摘要：The Active Snacks project (2019/2020) is aimed both at studying the motor development of the child andopening new opportunities for the practice of physical activity in primary and secondary schools. The purpose of this study is to evaluate the effects of active breaks on enjoyment and perceived self-efficacy,showing preliminary results of the project. The sample is made up of 56 primary and secondary school children (M = 31,F = 25,age = 9.64 ± 1.40,weight = 41.80 ± 23.3 kg,height = 1.42 ± 0.10 m,BMI = 20.26 ± 4.09 kg / m2) from an Apulian province. The intervention protocol provided for the proposal of 3-5-minute active breaks,carried out in the classroom for a week during school hours. Psychological factors were assessed with two self-reports: PSP_C and PACES. Besides descriptive statistics (M ± SD),the analysis of ANOVA and Pearson’s correlation coefficient were performed to measure pre-and post-intervention differences relatedto BMI. The significance index was set at p <.05. The results highlighted: (a) overweight children achieved higher scores in terms of perceived selfefficacy and enjoyment than those of normal weight and obese,both in pre- and post-intervention;(b) statistically significant differences in the level of self-efficacy (Nw vs Ob;Ow vs Ob) post intervention;(c) moderate to high correlations between BMI and perceived self-efficacy post intervention in overweight and obese groups. Preliminary results proved useful and effective for increasing levels of self-efficacy and fun in normal weight groups. Further studies are needed to evaluate the effects in the medium to long term.
