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, ... -
Iron Deficiency Impacts Diastolic Function, Aerobic Exercise Capacity, and Patient Phenotyping in Heart Failure With Preserved Ejection Fraction: A Subanalysis of the OptimEx-Clin Study
(Peer reviewed; Journal article, 2022)Aims: Iron deficiency (ID) is linked to reduced aerobic exercise capacity and poor prognosis in patients with heart failure (HF) with reduced ejection fraction (HFrEF); however, data for HF with preserved ejection fraction ... -
No change – no gain; The effect of age, sex, selected genes and training on physiological and performance adaptations in cross-country skiing
(Peer reviewed; Journal article, 2020)The aim was to investigate the effect of training, sex, age and selected genes on physiological and performance variables and adaptations before, and during 6 months of training in well-trained cross-country skiers. ... -
Prediction of guidewire-induced aortic deformations during EVAR: a finite element and in vitro study
(Peer reviewed; Journal article, 2023)Introduction and aims: During an Endovascular Aneurysm Repair (EVAR) procedure a stiff guidewire is inserted from the iliac arteries. This induces significant deformations on the vasculature, thus, affecting the pre-operative ... -
Predictive Physiological Modeling of Percutaneous Coronary Intervention - Is Virtual Treatment Planning the Future?
(Journal article; Peer reviewed, 2018)Computational modeling has been used routinely in the pre-clinical development of medical devices such as coronary artery stents. The ability to simulate and predict physiological and structural parameters such as flow ... -
Relationships Between Maximal Aerobic Speed, Lactate Threshold, and Double Poling Velocity at Lactate Threshold in Cross-Country Skiers
(Peer reviewed; Journal article, 2022)Purpose: To investigate the relationships between maximal aerobic speed (MAS), lactate threshold in per cent of peak oxygen uptake (LT) and velocity at LT (LTv) in cross-country skiers. Secondly, we aimed to explore the ... -
Responses to Maximal Strength Training in Different Age and Gender Groups
(Peer reviewed; Journal article, 2021)Purpose: The present study aimed to investigate the potential impact of age, gender, baseline strength, and selected candidate polymorphisms on maximal strength training (MST) adaptations. Methods: A total of 49 subjects ... -
Shifts in the oral microbiota during a four-week commercial saturation dive to 200 meters
(Peer reviewed; Journal article, 2021)During commercial saturation diving, divers live and work under hyperbaric and hyperoxic conditions. The myriads of bacteria that live in and on the human body must adjust to the resultant hyperbaric stress. In this study, ... -
Stronger Is Better: The Impact of Upper Body Strength in Double Poling Performance
(Journal article; Peer reviewed, 2019)The purpose of the present study was to compare time results from a roller-skiing double poling (DP) time trial with different physiological variables, muscular strength variables, and DP characteristics in both male and ... -
Using Salivary Biomarkers for Stress Assessment in Offshore Saturation Diving: a Pilot Study
(Peer reviewed; Journal article, 2021)Health monitoring during offshore saturation diving is complicated due to restricted access to the divers, the desire to keep invasive procedures to a minimum, and limited opportunity for laboratory work onboard dive support ... -
Wrist ballistocardiography and invasively recorded blood pressure in healthy volunteers during reclining bike exercise
(Peer reviewed; Journal article, 2023)Objective: Ballistocardiogram (BCG) features are of interest in wearable cardiovascular monitoring of cardiac performance. We assess feasibility of wrist acceleration BCG during exercise for estimating pulse transit time ...
