Effects of intrinsic aerobic capacity, aging and physical activity on interleukin-15 protein level in serum and skeletal muscle

2015

Myokines are cytokines and other peptides produced in muscle that can transmit autocrine, paracrine or endocrine signals to other tissues. This is a potential way for exercise to carry out its beneficial effects on different parts of the body. Interleukin-15 (IL-15) is a myokine that has been shown to exert beneficial effects on multiple tissues: skeletal muscle, adipose tissue, bone and skin. Muscle-derived IL-15 signaling remains to be fully elucidated. It is known that the expression and signaling is affected by aging, exercise, and intrinsic aerobic capacity. The purpose of this study was to assess the effects of intrinsic aerobic capacity, aging and physical activity separately and in …

Effect of physical activity councelling on disability in older people: A 2-year randomized controlled trial.

2008

OBJECTIVES: To study the effect of a physical activity counseling intervention on instrumental activity of daily living (IADL) disability. DESIGN: Primary care–based, single-blind, randomized controlled trial. SETTING: City of Jyväskylä, central Finland. PARTICIPANTS: Six hundred thirty-two people aged 75 to 81 who were able to walk 500 meters without assistance, were at most moderately physically active, had a Mini-Mental State Examination score greater than 21, had no medical contraindications for physical activity, and gave informed consent for participation. INTERVENTION: A single individualized physical activity counseling session with supportive phone calls from a physiotherapist ever…

Mother's and daughter's : interplay of physical activity with personal, behavioral, and environmental factors

2017

The purpose of this study was to explore the family dynamics in order to further understand and discover through interviews a parent and their children's behaviors in the topic area of physical activity choices. A narrative case study approach was taken to look into each family's experiences in order to better understand their motivations behind physical activity and to make conclusions of the social, environmental, and behavioral dynamics. Semi-structured interviews were completed with the parent and then with the child individually for a total of three families and four children. Family A is from South Korea living in Finland, family B is from Finland and living in Finland, family C is or…

Association of military training with oxidative stress and overreaching.

2011

ABSTRACT: We hypothesized that increased oxidative stress and disrupted redox balance may be predisposing factors and markers for overreaching (OR). Purpose: The study's purpose was to examine whether oxidative stress markers and antioxidant status and physical fitness are related to OR during an 8-wk military basic training (BT) period. Methods: Oxidative stress and antioxidant status were evaluated in the beginning and after 4 and 7 wk of training in 35 males (age = 19.7 ± 0.3 yr) at rest and immediately after a 45-min submaximal exercise. Physical activity (PA) was monitored by an accelerometer throughout BT. Indicators of OR were also examined. Results: From baseline to week 4, increase…

Snacktivity™ to promote physical activity and reduce future risk of disease in the population: protocol for a feasibility randomised controlled trial…

2023

Abstract Background Many people do not regularly participate in physical activity, which may negatively impact their health. Current physical activity guidelines are focused on promoting weekly accumulation of at least 150 min of moderate to vigorous intensity physical activity (MVPA). Whilst revised guidance now recognises the importance of making small changes to physical activity behaviour, guidance still focuses on adults needing to achieve at least 150 min of MVPA per week. An alternative ‘whole day’ approach that could motivate the public to be more physically active, is a concept called Snacktivity™. Instead of focusing on achieving 150 min per week of physical activity, for example …

Being active in pregnancy : Theory-based factors associated with physical activity among pregnant women

2019

Although regular physical activity is recommended for pregnant women, compared to pre-pregnancy, antenatal physical activity often reduces or ceases completely. Drawing from the theory of planned behavior, self-determination theory, and theory on self-control, we aimed to test an integrative model of physical activity in a sample of pregnant women. The current study was conducted in Brisbane, Australia, in 2014–2015 using a prospective-correlational design with a one-week follow-up. Participants (N = 207, Time 1; Meanage = 30.03 years, SDage = 4.49 years) completed an initial survey measuring: intrinsic motivation from the self-determination theory, social cognitive constructs from the theo…

Application of the trans-contextual model to predict change in leisure time physical activity

2021

Objective: This study tested effects of changes in the psychological constructs of the trans-contextual model (TCM) on changes in adolescents' outside of school moderate-to-vigorous physical activity (PA) measured using self-report and accelerometer-based device. Design: A three-wave longitudinal design was used. High school students (N = 331) completed measures of all the TCM constructs at Time1 and at Time2, five weeks apart. Self-reported PA behaviour was measured also at Time3, five weeks after Time2. PA was measured using accelerometer-based devices for seven days following Time1 and Time3 for a census week. Results: A structural equation model using residual change scores revealed tha…

Student intention to engage in leisure-time physical activity: The interplay of task-involving climate, competence need satisfaction and psychobiosoc…

2018

Grounded in achievement goal theory and basic psychological needs theory, the aim of this study was to examine the impact of the interaction of perceived motivational climate in physical education with psychological needs satisfaction (relatedness, competence and autonomy) and psychobiosocial states on student intention to engage in leisure-time physical activity. Participants ( N = 470 Italian students, 287 boys and 183 girls, aged 16–19 years) completed the Teacher-Initiated Motivational Climate in Physical Education Questionnaire, the Psychological Needs Satisfaction Scale in Physical Education, the Psychobiosocial States Questionnaire, and a measure of intention to engage in leisure-tim…
