BSO: narrowing the base of support; CD: cognitive demand; COM: displacing the center of mass; CR: cardiorespiratory fitness; HRR%: percentage of heart rate reserve; LE: lower extremities; : mean; ME: muscular endurance; MET: Metabolic Equivalent of Task; PE: perceived exertion; ROM: range of motion; SD: standard deviation; rho: Spearman’s rank correlation; UE: upper extremities. Number of rater assessments (2 raters 5 exergames). Five exergames were assessed. Their METs were provided by Wii Fit U: “Warrior” (2 METs), “Rowing Squat” (3.5 METs), “Basic Run” (5.0 METs), “Beginner Dance” (2.5 METs), and “Ski Jump” (2.0 METs). The exergame of “Basic Run” was not included in the calculation.
