Affective experiences from exercise. Youth-adult differences and prediction of exercise behavior.

Affective exercise experiences are summative, valenced memories that represent the history of associations between past instances of exercise in an individual's life and pleasant or unpleasant reactions. We used the recently developed Affective Exercise Experiences (AFFEXX) questionnaire to address two important questions in exercise psychology, namely the nature of affective exercise experiences during the childhood-adulthood transition and the relationship between affect and exercise behavior. The first study compared data from 949 adults and 607 children and adolescents, and showed that core affective exercise experiences were associated with different antecedent appraisals in the two groups.

[Physical Activity-Related Health Services in Germany: Relevance and Necessary Framework Conditions - a Position Paper of the DNVF Working Group Physical Activity-Related Health Services Research].

Based on the relevance of an established and broad foundation of physical activity in healthcare, this position paper of the DNVF working group Physical Activity-Related Health Services research presents current conceptual approaches to physical activity-related health services in Germany and highlights the need for interprofessional and interdisciplinary approaches. Three central positions are outlined and elaborated in order to integrate the evidence on health benefits of physical activity and exercise more strongly into healthcare and to show that, against the background of the challenges in the German healthcare system, physical activity-related health services can make a cost-effective and high-quality contribution to improve healthcare. These three positions include 1) the integration of all professional groups involved in healthcare into physical activity-related health services, 2) the greater integration of physical activity professions and physical activity interventions into all healthcare contexts and 3) the systematic consideration of physical activity- and exercise-related expertise in clinical guidelines.

Exploring person-specific associations of situational motivation and readiness with leisure-time physical activity effort and experience.

Identifying determinants of leisure-time physical activity (LTPA) often relies on population-level (nomothetic) averages, potentially overlooking person-specific (idiographic) associations. This study uses an idiographic perspective to explore how subjective readiness and motives for LTPA relate to volitional effort (duration, intensity) and affective experience (pleasure, displeasure). We also highlight the potential for different interpretations when data are averaged within individuals and assessed using a variable-centered approach.
