Krievijas 2014-2019.gada protekcionisma politikas ietekme uz Latvijas ekonomiku
2021
Sākot ar 19-to gadsimtu, kad Adama Smita darbi un uzskati guva izteikto popularitāti politiķu un zinātnieku lokā, brīvā tirgus ekonomika tika uzskatīta par pareizo ārējās tirdzniecības politikas veidu un valsts valdības iejaukšanās tirdzniecībā tika sistemātiski kritizēta. Tas rada izteiktas pretrunas starp ekonomistu un zinātnieku viedokļiem, pirmie aktīvi piemin vairākas brīvās tirdzniecības priekšrocības un uzskata, ka tirdzniecības liberalizācija palīdz likvidēt nabadzību, tajā pat laikā otri - filozofi – ir pārņemti ar domām par brīvās tirdzniecības sistēmas nevienlīdzību pret valstīm ar dažādu ekonomisko attīstības līmeni un iesaka izmantot protekcionisma principus, lai mazināt nabadz…
Modification and Applicability of Questionnaires to Assess the Recovery-Stress State Among Adolescent and Child Athletes
2019
Despite the general consensus regarding the implementation of self-report measures in the training monitoring, there is a lack of research about their applicability and comprehensibility among developing athletes. However, this target group needs special considerations to manage the increasing training demands while maintaining health and performance. This study deals with challenges of applying recovery-stress questionnaires which were validated with adult populations among developing athletes and presents a possible approach to enhance their applicability. In two phases, the Acute Recovery and Stress Scale (ARSS), a 32-adjective list covering eight scales, and the 8-item derived version, …
Career Adapt-Abilities Scale – Dual Career Form (CAAS-DC): psychometric properties and initial validation in high-school student-athletes
2016
Talented adolescent athletes attempting to sustain academic and vocational training alongside the increasing demands of their athletic career often encounter difficulties, including lower vocational readiness and the challenge of adapting to life after elite sport. Therefore, it is necessary to better understand the specific competencies that youth athletes can draw upon to successfully combine sport and education into a dual career pathway. Building on the existing Career Adapt-Abilities Scale [Savickas & Porfeli, (2012). Career adapt-abilities scale: Construction, reliability, and measurement equivalence across 13 countries. Journal of Vocational Behavior, 80(3), 661–673], we developed a …
Psychometric Evaluation of the Norwegian Versions of the Modified Group Environment Questionnaire and the Youth Sport Environment Questionnaire
2021
This study aimed to translate the modified Group Environment Questionnaire (GEQ) and the Youth Sport Environment Questionnaire (YSEQ) into Norwegian, examine the factor structure and reliability of the scales through independent clusters model confirmatory factor analysis (ICM-CFA) and exploratory structural equation modeling (ESEM), and examine differential item functioning (DIF) as a function of sex. Three-hundred-and-thirty-three athletes (M(SD)age = 18.7(2.60) years; 33% females) completed the GEQ. Three-hundred-and-three athletes (M(SD)age = 15.0(1.48) years; 26% females) completed the YSEQ. Results indicated acceptable fit indices for a four-factor, a second-order two-factor (task a…
Mental Health in Athletes: Where Are the Treatment Studies?
2022
In recent years, athletes’ mental health has gained interest among researchers, sport practitioners, and the media. However, the field of sport psychology lacks empirical evidence on the effectiveness of psychotherapeutic interventions for mental health problems and disorders in athletes. Thus far, intervention research in sport psychology has mainly focused on performance enhancement using between-subject designs and healthy athlete samples. In the current paper, we highlight three interrelated key issues in relation to treating mental health problems and disorders in athletes. (i) How are mental health and mental health problems and disorders defined in the sport psychology literature? (i…

Effects of training on bone metabolism in young athletes
2021
Purpose. This study investigated the effects of two types of training on the bone formation marker of osteocalcin and the bone resorption marker of tartrate-resistant acid phosphatase isoenzyme 5b (TRAP5b) in young track and field boys and girls. Methods. The 14-year-old group (10 boys, 10 girls) performed first time an intensive and supervised 8-week plyometric training. In the 17-year-old group (13 athletic boys, 6 control boys, 12 athletic girls, 6 control girls), the normal many-sided track and field training lasted 6 months. Results. Significant increases were noticed in osteocalcin (p < 0.01) both in younger boys and girls. The 20-m sprint performance improved in girls (p < 0.01) and …
Dementia in former amateur and professional contact sports participants : population-based cohort study, systematic review, and meta-analysis
2023
Background Although there is growing evidence that former professional athletes from sports characterised by repetitive head impact subsequently experience an elevated risk of dementia, the occurrence of this disorder in retired amateurs, who represent a larger population, is uncertain. The present meta-analysis integrates new results from individual-participant analyses of a cohort study of former amateur contact sports participants into a systematic review of existing studies of retired professionals and amateurs. Methods The cohort study comprised 2005 male retired amateur athletes who had competed internationally for Finland (1920–1965) and a general population comparison group of 1386 …
