We conducted preliminary studies testing the relevance of a new construct for understanding women's uninvolvement in regular physical activity: negative selfperception due to past PA experiences (NSPPPAE). In study 1, we tested the clarity of a three-item scale and computed principal component analysis, standardized Cronbach's alpha coefficients, and test-retest reliability using Pearson's correlation coefficient. In study 2, we performed principal component analysis, Pearson's correlation tests, and multiple regression analysis to determine (1) NSPPPAE's association with variables related to PA involvement and (2) NSPPPAE's power to predict time spent in vigorous or moderate recreational activity. The scale showed satisfactory internal consistency and good test-retest reliability. NSPPPAE was positively associated with time barrier (r = .31), tiredness barrier (r = .52), age (r = .15), and BMI (r = .28), and negatively associated with time in recreational activity (r = −.36). It significantly predicted (β = −.20, p = .003) time in recreational activity. This construct provides deeper insight into women's uninvolvement in regular PA.

PHYSIQUE III N°3 (it) flow separation, deposition site for conveyed particle deposition at the vessel wall, can be observed in the 70 degrees bifurcation only However, our techniques have current limitations: (i) a spatial averaging of the velocity measurements in the excited slice thickness, over which the velocity field varies, and (ii) the inability to synchronize the velocity component measurements between the various modes of operation.1.

Physical activity (PA) and limiting sedentary behavior have been recognized as health-promoting behaviors for many years. Since the COVID-19 pandemic, changes in lifestyle habits have occurred, causing disparities in PA practice. This article aimed to examine the characteristics of French adults who self-reported having difficulties in continuing their exercise practices during the pandemic. Multivariate logistic regressions were used to test whether certain demographic, morphologic, behavioral (sleep, sedentary lifestyle, extent of household chores), and exercise-related variables were significant predictors of experiencing such difficulties, based on data from an online survey of insurance company members. Difficulties in PA practice were found in 57% of the population surveyed. Several factors were identified as predictors of experiencing difficulties, including a high BMI, the type and number of physical activities usually practiced before lockdown, as well as the number of times per week dedicated to PA. For the employed population, specific factors were additionally decisive: sex, time spent in front of screens, and sleeping. Our results will allow public health policy makers and stakeholders in PA and prevention to better target populations in difficulty during periods of disruption, such as that of the pandemic; thus, allowing them to propose structural or organizational solutions for the continuity of PA practice.
