Acute effects of high-intensity interval training session and endurance exercise on pulmonary function and cardiorespiratory coupling
Arce-Alvarez, A.; Del Rio, R.; Izquierdo, M.; Andrade, David C. [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Chile]; Parada, F. [Univ Mayor, Chile]; Uribe, S. [Univ Mayor, Chile]; Gordillo, P. [Univ Mayor, Chile] (Chile. Universidad Mayor, 2020)The aim of this study was to determine the acute effects of high-intensity interval training (HIIT) exercise and endurance exercise (EE) on pulmonary function, sympathetic/parasympathetic balance, and cardiorespiratory ... -
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 ... -
Cardiac remodeling and arrhythmogenesis are ameliorated by administration of Cx43 mimetic peptide Gap27 in heart failure rats
Andrade, David C. [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Chile]; Lucero, Claudia M.; Toledo, Camilo; Díaz, Hugo S.; Pereyra, Katherin V.; Díaz-Jara, Esteban; Schwarz, Karla G.; Marcus, Noah J.; Retamal, Mauricio A.; Quintanilla, Rodrigo A.; Del Río, Rodrigo (Springer Nature, 2020)Alterations in connexins and specifically in 43 isoform (Cx43) in the heart have been associated with a high incidence of arrhythmogenesis and sudden death in several cardiac diseases. We propose to determine salutary ... -
Effect of High-Intensity Interval Training on Body Composition, Cardiorespiratory Fitness, Blood Pressure, and Substrate Utilization During Exercise Among Prehypertensive and Hypertensive Patients With Excessive Adiposity
Delgado-Floody, Pedro; Izquierdo, Mikel; Ramírez-Velez, Robinson; Caamano-Navarrete, Felipe; Moris, Roberto; Jerez-Mayorga, Daniel; Andrade, David C. [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Chile]; Alvarez, Cristian (Frontiers Media S.A., 2020-10)Regular exercise training is a recognized lifestyle strategy to lower resting blood pressure (BP), but little is known about substrate metabolism in population with high BP. Thus, the purpose of this study was to investigate ... -
Effects of Plyometric Jump Training on Vertical Jump Height of Volleyball Players: A Systematic Review with Meta-Analysis of Randomized-Controlled Trial
Ramírez-Campillo, Rodrigo [Univ Mayor, Ctr Invest Fisiol Ejercicio, Chile]; Andrade, David C. [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Chile]; Nikolaidis, Pantelis T.; Moran, Jason; Clemente, Filipe Manuel; Chaabene, Helmi; Comfort, Paul (Department of Sports Medicine, Medical Faculty of Uludag University, 2020-09)This meta-analysis aimed to assess the effects of plyometric jump training (PJT) on volleyball players' vertical jump height (VJH), comparing changes with those observed in a matched control group. A literature search in ... -
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 ... -
Running Footwear with Custom Insoles for Pressure Distribution Are Appropriate to Diminish Impacts After Shin Splints
Henríquez, Hugo; Andrade, David C. [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Chile]; Yañez, Aquiles [Univ Mayor, Fac Ciencias, Ctr Invest Fisiol Ejercicio, Chile]; De la Fuente, Carlos (Chile. Universidad Mayor, 2019)Background: It is unknown whether the use of cushioned footwear with custom insoles for 10-km runners with shin splints if effective in attenuation of running impact. Objectives: The aim of this study was to determine the ...
