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.

Effects of transcranial direct current stimulation on heart rate variability: a systematic review protocol.

Objective: This systematic review aims to synthesize the available evidence on the effects of transcranial direct current stimulation on heart rate modulation, indexed by heart rate variability parameters in healthy individuals and those with clinical disorders.

Introduction: There is some evidence that altered heart rate variability parameters are associated with different clinical disorders. For example, diminished parasympathetic activity has been explored as a potential biomarker for some chronic pain conditions.
