To determine whether, for a given body mass index (BMI), men with high cardiorespiratory fitness (CRF) have lower waist circumference (WC) and less total abdominal, abdominal subcutaneous, and visceral adipose tissue (AT) compared with men with low CRF.
Subjects were categorized into HIGH CRF (N = 169) and LOW CRF (N = 124) groups based on age and CRF measured using a maximal treadmill test. Total abdominal, abdominal subcutaneous and visceral AT were measured by computerized tomography.
For a given BMI, men in the HIGH CRF group had significantly lower WC (P < 0.001), total abdominal (P < 0.001), visceral AT (P < 0.001), and abdominal subcutaneous AT (P < 0.001) compared with men in the LOW CRF group.
These findings suggest that the ability of CRF to attenuate the health risks associated with BMI may be partially mediated through a reduction in abdominal AT. Accordingly, our observations reinforce the importance of regular physical activity in the prevention and reduction of obesity-related health risk independent of a corresponding reduction in body weight.
确定对于给定的体重指数（BMI），与心肺适能（CRF）低的男性相比，心肺适能高的男性是否具有更小的腰围（WC）以及更少的腹部总体脂肪、腹部皮下脂肪和内脏脂肪组织（AT）。
根据年龄和使用最大跑步机测试测量的CRF，将受试者分为高CRF组（N = 169）和低CRF组（N = 124）。通过计算机断层扫描测量腹部总体脂肪、腹部皮下脂肪和内脏AT。
对于给定的BMI，与低CRF组的男性相比，高CRF组的男性WC（P < 0.001）、腹部总体脂肪（P < 0.001）、内脏AT（P < 0.001）和腹部皮下AT（P < 0.001）显著更低。
这些发现表明，CRF减轻与BMI相关的健康风险的能力可能部分通过减少腹部AT来介导。因此，我们的观察结果强化了规律体育活动在预防和降低肥胖相关健康风险方面的重要性，而与体重相应减轻无关。
