Predicting Change in Middle School Students’ Leisure-Time Physical Activity Participation: A Prospective Test of the Trans-Contextual Model
2020
We applied the trans-contextual model (TCM) to examine the effects of middle school students’ perceived autonomy support from their physical education (PE) teachers on autonomous motivation toward PE in school and, critically, autonomous motivation toward, and actual participation in, leisure-time physical activity (PA). The research adopted a three-wave prospective design enabling the modeling of change in the TCM constructs over time. Middle school students (N = 248) aged from 12 to 16 years reported their perceived autonomy support, autonomous motivation in PE, autonomous motivation toward leisure-time PA, attitudes, subjective norms, perceived behavioral control (PBC), intentions for PA…
Effect of self-determined motivation in physical education on objectively measured habit physical activity : a trans-contextual model
2019
Grounded in the trans-contextual model, the purpose of the present study was to examine the role of self-determined motivation in Physical Education (PE) on self-determined motivation in Physical Activity (PA), PA intention, and accelerometer-measured habitual PA behavior among high-school aged adolescents. A sample of 394 Spanish high-school students (211 males and 183 females; aged 12-16 years) participated in the present study. The outcome measure of PA was established using accelerometry, whereas motiva- tion toward PA and PE as well as PA intention were measured using validated questionnaires. Path analyses supported in part the central propositions of the trans-contextual model. Self-…
Koululaisten fyysisen aktiivisuuden ja liikuntatunneilla koetun autonomian muutokset 7. luokalta 9. luokalle
2010
Tutkimuksen tarkoituksena oli analysoida koululaisten fyysisen aktiivisuuden ja liikuntatunneilla koetun autonomian muutoksia 7. luokalta 9. luokalle. Lisäksi tutkittiin liikuntatunneilla koetun autonomian yhteyttä fyysiseen aktiivisuuteen. Tutkimuksen osanottajiksi valittiin 639 (tytöt = 296, pojat = 343) keskisuomalaista koululaista, jotka olivat tutkimuksen alkaessa seitsemäsluokkalaisia. Tutkimukseen osallistui 8 koulua ja 32 opetusryhmää. Pitkittäisaineisto kerättiin 2007–2009 viidellä mittauskerralla, jotta alakoulusta yläkouluun siirtymisen jälkeistä kehitystrendiä voitiin seurata. Mittaukset suoritettiin strukturoiduilla kyselyillä. Oppilaiden itseraportoitua fyysistä aktiivisuutta …
Students' Physical Activity, Physical Education Enjoyment, and Motivational Determinants through a Three-Year School-Initiated Program
2023
Patterns of physical activity in adulthood are often established during adolescence, making this an important period for promoting physical activity. To address this, the Sotkamo Physical Activity as Civil Skill Program 2010–2014 was implemented to increase Grade 5 to 9 students’ physical activity on a daily basis. The purpose of this study was to examine the effects of program on students’ physical activity and enjoyment. Furthermore, the relationship between motivational climate and enjoyment, and the percentages of students who engaged in 60 minutes of moderate to vigorous physical activity on the daily basis were examined.
Motor Coordination and Global Development in Subjects with Down Syndrome: The Influence of Physical Activity
2022
Background: Many research studies have investigated motor impairments and delayed development in children with Down Syndrome (DS). However, very few studies detected these features in adults with DS. Hence, this study aimed to investigate the relationship between motor coordination and global development in subjects with DS, including adults. Furthermore, the second aim was to detect any differences in motor coordination and global development as a function of the practice of physical activity (PA) in this population. Methods: Twenty-five participants with DS (10 f, 15 m), with a chronological mean age of 27.24 years and development mean age of cognitive area of 4.93 years, were enrolled an…
Motywacja w sporcie i aktywności fizycznej
2018
Problematyka dotycząca motywacji w aktywności sportowej jest przedmiotem rozważań naukowych i mocno eksplorowanym obszarem zainteresowań wielu badaczy. Chociaż aktualnie można odnaleźć sporo teorii odnoszących się do motywacji i jej związków z różnymi cechami, to teoria samodeterminacji wydaje się mieć największe zastosowanie na gruncie empirycznym. W prezentowanym rozdziale przedstawiono ramy teoretyczne teorii samodeterminacji (samookreślenia) oraz dokonano przeglądu badań opartych o ten model teoretyczny zarówno w obszarze sportu wyczynowego, jak i rekreacyjnej aktywności fizycznej.
Laboratory-Based Gait Variability and Habitual Gait Entropy Do Not Differentiate Community-Dwelling Older Adults from Those with Subjective Memory Co…
2020
Background Age-related cognitive decline may be delayed with appropriate interventions if those at high risk can be identified prior to clinical symptoms arising. Gait variability assessment has emerged as a promising candidate prognostic indicator, however, it remains unclear how sensitive gait variability is to early changes in cognitive abilities. Research question Do community-dwelling adults over 65 years of age with subjective memory complaints differ from those with no subjective memory concerns in terms of laboratory-measured or free-living gait variability? Methods This cross-sectional study recruited 24 (age = 73.5(SD 6.4) years) community-dwelling people with subjective memory co…
Application of Molecular Topology for the Prediction of Reaction Yields and Anti-Inflammatory Activity of Heterocyclic Amidine Derivatives
2011
Topological-mathematical models based on multiple linear regression analyses have been built to predict the reaction yields and the anti-inflammatory activity of a set of heterocylic amidine derivatives, synthesized under environmental friendly conditions, using microwave irradiation. Two models with three variables each were selected. The models were validated by cross-validation and randomization tests. The final outcome demonstrates a good agreement between the predicted and experimental results, confirming the robustness of the method. These models also enabled the screening of virtual libraries for new amidine derivatives predicted to show higher values of reaction yields and anti-infl…
Paving the way of systems biology and precision medicine in allergic diseases: The MeDALL success story
2016
MeDALL Mechanisms of the Development of ALLergy; EU FP7-CP-IP; Project No: 261357; 20 (10) -2015 proposed an innovative approach to develop early indicators for the prediction, diagnosis, prevention and targets for therapy(.) MeDALL linked epidemiological, clinical and basic research using a stepwise, large-scale and integrative approach: precisely phenotyped children followed in 14 birth cohorts spread across Europe were combined with systems biology omics, IgE measurement using micro-arrays and environmental data(.) Multimorbidity in the same child is more common than expected by chance alone, suggesting that these diseases share causal mechanisms irrespective of IgE sensitisation(.) IgE …
