摘要:

文题释义:
高强度间歇训练(high intensity interval training,HIIT):是在短时间内进行全力、快速、爆发式锻炼的一种训练技术,其特点是:具有较大运动强度、短时间、多个运动训练模块且在间歇期间以较低强度运动或完全休息。通常会选取运动强度为85%-95%的最大摄氧量强度,小组性训练时间和其间的休息时间范围为若干秒至若干分钟。
鸢尾素(Irisin):是一种包含了112个氨基酸残基的多肽,运动过程中由肌肉分泌,直接作用于涉及能量代谢和体内平衡的白色脂肪细胞,诱导其转化为棕色脂肪细胞,被激活的棕色脂肪组织通过快速消耗葡萄糖和脂肪来发热从而预防或治疗人和啮齿类动物的许多代谢疾病。

背景:研究表明,高强度间歇训练较中等强度耐力训练更省时,且能有效降低内脏脂肪含量。
目的:拟通过对肥胖大鼠进行高强度间歇训练,观察训练后大鼠体脂的变化和比目鱼肌含Ⅲ型纤连蛋白域蛋白5(fibronectin type III domain containing protein 5,FNDC5)蛋白表达量以及血清鸢尾素水平。
方法:将80只5周龄健康雄性SD大鼠随机分为正常对照组(20只)和肥胖造模组(60只),并从造模成功的大鼠中随机挑选30只,随机分为肥胖安静对照组、肥胖运动对照组(中等强度运动组)和肥胖高强度间歇训练组(每组10只),饲养8周,记录大鼠体质量变化,末次安静或运动后12 h进行采样。测定大鼠体质量和体脂,免疫印迹法检测比目鱼肌FNDC5蛋白表达,并检测血清鸢尾素水平。实验方案经北京体育大学动物实验伦理委员会批准。
结果与结论:①较肥胖安静对照组,肥胖运动组大鼠体质量降低(P < 0.01),体脂成分下降(P < 0.05),FNDC5蛋白表达量增加(P < 0.01),血清中鸢尾素含量增高(P < 0.01);②高强度间歇训练组大鼠体质量明显低于中等强度运动组(P < 0.01),体脂成分低于中等强度运动组(P < 0.05),FNDC5蛋白表达量以及血清中鸢尾素含量明显高于中等强度运动组(P < 0.01);③结果说明,运动训练可通过增加血清中鸢尾素和FNDC5蛋白表达降低大鼠体脂;高强度间歇训练组大鼠较中等强度训练组体脂含量更低,血清中鸢尾素含量和比目鱼肌FNDC5蛋白表达量更高,即高强度间歇训练对肥胖大鼠减脂效果好。

Abstract: BACKGROUND: Studies have shown that high-intensity interval training is more time-saving than medium-intensity endurance training, which can effectively reduce visceral fat content.
OBJECTIVE: To observe the changes of body fat, fibronectin type III domain containing protein 5 (FNDC5) expression of the soleus muscle and serum irisin level after high-intensity interval training in obese rats. 
METHODS: Eighty healthy male Sprague-Dawley rats, 5 weeks old, were randomly divided into normal control group (n=20) and obesity group (n=60). The 30 rats were selected from the successful models and randomized into obesity quiet control group, moderate intensity exercise group and high-intensity intermittent training group (n=10 in each group), raising for 8 weeks. The change of the rat body mass was recorded, and samples were collected at quiet state after final exercise or at 12 hours after exercise. Body mass and body fat of the rats were measured, and the expression of FNDC5 in the soleus muscle was detected by immunoblotting, and the serum irisin level was determined. The experimental plan was approved by the Animal Experimental Ethics Committee of Beijing Sport University.
RESULTS AND CONCLUSION: Compared with the obesity quiet control group, the body mass of rats decreased (P < 0.01), body fat composition decreased (P < 0.05), FNDC5 protein expression increased (P < 0.01), and serum irisin level increased (P < 0.01) in the two obese exercise groups. Compared with the moderate-intensity exercise group, the body mass of rats was significantly lowered (P < 0.01), the body fat composition was decreased (P < 0.05), and the protein expression level of FNDC5 and the serum irisin levels were significantly increased in the high-intensity interval training group (P < 0.01). To conclude, exercise training can reduce body fat in rats by increasing the serum expression of irisin and FNDC5. The body fat content of rats in the high-intensity interval training group was lower than that in the moderate-intensity training group, and the serum irisin content and soles muscle FNDC5 protein expression were higher, indicating that the high-intensity interval training has a better effect on fat reduction in obese rats.
