To the Editor A recent article1 in this journal examined the energy expenditure of active video games (AVGs). It provided a rationale for AVGs, which are thought to increase adolescents’ physical activity and contribute to obesity prevention. This small study (N = 18 adolescents aged 11-15 years) examined the energy expenditure of 2 AVGs. One AVG reached “moderate intensity” and another, only light intensity levels of energy expenditure, but both demonstrated greater energy expended than playing a sedentary video game. This study repeats the findings of many similar studies2 and now reviews and meta-analyses3 over the last few years demonstrating a short-term increase in energy expenditure. However, from a public health perspective, is this kind of AVG intervention really likely to produce population-level improvements in the established risks of inactivity and obesity among adolescents?
