背景资料：评估抗阻训练对老年男性循环中鸢尾素浓度的影响，并研究抗阻训练诱导的鸢尾素变化与体脂之间的关系。研究方法：17名老年人（平均年龄62.1岁）随机分为老年对照组（男性，n = 7）和老年训练组（男性，n = 10）。对照组不进行任何运动干预。抗阻训练组进行2次/wk的下肢肌力和核心力量训练，每次55 min，共12周。干预前后分别测定血清鸢尾素水平和身体成分。结果如下：干预12周后，抗阻训练组血清鸢尾素水平显著升高（P < 0.01），而对照组无显著变化。在抗阻训练组中，全身脂肪百分比的降低与血清鸢尾素水平的升高呈负相关（r =-0.705，P < 0.05）。结论：12周干预后，老年人循环中的鸢尾素水平显著升高。总之，血清鸢尾素可能参与老年男性体脂的调节。
Background: To assess the effects of resistance training on circulating irisin concentration in older male adults, and to investigate the association between resistance training induced alteration of irisin and body fat. Methods: Seventeen older adults (mean age is 62.1 years old) were randomized into old control group (male, n = 7), and old training group (male, n = 10). The control group has no any exercise intervention. The resistance training group underwent leg muscle strength and core strength training program two times/wk, 55 min/class for 12 weeks. Before and after the intervention, we evaluated serum irisin level and body composition. Results: Serum irisin level was significantly increased in the resistance training group after the 12 weeks intervention period (P < 0.01), but not in the control group. In the resistance training group, the reduction in whole-body fat percent was negatively correlated with the increase in serum irisin level (r = −0.705, P < 0.05). Conclusion: After the 12 weeks intervention, circulating irisin levels were significantly elevated in the older adults. In summary, serum irisin may be involved in the regulation of body fat in older male adults.
