Unen laadun ja pituuden vaikutukset fyysiseen aktiivisuuteen ja submaksimaaliseen aerobiseen kestävyyteen
Abstract
Tämän tutkimuksen tarkoituksena oli tutkia unen laadun ja pituuden sekä näiden yhteisvaikutuksia fyysiseen aktiivisuuteen. Lisäksi tarkasteltiin yhden yön unen laadun ja pituuden vaikutusta seuraavana päivänä tapahtuvaan submaksimaaliseen aerobiseen kestävyyssuoritukseen.
Tutkimus suoritettiin Kainuun prikaatissa ja tutkimukseen osallistui 33 sotilaspalvelukseen astunutta suomalaista varusmiestä (ikä 20 ± 0.3 vuotta). Tutkimusaineisto kerättiin kahdeksan viikon sotilaallisen peruskoulutuksen palvelusviikkojen kaksi, neljä ja kahdeksan mittausaineistosta. Viikkojen kaksi ja neljä peruskoulutus tapahtui varuskunnan alueella ja viikon kahdeksan maasto-olosuhteissa. Tutkittavien unen laatu ja pituus sekä päivän aikana tapahtuva fyysinen aktiivisuus mitattiin aktiivisuusmittarilla (Polar AW200 Activity Monitor). Submaksimaalinen aerobinen suorituskyky arvioitiin 45 minuutin submaksimaalisen marssitestin sykkeen ja veren laktaatin vastearvoista.
Tämän tutkimuksen tulokset viittaavat siihen, että unen laadulla ja pituudella eikä niiden yhteisvaikutuksella ole vaikutusta seuraavana päivänä tapahtuvaa fyysiseen aktiivisuuteen varusmieskoulutuksen aikana. Unen laadulla ei ole myöskään vaikutusta sydämen sykkeeseen ja veren laktaattien vastearvoihin submaksimaksimaalisessa aerobisessa kestävyyssuorituksessa. Sen sijaan pitkä uni korreloi negatiivisesti submaksimaalisen kuormituksen laktaattivasteeseen siten, että mitä pitempi uni sitä alhaisempi veren laktaattipitoisuus.

The purpose of this study was to evaluate the quality and length of the sleep and their interaction on physical activity. Secondly, the purpose was to evaluate the effect of the previous night sleep quality and length on the next day submaximal aerobic endurance performance. The study was conducted in the Kainuu Brigade among 33 Finnish conscripts (aged 20 ± 0.3 yrs.). The data were collected during the second, fourth and eighth week of basic military training. Training during the weeks two and four was performed in the Kainuu Brigade area and at week eight conscripts had four day field training. The quality and length of the sleep and the physical activity were measured with the Polar activity monitor (Polar AW200 Activity Monitor). The submaximal aerobic performance was evaluated by heart rate and blood lactate responses during the 45-minute submaximal marching test. The results of this study indicated that the interaction of quality and length of sleep has no effect on the next day physical activity. Furthermore, the length of sleep had no effect on heart rate and blood lactate response of the submaximal marching test. However, the length of sleep correlated negatively with the blood lactates at the end of submaximal marching test. Keywords: quality of sleep, sleep length, physical activity, endurance
