Physiological Responses and Hedonics During Prolonged Physically Interactive Videogame Play

This study was designed to assess physiologic responses and hedonics (i.e., liking) during prolonged physically interactive videogame play.

Participants (n = 24) completed three 30-minute videogame conditions on separate days in a random order. During two of the conditions participants played physically interactive videogames (Nintendo of America, Inc. [Redmond, WA] "Wii™ Fit" "Basic Run" and "Basic Step"). During the third condition participants played a traditional/sedentary game ("Tanks!"), which required minimal physical movement for gameplay. Oxygen consumption (VO2) was assessed using indirect calorimetry throughout each condition and averaged every 5 minutes. Liking was assessed via visual analog scale at the 15- and 30-minute time points during each condition.

Mean VO2 was significantly (P < 0.001) greater during "Basic Run" (16.14 ± 5.8 mL/kg/minute, 4.6 ± 1.7 metabolic equivalents [METs]) than either "Basic Step" (11.4 ± 1.7 mL/kg/minute, 3.3 ± 0.5 METs) or the traditional/sedentary videogame (5.39 ± 1.0 mL/kg/minute, 1.5 ± 0.1 METs). "Basic Step" was also greater (P < 0.001) than the traditional/sedentary game. VO2 did not significantly (P = 0.25) fluctuate across the 30-minute session for any game. In other words, participants maintained a consistent physiologic intensity throughout each 30-minute condition. There were no differences (P ≥ 0.20) across gaming conditions or time for liking.

Participants achieved and maintained moderate-intensity physical activity (≥3.0 METs) during both 30-minute physically interactive videogame conditions. Furthermore, because liking was similar across all gaming conditions, participants may be willing to substitute the physically interactive videogames in place of the traditional/sedentary game.
