Applying UTAUT2 to Explain the Use of Physical Activity Logger Applications Among Young Elderly
2020
Digital wellness technologies have been proposed as a promising way to promote the levels of physical activity and to solve the prevalent problem of physical inactivity among elderly people. In this study, we propose and test a research model for explaining the acceptance and use of these technologies in the case of the young elderly segment (people aged 60–75 years) and physical activity logger applications. The proposed model is theoretically founded on UTAUT2, and it is empirically tested by using the data collected from 115 Finnish young elderly users of a physical activity logger application and analysed with partial least squares based structural equation modelling (PLS-SEM). We find …
Sustainable Physical Activity Programs for Young Elderly : A Fuzzy Analytic Hierarchy Process Approach
2020
Physical activity (PA) programs are useful to help young elderly stay in good shape for their senior years. These programs should be sustainable, as this would keep the users active for months and years. A PA program should build on activities that users find meaningful and/or best suited for their history of sports and exercise as well as their present physical capacity. The challenge is to make the best selection from a (long) list of possible activities. We worked out a method to help young elderly to build a sustainable PA program from a set of activities that experts have identified as contributing to health and fitness among young elderly. The method builds on the Analytical Hierarchy…
Modelling the influence of automaticity of behaviour on physical activity motivation, intention and actual behaviour
2014
In research and in practise social-cognitive models, such as the theory of planned behaviour (TPB), are used to predict physical activity behaviour. These models mainly focus on reflective cognitive processes. As a reflective process, intention is thought to be the most proximal predictor to behaviour. Nevertheless, research suggests that the relation between intention and actual behaviour, the so called intention-behaviour gap, is moderate. Many health-related actions in daily life are performed repetitively and with minimal forethought. In contrast to social-cognitive theories, dual-process theories suggest that behaviour is based on both reflective and automatic processes. Recent researc…
Grit og fysisk aktivitet : Utviklingen av grit ved endring av fysisk aktivitetsnivå blant norske ungdommer: En to-års oppfølgingsstudie
2017
Masteroppgave folkehelsevitenskap ME516 - Universitetet i Agder 2017 The purpose of the study was to investigate the development of grit due to changes in physical activity in Norwegian youth. In addition, the study wanted to investigate differences in grit based on school type (age) and gender. This longitudinal study is part of a larger project called "The Relevance of Physical Activity Contexts in the Daily Life of Adolescents" (REPAC). The study is based on data from two time points (2014 and 2016). The sample consisted of students from Oslo/Akershus, Østfold and Agder. 1658 (54.4% from first measurement point) students were included in the study. To investigate grit and physical activi…
Longitudinal associations among cardiorespiratory fitness and objectively measured moderate-to-vigorous physical activity of Finnish schoolchildren
2022
Children and adolescents' engagement in physical activity has decreased in most Western countries across the previous three decades. Therefore, increasing number of researchers are investigating antecedents of physical activity engagement in childhood and adolescence. This longitudinal study investigated if cardiorespiratory fitness measured at Grade 5 explained objectively measured moderate-to-vigorous physical activity (MVPA) at grade 7. nonPeerReviewed
Actividad física y uso sedentario de medios tecnológicos de pantalla en adolescentes
2013
Los beneficios asociados a un estilo de vida activo adquieren una especial importancia cuando nos referimos a niños y jóvenes por sus repercusiones a corto y a largo plazo, de modo que convierten a la actividad física en un elemento clave para las políticas sociales y de salud de las distintas administraciones públicas. A la preocupación que suscita la práctica física entre los adolescentes, se le añade el uso creciente de los medios tecnológicos de pantalla por parte de la población joven, que puede mermar o condicionar su práctica física diaria. La presente tesis doctoral consiste en una investigación epidemiológica sobre una muestra representativa de adolescentes españoles que ascendió a…
"Me ollaan koko ajan liikkeessä" : tutkimus nuorten omaehtoisen liikkumisen muodoista ja merkityksistä tilan kehyksissä
2017
This study examines the meanings and prerequisites of self-organised physical activity from young people’s perspective. The theoretical framework is social space, which enables young people’s experiences to be interpreted in parallel with their physical, social, and cultural environment. Three research questions are addressed: (1) Where does young people’s self-organised physical activity take place? (2) What are the forms of the activity? (3) What meanings do young people associate with the spaces of the activity? The research data were collected within one municipality. The main data consist of 34 theme interviews with young people aged 12 to 16 years. The interviewees were selected mainl…
Chemical composition and biological activity of the essential oil of Ballota hispanica (L.) Benth. growing wild in Sicily
2015
Ballota L. comprises several relevant species largely used for their excellent therapeutic properties. Ballota hispanica (L.) Benth. is widely used in herbal medicine, and it is sold in herbalist shops for its sedative and antispasmodic properties. Considering its traditional medicinal use and the lack of scientific studies on the volatile components of this species as well as on its biological activities, in this study the chemical composition of the essential oil from aerial parts of B. hispanica, collected in Sicily, was evaluated by gas chromatography and gas chromatographyâmass spectrometry. α-Elemol was the most abundant component of the oil (10.9%), followed by α-ylangene (8.5%),…
RUOLO DI β-GLUCOSIDASI ISOLATA D’ATTIVITÀ ENZIMATICHE COLLATERALI SUL RILASCIO DI TRANS-RESVERATROLO NEI VINI

Characterization and antimicrobial activity of the volatile components of the flowers of Magydaris tomentosa (Desf.) DC. collected in Sicily and Alge…
2014
The essential oils of the flowers of Magydaris tomentosa (Desf.) DC. (Apiaceae) collected in Sicily (MSi) and Algeria (MAl), respectively, were obtained by hydrodistillation, and their compositions were analysed. The analyses allowed the identification and quantification of 23 components in MSi and 60 compounds in MAl, respectively, showing a very different profile in the composition of the two populations. The main components of MSi were cembrene (28.2%), α-springene (17.5%) and β-springene (14.8%), also present in MAl but in lesser amount (0.4%, 1.8% and 0.9%, respectively), whereas the principal constituents of MAl were (E)-nerolidol (35.4%), α-costol (13.3%) and β-costol (6.8%). Both MS…
