Background Physical activity (PA) is a proven therapeutic tool to increase the quality of life and life expectancy in people with cystic fibrosis (pwCF). Despite this, the PA level of pwCF is lower than recommended. Objectives This study was conducted to identify the barriers to and facilitators of PA in adults with CF with heterogeneous severity. Methods Twenty adults with CF (mean age = 33.3±11.7 years, mean FEV1% = 50.55±20.4%) were recruited from two specialized centers and interviewed about the factors that limit and facilitate their PA. The collected data were transcribed, coded and analyzed using deductive and inductive methods. Results Barriers and facilitators were classified into physical, psychological and environmental dimensions. The main barriers were fatigue, breathing difficulties, lack of available facilities, negative perceptions of PA and perceived health risks. The most important facilitators were respiratory benefits, well-being, and social support. Conclusion Although some barriers and facilitators were similar to those found in children with CF or adults from other vulnerable populations, others were specific to adults with CF, such as the risk of cross-contamination and transplant preparation. The comprehensive study of the barriers and facilitators in adults will enhance PA counseling for pwCF and help improve their compliance with PA recommendations.

Thinness is a part of today's sociocultural standards of beauty and thus is implicated in body image dissatisfaction and eating disorders. In female aesthetic sports, thinness is a standard for aesthetics and performance. Measuring the internalisation of thin-ideal standards in these athletes may therefore help them to gain insight into the risks associated with body image dissatisfaction and disordered eating. This study aimed to develop and validate the Internalisation of Sociocultural and Thin-Ideal Standards in Sports (ISTISS) Scale. Four studies involving 357 female aesthetic athletes examined the exploratory factorial structure, temporal stability, and concurrent validity of the ISTISS, which gave rise to a 10-item scale with two subscales: internalisation of sociocultural standards and thin-ideal standards in sports. Internal consistencies were satisfactory and relationships with the self-regulation of eating attitude in sport were as expected. These findings provide preliminary evidence for the ap...
