我们比较了适度的低热量，高蛋白质饮食和阻力训练，使用两种不同的蛋白质补充剂，与低热量饮食单独对超重警察的身体成分变化的影响。我们进行了一项为期12周的随机前瞻性研究，比较了三个研究组中三种不同治疗方式所产生的身体成分变化。一组（n = 10）被放置在一个非脂肪生成，低热量的饮食赎罪（80%的预测需求）。第二组（n = 14）被放置在低热量饮食加阻力运动加高蛋白摄入量（1.5克/公斤/天）使用酪蛋白水解物。在第三组（n = 14）中，除了使用乳清蛋白水解物之外，处理与第二组相同。我们发现所有三组的体重减轻约2.5 kg。在12周时，单独饮食的平均体脂百分比从基线27 +/-1.8%降至25 +/- 1.3%。饮食，运动和酪蛋白的下降从26 +/- 1.7到18 +/- 1.1%，饮食，运动和乳清蛋白的下降从27 +/- 1.6到23 +/-1.3%。三组的平均脂肪损失分别为2.5 +/- 0.6、7.0 +/- 2.1和4.2 +/- 0.9 kg。三组中的瘦体重增加在单独饮食中没有变化，而酪蛋白和乳清组分别增加了4 +/- 1.4和2 +/- 0.7 kg。酪蛋白组胸部、肩部和腿部力量平均增加59 +/- 9%，乳清组增加29 +/- 9%，组间差异显著。身体组成和力量的这种显著差异可能是由于酪蛋白水解产物的肽组分引起的氮保留和整体抗分解作用的改善。版权所有（C）2000 S.

We compare the effects of a moderate hypocaloric, high-protein diet and resistance training, using two different protein supplements, versus hypocaloric diet alone on body compositional changes in overweight police officers. A randomized, prospective 12-week study was per formed comparing the changes in body composition produced by th ree different treatment modalities in th ree study groups. One group (n = 10) was placed on a non-lipogenic, hypocaloric diet atone (80% of predicted needs). A second group (n = 14) was placed on the hypocaloric diet plus resistance exercise plus a high-protein intake (1.5 g/kg/day) using a casein protein hydrolysate. In the third group (n = 14) treatment was identical to the second, except for the use of a whey protein hydrolysate. We found that weight loss was approximately 2.5 kg in all three groups. Mean percent body fat with diet alone decreased from a baseline of 27 +/- 1.8 to 25 +/- 1.3% at 12 weeks. With diet, exercise and casein the decrease was from 26 +/- 1.7 to 18 +/- 1.1% and with diet, exercise and whey protein the decrease was from 27 +/- 1.6 to 23 +/- 1.3%. The mean fat loss was 2.5 +/- 0.6, 7.0 +/- 2.1 and 4.2 +/- 0.9 kg in the three groups, respectively. Lean mass gains in the three groups did not change for diet alone, versus gains of 4 +/- 1.4 and 2 +/- 0.7 kg in the casein and whey groups, respectively. Mean increase in strength for chest, shoulder and legs was 59 +/- 9% for casein and 29 +/- 9% for whey, a significant group difference. This significant difference in body composition and strength is likely due to improved nitrogen retention and overall anticatabolic effects caused by the peptide components of the casein hydrolysate.
