Abstract:
Purpose: The majority of German youth do not meet the national recommendation of 90 minutes of daily moderate-to-vigorous physical activity (MVPA). With growing age, adolescents engage less in physical activity (PA) with the decrease being even more severe in girls compared to boys (Finger, Varnaccia, Borrmann, Lange, & Mensink, 2018). Aim of the CReActivity-project is to promote PA of sixth grade girls by supporting the basic psychological needs autonomy, competence and relatedness in physical education (PE) and to identify mediating and moderating constructs of physical activity behaviour change. Purpose of the poster is to present analysis of objectively measured PA and its results. Methods: In the longitudinal randomized controlled trial participating classes were randomized on schoollevel to control and intervention group. At baseline 622 children (aged 11 to 12 years) wore accelerometers on their right hip (ActiGraph models GT3X, wGT3X-BT; Pensacola, FL, USA) for at least six consecutive days and answered a nine-scale questionnaire assessing basic psychological needs support and satisfaction in PE and leisure time, self-efficacy, social support, intrinsic motivation and environmental factors. During the 16-week intervention period, trained teachers carried out the intervention programme. It was evaluated by systematic observations of PE lessons with a modified SOFIT protocol and interviews with teachers and focus groups. The analysis of PA included baseline data from three survey periods between early 2016 and late 2018, if data had at least three valid weekdays and one valid weekend day with a minimum of eight hours wear time (n = 482). Findings: MVPA was higher on weekdays compared to weekend days. 90.87% of the participants reached the WHO recommendation of 60 minutes of MVPA during weekdays but only 60.17% for an average weekend day. 42.95 % reached 90 minutes of MVPA on weekdays, while 21.58% fulfilled the German MVPA recommendation on weekend days. MVPA on weekdays was significantly higher compared to weekend days (z = -13.47, p < .001). Conclusions: Further statistical analysis and consideration of theoretical foundations, mediating constructs and moderating variables, will provide a direct link between intervention components and changes in physical activity behaviour.
