\section{Results}

To complete all four missions, the children spent approximately 3,290 minutes (equivalent to 55 hours). They were able to take 159,549 steps during this period of time.

For Mission 1, the teacher recorded the time (in seconds) required for each team to complete the assault course using a stopwatch, as shown in Figure \ref{fig:mission1}. As the Fitbit for the yellow team was malfunctioning on the Tuesday, they did not compete that day. Figure \ref{fig:fit1} shows the amount of physical activity performed (in minutes) by each team for each day of the week, where the stacked bar is showing the level of physical activity. The number of steps recorded by the Fitbit is also plotted on the same graph, and can be read on the second y-axis to the right of the graph.

In Figure \ref{fig:mission2} the time to find the token for Mission 2 (in minutes) is shown for each team. On the Monday the silver team spent a large amount of time (23:10) compared to other days in order to find the token. As such the data point was shortened to make the graph more readable. The data recorded by the Fitbit is shown in Figure \ref{fig:fit2}.

The number of points scored during Mission 3, recorded by the teacher and grouped by team, is shown in Figure \ref{fig:mission3}. The related Fitbit data is shown in Figure \ref{fig:fit3}. Figure \ref{fig:mission4} shows the time taken (in seconds) for each team to complete Mission 4, as recorded by the teacher using a stopwatch. The Fitbit data for Mission 4 is shown in Figure \ref{fig:fit4}.


Overall, there were no significant differences in any physical self-perceptions over time (P>0.05). Results are shown in Table \ref{tab:psppc}.
