Mobility recovery after hip fracture and effects of a multi-component home-based rehabilitation program
2014
Maantieteelliset piirteet ja iäkkäiden henkilöiden liikkuminen ulkona (GEOage)
2021
This dataset is part of the “Geographic characteristics, outdoor mobility and physical activity of older people” (GEOage) project, in which freely available geographic information characterizing the environment is linked to participant data of the “Life-space mobility in old age” (LISPE) cohort comprising 75–90-years-old community-dwelling people living in Jyväskylä and Muurame in Central Finland (n=848). The GEOage dataset contains variables of environmental characteristics of participants' environment within 500 or 1000 m from home. The dataset comprises variables related to characteristics of nature (hilliness, nature and green areas, waterside areas) and built environment (land use, nei…
Indeksi liikuntaympäristöjen monipuolisuudesta asukkaiden lähialueella
2023
Liikunta on välttämätöntä terveyden ylläpitämiselle, ja sillä on lukemattomia positiivisia vaikutuksia sekä fyysiseen että psyykkiseen hyvinvointiin. Liikuntaympäristöjen monipuolisuus lähellä kotia voi edistää liikunnan harrastamista ja fyysisesti aktiivista elämäntapaa. Liikunnallisen elämäntavan mahdollistaminen kaikille, etenkin huono-osaisilla alueilla, voi tasoittaa alueiden välisiä hyvinvointieroja ja näin vähentää segregaation vaikutuksia. Suomessa yhdenvertaisten liikuntapalvelujen järjestäminen asukkaille on pääosin kuntien vastuulla. Tässä artikkelissa esittelemme uuden indeksin, jolla voidaan kuvata ja analysoida asukkaiden lähialueella olevien erityyppisten liikuntaympäristöjen…
Closed due to COVID-19: effects of indoor sports restrictions on suburban adults’ physical activity behaviours
2023
During the COVID-19 pandemic, people have been required adaptations in leisure-time physical activity (PA) especially due to restrictive policies concerning indoor sport facilities (ISF). This study investigated the effects of the constraints on ISF among residents of two low socioeconomic status suburbs in Finland. Research questions were: (1) Are sociodemographic characteristics associated with a reduced use of ISF during the pandemic? (2) Are sociodemographic characteristics associated with changes in the overall PA amount among those respondents with a reduced use of ISF? (3) Is the reduced use of ISF associated with an increased use of other PA environments (home environment, built out…
Antioxidant Potential of Extracts Obtained from Macro- (Ascophyllum nodosum, Fucus vesiculosus and Bifurcaria bifurcata) and Micro-Algae (Chlorella v…
2018
Background: Natural antioxidants, which can replace synthetic ones due to their potential implications for health problems in children, have gained significant popularity. Therefore, the antioxidant potential of extracts obtained from three brown macroalgae (Ascophyllum nodosum, Fucus vesiculosus and Bifurcaria bifurcata) and two microalgae (Chlorella vulgaris and Spirulina platensis) using ultrasound-extraction as an innovative and green approach was evaluated. Methods: Algal extracts were obtained by ultrasound-assisted extraction using water/ethanol (50:50, v:v) as the extraction solvent. The different extracts were compared based on their antioxidant potential, measuring the extraction …
Effects of physical activity on neural markers of attention in children
2016
Huoli passiivisen elämäntavan vaikutuksista oppimisen edellytyksiin on kasvanut, kun lasten fyysinen aktiivisuus on vähentynyt. Useat tutkimukset tukevat fyysisen aktiivisuuden suojaavaa vaikutusta erilaisiin kognitiivisiin toimintoihin. Tarkkaavaisuuden kohdistaminen relevantteihin ärsykkeisiin näyttää olevan merkittävä osa oppimista, minkä vuoksi mielenkiinto on kohdistettu nykytutkimuksessa tarkkaavaisuuden mekanismeihin. Alfa-oskillaatioiden inhibitorinen rooli tarkkaavaisuudessa on saanut vahvistusta spatiaalista tarkkaavaisuutta selvittäneistä tutkimuksista. Alfa-oskillaatioiden on havaittu lateralisoituvan siten, että alfa-aktiivisuus laskee näköärsykettä prosessoivalla aivokuorella …
Somatosensory evoked fields after exercise induced pain
2017
The amount of research utilizing magnetoencephalography (MEG) has increased within the last few decades because of the development and better availability of equipment. With MEG, different areas of brain functionality can be studied in a variety of tasks and pathologies. Somatosensory evoked fields (SEF) are magnetic fields generated by tens of thousands of neurons firing in the primary somatosensory cortex. The purpose of this master’s thesis is to study the modulation of SEFs after exercise induced pain. The study was carried out in Jyväskylä Centre for Interdisciplinary Brain Research (CIBR). The study subjects (N=18, male 10, female 8) were healthy and suitable for MEG measurements. Dat…
Dynamics of brain activation during learning of syllable-symbol paired associations.
2019
| openaire: EC/H2020/641652/EU//ChildBrain Initial stages of reading acquisition require the learning of letter and speech sound combinations. While the long-term effects of audio-visual learning are rather well studied, relatively little is known about the short-term learning effects at the brain level. Here we examined the cortical dynamics of short-term learning using magnetoencephalography (MEG) and electroencephalography (EEG) in two experiments that respectively addressed active and passive learning of the association between shown symbols and heard syllables. In experiment 1, learning was based on feedback provided after each trial. The learning of the audio-visual associations was c…
Automatic Processing of Changes in Facial Emotions in Dysphoria: A Magnetoencephalography Study
2018
It is not known to what extent the automatic encoding and change detection of peripherally presented facial emotion is altered in dysphoria. The negative bias in automatic face processing in particular has rarely been studied. We used magnetoencephalography (MEG) to record automatic brain responses to happy and sad faces in dysphoric (Beck’s Depression Inventory ≥ 13) and control participants. Stimuli were presented in a passive oddball condition, which allowed potential negative bias in dysphoria at different stages of face processing (M100, M170, and M300) and alterations of change detection (visual mismatch negativity, vMMN) to be investigated. The magnetic counterpart of the vMMN was el…
Physical activity and aerobic fitness show different associations with brain processes underlying anticipatory selective visuospatial attention in ad…
2021
ABSTRACTUnderlying brain processes of exercise-related benefits on executive functions and the specific contribution of physical activity vs. aerobic fitness are poorly understood, especially during adolescence. We explored whether and how physical activity and aerobic fitness are associated with selective attention and the oscillatory dynamics induced by an anticipatory spatial cue. Further, we studied whether the link between physical exercise level and cognitive control in adolescents is mediated by the task-related oscillatory activity. Magnetoencephalographic alpha oscillations during a modified Posner’s cueing paradigm were measured in 59 adolescents (37 females and 22 males, 12 to 17…
