Talentfull gjennom lek? Forholdet mellom uorganisert trening, selvregulert læring og trenerens talentvurdering blant unge norske fotballspillere
2015
Masteroppgave idrettsvitenskap- Universitetet i Agder, 2015 Denne tverrsnittstudien undersøkte forholdet mellom selvregulert læring, antall timer ustrukturert trening og trenerens talentvurdering hos unge norske fotballspillere. I tillegg ble forholdet mellom selvregulert læring og mengde ustrukturert trening studert. Tidligere forskning innen talentidentifikasjon har vist at mange av de beste akademiene i europeisk fotball ofte foretrekker spillere som tar ansvar for egen læring gjennom selvregulering og trener på egenhånd utenom organiserte treninger. Med tanke på disse funnene forventet vi de samme tendensene på vårt utvalg av 365 mannlige og 167 kvinnelige fotballspillere i alderen 13-2…
Is simple better? A methodical comparison of monitoring training load in well-trained cyclists
2015
Masteroppgave idrettsvitenskap- Universitetet i Agder, 2015 Background: Lack of a “gold-standard” for measuring training load (TL) makes it challenging for coaches and athletes to avoid over- or under-reaching during endurance training. Purpose: To describe physical and perceptual exertional demands of high intensity training (HIT) and explain variance in quantification of TL with use of Banister’s training impulse (BanTRIMP), session rating of perceived exertion (sRPE) and individualized training impulse (iTRIMP). Method: During 12 weeks, 12 well-trained male cyclists (VO2peak 60 ± 3 ml · kg-1 · min-1) completed 879 individual endurance training sessions including HIT-sessions; 4 x 16 min,…
Prestasjonsutvikling på skøyter : en casestudie på tre juniorverdensmestere på skøyter
2013
Masteroppgave i idrettsvitenskap - Universitetet i Agder 2013 Background: The lack of studies regarding training characteristics among speed skaters. Aim: The aim of the study was to quantify in detail the physiological development, training distribution, and success factors of three international successful junior athletes in order to better understand best practice development for speed skaters. Subjects: Three male skaters with a total of 25 medals at the Junior World Championships Methods: Training and test data were retrospective and collected from documented test and performance results, plus training diaries and interviews with coaches. Workouts were digitized and summarized using st…
The relationship between physical activity and physical self-esteem in adolescents: the role of physical fitness indices.
2013
The aim of this study was to investigate if physical fitness (strength/power, endur ance, flexibility and coordination) mediates the cross-sectional relationship between physical activity and physical self-perception (athletic competence and physical appearance) in a sample of 15-year old adolescents. We wanted to investigate the relative strength of each indirect effect. The present data are taken from two waves of a larger data collection for the project “Youth in Balance”, and was collected in the autumn of 2005 (N = 1207) and 2008 (N = 632). A total of 1839 students (889 girls and 950 boys) from 12 schools in Kristiansand took part. A bias-corrected bootstrapping technique was used to e…
Traditional versus functional strength training: effects on muscle strength and power in the elderly.
2012
Published versiom of an article in the journal:Journal of Aging and Physical Activity. Also available from Human Kinetics: http://http://journals.humankinetics.com/japa-back-issues/japa-volume-21-issue-1-january/traditional-versus-functional-strength-training-effects-on-muscle-strength-and-power-in-the-elderly The aim was to determine whether strength training with machines vs. functional strength training at 80% of one-repetition maximum improves muscle strength and power among the elderly. Sixty-three subjects (69.9 +/- 4.1 yr) were randomized to a high-power strength group (HPSG), a functional strength group (FSG), or a nonrandomized control group (CG). Data were collected using a force …
Parental education associations with children's body composition: Mediation effects of energy balance-related behaviors within the ENERGY-project
2013
AbstractBackgroundIt is well known that the prevalence of overweight and obesity is considerably higher among youth from lower socio-economic families, but there is little information about the role of some energy balance-related behaviors in the association between socio-economic status and childhood overweight and obesity. The objective of this paper was to assess the possible mediation role of energy balance-related behaviors in the association between parental education and children’s body composition.MethodsData were obtained from the cross sectional study of the “EuropeaN Energy balance Research to prevent excessive weight Gain among Youth” (ENERGY) project. 2121 boys and 2516 girls a…
The role and development of sprinting speed in soccer.
2013
Author's version of an article in the journal: International Journal of Sports Physiology and Performance. Also available from the publisher at: http://dx.doi.org/10.1123/IJSPP.2013-0121 The overall objective of this review was to investigate the role and development of sprinting speed in soccer. Time–motion analyses show that short sprints occur frequently during soccer games. Straight sprinting is the most frequent action before goals, both for the scoring and assisting player. Straight-line sprinting velocity (both acceleration and maximal sprinting speed), certain agility skills, and repeated-sprint ability are shown to distinguish groups from different performance levels. Professional …
Reasons for officiating soccer : the role of passion-based motivations among Norwegian elite and non-elite referees
2015
Les raisons de l’arbitrage en football : Le role des motivations basees sur la passion parmi les arbitres elite et non-elite norvegiensCette etude examine les raisons de l’investissement des arbitres de football elite et non-elite norvegiens. Quatre-vingt-trois arbitres elite et 44 non-elite ont complete un questionnaire en ligne (SurveyXact) interrogeant leurs trois principales raisons d’exercer la fonction d’arbitre de football. Les donnees ont ete obtenues par epoche, intuition et description de leurs differentes raisons. Trois principales categories descriptives emergent (pourcentage elite/non-elite) : les motivations liees a la passion (57/25 %), les motivations sociales (25/25 %) et l…
Development of basic psychological need satisfaction in physical education - Effects of a two-year PE programme
2019
Research shows that sports-active students experience more basic need satisfaction (autonomy, competence, relatedness) in physical education (PE) than their non-sports-active peers, and thus, reap most of the benefits of PE. This study aimed to investigate the role of a two-year PE programme, referred to as Interest-based PE, in contributing to students’ basic need satisfaction in PE, and in particular, to assess potential basic needs-benefits among students who were not involved in leisure-time sport. Among 693 students, 348 were offered a choice of two different PE approaches (“explorative” vs. “sports” approach) for the next two years, while the remaining students continued to receive tr…
Perceptions of leadership behavior and the relationship to athletes among Scandinavian coaches
2014
Published version of an article in the journal: Scandinavian Sport Studies Forum. Also available from the publisher at: http://sportstudies.org/2014/11/25/perceptions-of-leadership-behavior-and-the-relationship-to-athletes-among-scandinavian-coaches/ -Open Access The purpose of this study was to investigate the relationship between the perceptions of leadership behavior and coach–athlete relationship in Scandinavian coaches. A secondary purpose was to investigate if differences in national sport education, level of coaching and coaching experiences in individual or team sport have an influence on leadership behavior and coach–athlete relationships. One hundred and forty nine coaches at inte…
