A five-minutes classroom-based active break increases physical activity and energy expenditure of elementary school students

Introduction School environment is an ideal environment for introducing interventions, action programs and projects that will change the trend of physical inactivity amongst the children and the young. Although physical education and health culture classes and courses are obligatory in the majority of the world’s and Europe’s countries, they are often shortened and irregular, many participants don’t participate actively in it (Dobbins et al., 2009 ; McKenzie et al., 1995 ; Simons-Morton et al., 1994). That is why it is necessary to find new ways of promotion and encouragement of regular physical activity and its integration during the typical day at school. Methods/Methodology Sample of elementary school children (7 - 10- yrs) has been used to evaluate effects of classroom-based physical activity program on children`s in-school physical activity levels and energy expenditure during academic instruction. During intervention period, experimental classes participated in 5 minutes of physical activity at the middle of 45 min lesson imitating video animations projected on the board. Physical activity levels and energy expenditure have been assessed for two weeks by using SenseWear Armband body monitor (BodyMedia Inc., Pittsburgh, PA, USA). Results & Discussion Due to the means of the two measures of performed steps and the direction of the t-value, we can conclude that there was a statistically significant improvement in number of steps during a school day following the 5-minutes classroom-based active break from 3276, 96±747, 11 to 4392, 49±955, 02 (p < 0, 014). After 5 minutes active break participation, students have significantly increased number of made steps done during the school day (STEPS ; 3276, 96±747, 11 to 4392, 49±955, 02 ; p=0, 014). Time spent in the physical activity during the school day was also significatly increased (PA TIME) with 56, 14±43, 46min to 83, 90±43, 20min (p=0, 028), while at the same time the time spent in sedentary activity was decreased (SED ; 195, 35±46, 8min to 169, 15±56, 29min ; p=0, 028). Participation in 5 minutes active break has significatly increased time spent in physical activity of medium intensity (MPA ; 53, 51±40, 78min to 75, 37±55, 59min ; p=0, 028), high intensity (VPA ; 2, 58±3, 11 min to 5, 9±3, 02min ; p=0, 027) and extremly high intensity (VVPA ; 0, 06±0, 09 min to 1, 9±3, 28min ; p=0, 043). By increasing the time spent in physical activity, intensity shown as metabolic equivalents (MET) was also significatly increased in experimental group from 2, 28±0, 46 to 2, 63±0, 58 Energy consumption during the physical activity was significantly increased in both group of students, from 2, 67±1, 32cal/kg to 4, 74±1, 45cal/kg in control group and from 3, 72±2, 92cal/kg to 5, 93±4, 23cal/kg in experimental group. Active break during the school lesson was 5, 63±0, 38min (PA TIME) and students were in the zone of medium (MPA ; 4, 63±0, 46min) and high (VPA ; 0, 97±0, 62) intensity most of the time exercising with intensity from 4, 72±0, 43 MET. During that activity they had lost 16, 16±3, 87 of calories (PA EE) and had done 444, 59±67, 24 of steps (STEPS). Conclusion If increase in time dedicated to physical activity in school, by including pupils in physical activity in the classroom, increases the level of physical activity and energy consumption of the pupils during a day at school, such activity can contribute to decrease one of the greatest problems of today’s world with regards to health of children and the youth. Five-minute program offers teachers a ready tool to engage students and facilitate learning by integrating physical activity into academic lessons.
