• Promoting health benefits is necessary but insufficient to foster sustained engagement in physical activity (PA). • Our formal decision-making model explains why health benefits hold a weak subjective value. • In this model, expected health benefits are jointly discounted by effort-discounting, delay-discounting, and beliefs distortion. • In contrast, positive affective experiences toward PA can reduce the perception of effort, provide more immediate consequences, and strengthen beliefs about health benefits. • Because affective experiences have the potential to tip the balance in favor of PA over sedentary alternatives, they should be at the core of PA promotion.

Despite the well-established benefits of regular physical activity (PA) on health, a large proportion of the world population does not achieve the recommended level of regular PA. Although affective experiences toward PA may play a key role to foster a sustained engagement in PA, they have been largely overlooked and crudely measured in the existing studies. To address this shortcoming, the Affective Exercise Experiences (AFFEXX) questionnaire has been developed to measure such experiences. Specifically, this questionnaire was developped to assess the following three domains: antecedent appraisals (e.g., liking vs. disliking exercise in groups), core affective exercise experiences (i.e., pleasure vs. displeasure, energy vs. tiredness, and calmness vs. tension), and exercise motivation (i.e., attraction vs. antipathy toward exercise). The current study aimed to validate a Chinese version of the AFFEXX questionnaire (AFFEXX-C). In study 1, 722 Chinese college students provided data for analyses of factorial, convergent, discriminant, criterion validity, and test-retest reliability of the AFFEXX-C. In addition, 1,300 college students were recruited in study 2 to further validate its structural model. Results showed that the AFFEXX-C demonstrates a good fit and reliability. Additionally, results further supported the hypothesized model based on previous research: antecedent appraisals predicted core affective exercise experiences, which in turn predicted attraction-antipathy toward physical exercise. The AFFEXX-C was found to be a reliable and valid measure of affective exercise experiences in a population of Chinese college students. [ABSTRACT FROM AUTHOR]

The article focuses on the challenges of promoting regular physical activity despite its well-established health benefits. It highlights three key factors that hinder behavior change such as the high effort required over a lifetime for health benefits; the delayed and intangible nature of these benefits; and cognitive biases that lead to undervaluing physical activity. It suggests that emphasizing the pleasure derived from physical activity could be a more effective.

To assess whether changes in physical activity and sedentary behaviour during the COVID-19 lockdown are associated with changes in mental and physical health. Observational longitudinal study. Participants living in France or Switzerland responded to online questionnaires measuring physical activity, physical and mental health, anxiety, and depressive symptoms. Paired sample t-tests were used to assess differences in physical activity and sedentary behaviour before and during lockdown. Multiple linear regressions were used to investigate associations between changes in physical activity and changes in mental and physical health during lockdown. 267 (wave1) and 110 participants (wave2; 2 weeks later) were recruited. Lockdown resulted in higher time spent in walking and moderate physical activity (~10min/day) and in sedentary behaviour (~75min/day), compared to pre COVID-19. Increased physical activity during leisure time from week 2 to week 4 of lockdown was associated with improved physical health (β=.24, p=.002). Additionally, an increase in sedentary behaviour during leisure time was associated with poorer physical health (β=−.35, p=.002), mental health (β=−.25, p=.003), and subjective vitality (β=−.30, p=.004). Ensuring sufficient levels of physical activity and reducing sedentary time can play a vital role in helping people to cope with a major stressful event, such as the COVID-19 pandemic.
