A systematic overviewAuthor: Irene Eriksson and Alexandra ÖquistSupervisor: Henriette PhilipsonExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 09, 2014Background: During physical exercise, it is common with dehydration, which affectsperformance negatively. To restore the fluid balance it is optimal to drink fluids containingsalt and carbohydrates. In theory, coconut water should be a good recovery drink because oftheir nutrient content.Objective: To evaluate the scientific evidence available, to investigate whether coconut wateris better than water or sports drinks for rehydration after physical exercise.Search strategy: PubMed, Scopus and Cochrane Library have been used in the literarysearch. Keywords used were recovery, fluid balance, fluid therapy, water-electrolyte balance,rehydration, dehydration, hydration, exercise, physical activity, resistance training, activity,sports, training, coconut water in varying combinations, in order to cover as wide area aspossible. MeSH terms and translation software have been used.Selection criteria: Human studies of RCTs published in English or Swedish. Studiesconducted in healthy adults (> 19 years) were included. Articles published more than 15 yearsago and articles where dehydration is not due to physical activity were excluded.Data collection and analysis: Three RCTs were included for review and assessment. Qualitywere examined using SBUs "Mall för kvalitetsgranskning av randomiserade studier".Evidence Grading for the selected outcome measures was based on "Summary of evidenceforms" based on GRADE.Main results: Three trials were included and form the basis of the results of this reviewarticle. One study indicates that coconut water had better fluid retention than water afterphysical activity. Other studies show no significant difference between the drinks.Conclusions: After having reviewed and assessed the existing literature available on thesubject, the conclusion is that there is moderate evidence that coconut water is not preferableto water or sports drinks as recovery drink after physical exercise.
