Yes. Whenever your life total goes up, it counts as gaining life. This can be through an effect that specifically says "Gain X life", an effect that doubles your life total, or an effect (such as Biorythm) that sets your life total to a certain number, assuming that number is higher than your current total.
On a similar note, whenever your life total goes down (again, for any reason), it counts as losing life.
