Experiences of students with HIV/AIDS in rural, post-conflict Uganda

2015

The roll out of Anti-Retroviral Therapy across Sub-Saharan Africa has given rise to a new generation of adolescents that previously would not have survived into their teen years. The aim of this research is to give voice to these young people, specifically HIV positive students, in the rural, post-conflict area of Katakwi, Uganda. Through the lens of empowerment, which focuses on participation, capacity building, leadership potential, and relationships, this research examines the factors in these students’ lives that contribute to their empowerment, or the absence of these factors that then have the potential to disempower them. It considers the way the students themselves see both the prot…

Toward adjustment profiles for lower secondary student-athletes in the Finnish dual career context: A mixed-methods approach

2022

Engagement, burnout, and experiences are central concepts for understanding student-athlete adjustment in a dual career (DC) environment. As part of a larger 3-year, lower secondary sports schools pilot project, the aim of this study was to examine student-athletes’ DC adjustment in Finnish lower secondary sports schools at the end of the second academic year. By combining quantitative and qualitative methods, we sought to (a) identify adjustment profiles among student-athletes based on measures of engagement and burnout in school and sport and (b) to extract experiences that describe the distribution of student-athletes in the profiles. A latent profile analysis using questionnaire data fr…

Effect of fall direction on the lower hip fracture risk in athletes with different loading histories : A finite element modeling study in multiple si…

2022

Physical loading makes bones stronger through structural adaptation. Finding effective modes of exercise to improve proximal femur strength has the potential to decrease hip fracture risk. Previous proximal femur finite element (FE) modeling studies have indicated that the loading history comprising impact exercises is associated with substantially higher fracture load. However, those results were limited only to one specified fall direction. It remains thus unclear whether exercise-induced higher fracture load depends on the fall direction. To address this, using magnetic resonance images of proximal femora from 91 female athletes (mean age 24.7 years with >8 years competitive career) and …

Association between long-term exercise loading and lumbar spine trabecular bone score (TBS) in different exercise loading groups

2015

Objective: To examine whether different exercise loading is associated with lumbar vertebral texture as assessed with Trabecular Bone Score (TBS). Methods: Data from 88 Finnish female athletes and 19 habitually active women (reference group) were analyzed. Participants’mean age was 24.3 years(range 17-40 years).Athletes were divided into five specific exercise loading groups according to sport-specific training history: high-impact (triple jumpers and high jumpers), odd-impact (soccer players and squash players), high-magnitude (power lifters), repetitive impact (endurance runners), and repetitive non-impact (swimmers). TBS-values were determined from lumbar vertebral L1-L4 DXA images. Body…

Social Environmental Antecedents of Athletes’ Emotions

2021

The coach-created motivational climate influences variations in athletes’ motivation and emotional experiences. The present study aimed to examine social environmental antecedents of athletes’ emotions. Participants (N = 262, 52% female, M age = 22.75 ± 6.92) completed questionnaires assessing perceptions of coach-created motivational climates, goal orientations, motivation regulations, and emotions. The mediation effects of goal orientations (i.e., task/ego) and motivation regulations (i.e., autonomous/controlled) on the relationship between motivational climate (i.e., empowering/disempowering) and emotions (i.e., happiness, excitement, anxiety, dejection, and anger) were examined. Structu…
