There is a substantial lack of research comparing the effects of game console-based activities against conventional activities (aerobic, bicycle ergometer) within therapeutic and rehabilitative settings and the results are inconsistent. The aim of the study was to investigate if training with exergames (Nintendo Wii vs. Xbox 360) compared with conventional activities (bicycle ergometer) would have different effects on physiological and psychological parameters. Method: A quantitative three-armed, randomised, not-blinded study design was used. The test persons were randomly assigned to one of three activities: 1) Bicycle ergometer (n = 6); 2. Nintendo Wii game (n = 16); 3. Xbox 360 game (n = 17).

In terms of Evidenced Based Training, however, there is a scientific lack of facts regarding the efficiency of different physical criteria and training methodology. By means of a meta-analysis including 45 primary studies and a total num ber of 1712 participants, 203 effect sizes in pre-post design were identi-fied regarding the variation of maximum strength. The effect sizes found differed depending on individual preconditions, such as train ing status, gender, age, and methodological variables like du-ration of study, total training frequency, training parameters, etc.
