Abstract

Obesity has a complex multifactorial etiology and is characterized by excessive accumulation of adipose tissue. Visceral adipose tissue has deleterious effects on health because it secretes large amounts of inflammatory cytokines. Nutritional calorie restriction associated with strength training may be useful in managing chronic systemic inflammation. This study aimed to evaluate the acute effect of a single strength-training session on plasma adipokine levels in sedentary, overweight, and obese young men. This study included twelve men (Age: [34.95 ​± ​9.77] years; Height: [174.16 ​± ​3.66] centimeter [cm]; Weight: [97.83 ​± ​12.87] kilogram (kg); body mass index [BMI]: [32.30 ​± ​4.51] kg/m2), who performed a single strength training session. The strength training protocol consisted of 4 sets of 12 repetitions in the following six exercises, 45° leg press, bench press, leg extension, machine row, leg curl, and shoulder press. Blood samples were collected before, immediately after, and 1-h subsequent after strength training. The plasma levels of resistin and leptin were measured. A significant decrease in resistin levels were found 1 ​h after the strength training session if compared to levels before the training session (pre-[before] [2 390 ​± ​1 199] picograms per milliliter [pg/mL] vs post-1 h [1-h subsequent] [1 523 ​± ​798],6 ​pg/mL, p ​= ​0.002 8). The plasma leptin levels did not differ at any time point. In conclusion, a very well controlled single session of strength training significantly decreased the plasma levels of resistin without altering the concentration of leptin in overweight and obese individuals. This effect, at least in part, supports the benefits of exercise by reducing the low grade inflammation and insulin resistance in obesity.

单次力量训练可改变超重和肥胖男性的血浆抵抗素水平,但不会改变瘦素水平
肥胖症有着复杂的多因素病因,其特点是脂肪组织过度堆积。内脏脂肪组织会分泌大量的炎症细胞因子,从而对健康产生有害影响。与力量训练相结合的营养热量限制可能有助于控制慢性全身性炎症。本研究旨在评估单次力量训练对久坐、超重和肥胖年轻男性血浆脂肪因子水平的急性影响。这项研究包括 12 名男性(年龄:[34.95 ± 9.77] 岁;身高:[174.16 ± 3.66] 厘米[cm];体重:[97.83 ± 12.87] 千克(kg);体重指数[BMI]:[32.30±4.51]千克/平方米),进行单次力量训练。力量训练方案包括以下六种练习,45°压腿、卧推、腿部伸展、器械划船、腿部卷曲和肩部推举,每组 12 次。分别在力量训练前、训练后和训练后 1 小时采集血液样本。测量血浆中的抵抗素和瘦素水平。与训练前的水平相比,力量训练 1 小时后的抵抗素水平明显下降(训练前 [前] [2 390 ± 1 199] 皮克/毫升 [pg/mL] vs 训练后 1 小时 [1 小时后] [1 523 ± 798],6 pg/毫升,p = 0.002 8)。血浆瘦素水平在任何时间点都没有差异。总之,在超重和肥胖人群中,控制非常好的单次力量训练可显著降低血浆中的抵抗素水平,而不会改变瘦素的浓度。这种效果至少在一定程度上支持了运动通过减少低度炎症和肥胖症的胰岛素抵抗而带来的益处。
