Effects of between-set interventions on neuromuscular function during isokinetic maximal concentric contractions of the knee extensors
2011
The presents study investigated the effects of between-set interventions on neuromuscular function of the knee extensors during six sets of 10 isokinetic (120°·s(-1)) maximal concentric contractions separated by three minutes. Twelve healthy men (age: 23.9 ± 2.4 yrs) were tested for four different between-set recovery conditions applied during two minutes: passive recovery, active recovery (cycling), electromyostimulation and stretching, in a randomized, crossover design. Before, during and at the end of the isokinetic session, torque and thigh muscles electromyographic activity were measured during maximal voluntary contractions and electrically-evoked doublets. Activation level was calcul…
The effects of vibration during maximal graded cycling exercise: A pilot study
2012
Whole Body Vibration training is studied and used in different areas, related to sport performance and rehabilitation. However, few studies have investigated the effects of Vibration (Vib) exposure on aerobic performance through the application of this concept to cycling exercise. A specifically designed vibrating cycloergometer, the powerBIKETM, was used to compare the effects of Vib cycling exercise and normal cycling on different physiological parameters during maximal graded exercise test. Twelve recreationally active male adults (25 ± 4.8 yrs; 181.33 ± 5.47 cm; 80.66 ± 11.91 kg) performed two maximal incremental cycling tests with and without Vib in a blockrandomized order. The protoco…
Prediction of enjoyment in school physical education
2012
The specific aim of this study was to examine whether motivational climate, perceived physical competence, and exercise motivation predict enjoyment in school physical education within the same sample of adolescents across three years of secondary school. A sample of 639 students (girls = 296, boys = 343) aged between 13- to 15-years at the commencement of the study completed the Intrinsic Motivation Climate in Physical Education Questionnaire, Physical Self-Perception Profile, Physical Education Motivation Scale, and Physical Education Enjoyment Scale. Results derived from path analyses indicated that task-involving motivational climate predicted enjoyment in physical education via perceiv…
Self-reported versus diagnosed stress fractures in Norwegian female elite athletes
2009
The aim of this study was to determine the prevalence of self- reported versus diagnosed stress fractures in female elite athletes and non-athletic controls. A random sample of Norwegian elite athletes from the national teams, aged 13-39 years (n = 186) and a random sample of non-athletic controls (n = 145) in the same age group participated in the study. The athletes represented a junior- or senior team, or a recruiting squad for one of these teams, in one of 46 different sports/events. A higher percentage of athletes self-reported stress fractures (14.0%) compared to those diagnosed with stress fractures (8.1%) (p0.001). Six controls self- reported stress fractures, but none of them were …
Forutsetninger for vellykket sosial innovasjon i sykehjem: ledernes perspektiv – en kvalitativ intervjustudie
2019
Preconditions for successful social innovation in nursing homes: Managers' perspectives - a qualitative interview studyIn this article, we investigate preconditions for social innovation in institution-based elderly care in Norway and Denmark. The article draws on two semi-structured interviews and one focus-group interview. The interviewees are managers in elderly-care facilities that are known to be proficient with regards to innovation. The analysis point to three principles managers describe as being pertinent to successful social innovation. Firstly, an overall theme across the interviews was that the managers underscored the importance of eagerness and willingness to change as a prere…

The manager as innovator and equilibrist: a qualitative study of the experiences of Norwegian managers in health and welfare service taking part in research partnership with higher educationManagers in health and welfare services have overall responsibility to develop the services according to official regulations and the needs of society. They are expected to provide high quality, research based services. Higher education is expected to transform education and research that improve the services, and to develop research collaborating with the practical field. This study investigates experiences of managers in health and welfare services taking part in research collaboration with higher educ…
Factores de elección de universidad pública en la Comunidad Valenciana
2015
La tesis aborda dos grandes bloques de objetivos: el análisis de los factores de elección de universidad pública en la Comunidad Valenciana y la modelización de estos procesos de elección. Estos bloques de objetivos se dividen, a su vez, en áreas de investigación: por una parte el análisis de la motivación subyacente para emprender estudios universitarios, el análisis de los factores de elección de universidad y de titulación, las fuentes de información empleadas por las y los estudiantes y la influencia de terceras personas en este proceso, así como los motivos por los que el estudiante finalmente elige la universidad y la titulación en que fue admitido; por otra parte se persigue la model…
Effect of Stacking Sequence and Sodium Bicarbonate Treatment on Quasi-Static and Dynamic Mechanical Properties of Flax/Jute Epoxy-Based Composites
2019
The present paper deals with the investigation of quasi-static and dynamic mechanical response of epoxy-based composites reinforced with flax and/or jute plain weave fabrics. In order to evaluate the influence of the stacking sequence, two monolithic laminates reinforced with flax or jute fibers and two hybrid flax/jute laminates were manufactured through the vacuum infusion technique. Furthermore, an eco-friendly and cost-effective surface treatment based on fiber soaking in a sodium bicarbonate solution was employed to improve the fiber-matrix adhesion. The mechanical characterization (by means of quasi-static flexural, dynamic mechanical thermal analysis and Charpy impact tests) allowed …
The historical development of the Mongolian media landscape : media ecology approach to the development of the Mongolian media from the 1200s to the …
2010
This media ecology thesis assesses the cultural impacts of communication technologies in Mongolia. Acknowledging the interconnectedness of media, its content, and human beings, it shows how changes in Mongolia's media have taken it through phases of orality, craft literacy, literacy, and into secondary orality. The research shows how Mongolia's media has developed over the centuries, how the social and media transformation in the USSR affected the development of Mongolia's media, and finally, to what degree and in what ways the aspects of oral and literate history, societal history and the media landscape relate to the popularity of participatory community radio in Ulaanbaatar. The backgrou…
Relative age and perceptions of soccer specific skills among elite youth players in Norway
2019
One common feature among the selected players in talent development programs are the well-known relative age effect (RAE), characterized by a skewed birth distribution among selected players with an over-representation of players born early in the selection year. The aim of the present study was to examine potential differences in soccer-specific skills between players selected for national talent program born in the first half of the year compared to the players born in the second half of the year. A total of 753 elite male U 14 (N = 363) and U 13 players (N = 390) from 16 of 18 soccer regions in Norway participated. The results showed players born early in the selection year considered th…
