The aim of the present study was to investigate the effects of inspiratory muscle exercise (IME) on metabolic and hemodynamic parameters, cardiac autonomic modulation and respiratory function of older women with metabolic syndrome (MS). For this, sixteen older women with MS and 12 aged-matched controls participated of the present study. Two days before and 2 days after the main experiment, fasting blood samples (i.e., total cholesterol, triglycerides and blood glucose), cardiac autonomic modulation (i.e., heart rate variability), and respiratory muscle function were obtained and evaluated. The sessions of physical exercise was based on a IME, which was performed during 7 days. Each session of IME was performed during 20 min, at 30% of maximal static inspiratory pressure. In the results, MS group presented higher levels of triglycerides, blood glucose, and systolic blood pressure when compared to control group. IME was not able to change these variables. However, although MS group showed impaired respiratory muscle strength and function, as well as cardiac autonomic modulation, IME was able to improve these parameters. Thus, the data showed that seven days of IME are capable to improve respiratory function and cardiac autonomic modulation of older women with MS. These results indicate that IME can be a profitable therapy to counteracting the clinical markers of MS, once repeated sessions of acute IME can cause chronical alterations on respiratory function and cardiac autonomic modulation.
本研究的目的是调查吸气肌锻炼（IME）对患有代谢综合征（MS）的老年女性的代谢和血流动力学参数、心脏自主神经调节及呼吸功能的影响。为此，16名患有MS的老年女性和12名年龄匹配的对照者参与了本研究。在主要实验前2天和后2天，采集并评估空腹血样（即总胆固醇、甘油三酯和血糖）、心脏自主神经调节（即心率变异性）及呼吸肌功能。体育锻炼课程基于吸气肌锻炼，为期7天。每次吸气肌锻炼课程持续20分钟，强度为最大静态吸气压力的30%。结果显示，与对照组相比，MS组的甘油三酯、血糖和收缩压水平更高。吸气肌锻炼未能改变这些变量。然而，尽管MS组的呼吸肌力量和功能以及心脏自主神经调节受损，但吸气肌锻炼能够改善这些参数。因此，数据表明，7天的吸气肌锻炼能够改善患有MS的老年女性的呼吸功能和心脏自主神经调节。这些结果表明，吸气肌锻炼可能是一种有益的疗法，可对抗代谢综合征的临床指标，因为重复进行急性吸气肌锻炼可导致呼吸功能和心脏自主神经调节的慢性改变。
