神经有效预防和改善动脉粥样硬化(AS)的发生和发展.  相似文献
