Evaluation of an unstructured after school physical activity program for disadvantaged youth
- Published on Mar 23, 2016
The purpose of the study was to conduct an evaluation of an unstructured afterschool physical activity (PA) programme (Keep it Moving!; KIM) in an ethnically diverse and low socio-economic status (SES) school district. PA of students in 3rd–5th grades (N = 205) at four elementary schools were assessed during spring 2012. An ActiGraph accelerometer was utilised to examine objectively measured time and steps in differing intensity levels. Standard data reduction procedures were used to process collected data and characterise PA. Students averaged approximately 54 min of accelerometer wear-time during the KIM programme, 10.4 ± 6.1 min (19.2%) of which were spent in sedentary behaviour, 28.2 ± 8.3 min (52.1%) in light PA and 15.6 ± 6.6 min (28.7%) in moderate-to-vigorous intensity PA. Within the cadence band of 1–19 steps/min participants accumulated the highest time-derived PA (16.4 ± 6.3 min). In total, children averaged 1811.9 ± 527.5 steps during the entire KIM programme. Results from the programme indicated that elementary-aged students received additional PA through the KIM programme. The mean value of accumulated steps during the afterschool PA programme represented 12–16.5% of the minimum steps/day target (depending upon gender) identified for elementary-aged school children. These data represent unique findings from a high-need population that may be helpful for researchers and practitioners alike.
