To analyze the body fat (BF) content and distribution modifications in coronary artery disease (CAD) patients in response to a 1-year combined aerobic and resistance exercise training (CET) program.
We followed two groups of CAD male patients for 12 months. One group consisted of 17 subjects (57 ± 12 years) who engaged in a CET program (CET group) and the other was a age-matched control group of 10 subjects (58 ± 11 years). BF content and distribution were measured through dual energy X-ray absorptiometry (DXA) at baseline and follow-up.
We found no differences on body mass and BMI between baseline and end of follow-up in both groups but, in CET group, we found significant reductions in all analyzed BF depots, including total BF (21.60 ± 6.00 vs. 20.32 ± 5.89 kg, P < 0.01), % total BF (27.8 ± 5.5 vs. 26.4 ± 5.4%, P < 0.05), trunk fat (12.54 ± 3.99 vs. 11.77 ± 4.01 kg, P < 0.05), % trunk fat (31.1 ± 6.9 and 29.2 ± 7.1%, P < 0.05), appendicular fat (8.22 ± 2.08 vs. 7.72 ± 2.037 kg, P < 0.01), % appendicular fat (25.7 ± 4.9 and 24.5 ± 4.9%, P < 0.05), and abdominal fat (2.95 ± 1.06 vs. 2.75 ± 1.10 kg, P < 0.05). Control group showed significant increase in appendicular fat (7.63 ± 1.92 vs. 8.10 ± 2.12 kg, P < 0.05).
These results confirm the positive effect of CET on body composition of CAD patients, despite no changes in body mass or BMI. In this study, we observed no alterations on BF distribution meaning similar rate of fat loss in all analyzed BF depots. These results also alert for the limitations of BMI for tracking body composition changes.
分析冠心病(CAD)患者在接受为期 1 年的有氧和抗阻运动训练(CET)方案后体脂(BF)含量和分布的变化。
我们对两组 CAD 男性患者进行了 12 个月的随访。一组包括 17 名受试者(57 ± 12 岁),他们参加了 CET 方案(CET 组),另一组是年龄匹配的对照组,共 10 名受试者(58 ± 11 岁)。基线和随访时,通过双能 X 射线吸收法(DXA)测量 BF 含量和分布。
两组在基线和随访结束时的体重和 BMI 均无差异,但在 CET 组,我们发现所有分析的 BF 部位均显著减少,包括总 BF(21.60 ± 6.00 与 20.32 ± 5.89 kg,P < 0.01)、总 BF%(27.8 ± 5.5 与 26.4 ± 5.4%,P < 0.05)、躯干脂肪(12.54 ± 3.99 与 11.77 ± 4.01 kg,P < 0.05)、躯干脂肪%(31.1 ± 6.9 和 29.2 ± 7.1%,P < 0.05)、四肢脂肪(8.22 ± 2.08 与 7.72 ± 2.037 kg,P < 0.01)、四肢脂肪%(25.7 ± 4.9 和 24.5 ± 4.9%,P < 0.05)和腹部脂肪(2.95 ± 1.06 与 2.75 ± 1.10 kg,P < 0.05)。对照组四肢脂肪显著增加(7.63 ± 1.92 与 8.10 ± 2.12 kg,P < 0.05)。
这些结果证实了 CET 对 CAD 患者身体成分的积极影响,尽管体重或 BMI 没有变化。在这项研究中,我们观察到 BF 分布没有改变,这意味着所有分析的 BF 部位的脂肪损失率相似。这些结果还提醒人们,BMI 对跟踪身体成分变化的局限性。
