Tutkimuksen koehenkil\u00f6t olivat 35 suomalaista nuorta (14.14 \u00b10.71 vuotta, 23 tytt\u00f6\u00e4 & 12 poikaa), otanta laajemmasta AFIS (Active, Fit and Smart) -tutkimusprojektista.

Tutkimuksessa havaittiin fyysisell\u00e4 aktiivisuudella olevan positiivinen yhteys oikean parahippokampaalisen korteksin paksuuteen [F(1, 30)=4.44, p<0.05)]. Fyysisesti aktiivisilla henkil\u00f6ill\u00e4 oikea parahippokampaalinen korteksi oli paksumpi verrattuna v\u00e4hemm\u00e4n aktiivisiin henkil\u00f6ihin.

Fyysisesti aktiivisemmilla henkil\u00f6ill\u00e4 vasen parasentraalinen korteksi oli paksumpi kuin v\u00e4hemm\u00e4n aktiivisilla henkil\u00f6ill\u00e4, mutta vanhemmilla koehenkil\u00f6ill\u00e4 korteksi oli ohuempi kuin nuoremmilla.

The current study examined whether physical activity or physical fitness is related to regional brain volume or cortical thickness in youth. The subjects were 35 Finnish adolescents (14.14 \u00b10.71 years, 23 females & 12 males), a subsample from Active, Fit and Smart (AFIS) \u2013 research project. Measurements included objective physical activity measurement with accelerometers, physical fitness test battery and brain imaging procedure with magnetic resonance imaging (MRI). From the larger study sample of the AFIS \u2013 research project, two groups were formed based on the physical activity measurements, active (n=18) and non-active (n=17). The active group included the most physically active subjects, measured as the average daily time involved in moderate-to-vigorous activity, and the non-active group included the most inactive subjects. The relationship between physical activity and brain morphology was examined by comparing the two groups using the analysis of covariance, controlling the effect of age, puberty status and body mass index. The relationship between physical fitness and brain morphology was examined by looking at correlations between the physical fitness tests and chosen brain variables. It was found, that physical activity had a positive relationship with the thickness of the right parahippocampal cortex [F(1, 30)=4.44, p<0.05)]. Physically more active subjects expressed a thicker right parahippocampal cortex compared to less active subjects. A relationship was also found between physical activity and the thickness of the left paracentral cortex, yet this finding lost significance after controlling the effect of age [F(1, 30)=2.50, p=0.12)]. Physically more active subjects expressed a thicker left paracentral cortex than less active subjects, whereas older subjects expressed a thinner left paracentral cortex compared to younger subjects. No other brain region displayed a connection with the level of physical activity and no significant correlations were detected between different components of physical fitness and the brain variables. These findings imply that the area of right parahippocampal cortex might be especially susceptible to physical activity induced changes in youth, and that physical activity does not necessarily have to improve physical fitness to cause changes in brain morphology.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Riikka Pasanen (risopasa) on 2017-06-21 10:00:20.714958.
