Exercise mitigates the loss of muscle mass by attenuating the activation of autophagy during severe energy deficit
Martin-Rincon, Marcos; Pérez-López, Antonio; Morales-Alamo, David; Perez-Suarez, Ismael; de Pablos-Velasco, Pedro; Perez-Valera, Mario; Perez-Regalado, Sergio; Martinez-Canton, Miriam; Gelabert-Rebato, Miriam; Juan-Habib, Julian William; Holmberg, Hans-Christer; Calbet, Jose Antonio Lopez (Peer reviewed; Journal article, 2019)The loss of skeletal muscle mass with energy deficit is thought to be due to protein breakdown by the autophagy-lysosome and the ubiquitin-proteasome systems. We studied the main signaling pathways through which exercise ... -
Fast regulation of the NF-κB signalling pathway in human skeletal muscle revealed by high-intensity exercise and ischaemia at exhaustion: Role of oxygenation and metabolite accumulation
Gallego-Selles, Angel; Galvan-Alvarez, Victor; Martinez-Canton, Miriam; Garcia-Gonzalez, Eduardo; Morales-Alamo, David; Santana, Alfredo; Gonzalez-Henriquez, Juan Jose; Dorado, Cecilia; Calbet, Jose Antonio Lopez; Martin-Rincon, Marcos (Peer reviewed; Journal article, 2022)The NF-κB signalling pathway plays a critical role in inflammation, immunity, cell proliferation, apoptosis, and muscle metabolism. NF-κB is activated by extracellular signals and intracellular changes in Ca2+, Pi, H+, ... -
Functional reserve and sex differences during exercise to exhaustion revealed by post-exercise ischaemia and repeated supramaximal exercise
Martin-Rincon, Marcos; Gelabert-Rebato, Miriam; Perez-Valera, Mario; Galvan-Alvarez, Victor; Morales-Alamo, David; Dorado, Cecilia; Boushel, Robert; Hallén, Jostein; Calbet, José Antonio López (Peer reviewed; Journal article, 2021)The purpose of this study was to ascertain what mechanisms explain sex differences at task failure and to determine whether males and females have a functional reserve at exhaustion. Exercise performance, cardiorespiratory ... -
Impact of data averaging strategies on V̇O2max assessment: Mathematical modeling and reliability
Martin-Rincon, Marcos; Gonzalez-Henriquez, Juan Jose; Losa-Reyna, Jose; Perez-Suarez, Ismael; Ponce-Gonzalez, Jesus Gustavo; de La Calle-Herrero, Jaime; Perez-Valera, Mario; Perez-Lopez, Alberto; Curtelin, David; Cherouveim, Evgenia D; Morales-Alamo, David; Calbet, Jose Antonio Lopez (Peer reviewed; Journal article, 2019)Background: No consensus exists on how to average data to optimize VO2max assessment. Although the VO2max value is reduced with larger averaging blocks, no mathematical procedure is available to account for the effect of ... -
An integrative approach to the regulation of mitochondrial respiration during exercise: Focus on high-intensity exercise
Calbet, Jose Antonio Lopez; Martín-Rodríguez, Saúl; Martin-Rincon, Marcos; Morales-Alamo, David (Peer reviewed; Journal article, 2020)During exercise, muscle ATP demand increases with intensity, and at the highest power output, ATP consumption may increase more than 100-fold above the resting level. The rate of mitochondrial ATP production during exercise ... -
