Journal ArticleDOI
Training‐induced acceleration of O2 uptake on‐kinetics precedes muscle mitochondrial biogenesis in humans
Jerzy A. Zoladz,Bruno Grassi,Joanna Majerczak,Zbigniew Szkutnik,Michal Korostynski,J Karasinski,Wincenty Kilarski,Bernard Korzeniewski +7 more
TL;DR: It is demonstrated that 5 weeks of moderate‐intensity training accelerates the on‐kinetics during moderate‐ intensity cycling in the absence of enhanced mitochondrial biogenesis or capillarization in the trained muscles.
Journal ArticleDOI
Detection of the change point in oxygen uptake during an incremental exercise test using recursive residuals : relationship to the plasma lactate accumulation and blood acid base balance
TL;DR: It was shown that in 25 out of 26 subjects it was possible to determine the CP-O2 as described in the model, and an additional increase in V˙O2 above the values expected from the linear model was allowed.
Journal ArticleDOI
Mechanisms responsible for the acceleration of pulmonary V̇O2 on-kinetics in humans after prolonged endurance training.
Jerzy A. Zoladz,Bruno Grassi,Joanna Majerczak,Zbigniew Szkutnik,Michal Korostynski,Marcin Grandys,Wieslawa Jarmuszkiewicz,Bernard Korzeniewski +7 more
TL;DR: By applying to the experimental data, the computer model of oxidative phosphorylation (OXPHOS) and using metabolic control analysis, it is argued that COX activity is a much better measure of OXPHOS intensity than CS activity.
Journal ArticleDOI
Preexercise metabolic alkalosis induced via bicarbonate ingestion accelerates Vo2 kinetics at the onset of a high-power-output exercise in humans.
TL;DR: The present study investigated the effect of preexercise metabolic alkalosis on the primary component of oxygen uptake (Vo(2)) kinetics, characterized by tau(1), found to be significantly reduced during cycling at 87% of Vo(2 max), which was significantly different from zero with both the Student's t-test and the Wilcoxon's signed-ranks test.
Journal ArticleDOI
Endurance training decreases the non‐linearity in the oxygen uptake–power output relationship in humans
TL;DR: It is concluded that the training‐induced increase in power‐generating capabilities at was due to attenuation of the ‘excess’ above the LT, and this adaptive response seems to be related to the improvement of muscle metabolic stability, as judged by a lowering of plasma ammonia concentration.
