Exercise session with the Nintendo Wii: behavior of hemodynamic variables, caloric expense and feel exertion.

Abstract

This study analized the behavior of the hemodynamic variables, subjective sensation of effort and energy expenditure during an exercise session physicists using the Nintendo Wii Fit® of young adults. Sixty volunteers (35 men; 25 womens) were recruited from the university population, aged 22.8 ± 3.4 years (men) and 21.5 ± 2.6 years (women). The exercise session lasted 45 minutes and was composed of nine games, through the Nintendo Wii Fit®. The hemodynamic variables were collected in periods of rest, recovery and the end of each game, along with the subjective sensation of effort and the body mass. In the Statistical analysis were employed: the Shapiro-Wilk test; Descriptive Analysis and Analysis of Variance One Way (ANOVA); and the post hoc Tukey. All analyses were conducted in SPSS, version 14.0, with statistical significance set at p<0.05. Findings showed that the exercise session produced acute cardiovascular changes and caloric expenditure as recommended by the American College of Sport Medicine. Data from this study suggest that a session of 45 minute of the physical exercises fostered by Wii Fit® can be used as an effective mode of physical activity to improve health.
