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…
Validation in Young Soccer Players of the Modified Version of the Harre Circuit Test: The Petrucci Ability Test
2021
The evaluation of soccer players’ physical fitness from youth onward is important for monitoring performance and planning training. While health-related factors present valid and reliable tests, the skill-related component should be studied in depth. An interesting test to evaluate the skill-related factors is the Harre circuit test (HTC); unfortunately, this test includes the somersault, an element not present in soccer. The aim of the present study is the validation of the Petrucci ability test (PAT), a variation of the HTC without the somersault for young soccer players. Children and adolescents (age range 10–13 years old) soccer players concluded the 20-m, the HTC and the PAT. To establ…
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…
Hierarkiat yläkoulun kaveriporukoissa : nuoren kokema sosiaalinen asema ja liikkuminen
2021
The low level of physical activity among young people has become a common societal concern. This study sought new information on the backgrounds of adolescents’ physical activity. The aim was to find out whether the adolescents’ subjective social status is related to physical activity. The data were collected as part of the follow-up research and evaluation of the Finnish Schools on the Move programme in 2012–2015. The data were collected through student surveys, measuring adolescents’ physical activity with accelerometers, and observing and interviewing secondary school students. The associations between adolescents’ subjective social status and physical activity, as well as the factors re…
Long-term changes in pigmentation of arctic Daphnia provide potential for reconstructing aquatic UV exposure
2016
Abstract Despite the biologically damaging impacts of solar ultraviolet radiation (UV) in nature, little is known about its natural variability, forcing mechanisms, and long-term effects on ecosystems and organisms. Arctic zooplankton, for example the aquatic keystone genus Daphnia (Crustacea, Cladocera) responds to biologically damaging UV by utilizing photoprotective strategies, including pigmentation. We examined the preservation and content of UV-screening pigments in fossil Daphnia remains (ephippia) in two arctic lake sediment cores from Cornwallis Island (Lake R1), Canada, and Spitsbergen (Lake Fugledammen), Svalbard. The aims were to document changes in the degree of UV-protective p…
Obesity and survival in operable breast cancer patients treated with adjuvant anthracyclines and taxanes according to pathological subtypes: a pooled…
2013
Obesity is an unfavorable prognostic factor in breast cancer (BC) patients regardless of menopausal status and treatment received. However, the association between obesity and survival outcome by pathological subtype requires further clarification. METHODS: We performed a retrospective analysis including 5,683 operable BC patients enrolled in four randomized clinical trials (GEICAM/9906, GEICAM/9805, GEICAM/2003-02, and BCIRG 001) evaluating anthracyclines and taxanes as adjuvant treatments. Our primary aim was to assess the prognostic effect of body mass index (BMI) on disease recurrence, breast cancer mortality (BCM), and overall mortality (OM). A secondary aim was to detect differences o…
