Many older adults could benefit from additional exercise. In 2011, over 54% of adults between the ages of 65 and 74 and 68% of adults ages 75 and above did not meet the 2008 U.S. Federal Physical Activity guidelines for either aerobic or muscle strengthening activities, according to the National Center for Health Statistics (Schiller, Lucas, & Peregoy, 2012, p. 100). Exergames, video games where players engage in physical activity, could help older adults elevate their levels of physical activity in order to gain associated health benefits. However, most exergames on the market are not designed for older users. Two exergames for Microsoft Xbox 360 with Kinect were evaluated using heuristic task analysis and heuristic evaluation with consideration of older adults' abilities and limitations. Implications for developing training programs to maximize effective use of exergames for older adults are discussed.
