AbstractTitle: Does supplementation with omega 3 improve oxygen uptake among athletes?Author: Jonna Gustafsson and Maria Bohlin Nygren Supervisor: Frode Slinde Examiner: Ingrid Larsson Programme: Programme in dietetics, 180/240 hp Type of paper: Bachelor?s thesis in clinical nutrition, 15 hp Date: May 26, 2015Background: Previous research has shown that omega 3 fatty acids may improve cardiovascular functions by decreased aggregation and increased red blood cell deformability. This produces an increased blood flow and could have a potential effect on oxygen uptake. Optimal aerobic capacity is a determinant factor of performance within endurance exercise.Objective: To compile scientific research of the possibility that omega 3 supplementation could improve oxygen uptake among athletes.Search strategy: The literature research is based on searches in PubMed and Scopus with the terms ?Physical Endurance?, ?Oxygen Consumption?, ?Fatty Acids Omega 3?, ?Dietary Supplements?, ?Exercise?, ?Fatty Acids Essential?, ?Docosahexaenoic Acids?, ?Eicosanoic Acids?, ?Fish Oils?, ?oxygen consumption?, ?maximal oxygen consumption?, ?VO2 max?, ?athlete?, ?omega-3 supplementation?, ?physical endurance?, ??-3?, ?omega-3?, ?Maximal Aerobic Power?, ?Oxygen Uptake?, ?VO2? and ?Maximal Aerobic Capacity?.Selection criteria: Randomized controlled trials (RCT) with an intervention of omega 3-supplementation during three weeks or more were included.

Syfte och frågeställningarMin avsikt med studien var att undersöka yngre elevers (8-10 år) attityder och upplevelser av fysisk aktivitet, samt vilken roll barnen tilldelar fysisk förmåga och upplevd fysisk självkänsla vid spel och lekar tillsammans med andra barn.MetodUrvalet bestod av 12 elever, 8-10 år med vilka en semistrukturerad intervju genomfördes. Vid intervjun användes bilder som föreställde barn i olika situationer. Utöver Intervjun genomfördes en föräldraenkät för att få en bakgrundsinformation om föräldrarnas syn på barnens fysiska aktivitet och deras egna motionsvanor. Intervjusvaren bearbetades utifrån frågeställningarna, analyserades och tolkades med utgångspunkt från ett interaktionistiskt perspektiv.ResultatEleverna beskriver den egna fysiska självkänslan i termer av god idrottslig motorisk kompetens. Då respondenterna resonerar kring andras goda kompetenser beskrivs dessa i termer av fysisk styrka och kondition.

An increasing number of health problems in the population and an uneven distribution of health between different groups in the society, have been identified as a problems and has therefore been put on the political agenda in Sweden. Thus, the purpose of this thesis is to estimate and discuss the significance an individual?s behaviour, in a number of areas, has on his/her level of health.The empirical material for this thesis is taken from a nationwide inquiry conducted in 2004,which was called ?Hälsa på lika villkor?? (Health on equal terms?) The material used consists of the answers and records from individuals living in the administrative district of Kronoberg. 9972 individuals were included in the sample and the answering frequency was 63,2%. To map and analyse the material, which was done mainly through crosstabs, chi-square tests and logistic regressions, the statistics software SPSS 11.5 was used.The parameter used to measure the health level is the individual?s own perception of his or her general health.
