Aihe valittiin, jotta voitaisiin selvitt\u00e4\u00e4, onko live high \u2013 train low -harjoittelulla hy\u00f6tyj\u00e4 maksimaaliseen kest\u00e4vyyssuoritukseen. Lis\u00e4ksi t\u00e4m\u00e4n tutkielman kirjoittajan oma urheilutausta vaikutti aiheen valintaan.\n\nKovalla korkeanpaikan kest\u00e4vyysharjoittelulla ei olla havaittu etua verrattuna kest\u00e4vyysharjoitteluun merenpinnan tasolla. 1990-luvulla korkealla el\u00e4misell\u00e4 ja l\u00e4hemp\u00e4n\u00e4 merenpinnan tasoa treenaamisella eli live high \u2013 train low -harjoittelulla todettiin kuitenkin olevan hy\u00f6ty\u00e4 maksimisuorituskyvyn parantamisessa verrattuna merenpinnan tasolla tapahtuvaan kest\u00e4vyysharjoitteluun. Ymp\u00e4rist\u00f6n hapen osapaine laskee ment\u00e4ess\u00e4 korkeammalle merenpinnan tasosta. Kudosten hapenpuutteen vaikutuksesta punasoluja alkaa muodostumaan luuytimen kantasoluista enemm\u00e4n. Punasolut sis\u00e4lt\u00e4v\u00e4t runsaasti hemoglobiinia eli hapenkuljetuksessa suuressa roolissa olevaa proteiinia. Hengitys- ja verenkiertoelimist\u00f6n sek\u00e4 lihassolujen kyky kuljettaa happea lihassoluihin ja sen k\u00e4ytt\u00e4minen energiantuottoon lihaksissa ovat olennaisimmat tekij\u00e4t, jotka vaikuttavat maksimihapenottokykyyn. Maksimihapenotto puolestaan vaikuttaa maksimisuorituskykyyn, mutta t\u00e4ss\u00e4 tutkielmassa maksimisuorituskyvyll\u00e4 tarkoitetaan p\u00e4\u00e4asiassa suoran hapenoton testin lopetusaikaa sek\u00e4 maksiminopeutta.\n\nTutkimuksessa oli kaksi tutkittavaa ryhm\u00e4\u00e4, joista toinen asui kolmen viikon ajan keskim\u00e4\u00e4rin 18 tuntia vuorokaudesta alppimajassa, jossa hapen osapaine vastasi 2500 metrin korkeutta. Harjoittelu tapahtui merenpinnan tasolla. Toinen ryhm\u00e4 eli kontrolliryhm\u00e4 asui ja harjoitteli koko ajan merenpinnan tasolla. Kaikki tutkittavat olivat kansallisen tai kansainv\u00e4lisen tason hiihtolajien urheilijoita.\n\nTutkimuksen tulosten perusteella kolmen viikon live high \u2013 train low -harjoitusjakso kasvattaa hemoglobiinimassaa tilastollisesti merkitsev\u00e4sti. Kontrolliryhm\u00e4n hemoglobiinimassa puolestaan ei muuttunut tilastollisesti merkitsev\u00e4sti.
