T\u00e4m\u00e4n tutkimuksen tarkoituksena olikin tutkia urheilujuoman nauttimisen vaikutusta plasmatilavuuteen, hemoglobiinikonsentraatioon ja hematokriittiin 11.5 km hiihtokilpailun j\u00e4lkeen. Kahdeksantoista kansallisen tason mieshiiht\u00e4j\u00e4\u00e4 (VOZmax 66 \u00b1 5 ml \u2022 kg--1 \u2022 min-1 ) jaettiin koe- ja kontrolliryhm\u00e4\u00e4n, joissa kummassakin oli yhdeks\u00e4n hiiht\u00e4j\u00e4\u00e4. Kilpailu hiihdettiin Vuokatin hiihtoputkessa, miss\u00e4 ilman l\u00e4mp\u00f6tila oli -5\u00b0C ja ilmarIkosteus noin 80 %. Koeryhm\u00e4 joi yhden litran hypotonista urheilujuomaa 2 h aikana ennen ja 1 h aikana j\u00e4lkeen kilpailun. Kontrolliryhm\u00e4 ei juonut mit\u00e4\u00e4n. Laskimoverin\u00e4ytteet otettiin aamulla 12 h paaston j\u00e4lkeen ja 60 min ennen kilpailua sek\u00e4 0 min, 15 min ja 60 min kilpailun j\u00e4lkeen. Hemoglobiinin ja hematokriitin avulla laskettu plasmatilavuuden lasku oli kilpailun aikana koeryhm\u00e4ll\u00e4 6.0 \u00b1 4.1 % ja kontrolliryhm\u00e4ll\u00e4 7.1 \u00b1 4.4 %. Kilpailua seuranneen 15 min aikana plasmatilavuus palasi kilpailua edelt\u00e4neelle tasolle. Seuraavan 45 min aikana koeryhm\u00e4n plasmatilavuus nousi 11.1 \u00b1 4.0 % ja kontrolliryhm\u00e4n 2.4 \u00b1 5.1 % yli kilpailua edelt\u00e4neen tason. Koe- ja kontrolliryhm\u00e4 erosivat toisistaan plasmatilavuuden muutoksessa vain 60 min kilpailun j\u00e4lkeen (p < 0.001). Urheilujuoman nauttiminen ei vaikuttanut plasmatilavuuden laskuun kilpailun aikana, mutta plasmatilavuuden kasvu suorituksen j\u00e4lkeen oli suurempi, jos urheilujuomaa nautittiin.
