Physical Activity in Peri-Urban Communities: Testing Intentional and Implicit Processes within an Ecological Framework.

2020

Background Given the substantive health inequalities in peri‐urban communities and the potential for physical activity to promote health in these communities, identifying modifiable physical activity determinants in this population is important. This study explored effects of the peri‐urban environment and psychological constructs on physical activity intentions and behavioural automaticity guided by an integrated theoretical framework. Methods Peri‐urban Australians (N = 271) completed self‐report measures of environmental (i.e. physical/social environment, and neighbourhood selection), motivational (i.e. autonomous motivation), and social cognition (i.e. attitudes, norms, and perceived be…

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…

Perceptions about physical activity and its associated benefits among employees : case study in 12 Multinational Companies in Pakistan

2016

This thesis focus on the perceptions of the employees working in Multinational Corporations (MNCs) in Pakistan, with regards to their physical activity and its associated benefits. Previous research has shown that physical activity is positively associated with on-job productivity and life satisfaction of the employees across the world. With no such research being carried out in Pakistan before, this thesis aims to focus on the same factors, but uses employees’ perceptions rather than employing an intervention study. Furthermore associated benefits of physical activity such as reduced healthcare cost, decrease in exposure to various heath-risks and reduced presenteeism were also addressed w…

Myostatin/activin blocking combined with exercise reconditions skeletal muscle expression profile of mdx mice

2015

Duchenne Muscular Dystrophy is characterized by muscle wasting and decreased aerobic metabolism. Exercise and blocking of myostatin/activin signaling may independently or combined counteract muscle wasting and dystrophies. The effects of myostatin/activin blocking using soluble activin receptor-Fc (sActRIIB-Fc) administration and wheel running were tested alone or in combination for seven weeks in dystrophic mdx mice. Expression microarray analysis revealed decreased aerobic metabolism in the gastrocnemius muscle of mdx mice compared to healthy mice. This was not due to reduced home-cage physical activity, and was further downregulated upon sActRIIB-Fc treatment in enlarged muscles. However…
