摘要

导言:2型糖尿病(DM2)可导致自主神经系统功能紊乱,心率变异性(HRV)通常用于评估该系统在休息和体育锻炼时的功能:目的:评估DM2患者在静息状态下的自律神经调节以及心率和副交感神经指数对等长手握运动的反应:样本包括 40 岁以上的男女患者,分为确诊为 DM2 和未确诊为 DM2 两组。静息心率变异的采集在仰卧位进行,持续 20 分钟,选取 256 个点进行符号和线性分析。这些人进行了一分钟等长收缩,收缩强度分别为最大收缩强度的 10%、20%、30%、40% 和 50%,使用副交感神经指数 RMSSD 和 SD1 进行分析:静息时心率变异的线性指数和符号指数与运动时获得的指数相似(P 值大于 0.05)。结果:静息时的心率变异线性指数和符号指数与运动时获得的指数相似(P值>0.05),静息时的指数与运动时的反应之间没有关联,但发现糖尿病患者的心率和副交感神经指数反应略有延迟:结论:各组之间在静息状态的调节和运动时副交感神经的调整方面没有差异(参考文献 32,表 4)。

Complexity and heart rate adjustments of diabetic people during isometric contraction.

Ntroduction: Type 2 Diabetes Mellitus (DM2) can lead to autonomic nervous system dysfunction and heart rate variability (HRV) is often used to assess this system both during rest and during physical exercise.

Objective: To evaluate the autonomic modulation at rest and the responses of heart rate and parasympathetic indices of individuals with DM2 to isometric handgrip exercise.

Method: The sample consisted of individuals of both sexes; over 40 years, divided into groups, with and without DM2 diagnosis. The collection of resting HRV was performed for 20 minutes in the supine position, and 256 points were selected for symbolic and linear analysis. The individuals performed isometric contraction for one minute with intensities of 10, 20, 30, 40 and 50 % of the maximum contraction, using the parasympathetic indexes RMSSD and SD1 for analysis.

Results: Linear and symbolic indices of HRV at rest and those obtained during exercise were similar (p-value>0.05). No association was found between the indices at rest and the responses to exercise, with a slight delay in the response of diabetics in HR and parasympathetic indices being identified.

Conclusion: There was no difference between the groups in the modulation of rest or in the parasympathetic adjustments of the exercise (Tab. 4, Ref. 32).
