客观的。评估热量限制诱导的减肥（有或没有有氧运动）对肝脏脂肪的影响。方法。 33 名患有内脏肥胖的成年人被分为热量限制组（CR；n = 18）或 CR 和有氧运动组（CR + Ex；n = 15）。目标能量摄入量为25kcal/kg理想体重。 CR + Ex 组的目标运动时间为每周 300 分钟或以上，乳酸阈值强度持续 12 周。结果。体重（CR，-5.3±0.8 kg；CR+Ex，-5.1±0.7 kg）、脂肪量（CR，-4.9±0.9kg；CR+Ex，-4.4±0.6 kg）和内脏脂肪（CR，-24±5 cm2；CR+Ex，-37±5 cm2）的减少没有统计学意义组间不同。两组的肝脏脂肪均显着下降，但组间无差异。 CR+Ex组的最大摄氧量变化显着大于CR组（CR，-0.7±0.7mL/kg/min；CR+Ex，2.9±1.0mL/kg/min）。结论。 CR 和 CR + Ex 均能改善肝脏脂肪的减少；然而，运动训练并没有产生累加效应。
Objective. To evaluate the effect of calorie restriction-induced weight loss with or without aerobic exercise on liver fat. Methods. Thirty-three adults with visceral adiposity were divided into calorie restriction (CR; n = 18) or CR and aerobic exercise (CR + Ex; n = 15) groups. Target energy intake was 25 kcal/kg of ideal body weight. The CR + Ex group had a targeted exercise time of 300 min/wk or more at lactate threshold intensity for 12 weeks. Results. Reductions in body weight (CR, −5.3 ± 0.8 kg; CR + Ex, −5.1 ± 0.7 kg), fat mass (CR, −4.9 ± 0.9 kg; CR + Ex, −4.4 ± 0.6 kg), and visceral fat (CR, −24 ± 5 cm2; CR + Ex, −37 ± 5 cm2) were not statistically different between groups. Liver fat decreased significantly in both groups, with no difference between groups. Change in maximal oxygen uptake was significantly greater in the CR + Ex group than in the CR group (CR, −0.7 ± 0.7 mL/kg/min; CR + Ex, 2.9 ± 1.0 mL/kg/min). Conclusion. Both CR and CR + Ex resulted in an improved reduction in liver fat; however, there was no additive effect of exercise training.
