Objective: To analyze the metabolic responses occurring during the practice of exergames in terms of energy expenditure, oxygen consumption rate, metabolic equivalent and heart rate in adult men and women. Methods: The present study sample was comprised of 102 adults (52 males). Energy expenditure, oxygen consumption rate and metabolic equivalent were assessed with a portable gas analyzer (K4b2). Heart rate was measured with a frequencymeter. All dependent variables were assessed at rest and during the exergame session, which was comprised of four X-box 360 games (volleyball, boxing, athletics, and bowling). Results: Mean age was 34.8 ± 13.4 years. There was a significant increase in resting values during exergame sessions for energy expenditure (male: 467.52%; p < 0.001; female: 393.72%; p < 0.001), oxygen consumption rate (male: 453.97%; p < 0.01; female: 384.74%; p < 0.001), metabolic equivalent (male: 457.40%; p < 0.001; female: 384.74%; p < 0.001) and heart rate (male: 95.10%; p < 0.001; female: 92.26; p < 0.001). When compared to women, men showed significantly higher values for energy expenditure (95% confidence interval = -12.53; -6.67), oxygen consumption rate (95% confidence interval = -4.01; -0.80) and metabolic equivalent (95% confidence interval = -1.18; 0.27) during exergames. Conclusion: A session of exergames is capable of increasing energy expenditure, oxygen consumption rate, metabolic equivalent and heart rate in adults. Men showed higher values in metabolic parameters when compared to women.
