It records HR once every 10 minutes for one second in activity (all day0 tracking and once every second in sports activity tracking. If you kept it running a sports activity you would be out of batteries in a few hours. Again, there is no way to convert all-day activity to a specific sports activity, it is not collecting any data just the HR once every 10 minutes. If you go tot he progress tab in MySports you can see the all day activity tracking and see the HR and when it was higher, but again it is at a much large collection interval than if you have started an activity. Unlike other brands it does not auto detect activities and switch to recording mode, you need to remember to do it yourself.
