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 ... -
Fitness determinants of repeated-sprint ability in highly trained youth football players
(Journal article; Peer reviewed, 2011)Variations in rates of growth and development in young football players can influence relationships among various fitness qualities. Purpose: To investigate the relationships between repeated-sprint ability and other ... -
Force-velocity profiling in athletes: Reliability and agreement across methods
(Peer reviewed; Journal article, 2021)The aim of the study was to examine the test-retest reliability and agreement across methods for assessing individual force-velocity (FV) profiles of the lower limbs in athletes. Using a multicenter approach, 27 male ... -
Re-examination of accelerometer data processing and calibration for the assessment of physical activity intensity
(Peer reviewed; Journal article, 2019)This review re‐examines the use of accelerometer and oxygen uptake data for the assessment of activity intensity. Accelerometers capture mechanical work, while oxygen uptake captures the energy cost of this work. Frequency ... -
Separating movement and gravity components in an acceleration signal and implications for the assessment of human daily physical activity
(Journal article; Peer reviewed, 2013-04-23)Human body acceleration is often used as an indicator of daily physical activity in epidemiological research. Raw acceleration signals contain three basic components: movement, gravity, and noise. Separation of these becomes ... -
Sprint conditioning of junior soccer players: effects of training intensity and technique supervision
(Journal article; Peer reviewed, 2015-03-23)The aims of the present study were to compare the effects of 1) training at 90 and 100% sprint velocity and 2) supervised versus unsupervised sprint training on soccer-specific physical performance in junior soccer players. ... -
The effect of individualised sprint training in elite female team sport athletes: A pilot study
(Journal article; Peer reviewed, 2018)This study aimed to evaluate whether an individualised sprint-training program was more effective in improving sprint performance in elite team-sport players compared to a generalised sprint-training program. Seventeen ... -
Training at maximal power in resisted sprinting: Optimal load determination methodology and pilot results in team sport athletes
(Journal article; Peer reviewed, 2018)Aims: In the current study we investigated the effects of resisted sprint training on sprinting performance and underlying mechanical parameters (force-velocity-power profile) based on two different training protocols: (i) ... -
Unit-specific calibration of Actigraph accelerometers in a mechanical setup - Is it worth the effort? The effect on random output variation caused by technical inter-instrument variability in the laboratory and in the field
(Peer reviewed; Journal article, 2008-04-11)Conclusion: The application of unit-specific calibration factors to data collected during free living conditions had no apparent effect on inter-instrument variability. In all probability, the effect of technical calibration ... -
Validity of velocity measurements of a motorized resistance device during change of direction
(Peer reviewed; Journal article, 2022)The aim of this study was to determine validity of velocity measurements of a motorized resistance device (MRD) during change of direction (CoD). Eight male (age: 22.1 ± 4.2 yrs; weight: 83.3 ± 17.1 kg; height: 181.6 ± 12.6 cm) ...
