Cardiorespiratory Fitness, Physical Activity, and Insulin Resistance in Children
(Peer reviewed; Journal article, 2020)Purpose: Few studies have investigated the independent and joint associations of cardiorespiratory fitness (CRF) and body fat percentage (BF%) with insulin resistance in children. We investigated the independent and combined ... -
Classification of cross-country ski skating sub-technique can be automated using carrier-phase differential GNSS measurements of the head's position
(Peer reviewed; Journal article, 2021)Position–time tracking of athletes during a race can provide useful information about tactics and performance. However, carrier-phase differential global navigation satellite system (dGNSS)-based tracking, which is accurate ... -
Crossing the golden training divide: The science and practice of training world-class 800- and 1500-m runners
(Peer reviewed; Journal article, 2021)Despite an increasing amount of research devoted to middle-distance training (herein the 800 and 1500 m events), information regarding the training methodologies of world-class runners is limited. Therefore, the objective ... -
Determinants of the maximal functional reserve during repeated supramaximal exercise by humans: The roles of Nrf2/Keap1, antioxidant proteins, muscle phenotype and oxygenation
(Peer reviewed; Journal article, 2023)When high-intensity exercise is performed until exhaustion a “functional reserve” (FR) or capacity to produce power at the same level or higher than reached at exhaustion exists at task failure, which could be related to ... -
Do athletes have more of a cognitive profile with ADHD criteria than non-athletes?
(Peer reviewed; Journal article, 2021)The current study investigates the possibility that athletes have more parallel ADHD symptoms than non-athletes. High-level youth sport athletes were compared with non-athletes in leisure time (i.e., sport) and in the ... -
Dual career support among world-class athletes in Sweden: Performance, education, and employment
(Peer reviewed; Journal article, 2023)In order to help talented athletes to combine sport and education, different forms of Dual Career Support (DCS) have been developed in many countries. The effectiveness of these support systems have been debated. Most ... -
Effectiveness of individualized training based on force: Velocity profiling on physical function in older men
(Peer reviewed; Journal article, 2022)The study aimed to investigate the effectiveness of an individualized power training program based on force–velocity (FV) profiling on physical function, muscle morphology, and neuromuscular adaptations in older men. ... -
Effects of high and low training volume with the Nordic hamstring exercise on hamstring strength, jump height, and sprint performance in female football players: A randomised trial
(Peer reviewed; Journal article, 2022)The evidence-based hamstring strengthening programme for prevention of hamstring injuries is not adopted by football teams because of its high training volume. This study on female football players investigated if high-volume ... -
Exhaustive exercise and post-exercise protein plus carbohydrate supplementation affect plasma and urine concentrations of sulfur amino acids, the ratio of methionine to homocysteine and glutathione in elite male cyclists
(Peer reviewed; Journal article, 2020)Plasma and tissue sulfur amino acid (SAA) availability are crucial for intracellular methylation reactions and cellular antioxidant defense, which are important processes during exercise and in recovery. In this randomized, ... -
External load variables affect recovery markers up to 72 h after semiprofessional football matches
(Peer reviewed; Journal article, 2019)Background: Player tracking devices are commonly used to monitor external load from training and matches in team sports. Yet, how the derived external load variables relate to fatigue and recovery post-training or post-match ... -
Fast regulation of the NF-κB signalling pathway in human skeletal muscle revealed by high-intensity exercise and ischaemia at exhaustion: Role of oxygenation and metabolite accumulation
(Peer reviewed; Journal article, 2022)The NF-κB signalling pathway plays a critical role in inflammation, immunity, cell proliferation, apoptosis, and muscle metabolism. NF-κB is activated by extracellular signals and intracellular changes in Ca2+, Pi, H+, ... -
