The amount of energy adults expend playing active video games may equal that of moderate-intensity exercise, according to a new study.
Japanese researchers measured the metabolic equivalent values (a standard method of estimating energy expenditure) of 12 people ages 25 to 44 as they played Wii sports games and did Wii fitness programs. The study was funded by Nintendo, which makes Wii.
The study found that nine Wii activities had less than two metabolic equivalent values (METs); 23 activities had two to three METs; nine activities had three to four METs; and five activities had more than four METs. The least intense activity was lotus focus (1.3 METs), and the most intense was the single-arm stand (5.6 METs).
