IntroductionSuccessful training is a key for athletes to make progress in their development. Training must not just involve overload, but also must prevent the combination of excessive overload plus inadequate recovery. Athletes can experience short-term performance decrement without severe psychological or lasting other negative symptoms. Too much hard exercise or too little sleep can cause overtraining, a condition in which the subject can prevent to be away from the sport for several weeks or months. Previous studies have detected that it is important to avoid overtraining.

Syftet med studien var att undersöka öppen förskola som arena för ett hälsofrämjande arbete. Fokus var på de möjligheter och begränsningar som personalen upplevde i sitt arbete utifrån det hälsoprogram som tillämpades av dem. Studien var ett uppdrag från Salutsatsningen vid Västerbottens läns landsting. Metoden var en kvalitativ ansats och fem intervjuer genomfördes med personal inom öppen förskola i Västerbottens län. Intervjuerna utgick från de kriterier som fungerade som riktlinjer för arbetet.

A number of chemical agents, and their degradation products, have been recognized as having estrogenic activity on animals. On fish they interfere with endogenous estrogen and in many cases mimic its activity, thus increase estrogenic reponse, with elevated levels of vitellogenin. Hence they are called Endocrine Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of exposure to estrogenic pollutants. Wastewater from sewage treatment works contains chemicals known as EDCs, and there are evidence of roach (Rutilus rutilus) living in recipients of such wastewater having traits of both gender, i.e. oocytes in male gonads (intersex) on histological examination. This study was done on roach living in Lake Funbosjön Uppland, Sweden.

Objective: The out-of-hospital cardiac-arrest incidence in Sweden averages about 10 000 a year. Whether the victim will survive or not is dependent upon rapid actions according to the chain of survival ? early alarm, early CPR, early defibrillation and early medical treatment. While waiting for the ambulance the victim is completely dependent on immediate help from any bystander, because early CPR improves survival rates by two-three folds. Unfortunately not all bystanders start CPR because of different reasons.

Syftet med denna studie var att undersöka huruvida fysisk aktivitet kan påverka en individs frukostval. Vidare undersöktes på vilket sätt frukostvalet i så fall hade påverkats samt om denna förändring var beroende av ålder och kön. Studien var av empirisk, deskriptiv design. Semistrukturerade intervjuer genomfördes med totalt 98 deltagare, 50 kvinnor och 48 män (16-75 år). Enligt resultatet var den kombinerade träningsformen (konditionsträning och styrketräning) den dominerande bland båda könen.

Background: Testosterone is the most important androgenic hormone in the male. Aging is closely associated with reduction of serum testosterone which can lead to reduced muscle mass, muscle strength, bone density, and depression. These symptoms may be counteracted by administration of testosterone. Objective: The purpose of this study was to examine the effects of hormone replacement in men with age-related testosterone deficiency. Method: We performed a systematic review using Randomised Controlled Trials (RCT).

?Facebook has become as natural as having a phone? The use of social media in three libraries in the Umeå region ? an evaluationSocial media has come to be an integral part of people?s everyday life, as well as the business world in terms of communication and marketing. More and more libraries also embark in the use of social media, and the purpose of this study is to evaluate the use of social media in three libraries in the Umeå region. The libraries all use Facebook as their current, primary social media. Thus this study focuses partly on the analysis of the content on each library?s Facebook page, and partly on the experiences of the responsible librarians. The evaluation is based on a mix of existing tools in evaluating social media that are relevant in a library context.

The purpose of this survey was to map out the health pf some of the 11 and 12 years old children in the city of Umeå, as well as to find out what factors intend to influense the children´s health. A questionnaire was distributed in four 6th grade classes whitin the municipality of Umeå. Two of the schools were located in the city while two were located in near villages. This selection was decided in order to map out diffrences in health related to the children´s home environment. 80 pupils took part of this study.

I och med den nya läroplanen för det obligatoriska skolväsendet, Lpo 94, breddades idrottsämnet och ämnet bytte namn från idrott till idrott och hälsa. Då hälsa är ett komplext och svårdefinierat begrepp var syftet med studien att undersöka tolkningsutrymmet vad gäller hälsa i kursplanen för idrott och hälsa. Studien inkluderade två olika undersökningar varav den ena avsåg en textanalys av samtliga läroplaner för grundskolan med inkluderande kursplaner för idrottsämnet. Detta för att belysa hur hälsosynen och tolkningsutrymmet har utvecklats över tid. Textanalysen kompletterades sedan med intervjuer av fyra behöriga idrottslärare för grundskolan i en kommun för att få inblick i hur yrkesverksamma tolkar hälsa utifrån kursplanen.

Automatic milking systems (AMS) provide the opportunity for less manual labour and an increased milking frequency. But in order to reach an optimal milking frequency a well-functioning cow traffic is crucial. There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. Therefore the aim of this study was to determine the effect of different light intensities during the night on number of selection gate passages (GP), milking frequency and milk yield. The study was conducted as a Latin square were three light intensities were applied: LOW (11 ± 3 lux), INT (33 ± 1 lux) and HIGH (74 ± 6 lux), in three different herds.

The purpose with the examination is to examine a preschool head and three teachers experiences and opinions of whether the tablet can be used to support childrens linguistic development and social interactions in preschool. To answer the purpose we will use these questions of issue:What is the purpose with tablets and how are they used in preschool activity?What pros and cons do the teachers see with tablets?How do the teachers resonate about the use of tablets to develop childrens language skill and social interactions?What type of social interaction occurs when children use the tablet?We have used interviews and observations as our methods. We interviewed three teachers and one preschool head in the capital city of Sweden. They all have a positive attitude towards the use of tablets in preschool.

Outdoor housing of horses? best fulfils the horses? need for physical activity and it is an alternative to the more cost and energy demanding indoor housing in stables. Furthermore, if outdoor housed horses have access to shelter they can generally cope well with adverse weather conditions such as high or low ambient temperature, heavy rain or strong winds. In this study, the daytime shelter-seeking behaviour of three groups of horses housed outdoors was studied during the summer. The aim was to evaluate whether shelter use is related to weather variables (e.g., ambient temperature and wind speed) and insect harassment. The shelter-seeking behaviour was studied for three different groups of horses: Group 1) eight individually housed horses in paddocks that had access to three different shelter types (C: closed on three sides with roof, R: open on three sides with roof, W: closed on three sides without roof), Group 2) 25 group housed mares with foals on pasture with access to shelters C, and Group 3) ten mares without foals on pasture without access to shelter. Each group was studied for eight days.

Gymnasieungdomar är en grupp där ett stort antal elever är fysiskt inaktiva. För att öka den fysiska aktiviteten hos elever driver Hallands Idrottsförbund ett projekt där eleverna får möjlighet att spela fotbollsmatch på lektionstid en timma i veckan. Eleverna som deltar i projektet går på en gymnasieskola och har som inriktning el- programmet. Som ett led i utvärderingen av föreliggande projekt genomfördes 10 intervjuer. Studien har som syfte att kartlägga ungdomars motivationsfaktorer och barriärer för att vara fysiskt aktiva och för att delta i ett idrottsprojekt.
