"Fitzgerald and her colleagues (2004) compared exercising with an arm ergometer (without a videogame) to exercising with the GameCycle (arm ergometer with videogame). Fitzgerald found that although metabolic data indicated that more calories were being expended while using the GameCycle (compared with the standard arm ergometer), research participants did not perceive greater exertion. In other words, participants were exercising harder with the GameCycle, but did not feel it or realize it."
