Baroreflex Modulation During Acute High-Altitude Exposure in Rats
Andrade, David C. [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Chile]; Beltrán, Ana Rosa; Arce-Alvarez, Alexis; Ramírez-Campillo, Rodrigo; Vásquez-Muñoz, Manuel; Igel, Magdalena von; Ramírez, Marco A.; Del Río, Rodrigo (Frontiers Media, 2020)Baroreflex (BR) control is critically dependent of sympathetic and parasympathetic modulation. It has been documented that during acute hypobaric hypoxia there is a BR control impairment, however, the effect of a natural ... -
Heart rate variability alterations in infants with spontaneous hypertonia
Andrade, David C. [Univ Mayor, Ctr Invest Fisiol Ejercicio, Santiago, Chile]; Arce-Alvarez, Alexis; Melipillan, Claudia; Toledo, Camilo; Marcus, Noah J.; Del Rio, Rodrigo (NATURE PUBLISHING GROUP, 2019)BACKGROUND: Hypertonia is characterized by increased resting muscle tone. Previous studies have shown that adult patients with hypertonia displayed autonomic imbalance. However, cardiac sympathovagal control in infants ... -
Hypoxic Respiratory Chemoreflex Control in Young Trained Swimmers
Arce-Alvarez, Alexis; Vazquez-Munoz, Manuel; Alvares, Cristian; Izquierdo, Mikel; Millet, Gregoire P.; Del Rio, Rodrigo; Veliz, Carlos [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Chile]; von Igel, Magdalena [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Chile]; Ramirez-Campillo, Rodrigo [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Chile]; Andrade, David C. [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Chile] (FRONTIERS MEDIA SA, 2021-03-29)During an apnea, changes in PaO2 activate peripheral chemoreceptors to increase respiratory drive. Athletes with continuous apnea, such as breath-hold divers, have shown a decrease in hypoxic ventilatory response (HVR), ... -
Revisiting the physiological effects of exercise training on autonomic regulation and chemoreflex control in heart failure: does ejection fraction matter?
Andrade, David C. [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Santiago, Chile]; Arce-Alvarez, Alexis; Toledo, Camilo; Díaz, Hugo S.; Lucero, Claudia; Quintanilla, Rodrigo A.; Schultz, Harold D.; Marcus, Noah J.; Amann, Markus; Del Rio, Rodrigo (AMER PHYSIOLOGICAL SOC, 2018)Heart failure (HF) is a global public health problem that, independent of its etiology [reduced (HFrEF) or preserved ejection fraction (HFpEF)], is characterized by functional impairments of cardiac function, chemoreflex ...
