Two recent trials examined whether regular engagement in virtual-reality enhanced exercise that combines physical activities with computer-simulated environments affects cognitive performance in older age. In one trial, an intervention group (n = 38; mean age = 76 years) was cycling in an interactive virtual environment for 45 min up to five times per week for 2 months. The control group (n = 41; mean age = 82 years) was cycling without the virtual environment. Outcome measures were assessed before training and immediately after the intervention. Significantly larger improvements for the cybercycling group than for the control group were observed on measures of executive functioning, but not on measures of attention, verbal fluency, episodic memory, and visuo-spatial memory. In the second trial, an intervention group (n = 15; mean age = 73 years) was playing Nintendo Wii games (e.g., Wii Tennis and Wii Boxing) during two 1-h sessions per week over a period of 12 weeks, and a no-contact group served as control (n = 15; mean age = 73 years). Results included training-related effects on measures of executive functioning and perceptual speed. These findings should, however, be interpreted with caution because the control group did not receive any placebo condition. Nevertheless, these trials demonstrated the feasibility and advantages of virtual-reality enhanced exercise, which is easy and more fun to perform than exercising without games, so that people will do exergaming more often than ordinary physical exercise
