- Abstract
- School settings are an essential source of physical activity for adolescents because they provide curricular, co-curricular opportunities in addition to time during scheduled breaks. There has been limited previous research examining the physical activity behaviour of adolescents during break periods. Purpose: The aim of this study was to investigate the inter-day variability of adolescent's physical activity (PA) during school lunchtime periods. Methods: Participants (n = 40) from yr 8 to 10 (mean age = 14.5 ± 0.8 yrs) wore a SPI-Elite Global Positioning System (GPS) unit during five lunchtimes during a school week. Heart rate (HR), speed, distance, global position, and G force were measured for each participant and reported across a range of play spaces including a cricket net area, grassed oval, quadrangle, basketball/netball court area and seated shaded area for each participant across the five days. Analyses were performed on time periods randomly selected from three days for windows of 20 min+. Time spent within the various play spaces was determined by overlaying GPS data with Google Earth images of the school playground. Results: Independent samples t-tests revealed males (mean = 2.5 ± .97 km) covered a greater distance compared to females (mean = 1.5 ± .73 km) at the p < 0.01 level. Males also displayed significantly higher HR than did females during lunch breaks, at the p < 0.01 level. Students spent significantly more time and covered the greatest distance on the oval (grassed area) when compared to other play spaces (p < 0.01), and girls spent significantly more time in the seated shaded area than did males (p < 0.01). There were no significant differences for inter-day variability of average time, distance, HR, speed or G force within adolescent students’ physical activity during lunchtimes. Conclusions: The results suggest adolescents’ physical activity during lunch breaks is relatively stable across days. There are a number of feasibility issues relating to the use of GPS technology within the context of school settings and these are discussed. Future physical activity interventions targeting adolescents should consider the nature of the play space and may need to be tailored differently for males and females.
