摘要
目的对比观察高强度间歇运动(HIIT)与中等强度持续运动(MICT)对肥胖患者腹部内脏脂肪的影响。方法采用随机数字表法将68例肥胖女性大学生分为HIIT组(23例)、MICT组(22例)及对照组(23例)。所有受试者均保持日常生活习惯不变,实验期间MICT组辅以MICT干预[运动强度为60%最大摄氧量(VO2max)水平],HIIT组则辅以HIIT干预[运动强度为90%VO2max水平,每运动4 min则间歇3 min],2组受试者每次做功量均为300 kJ,对照组不给予任何附加运动,干预时间为12周。于实验前、实验结束后48 h采用计算机断层扫描(CT)测量各组受试者腹部内脏脂肪面积(AVFA)及腹部皮下脂肪面积(ASFA);采用双能X线骨密度仪测量各组受试者体脂百分比(FM%)、全身FM以及腹部区域、臀部区域和躯干FM含量。结果实验后发现HIIT组及MICT组AVFA[分别为(60.1±7.5)cm^(2)和(60.9±9.6)cm^(2)]、ASFA[分别为(215.0±41.7)cm^(2)和(216.5±34.1)cm^(2)]、FM%[分别为(29.8±3.8)%和(31.2±4.1)%]、全身FM[分别为(19.9±2.5)kg和(20.4±2.2)kg]、腹部区FM[分别为(1.75±0.26)kg和(1.71±0.23)kg]、臀部区FM[分别为(4.01±0.49)kg和(4.23±0.47)kg]及躯干FM[分别为(10.0±1.7)kg和(10.4±1.9)kg]均较实验前明显降低(P<0.05),且上述指标HIIT组与MICT组差异均无统计学意义(P>0.05);实验后对照组上述各项指标均无明显变化(P>0.05)。结论HIIT及MICT干预均可降低肥胖女性大学生腹部内脏脂肪含量,且两种运动方式作用效果类似。
Objective To compare the effect of high-intensity interval training(HIIT)and moderate-intensity continuous training(MICT)on the abdominal visceral fat of obese women.Methods Sixty-eight obese female college students were randomly divided into an HIIT group(n=23),an MICT group(n=22)and a control group(n=23).The control group was not given any training intervention.The MICT group performed continuous exercise at an intensity of 60%of each person′s maximum oxygen uptake(VO2max)until 300kJ of work had been performed.Those in the HIIT group performed repeated 4-minute bouts of cycling at 90%of their VO2max with 3-minute intervals until 300kJ of work had been performed.The interventions lasted 12 weeks.The subjects′visceral fat(AVFA)and abdominal subcutaneous fat(ASFA)were measured using computed tomography.Whole-body fat mass(FM)and FM in the android,gynoid and trunk regions were detected using dual energy X-ray absorptiometry before and 48 hours after the final session.Results After the intervention,the average AVFA,ASFA,percentage of fat mass(FM%),whole-body FM,and FM in the abdominal,gluteo-femoral and trunk regions of the HIIT group and MICT group were significantly lower than before the intervention,but there was no significant difference between them.No significant differences were observed in any of the control group′s indexes.Conclusions Both HIIT and MICT can reduce the abdominal visceral fat of obese female college students,and the effects of the two exercise modes are equivalent.
