En kvinnelig toppidrettsutøvers refleksjoner over egen karriere : håndtering av med- og motgang i idrettskarrieren belyst gjennom forståelse av hvord…

Masteroppgave i idrettsvitenskap - Universitetet i Agder 2016 Title A Top Female Athlete's Reflection on her Career - Dealing with adversity in a sports career illustrated through the understanding of how motivation and coping skills can help to overcome career obstacles. Project Background Many athletes, especially women, feel they lose the motivation for playing sports early on in their careers. There is a need for more knowledge regarding coping capabilities in the face of decreasing motivation to continue a sports career. Purpose and problem There is a need to understand how women who have experienced hardship but still chose to continue with their sport, think about coping mechanisms w…
”En ny hverdag”. Mødres opplevelse av hverdagen med et prematurt barn, og støtten ved en ressurshelsestasjon
2015
The study explores mothers’ of premature infants experience of how health centers especially adapted for families with premature infants can help them to cope with everyday life after discharge from a neonatal intensive care unit. Background: Premature children are at higher risk for physical and mental health problems, which makes parenting demanding. The transition between hospital and home is a challenging period where parents may need extra support to cope with everyday life. Method: Nine mothers of premature infants receiving follow-up care at a health center especially adapted for families with premature infants were interviewed. Data were analyzed by Kvale and Brinkmann’s guidelines …

Masteroppgave psykisk helsearbeid ME504 - Universitetet i Agder 2018 Throughout our working carrier we have met youth who had dropped out from upper secondary school with that consequence that they stand without work or education. We wish to approach the phenomenon dropouts from the perspective of the youth, here boys, to try to find out more about how they think of their own possibilities. This study is part of a research project at the University of Agder and represents a contribution to the research group “Ung i Sør”. The purpose of this study is to increase understanding around how boys explain the causes behind their choice to dropout and what they express can contribute to returning t…

Focusing on Increasing Velocity during Heavy Resistance Knee Flexion Exercise Boosts Hamstring Muscle Activity in Chronic Stroke Patients
2016
Background. Muscle strength is markedly reduced in stroke patients, which has negative implications for functional capacity and work ability. Different types of feedback during strength training exercises may alter neuromuscular activity and functional gains.Objective. To compare levels of muscle activity during conditions of blindfolding and intended high contraction speed with a normal condition of high-intensity knee flexions.Methods. Eighteen patients performed unilateral machine knee flexions with a 10-repetition maximum load. Surface electromyography (EMG) was recorded from the quadrics and hamstring muscles and normalized to maximal EMG (nEMG) of the nonparetic limb.Results. For the …
The Principles of Quantum Theory
2013
This chapter develops the formal framework of quantum mechanics: the mathematical tools, generalization and abstraction of the notion of state, representation theory, and a first version of the postulates on which quantum theory rests.
Exercise for fitness does not decrease the muscular inactivity time during normal daily life
2012
The time spent in sedentary behaviors has been shown to be independent of exercise in epidemiological studies. We examined within an individual whether exercise alters the time of muscular inactivity within his/her normal daily life. Quadriceps and hamstring muscle electromyographic activities and heart rate were measured during 1 to 6 days of normal daily living of ordinary people. Of 84 volunteers measured, 27 (15 men, 12 women, 40.7 years ± 16.5 years) fulfilled the criteria of having at least 1 day with and 1 day without exercise for fitness (total of 87 days analyzed, 13.0 h ± 2.5 h/day). Reported exercises varied from Nordic walking to strength training and ball games lasting 30 min-1…
Validity of an inertial system for measuring velocity, force, and power during hamstring exercises performed on a flywheel resistance training device
2020
Background Inertial hamstring exercises promote functional changes leading to lower rates of hamstring injuries. However, variable training measurement systems have not been specifically validated for hamstring exercises. Accordingly, this study aimed to evaluate the validity of the Inertial Measurement System (IMS) to measure the velocity, force, and power during the performance of different hamstring exercises on a flywheel resistance training device. Methods Fifteen males (average age: 22.4 ± 2.5 years; body mass: 77.3 ± 9.8 kg; height: 179.5 ± 7.4 cm; weekly physical activity: 434.0 ± 169.2 min; years of strength training: 4.3 ± 2.2 years) performed the bilateral stiff-leg deadlift (SD…
Comparison of conventional hamstring/quadriceps ratio between genders in level-matched soccer players
2017
Abstract Objectives The main goal of our study is to compare the hamstring/quadriceps ( H / Q ) ratio at different knee angles between level-matched male and female soccer players and to determine whether differences in the H / Q ratio exist between the dominant and the non-dominant leg. Methods A cross-sectional study design was used to compare an isometric H / Q ratio and functional isokinetic ratio (between hamstring in eccentric contraction and quadriceps in concentric contraction) between males ( n = 14) and females ( n = 14). These ratios were studied at two different speeds of movement (60° s −1 and 180° s −1 ) and in five different positions (40°, 50°, 60°, 70° and 80° degrees of …
Do Running and Strength Exercises Reduce Daily Muscle Inactivity Time?
2016
Understanding how a specific exercise changes daily activity patterns is important when designing physical activity interventions. We examined the effects of strength and interval running exercise sessions on daily activity patterns using recordings of quadriceps and hamstring muscle electromyographic (EMG) activity and inactivity. Five male and five female subjects taking part in a 10-week training programme containing both strength and interval running training sessions were measured for daily muscle EMG activities during three days: on a strength day, an interval running day, and a day without exercise. EMG was measured using textile electrodes embedded into sport shorts that were worn 9…
