Relationship between physical activity and predicted home presenteeism among participants with depressive symptoms with and without clinical depressi…
2021
Background and objectives Depression can pose a major threat to an individual’s ability to cope with daily activities. The aim of this study was to explore the relationship between physical activity (PA) and predicted home presenteeism (PHP) among depressive participants. The relationship between PHP and the severity of depressive symptoms was also investigated. Methods A total of 760 participants with depressive symptoms (DS) aged ≥35 years participated in this study. The study was conducted between 2008 and 2016 in municipalities within the Central Finland Hospital District. DS were determined with the 21-item Beck Depression Inventory (BDI-21) with a cutoff score ≥10, and psychiatric dia…

Effects of the Extraction Technology on Pomegranate Juice Quality
2020
Pomegranate juice is a rich source of phenolic components; its consumption has considerably increased throughout the world in recent years, due to its nutraceutical properties. Commercial juice production involves pressing the fruits. The aim of this study was to assess the influence of the pressing stage on pomegranate juice properties, in terms of value, duration of the applied pressure and juice yield in order to examine the influence of pressure level on volatiles and nutraceutical properties of the juice. Pomegranate fruits cv. Wonderful One were manually harvested and mechanically processed for extracting the juice by means of a shelling machine, a peristaltic pump and a pneumatic pre…

Introduction Adolescents’ physical activity (PA) behavior can be driven by several psychosocial determinants at the same time. Most analyses use a variable-based approach that examines relations between PA-related determinants and PA behavior on the between-person level. Using this approach, possible coexistences of different psychosocial determinants within one person cannot be examined. Therefore, by applying a person-oriented approach, this study examined a) which profiles regarding PA-related psychosocial variables typically occur in female sixth-graders, b) if these profiles deliver a self-consistent picture according to theoretical assumptions, and c) if the profiles contribute to the…
Sport participation and vigilance in children: Influence of different sport expertise
2018
PURPOSE: The present study aimed to investigate the relationship between different types of sport expertise (externally-paced vs. self-paced sports) and vigilance performance in children by evaluating the cardiovascular fitness level of the participants. METHODS: Three groups of children (11.0 ± 0.2 years) differentiated in terms of their regular sport participation (football players, n = 20; track and field athletes, n = 20; non-athletic controls, n = 20) took part in the study. In one session, participants performed the Leger Multi-stage fitness test to estimate their aerobic fitness level. In another session, participants completed the Psychomotor Vigilance Task (PVT) to evaluate their v…
El ejercicio físico y la promoción de la salud en la infancia y la juventud
1992
SummaryThe «new health consciousness» that emerged in the developing countries in the 70s and 80s, has contributed to consider exercise as an element of health promotion. But it can establish simplistic relationships between exercise and health, particularly critical for professionals who develop promotion programmes. In this paper, five problematic aspects linked, to exercise and health relationships both in children and youngsters, are discussed and should be taken into account when promoting health programmes. We refer to: 1) the problematic role of exercise in health promotion and in physical education curriculum as an area of privileged action in children and youngsters; 2) the automat…
Human Sensorimotor Communication: A Theory of Signaling in Online Social Interactions
2013
Although the importance of communication is recognized in several disciplines, it is rarely studied in the context of online social interactions and joint actions. During online joint actions, language and gesture are often insufficient and humans typically use non-verbal, sensorimotor forms of communication to send coordination signals. For example, when playing volleyball, an athlete can exaggerate her movements to signal her intentions to her teammates (say, a pass to the right) or to feint an adversary. Similarly, a person who is transporting a table together with a co-actor can push the table in a certain direction to signal where and when he intends to place it. Other examples of ``si…
Brain representation of action observation in human infants.
2015
Imitative learning has long been established as extremely important for early development. However, neural mechanisms involved in early imitative behaviours are still areas of active research. Neurophysiological and brain-imaging studies have been recently performed that provide initial evidence of brain activation associated with action observation in the first months of life. In this review we examine all studies exploring the effects of action observation on brain function assessed by means of non-invasive brain-mapping techniques. Seventeen papers were selected as a result of our literature search. The strongest evidence for a neural signature of action observation comes from studies ex…
THE DEVELOPMENT OF ART EDUCATION IN LATVIA FROM 1890 TILL 1990
2012
Art education is a very important field, as it represents the ethical and esthetical needs of the society and reflects the politics and ideology of the age. The urgency of art education and cultural education is affirmed also by the fact that the year 2009 was announced as the year of innovations and creativity in Europe. It is necessary to research the possibilities the art education can offer to promote the creativity of young people and to improve the quality of art education. The overview of the history of art education gives us the possibility to find connections between different conditions as well as examples of the best practice. The development of art education is divided into thre…
Happiness in Physical Activity: A Longitudinal Examination of Children Motivation and Negative Affect in Physical Activity
2020
Physical activity has beneficial effects on health and is extremely recommended for children's well-being. Understanding risk factors that could cause negative affect in children practicing physical activity is hugely relevant, and there is a growing consensus that autonomous and controlled motivation in the self-determination theory (SDT) framework could offer a broader perspective. Consequently, this study aims to examine the longitudinal relations between autonomous motivation, controlled motivation, and negative affect in physical activity, using a sample of children that regularly participate in physical activity. One hundred forty children in the range age between 7 and 11 (M = 8.45, …
