Perceived impact of the menstrual cycle and hormonal contraceptives on physical exercise and performance in 1,086 athletes from 57 sports
(Peer reviewed; Journal article, 2022)Female athletes train and compete under the potential influence of hormonal fluctuations during the menstrual cycle or during use of various hormonal contraceptives. Dysmenorrhea and premenstrual symptoms are common in the ... -
Performance-Related Physiological and Haematological Changes During Pregnancy and Postpartum in a Well-Trained Cyclist Performing Endurance Training
(Peer reviewed; Journal article, 2022)Purpose: To describe the performance-related physiological and haematological changes in a well-trained cyclist (peak oxygen uptake, VO2peak: 54.9 ml min−1·kg−1) performing endurance training during pregnancy and ... -
Physiological and Biomechanical Determinants of Sprint Ability Following Variable Intensity Exercise When Roller Ski Skating
(Peer reviewed; Journal article, 2021)The most common race format in cross-country (XC) skiing is the mass-start event, which is under-explored in the scientific literature. To explore factors important for XC skiing mass-starts, the main purpose of this study ... -
Physiological and Biomechanical Responses to Cross-Country Skiing in Varying Terrain: Low- vs. High-Intensity
(Peer reviewed; Journal article, 2021)The purposes of our study were to investigate the physiological and biomechanical responses to low-intensity (LI) and high-intensity (HI) roller ski skating on varying terrain and compare these responses between training ... -
Physiological Response to Cycling With Variable Versus Constant Power Output
(Peer reviewed; Journal article, 2020)Introduction: Variable power output (VP) is one of the main characteristics of a road cycling mass-start. Tolerating VP during outdoor road cycling highly influences performance. There is a lack of continuous and comprehensive ... -
Power production and biochemical markers of metabolic stress and muscle damage following a single bout of short-sprint and heavy strength exercise in well-trained cyclists
(Journal article; Peer reviewed, 2018)Purpose: Although strength and sprint training are widely used methods in competitive cycling, no previous studies have compared the acute responses and recovery rates following such sessions among highly trained cyclists. ... -
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 ... -
A Reappraisal of Ventilatory Thresholds in Wheelchair Athletes With a Spinal Cord Injury: Do They Really Exist?
(Journal article; Peer reviewed, 2021)The ventilatory threshold (VT) separates low- from moderate-intensity exercise, the respiratory compensation point (RCP) moderate- from high-intensity exercise. Both concepts assume breakpoints in respiratory data. However, ... -
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 ... -
The return from underperformance to sustainable world-class level: A case study of a male cross-country skier
(Journal article; Peer reviewed, 2023) -
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, ... -
Strategies to Enhance Logic Modeling-Based Cell Line-Specific Drug Synergy Prediction
(Journal article; Peer reviewed, 2020)Discrete dynamical modeling shows promise in prioritizing drug combinations for screening efforts by reducing the experimental workload inherent to the vast numbers of possible drug combinations. We have investigated ... -
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 ... -
Test–Retest Reliability of Physiological Variables During Submaximal Seated Upper-Body Poling in Able-Bodied Participants
(Journal article; Peer reviewed, 2021)Purpose: To investigate the test–retest reliability of physiological variables across four different test days and four different submaximal exercise intensities during seated upper-body poling (UBP). Methods: Thirteen ... -
The long-term development of training, technical, and physiological characteristics of an Olympic Champion in Nordic Combined
(Journal article; Peer reviewed, 2018)Nordic combined requires high technical skills and vertical impulse for the ski-jumping event and aerobic endurance, ski efficiency and finish-sprint abilities to succeed in the subsequent cross-country race. The main aim ... -
