[Purpose] This investigation evaluated the acute cardiovascular responses that occur
while playing virtual games (aerobic and balance) emulated by Nintendo Wii®.
[Subjects] Nineteen healthy male volunteers were recruited. [Methods] The ergospirometric
variables of maximum oxygen consumption, metabolic equivalents, and heart rate were
obtained during the aerobic (Obstacle Course, Hula Hoop, and Free Run) and balance (Soccer
Heading, Penguin Slide, and Table Tilt) games of Wii Fit Plus® software. To
access and analyze the ergospirometric information, a VO2000 analyzer was used. Normalized
data (using maximum oxygen consumption and heart rate) were analyzed using repeated
measures analysis of variance and Scheffe’s test. [Results] Significant differences were
found among the balance and aerobic games in all variables analyzed. In addition, the Wii
exercises performed were considered to be of light (balance games) and moderate (aerobic
games) intensity in accordance with American College Sports Medicine exercise
stratification. [Conclusion] Physical activity in a virtual environment emulated by
Nintendo Wii® can change acute cardiovascular responses, primarily when Wii
aerobic games are performed. These results support the use of the Nintendo Wii®
in physical activity programs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
