Associations between serum and plasma brain-derived neurotrophic factor and influence of storage time and centrifugation strategy
(Peer reviewed; Journal article, 2019)The aims of the study were to clarify the impact of storage time and centrifugation strategy on brain-derived neurotrophic factor (BDNF) levels in human serum and plasma samples. In addition, we analyzed associations between ... -
Associations of physical activity and sedentary time with body composition in Brazilian young adults
(Peer reviewed; Journal article, 2019)The findings of studies on the association between physical activity and adiposity are not consistent, and most are cross-sectional and used only self-reported measures. The aims of this study were to evaluate: 1) independent ... -
Body roll amplitude and timing in backstroke swimming and their differences from front crawl at the same swimming intensities
(Peer reviewed; Journal article, 2021)The current study investigated body roll amplitude and timing of its peak in backstroke and compared them with front crawl swimming. Nineteen anatomical landmarks were digitised using 80 swimming trial videos (ten ... -
Cardiorespiratory fitness assessment using risk-stratified exercise testing and dose–response relationships with disease outcomes
(Peer reviewed; Journal article, 2021)Cardiorespiratory fitness (CRF) is associated with mortality and cardiovascular disease, but assessing CRF in the population is challenging. Here we develop and validate a novel framework to estimate CRF (as maximal oxygen ... -
Comparability of accelerometer signal aggregation metrics across placements and dominant wrist cut points for the assessment of physical activity in adults
(Peer reviewed; Journal article, 2019)Large epidemiological studies that use accelerometers for physical behavior and sleep assessment difer in the location of the accelerometer attachment and the signal aggregation metric chosen. This study aimed to assess ... -
Comparison of finger flexor resistance training, with and without blood flow restriction, on perceptional and physiological responses in advanced climbers
(Peer reviewed; Journal article, 2023)This study compared perceptional and physiological responses of finger flexor exercise performed with free flow and blood flow restriction (BFR). Thirteen male advanced climbers completed three sessions of finger flexor ... -
DNA methylation across the genome in aged human skeletal muscle tissue and muscle‑derived cells: The role of HOX genes and physical activity
(Peer reviewed; Journal article, 2020)Skeletal muscle tissue demonstrates global hypermethylation with age. However, methylome changes across the time-course of differentiation in aged human muscle derived cells, and larger coverage arrays in aged muscle tissue ... -
The effects of being told you are in the intervention group on training results: A pilot study
(Peer reviewed; Journal article, 2023)Little is known about the placebo effects when comparing training interventions. Consequently, we investigated whether subjects being told they are in the intervention group get better training results compared to subjects ... -
Gender-specific mediators of the association between parental education and adiposity among adolescents: The HEIA study
(Peer reviewed; Journal article, 2019)Identifying the mechanisms behind socioeconomic inequalities in adiposity among youth is vital for efforts aimed at combating these inequalities. The study explored whether a broad range of behavioral and familial factors ... -
Higher lipid turnover and oxidation in cultured human myotubes from athletic versus sedentary young male subjects
(Journal article; Peer reviewed, 2018)In this study we compared fatty acid (FA) metabolism in myotubes established from athletic and sedentary young subjects. Six healthy sedentary (maximal oxygen uptake (VO2max)≤ 46 ml/kg/min) and six healthy athletic ... -
The impact of hypothetical interventions on adiposity in adolescence
(Peer reviewed; Journal article, 2021)In order to develop effective public health initiatives aimed at promoting healthy weight development, identifying the interventions/combination of interventions with the highest beneficial effect on body weight is vital. ... -
Injury prevention in Super-G alpine ski racing through course design
(Peer reviewed; Journal article, 2021)In Super-G alpine ski racing mean speed is nearly as high as in Downhill. Hence, the energy dissipated in typical impact accidents is similar. However, unlike Downhill, on Super-G courses no training runs are performed. ... -
Investigation of individual strategies in the aerial phase in ski jumping
(Peer reviewed; Journal article, 2023)The purpose of this investigation was to examine the performance strategy of three ski jumpers during the steady glide phase and explain how different strategical solutions can lead to jumps of roughly the same length. In ... -
Prenatal and birth predictors of objectively measured physical activity and sedentary time in three population-based birth cohorts in Brazil
(Peer reviewed; Journal article, 2020)Physical inactivity is a global pandemic with no signs of improvement. Prolonged sitting time is an emerging risk factor that exacerbates the health consequences of physical inactivity. Both behaviours are influenced by ... -
Rate of force development relationships to muscle architecture and contractile behavior in the human vastus lateralis
(Peer reviewed; Journal article, 2022)In this study, we tested the hypotheses that (i) rate of force development (RFD) is correlated to muscle architecture and dynamics and that (ii) force–length–velocity properties limit knee extensor RFD. Twenty-one healthy ... -
Reliability of the active drag assessment using an isotonic resisted sprint protocol in human swimming
(Peer reviewed; Journal article, 2022)The purpose of the presents study was to investigate the reliability of the active drag (Da) assessment using the velocity perturbation method (VPM) with different external resisted forces. Eight male and eight female ...
