A multi-center comparison of vO2peak trainability between interval training and moderate intensity continuous training
(Journal article; Peer reviewed, 2019)There is heterogeneity in the observed VO2peak response to similar exercise training, and different exercise approaches produce variable degrees of exercise response (trainability). The aim of this study was to combine ... -
A single simulated heliox dive modifies endothelial function in the vascular wall of ApoE knockout male rats more than females
(Journal article; Peer reviewed, 2019)Introduction: The number of divers is rising every year, including an increasing number of aging persons with impaired endothelial function and concomitant atherosclerosis. While diving is an independent modulator of ... -
Absent exercise-induced improvements in fat oxidation in women with polycystic ovary syndrome after high-intensity interval training
(Peer reviewed; Journal article, 2021)Background: Polycystic ovary syndrome (PCOS) and metabolic inflexibility are linked to insulin resistance, and women with PCOS appear to be metabolic inflexible in the rested, insulin-stimulated state. Exercise training ... -
Acute effects on the human peripheral blood transcriptome of decompression sickness secondary to scuba diving
(Peer reviewed; Journal article, 2021)Decompression sickness (DCS) develops due to inert gas bubble formation in bodily tissues and in the circulation, leading to a wide range of potentially serious clinical manifestations. Its pathophysiology remains incompletely ... -
Aerobic and anaerobic speed predicts 800-m running performance in young recreational runners
(Peer reviewed; Journal article, 2021)The main aim was to investigate the impact of maximal aerobic speed (MAS), maximal anaerobic speed (MANS), and time to exhaustion (TTE) at 130% MAS, on 800-m running time performance (800TT). A second aim was to investigate ... -
Aerobic Interval Training Prevents Age-Dependent Vulnerability to Atrial Fibrillation in Rodents
(Journal article; Peer reviewed, 2018)Aims: Increasing age is the most important risk factor for atrial fibrillation (AF). Very high doses of exercise training might increase AF risk, while moderate levels seem to be protective. This study aimed to examine the ... -
The Assessment of Daily Energy Expenditure of Commercial Saturation Divers using Doubly Labelled Water
(Peer reviewed; Journal article, 2021)Commercial saturation divers are exposed to unique environmental conditions and are required to conduct work activity underwater. Consequently, divers’ physiological status is shown to be perturbed and therefore, appropriate ... -
Blood gene expression and vascular function biomarkers in professional saturation diving
(Journal article; Peer reviewed, 2018)Saturation diving is an established way to conduct subsea operations with human intervention. While working, the divers must acclimatize to the hyperbaric environments. In this study, genome-wide gene expression and selected ... -
Can Gaming Get You Fit?
(Peer reviewed; Journal article, 2020)Rationale: Exergaming may be a viable alternative to more traditional exercise. As high-intensity exercise can provide substantial health benefits, the purpose of this study was to investigate the long-term effectiveness ... -
Characterization of Electrical Activity in Post-myocardial Infarction Scar Tissue in Rat Hearts Using Multiphoton Microscopy
(Journal article; Peer reviewed, 2018)Background: The origin of electrical behavior in post-myocardial infarction scar tissue is still under debate. This study aims to examine the extent and nature of the residual electrical activity within a stabilized ... -
Circulating and Adipose Tissue miRNAs in Women With Polycystic Ovary Syndrome and Responses to High-Intensity Interval Training
(Peer reviewed; Journal article, 2020)MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression post-transcriptionally. In women with polycystic ovary syndrome (PCOS), several miRNAs are differentially expressed compared to women without PCOS, ... -
Comparison of Mitochondrial Respiration in M. triceps brachii and M. vastus lateralis Between Elite Cross-Country Skiers and Physically Active Controls
(Journal article; Peer reviewed, 2019)Rationale: The main purposes of this study were to compare mitochondrial respiration in M. triceps brachii and M. vastus lateralis between elite cross-country (XC) skiers and physically active controls (CON), and to explore ... -
Continuous hemodynamic monitoring in an intact rat model of simulated diving
(Journal article; Peer reviewed, 2020)Cardiovascular risk is elevated in divers, but detailed information of cardiac function during diving is missing. The aim of this study was to apply an intact rat model with continuous monitoring of cardiac left ventricular ... -
Effects of cold decompression on hemodynamic function and DCS risk in a dry diving rat model
(Peer reviewed; Journal article, 2021)Background: Diving in cold water is thought to increase the risk of decompression sickness (DCS), especially if the diver is cold during decompression. In this study, we investigated hemodynamic function and DCS risk in ... -
Effects of individual changes in training distribution on maximal aerobic capacity in well-trained cross-country skiers: A follow-up study
(Peer reviewed; Journal article, 2021)The purpose of this study was to evaluate individual changes in training distribution and the subsequent effects on maximal oxygen uptake (VO2max). The participants were well-trained cross-country skiers who had performed ... -
Evaluation of Divers’ Neuropsychometric Effectiveness and High-Pressure Neurological Syndrome via Computerized Test Battery Package and Questionnaires in Operational Setting
(Peer reviewed; Journal article, 2019)Introduction: When divers are compressed to water depths deeper than 150 meter sea water (msw), symptoms of high-pressure neurological syndrome (HPNS) might appear due to rapid increase in pressure on the central nervous ... -
Exercise interventions in polycystic ovary syndrome: A systematic review and meta-analysis
