摘要

在衰老过程中，合成代谢状态对于防止骨骼肌质量和数量的下降至关重要。运动调节肌肉状态的内分泌标记物。我们研究了62名年龄在30-70岁的非肌肉减少的墨西哥成年游泳运动员的肌肉状态内分泌标志物的差异，他们被分为两组:系统训练组(ST)包括身体活动水平(PAL) bbb1.6的运动员，以及非系统训练组(NST)由PAL <1.5的参与者组成。分析体成分、饮食、生化及内分泌指标。ST组表现出较低的肌生长抑制素(MSTN)和鸢尾素(IRI)水平，这是SMM的两种强调节因子。胰岛素生长因子-1 (IGF-1)在st中较高，这与大多数年轻运动员和阻力训练项目的证据一致，其中IGF-1和IRI似乎在维持高级运动员的合成代谢状态中起着至关重要的作用。

Systematic training in master swimmer athletes increases serum insulin growth factor-1 and decreases myostatin and irisin levels

Abstract During ageing, anabolic status is essential to prevent the decrease in quantity and quality of skeletal muscle mass (SMM). Exercise modulates endocrine markers of muscle status. We studied the differences of endocrine markers for muscle status in 62 non-sarcopenic Mexican swimmer adults aged 30–70 y/o, allocated into two groups: the systematic training (ST) group including master athletes with a physical activity level (PAL) >1.6, and the non-systematic training group (NST) composed by subjects with a PAL <1.5. Body composition, diet, biochemical and endocrine markers were analyzed. The ST group showed lower myostatin (MSTN) and irisin (IRI) levels, two strong regulators of SMM. The insulin growth factor-1 (IGF-1) was higher in the ST. This is consistent with most of the evidence in young athletes and resistance training programs, where IGF-1 and IRI seem to play a crucial role in maintaining anabolic status in master athletes.
