Abstract
In Canada, approximately 28% of 12 to 14 year old children and 66% of 15 to
19 year olds are deemed to be physically inactive (Statistics Canada, 1998).
Increasing the opportunities children have to be active may be an effective
strategy in increasing the activity levels of children. School-based intervention
strategies are an excellent way to target the physical activity as they can reach
almost all children and have been shown to be effective in increasing their
physical activity levels. The school-based intervention used in this study (In Motion) was a physical activity intervention that offered 30 minutes of physical
activity to every student on every school day. PURPOSE: To evaluate the effectiveness of an intervention strategy at increasing the activity levels of
grade 4 and 5 children. METHODS: Participants were recruited from two Saskatoon elementary schools, which involved five classes of participants from
the In Motion School (n = 81), and two from the non-In Motion School (n = 52). The classes were compared using anthropometric measures to identify if
the groups were similar and to assess if maturity status affected physical
activity levels. To determine the physical activity levels of the children,
pedometers were worn for seven consecutive days and a seven-day recall
questionnaire (PAQ-C) was completed. Data was analyzed between the schools
using a One-way ANOV A and Post Hoc Least Square Differences. RESULTS:
At the end of the evaluation, teacher logs revealed that three In Motion classes
did not meet the 30-minute criteria. These classes were identified as noncompliant
In Motion Classes. Amongst the In Motion, non-compliant In Motion, and non-In Motion classes there were no maturational differences
noted and the PAQ-C showed no significant differences in physical activity
levels between the groups. Results from the pedometers showed between the
three classes, there were no differences in the physical activity levels of
children during school hours and outside of school hours. However, it was
found that the In Motion classes did take significantly (n < .05) more steps over
the weekend (855 ± 300), than the non-compliant In Motion classes (651 ± 314)
and the non-In Motion classes (694 ± 378). There was no relationship found
between the results of the pedometers and the PAQ-C (r = 0.22).
CONCLUSION: In Motion is an example of an intervention strategy that
helped children to obtain 30 minutes of physical activity per day. When this
program was adhered to in its entirety, children also exhibited increased
physical activity levels on the weekend.
