Long‐term effects of basic coach education on ice hockey coaches' beliefs and use of need‐supportive behaviors
The long‐term impact of education on sport coaches' interpersonal behaviors remains unclear. In this longitudinal study ( N = 52) we examined one‐year changes in ice hockey coaches' use of need‐supportive behaviors following a two‐day basic coach education both shortly after the intervention and one year later. Coaches reported effectiveness, easy‐to‐implement, and normative beliefs about need support and their use of autonomy, competence, and re…
Students’ perception of dominant objectives in Physical Education
Background Possible PE discourses and possible outcomes of such discourses are frequently debated in PE research. According to the literature instrumental and performance discourses, as well as more holistic, developmental discourses exist but there is reason to question how far into the PE teaching and thus PE students’ learning processes these discourses reach. At present, we do not know to what extent discourses identified in the discursive cl…
Barriers and enablers of a formal coach development program
Background Formal coach development programs (CDPs) are central to national sports accreditation systems, yet little is known about the implementation fidelity of introductory, policy-based coaching courses. Although such programs follow standardized curricula, variations in delivery and reception are common, shaped by educators’ interpretations, differing levels of implementation preparedness, logistical constraints, and the diverse backgrounds …
Development of brief assessment packages of psychosocial constructs related to doping
Background We aimed to develop brief self-report tools that can be used by anti-doping organizations (ADOs) to evaluate education programs regarding their effects on psychosocial correlates of doping. Current assessment tools are too long for this purpose.Methods In phase 1, we reviewed the literature and selected psychosocial constructs perceived to be amenable to anti-doping education. In phase 2, a survey with these constructs was sent to anti…

Female athletes' knowledge of biopsychosocial puberty-related topics in sports. What is missing
Introduction Puberty has been identified as one of the main contributing factors for girls dropping out of sports during adolescence. Knowledge and social support can, however, help athletes navigate the biopsychosocial (BPS) puberty-related changes associated with this period. Yet, research on female athletes' knowledge about BPS puberty-related topics is lacking. Therefore, this cross-sectional study aimed to examine female athletes' perceived …
Assessing the individual relationships between physical test improvements and external load match parameters in male professional football players—a brief report
Purpose This study aimed to explore whether a meaningful improvement in physical performance following an in-season strength training intervention can be related to external load match parameters at an individual level in professional male football players. Methods Eight male professional football players (25.4 ± 3.1 years, 184.1 ± 3.4 cm, 79.3 ± 2.2 kg) completed a 10-week strength intervention period in addition to football-specific training an…
Short-term effects and long-term changes of Fuel-a digital sports nutrition intervention on REDs related symptoms in female athletes
Female endurance athletes are at high risk for developing Relative Energy Deficiency in Sport (REDs), resulting in symptoms such as menstrual dysfunction and gastrointestinal (GI) problems. The primary aim of this study was to investigate effects of the FUEL (Food and nUtrition for Endurance athletes-a Learning program) intervention consisting of weekly online lectures combined with individual athlete-centered nutrition counseling every other wee…
Favorable Adaptation during Sars-CoV-2-Pandemic as Told by Student-Athletes—A Longitudinal and Behavioral Study
(1) Background: The aim was to explore the impact of adaptive responses (resilience factors) on student-athletes' behaviors during a stressful period of life during the SARS-CoV-2-pandemic of 2020 and 2021. (2) Methods: A constructivist-based grounded theory (CGT) was used guided by a biopsychosocial approach. Based on purposeful sampling, 22 male and female student-athletes were divided into four focus group interviews (FGI) seven months after t…
Psychosocial Predictors of Drop-Out from Organised Sport
In recent years an increased drop-out rate in adolescents' soccer participation has been observed. Given the potentially adverse consequences of drop-out from soccer, more information about risk factors for drop-out is warranted. In the current study, Classification and Regression Tree (CRT) analysis was used to investigate demographic and motivational factors associated with an increased risk of drop-out from adolescent soccer. The results of th…
Empowerment-Based Physical Activity Intervention for People with Advanced Dry Age-Related Macular Degeneration
Age-related macular degeneration (AMD) is the most common cause of incurable visual impairment and impacts daily life. These impacts include loss of social activities, decreased functional independence, and reduced physical activity. This protocol aims to describe a prospective, mixed-methodology for studying a population with AMD before, during, and after an empowerment-based physical activity intervention (EPI). A study framework was also devel…
Simulated Game-Based Ice Hockey Match Design (Scrimmage) Elicits Greater Intensity in External Load Parameters Compared With Official Matches
Objective A limited number of studies have explored the external load experienced in indoor sports such as ice hockey, and few the link between training and match performance. As a paucity exists within this topic, this study explored whether a simulated match design (i.e., scrimmage) could be representative of official match demands and elicit similar external loads as in official matches in a group of elite youth male ice hockey players. Method…
Associations between physical activity and core affects within and across days
OBJECTIVE: The objective of the present study was to investigate (a) if daily physical activity at the within-person level is related to four different core affects the same evening, (b) if core affects in the evening predict physical activity the following day, and (c) if physical activity predicts core affects the following day. DESIGN: A total of 166 university students were asked to complete the affect and physical activity measures once a da…
The Role of the Results of Functional Tests and Psychological Factors on Prediction of Injuries in Adolescent Female Football Players
Football is a popular sport among adolescent females. Given the rate of injuries in female footballers, identifying factors that can predict injuries are important. These injuries are often caused by complex reasons. The aim of this study was to investigate if the combination of demographic (age, number of training and match play hours/week), psychosocial (perceived stress, adaptive coping strategies) and physiological factors (functional perform…
Is Perceived Autonomy Support Provided by a Coach Related to the Intention of Injury Preventative Behavior Among National and International Level Golfers
The successful implementation of injury prevention programs is reliant on athletes and coaches accepting, adopting, and complying with behaviors that reduce injury risk. Exploring factors, such as motivation and planned behavior, that might increase the frequency of these behaviors warrants investigation. The aim of the study was to investigate the complex interaction between perceived autonomy support, self-determined motivation, planned behavio…
The role of domain-specific and domain-general cognitive functions and skills in sports performance
