摘要 背景:最大摄氧量(VO2max)是评定心肺耐力及运动能力最直接有效的客观指标,但目前研究中反映大鼠较长时间最大摄氧量变化数据的文章较少,尚未见有关高强度间歇训练对大鼠增龄过程中心肺耐力持续变化影响的相关报道。目的:探讨16周高强度间歇训练对大鼠心肺耐力的改善作用,并通过对29周龄大鼠最大摄氧量持续16周测定,为实验动物训练强度的量化提供数据参考。方法:将28只29周龄雄性Wistar大鼠分为2组:安静对照组大鼠正常饮食生活,无训练;高强度间歇训练组大鼠进行高强度(90%最大摄氧量)、低强度(50%最大摄氧量)的间歇运动,为期16周,每周5次,平均每2周测定最大摄氧量、完成最大摄氧量测试对应的最大跑速变化,并针对2组大鼠最大摄氧量和最大跑速值进行对比及相关分析。实验经北京体育大学运动科学实验伦理委员会批准(2015025)。结果与结论:①29-45周龄增龄过程中最大摄氧量出现下降-上升-下降波动,16周后,高强度间歇训练组大鼠最大摄氧量下降了31.6%,安静对照组大鼠最大摄氧量下降了47.9%,高强度间歇训练组大鼠最大摄氧量显著高于安静对照组(P<0.01);②干预6,8,16周时高强度间歇训练组最大摄氧量下降幅度显著低于安静对照组(P<0.05或P<0.01);③干预4,8周时高强度间歇训练组最大跑速值显著高于安静对照组(P<0.05或P<0.01);④最大摄氧量与最大跑速的相对值呈正相关;⑤结果说明,年龄的增加是大鼠心肺耐力下降的不可逆因素,但高强度间歇训练可延缓心肺耐力下降趋势;高强度间歇训练干预6周后可明显降低大鼠因增龄导致的心肺耐力下降幅度,8周后可有效延缓大鼠因增龄导致的心肺耐力下降;高强度间歇训练干预4周后大鼠最大跑速提高,运动能力增强。 BACKGROUND:Maximal oxygen uptake(VO2 max)is the most direct,effective and objective index for determining cardiorespiratory endurance and exercise capacity,but there are few studies on the varying data of VO2 max in rats for a long time.In addition,the effect of high-intensity interval training on the cardiorespiratory endurance in rats during age increasing has not yet been reported.OBJECTIVE:To investigate the improvement of 16-week high-intensity interval training on the cardiorespiratory endurance in rats,and to continuously measure the VO2max for 16 weeks in 29-week-old rats,so as to provide data reference for the precise control of training intensity.METHODS:Twenty-eight male Wistar rats aged 29 weeks old were randomly assigned into a quiet control group(normal feeding,no training)and a high-intensity interval training group.The latter group underwent the interval exercise of high-intensity(90%VO2 max)and low-intensity(50%VO2 max),5 times per week,for 16 weeks.The VO2 max and corresponding maximal running velocity were tested and compared every 2 weeks.The study was approved by the Ethics Committee of Sports Science and Physical Health Education Department,Beijing Sport University,with the approval No.2015025.RESULTS AND CONCLUSION:(1)With the increasing age from 29 to 45 weeks,the VO2max fluctuated down-up-down.After 16 weeks of exercise,the VO2max was decreased by 31.6%in the high-intensity interval training group and 47.9%in the quiet control group.The VO2max in the high-intensity interval training group was significantly higher than that in the quiet control group(P<0.01).(2)The decrease of VO2max in the high-intensity interval training group was significantly lower than that in the quiet control group at 6,8,and 16 weeks(P<0.05 or P<0.01).(3)The increase of maximal running velocity in the high-intensity interval training group was significantly higher than that in the quiet control group at 4 and 8 weeks(P<0.05 or P<0.01).(4)The maximal running velocity was positively correlated with VO2max in rats.(5)
