VO2 kinetics is an important determinant of aerobic performance because \nfast VO2 kinetics will lead to less O2 deficit at the onset of exercise. Pre-cooling of working \nmuscles prior to exercise has been shown to slow the VO2 kinetic response to exercise but is \nnot clear if cold environment without muscle pre-cooling has an effect on VO2 kinetics. There \nis currently only one study examining the effects of training in the cold on aerobic performance \nand mitochondrial biogenesis. Therefore, the aim of this study was to examine the effects of \ntraining in the cold on oxygen uptake and cardiovascular hemodynamics kinetics as well as \naerobic performance.\n37 untrained individuals aged 20-35 (51 % female) took part in a training intervention. 18 \nparticipants were randomly assigned to train in a climatic chamber set at 0 \u00b0C and 19 \nparticipants were randomly assigned to train in room temperature (~ 22\u00b0C). 15 participants form \ncold group and 19 participants from thermoneutral completed the 7-week high-intensity interval \ntraining intervention (3 training sessions/week). Before and after the training intervention, \nkinetics of VO2, heart rate (HR), stroke volume (SV), and cardiac output (CO) during moderate \nexercise as well as muscle blood flow and peak oxygen consumption (VO2peak) were assessed. \nThe effects of training temperature on training adaptations were assessed comparing differences \nbetween the groups after training. The effects of the training intervention were studied \ncomparing pre and post measurements and correlations between kinetic variables and changes \nin these variables were assessed to see what factors affected aerobic performance and \nadaptations to training.\nThe results of this study showed that training in the cold did not affect training-induced \nadaptations of maximal aerobic performance (VO2peak and maximal cycling power), muscle \nblood flow or kinetics of VO2, HR, SV, and CO. However, the training intervention improved \nmaximal aerobic performance and the rate of VO2 and HR kinetics. HR and CO kinetics \ncorrelated with maximal aerobic performance before and after training but VO2 kinetics did \nnot. Also, the change in VO2 kinetics did not correlate with the change in maximal aerobic \nperformance. The lack of difference between the groups indicates that training in the cold does \nnot deteriorate training adaptations and there likely were no differences in muscle temperature \nbetween the groups during training. VO2 kinetics were faster after training and the improvement \nin the rate of VO2 kinetics is likely attributable to changes in activation of oxidative metabolism.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2021-06-09T05:43:32Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-06-09T05:43:32Z (GMT).
