Abstract [sv]

Koffein har sedan 1962 fram och tillbaka varit dopingklassat men är sedan 2004

ett tillåtet ergogent preparat inom idrotten. Flera studier har visat positiva

resultat i uthållighetsidrotter och på maximal styrkeförmåga. Syftet med denna

studie var att se om koffein har någon ergogen effekt på power i

överkroppsmuskulaturen. I denna studie användes en dubbel-blindad,

randomiserad cross-over design. En slumpmässig indelning inför det första

testtillfället avgjorde ifall deltagarna började studien med koffein- eller

placebosupplementering och bytte sedan supplementering inför testtillfälle två.

Som supplementeringsmetod användes koffein i tuggummiform på grund av att

det ger ett snabbare upptag. Power mättes genom testet sittande stöt med en

kula på 5 kg. Resultatet visar på en mycket svag (ES=0,13) positiv förbättring av

stötlängderna mellan interventionerna. En av anledningarna till det triviala

resultatet tros kunna bero på att det urval som användes ej bestod av en

homogengrupp vad gäller träningsbakgrund och prestationsnivå. På grund av

detta är det svårt att dra några slutsatser om koffeinet har eller inte har några

ergogena effekter på power i överkroppen.

Abstract [en]

Since 1962 Caffeine has been off and on the doping classification list, since 2004,

it has been permitted as an ergogenic agent in sport. Several studies have shown

positive ergogenic effects in endurance sports and in maximum strength

capacity. The purpose of this study was to determine if caffeine has any

ergogenic effect on power in the upper body. In this study, a double-blind,

randomized cross-over design was used. Participants were randomly selected to

start the intervention with either caffeine or placebo supplementation and then

have the alternative supplementation before a second test, held after a 48 hour

washout period. A supplementation method Caffeinated chewing gum was used

as a supplementation method due to its faster uptake by the body. The distance

that a 5 kg shot put could be launched from a sitting position was used as a

measure of upper body power. The results showed a 1,7 % but trivial (ES = 0.13)

difference in shot put lengths between the interventions, in favour of the caffeine

intervention. One of the reasons for the lack of a clear ergogenic effect is believed

to be due to the non-homogenous group, in terms of training background, level of

performance and the resulting low level of within-participant reliability. Because

of this it is difficult to draw any conclusions regarding caffeine and its ergogenic

effects on power in the upper body.
