Bitter Orange Intake Before Submaximal Aerobic Exercise Is Safe for Cardiovascular and Autonomic Systems in Healthy Males: A Randomized Trial.

Background: There are still no studies of the cardiovascular safety of the isolated use of in aerobic submaximal exercise.

Objective: To evaluate the effect of supplementation on the recovery of cardiorespiratory and autonomic parameters following a session of submaximal aerobic exercise.

Methods: Twelve healthy male adults achieved a crossover, randomized, double-blind, and placebo-controlled trial.

Poincaré plot analysis of ultra-short-term heart rate variability during recovery from exercise in physically active men.

Background: Recently there has been increasing interest in the study of ultra-short-term heart rate variability (HRV) in sports performance and exercise physiology. In order to improve standardization of this specific analysis, we evaluated the ultra-short-term HRV analysis through SD1Poincaré Index to identify exercise induced responses.

Methods: We investigated 35 physically active men aged between 18 and 35 years old.

Musical Auditory Stimulation Influences Heart Rate Autonomic Responses to Endodontic Treatment.

We aimed to evaluate the acute effect of musical auditory stimulation on heart rate autonomic regulation during endodontic treatment. The study included 50 subjects from either gender between 18 and 40 years old, diagnosed with irreversible pulpitis or pulp necrosis of the upper front teeth and endodontic treatment indication. HRV was recorded 10 minutes before (T1), during (T2), and immediately (T3 and T4) after endodontic treatment.

Non-linear indices of heart rate variability during endodontic treatment.

Dental treatment promotes psychosomatic change that can influence the procedure and compromise the general well-being of the patient. In this context, it highlights the importance of evaluating the function of the autonomic nervous system in individuals undergoing endodontic treatment. Thus, this manuscript aimed to analyse cardiac autonomic modulation, through non-linear indices of heart rate variability (HRV) during endodontic treatment.

Association between oral variables and heart rate variability.

The heart rate variability is a useful method to assess cardiac autonomic modulation in patients undergoing dental procedures, because knowledge of physiological conditions provides greater security to the professional as well as the possibility of a better plan treatment to patient benefit. The aim of our study was to describe the association between cardiac autonomic control and dental variables. We consulted the databases Medline, SciELO, Lilacs and Cochrane, using the terms "autonomic", "dentistry", "heart rate variability", "cardiovascular physiology.
