with less time being devoted to recess and physical education in schools, children and teachers need good ways to incorporate exercise into the school day. researchers at queen’s university in kingston, ontario, have developed a time-effective, fun, and easy-to-implement exercise program. and there’s evidence that it can improve not only health and fitness, but school performance as well.
funtervals are a series of very brief (four-minute) in-class exercise activities. these activities were adapted from high-intensity interval training and allows participants to achieve health benefits comparable to those gained by performing an hour of traditional endurance training. funtervals involve 20 seconds of activity followed by 10 seconds of rest, repeated for eight intervals. to make these high-intensity activities more appealing to children, actions that involve the child’s whole body — such as squatting, jumping, and running — complement fun, interactive storylines. for example, instead of instructing students to do a squat and press, teachers tell children to reach for an imaginary top shelf to grab a bag of popcorn and placing the bag in a giant bowl on the ground to make popcorn for the entire school.
the researchers have studied the effects of funtervals on schoolchildren in grades 4 and 5, comparing the children’s behaviour on days when they did funtervals to days when they did not. on days when they did funtervals, the students were less fidgety and less likely to get out of their seats, made more eye contact with the speaker, were more alert and were better able to pay attention.
funtervals have been implemented in countries around the world, including canada, australia, new zealand, china, south africa, india, and the united states.
