The purpose of this study was to quantify the cardiovascular responses and enjoyment of one trial of electronic exercise gaming (EG) (Nintendo(®) Wii(™) Tennis) in healthy, older adults (mean age = 81 [SD = 4 years]). Findings indicate that 15 minutes of EG moderately increased heart rate (p < 0.001), blood pressure (p < 0.001), and perceived exertion (p < 0.0001) compared to resting levels. This corresponded to achieving 64% of age-predicted maximum heart rate. No differences were observed for the cardiovascular responses to EG between genders, but participants taking beta-blocker drugs showed an attenuated response (p < 0.05). All participants completed EG tennis without excessive fatigue, with 86% of participants enjoying the experience. There were only a few cases of EG-related arrhythmias (n = 2) and post-exercise muscle soreness (n = 3). These results suggest that Nintendo Wii Tennis EG technology represents an enjoyable, moderate intensity physical activity for healthy, older adults.
