(Journal article; Peer reviewed, 2019)Rationale: The main purposes of this study were to compare mitochondrial respiration in M. triceps brachii and M. vastus lateralis between elite cross-country (XC) skiers and physically active controls (CON), and to explore ... -
Comparison of Peak Oxygen Uptake and Test-Retest Reliability of Physiological Parameters between Closed-End and Incremental Upper-Body Poling Tests
(Journal article; Peer reviewed, 2017)Objective: To compare peak oxygen uptake (VO2peak) and the test-retest reliability of physiological parameters between a 1-min and a 3-min closed-end and an incremental open-end upper-body poling test. Methods: On two ... -
Comparison of peak oxygen uptake between upper-body exercise modes: A systematic literature review and meta-analysis
(Peer reviewed; Journal article, 2020)Purpose: To compare peak oxygen uptake (VO2peak) between the asynchronous arm crank ergometry (ACE), and synchronous wheelchair ergometry (WERG), wheelchair treadmill (WTR), and upper-body poling (UBP) mode. Methods: ... -
Comparison of Short-Sprint and Heavy Strength Training on Cycling Performance
(Journal article; Peer reviewed, 2019)Purpose: To compare the effects of short-sprint training (SST) and heavy-strength training (HST) following a 4-week strength-training period on sprint and endurance capacities in well-trained cyclists. Methods: Twenty-eight ... -
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 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 ... -
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 ... -
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 ... -
