Would be interesting to know how long the effect lasts, e.g. will 1h, 12h or 24h between the physical exercise and the test make a difference. If it's say ~8 hours, then scheduling gym classes in the beginning of school days may help these children. If it's 1h it won't matter much, as long as gym isn't at the end of a school day.
