Effects of Plyometric Training on Explosive and EnDuránce Performance at Sea Level and a High Altitude
Cristobal Andrade, David [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Santiago, Chile]; Rosa Beltrán, Ana; Labarca-Valenzuela, Cristián; Manzo-Botarelli, Oscar; Trujillo, Erwin; Otero-Farias, Patricio; Alvarez, Cristián; García-Hermoso, Antonio; Toledo, Camilo; Del Rio, Rodrigo; Silva-Urra, Juan; Ramírez-Campillo, Rodrigo (FRONTIERS MEDIA SA, 2018)Plyometric training performed at sea level enhance explosive and enDuránce performance at sea level. However, its effects on explosive and enDuránce performance at high altitude had not been studied. Therefore, the aim of ... -
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), ... -
Intranasal oxytocin increases respiratory rate and reduces obstructive event duration and oxygen desaturation in obstructive sleep apnea patients: a randomized double blinded placebo controlled study
Jain, Vivek; Kimbro, Shawn; Kowalik, Grant; Milojevic, Ivana; Dowling, N. Maritza; Hunley, Anne Lloyd; Hauser, Kelsey; Andrade, David C. [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Chile]; Del Rio, Rodrigo; Kay, Matthew W.; Mendelowitz, David (Elsevier, 2020-10)Background: Activation of the oxytocin network has shown benefits in animal models of Obstructive Sleep Apnea (OSA) as well as other cardiorespiratory diseases. We sought to determine if nocturnal intranasal oxytocin ... -
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 ... -
Ventilatory and Autonomic Regulation in Sleep Apnea Syndrome: A Potential Protective Role for Erythropoietin?
Andrade, David C. [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Santiago, Chile]; Haine, Liasmine; Toledo, Camilo; Díaz, Hugo S.; Quintanilla, Rodrigo A.; Marcus, Noah J.; Iturriaga, Rodrigo; Richalet, Jean-Paul; Voituron, Nicolás; Del Rio, Rodrigo (FRONTIERS MEDIA SA, 2018)Obstructive sleep apnea (OSA) is the most common form of sleep disordered breathing and is associated with wide array of cardiovascular morbidities. It has been proposed that during OSA, the respiratory control center (RCC) ...
