In Russian, there is a popular concept "Физкульминутка" (Physical culture minute) - this is a very short break in the middle of a lesson for physical exercise to rest. Is there a term in English for this? What do you call these breaks - exercises like "clap your hands, stamp your feet, ..."?
I’m not aware of any established term, but “(short) exercise break” is a clear term that needs no definition. Here are some examples in use:
One to two exercise breaks, held daily in school, will contribute significantly to the goal of a total of 30 minutes of activity each day for every child. — Active Breaks (download)
Alternatively, I have also seen the following used, less commonly:
- Movement break
- Fitness break (seems to indicate a bit more rigor)
- Physical activity break (a bit wordy and slightly formal)
The term “brain break” is close but the activities it covers don’t all involve exercise (such as mindfulness).
I think you might be looking for the term "brain break":
A brain break is a break from whatever kids are focusing on. Short brain breaks during work time have been shown to have real benefits. They reduce stress and frustration and increase attention and productivity. (1)
In the classroom, brain breaks are quick, structured breaks using physical movement, mindfulness exercises, or sensory activities. Brain breaks can be done individually (like deep breathing) or as a whole class (like a round of Simon Says). (2)
A brain break is a short mental break that is taken during regular intervals during classroom instruction. Brain breaks are usually limited to five minutes and work best when they incorporate physical activities.
