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 Including Sprints in One Weekly Low-Intensity Training Session During the Transition Period of Elite Cyclists
(Peer reviewed; Journal article, 2020)The purpose of this study was to investigate the effects of including 30-s sprints in one weekly low-intensity training (LIT) session during a 3-week transition period in elite cyclists. Sixteen male elite cyclists (maximal ... -
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 ... -
Effects of initial performance, gross efficiency and VO_2peak characteristics on subsequent adaptations to endurance training in competitive cyclists
(Journal article; Peer reviewed, 2018)The present study investigated the effects of initial levels of cycling performance, peak oxygen uptake (www.frontiersin.orgO2peak) and gross efficiency (GE) on the subsequent adaptations of these variables and their ... -
Energetic Cost and Kinematics of Pushing a Stroller on Flat and Uphill Terrain
(Peer reviewed; Journal article, 2020)During early parenthood, walking and/or running while pushing a stroller is a common form of endurance exercise among both recreationally active individuals and athletes. Here, we investigate how pushing a stroller influences ... -
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
(Peer reviewed; Journal article, 2020)Background: Polycystic ovary syndrome (PCOS) is a common and complex endocrinopathy with reproductive and metabolic manifestations. Exercise training has consistently been found to result in improved clinical outcomes in ... -
Extensive simulated diving aggravates endothelial dysfunction in male pro-atherosclerotic ApoE knockout rats
(Peer reviewed; Journal article, 2020)Introduction: The average age of the diving population is rising, and the risk of atherosclerosis and cardiovascular disease in divers are accordingly increasing. It is an open question whether this risk is altered by ... -
Factors Influencing Running Velocity at Lactate Threshold in Male and Female Runners at Different Levels of Performance
(Peer reviewed; Journal article, 2020)Background: The primary aim was to examine the relationship between lactate threshold (LT) expressed as percentage of maximal oxygen uptake (VO2max) and running velocity at LT (LTV). A secondary aim was to investigate to ... -
Fractional stability of trunk acceleration dynamics of daily-life walking: toward a unified concept of gait stability
(Journal article; Peer reviewed, 2017)Over the last decades, various measures have been introduced to assess stability during walking. All of these measures assume that gait stability may be equated with exponential stability, where dynamic stability is ... -
From juniors to seniors: changes in training characteristics and aerobic power in 17 world-class cross-country skiers
(Journal article; Peer reviewed, 2023)Purpose: To compare training characteristics and aerobic power (VO2max) between the most successful junior and senior seasons of world-class cross-country (XC) skiers and to identify differences between sexes and among ... -
Functional profiling reveals altered metabolic activity in divers’ oral microbiota during commercial heliox saturation diving
(Peer reviewed; Journal article, 2021)Background: The extreme environment in saturation diving affects all life forms, including the bacteria that reside on human skin and mucosa. The oral cavity alone is home to hundreds of different bacteria. In this study, ... -
Hemoglobin and Erythropoietin After Commercial Saturation Diving
(Journal article; Peer reviewed, 2018)Saturation divers are exposed to elevated partial pressure of oxygen (ppO2) in their hyperbaric work environment. Experimental studies indicate that oxygen transport is altered, and we have previously reported a drop in ... -
Hemoglobin during and following a four-week commercial saturation dive to 200 meters
(Journal article; Peer reviewed, 2019)Commercial saturation divers must acclimatize to hyperbaric hyperoxia in their work environment, and subsequently readjust to breathing normal air when their period in saturation is over. In this study, we measured hemoglobin ... -
Hydration Status During Commercial Saturation Diving Measured by Bioimpedance and Urine Specific Gravity
(Peer reviewed; Journal article, 2022)Excessive fluid loss triggered by hyperbaric pressure, water immersion and hot water suits causes saturation divers to be at risk of dehydration. Dehydration is associated with reductions in mental and physical performance, ... -
Introduction to multifractal detrended fluctuation analysis in Matlab
(Journal article; Peer reviewed, 2012)Fractal structures are found in biomedical time series from a wide range of physiological phenomena. The multifractal spectrum identifies the deviations in fractal structure within time periods with large and small ... -
