在 33 名肥胖男性中评估了仅饮食 (DO) 和饮食结合有氧 (DA) 或抗阻 (DR) 运动对皮下脂肪组织 (SAT)、内脏脂肪组织 (VAT)、瘦肉组织 (LT) 和骨骼肌 (SM) 组织的影响（DO，n = II；DA，n = II；DR，n = 11）。所有组织均使用全身多层磁共振成像（MRT）模型进行测量。在每组中，观察到体重、SAT 和 VAT 显着降低（P < 0.05）。体重（约 10%）、SAT（约 25%）和 VAT 体积（约 35%）的减少在各组之间没有差异（P > 0.05）。对于所有治疗，VAT 的相对降低幅度均大于 SAT (P < 0.05)。仅对于 DA 和 DR 组，腹部 SAT 的降低（大约 27%）比臀股区域观察到的降低（大约 20%）更大（P < 0.95）。相反，无论治疗如何，整个腹部 VAT 的减少都是均匀的 (P > 0.05)。单独 DO 组上半身和下半身区域的 MRI-LT 和 MRI-SM 均下降（P < 0.05）。 DA 组的 O-2 吸收峰值（升）显着改善（接近 14%），DR 组的肌肉力量也显着改善（接近 20%）（P < 0.01）。这些发现表明，与臀股区域相比，DA 和 DR 可以更好地保存 MRI-SM、从腹部区域动员 SAT，并且与肥胖男性的 DO 相比，功能能力得到改善。
The effects of diet only (DO) and diet combined with either aerobic (DA) or resistance (DR) exercise on subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), lean tissue (LT), and skeletal muscle (SM) tissue were evaluated in 33 obese men (DO, n = II; DA, n = II; DR, n = 11). All tissues were measured by using a whole body multislice magnetic resonance imaging (MRT) model. Within each group, significant reductions were observed for body weight, SAT, and VAT (P < 0.05). The reductions in body weight (similar to 10%) and SAT (similar to 25%) and VAT volume (similar to 35%) were not different between groups (P > 0.05). For all treatments, the relative reduction in VAT was greater than in SAT (P < 0.05). For the DA and DR groups only, the reduction in abdominal SAT (similar to 27%) was greater (P < 0.95) than that observed for the gluteal-femoral region (similar to 20%). Conversely, the reduction in VAT was uniform throughout the abdomen regardless of treatment (P > 0.05). MRI-LT and MRI-SM decreased both in the upper and lower body regions for the DO group alone (P < 0.05). Peak O-2 uptake (liters) was significantly improved (similar to 14%) in the DA group as was muscular strength (similar to 20%) in the DR group (P < 0.01). These findings indicate that DA and DR result in a greater preservation of MRI-SM, mobilization of SAT from the abdominal region, by comparison with the gluteal-femoral region, and improved functional capacity when compared with DO in obese men.
