Competitive Cross-Country Skiers Have Longer Time to Exhaustion Than Recreational Cross-Country Skiers During Intermittent Work Intervals Normalized to Their Maximal Aerobic Power
(Peer reviewed; Journal article, 2023)Purpose: To investigate differences in time to exhaustion (TTE), O2 uptake (˙VO2), and accumulated O2 deficit (Odef2) between competitive and recreational cross-country (XC) skiers during an intermittent-interval protocol ... -
Critical evaluation of oxygen-uptake assessment in swimming
(Journal article; Peer reviewed, 2014-03)Swimming has become an important area of sport science research since the 1970s, with the bioenergetic factors assuming a fundamental performance-influencing role. The purpose of this study was to conduct a critical ... -
Cross-Country Skiers With a Fast-Start Pacing Pattern Increase Time-Trial Performance by Use of a More Even Pacing Strategy
(Peer reviewed; Journal article, 2022)Purpose: To investigate whether skiers with a fast-start pacing pattern increase time-trial performance by use of a more even pacing strategy. Methods: Thirty-four skiers (∼17 y, 16 male) performed an individual 7.5 (3 × 2.5) ... -
Double-Poling Physiology and Kinematics of Elite Cross-Country Skiers: Specialized Long-Distance Versus All-Round Skiers
(Peer reviewed; Journal article, 2019)Purpose: Long-distance cross-country skiers specialize to compete in races >50 km predominantly using double poling (DP). This emphasizes the need for highly developed upper-body endurance capacities and an efficient DP ... -
Effect of traditional and resisted sprint training in highly-trained, female team handball players
(Journal article; Peer reviewed, 2014)Fast acceleration is an important performance factor in handball. In addition to traditional sprint training (TST), resisted sprint training (RST) is a method often used to improve acceleration. However, studies on RST ... -
Effects of active versus passive recovery in sprint cross-country skiing.
(Journal article; Peer reviewed, 2015-07-05)Purpose: To investigate the effects of an active and a passive recovery protocol on physiological responses and performance between 2 heats in sprint cross-country skiing. Methods: Ten elite male skiers (22 ± 3 y, 184 ± 4 ... -
High-intensity events in international women’s team handball matches
(Journal article; Peer reviewed, 2017-01)Purpose: International women’s team handball is a physically demanding sport and is intermittent in nature. The aim of the study was to profile high-intensity events (HIEs) in international women’s team handball matches ... -
Highly Trained Biathletes With a Fast-Start Pacing Pattern Improve Time-Trial Skiing Performance by Pacing More Evenly
(Peer reviewed; Journal article, 2023)Purpose: In sprint biathlon, a J-shaped pacing pattern is commonly used. We investigated whether biathletes with a fast-start pacing pattern increase time-trial skiing and shooting performance by pacing more evenly. Methods: ... -
Improving the value of fitness testing for football
(Journal article; Peer reviewed, 2014-05)One of the challenges for sports scientists working in football is to balance the needs for routine fitness testing with daily fatigue and well-being monitoring to best manage the physical preparation of players. In this ... -
Is Rating of Perceived Exertion a Valuable Tool for Monitoring Exercise Intensity During Steady-State Conditions in Elite Endurance Athletes?
(Peer reviewed; Journal article, 2021)Purpose: Rating of perceived exertion (RPE) is a widely used tool to assess subjective perception of effort during exercise. The authors investigated between-subject variation and effect of exercise mode and sex on Borg ... -
Load-Velocity Profile and Active Drag in Young Female Swimmers: An Age-Group Comparison
(Peer reviewed; Journal article, 2023)Purpose: The present study aimed to establish differences in load–velocity profiling, active drag (AD), and drag coefficient (Cd) between 3 age groups of female swimmers. Methods: Thirty-three swimmers (11, 13, or 16 y ... -
Morning Preconditioning Exercise Does Not Increase Afternoon Performance in Competitive Runners
(Peer reviewed; Journal article, 2021)Purpose: Preconditioning exercise is a widely used strategy believed to enhance performance later the same day. The authors examined the influence of preconditioning exercises 6 hours prior to a time-to-exhaustion (TTE) ... -
