    I’m having this problem now. Trying to switch off/on my watch.

  • Respiration is measured using heart rate variablility (HRV). It requires quite a good signal from the heart rate over a longer period, such as a minute or two. Any movement can disturb this reading. From my experience, this graph doesn't look abnormal. If you want accurate HRV graph, connect a chest HRM. I know the newer EDGE 530 do this during excercise. Not sure if the VA4 can actually do it from a chest HRM.
