Time Motion app for Ipad2

Today in my 8/9 PE class I used the Time Motion app to collect data on student movement during their volleyball games. The time motion app allows you to record (for a single student) the % of time spent standing, walking, jogging, fast running and sprinting. Normally you get the data and then email it but as there is no WiFi in our gym I copied the data from the Ipad2 against the students name on a piece of paper which was fairly painless. Each student that I observed was watched for 2 minutes. It then took ten minutes to enter that data on a spreadsheet and produce a graph that showed my classes movement intensities. Today was just an experiment but in the future this data will be excellent for students to analyse and make links between those who are successfull in games/sports and the amount of effort (movement) they put in while older students can look at which energy systems are dominant during a particular sport based on movement intensity. Such a simple app providing powerful data!
