exercise standards. Tools such as the Nintendo Wii—with boxing, tennis and
bowling simulations, as well as dance programs—have recently been tested by
researchers at the University of Michigan Health System (UMHS).

According to a March press
release, exergames are effective for increasing physical activity among
youngsters. However, caloric expenditure is not high enough to yield
significant results. Colleen Greene, MA, wellness coordinator for the health
promotion division of UMHS, states that “real calories can be burned during
virtual gaming, although some studies have recently shown that it may be 60–70

which is three to four times that amount.”

While exergames may not elicit

programs can still be useful in motivating sedentary kids to increase their
