Interventions
Group 1: Metastable resistance training 2x/week á 60 min
whole body resistance training with free weights on unstable devices (e.g. Squats, Front Lunges, Bridge Exercise, Crunches)
Group 2: machine-based resistance training 2x/week á 60 min
whole body resistance training on machines (e.g. Squats at the Smith Machine, Bridge Exercise, Crunches, leg press)
Group 3: Balance Training 2x/week á 60 min
balance training with bipedal, monopedal and tandem stance on unstable devices
variation by changing unstable devices, open and closed eyes during the exercise and catching and throwing of a ball

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Cognitive performance and executive functions (EF) using different computer tests. Higher-Level EF: initial thinking time and the number of (optimal) solved problems in the Tower of London Task before and after the intervention (pre/post), Inhibition: time ratio of between reaction time for color words (interference condition) and colored circles (Stroop Score) in a visual-verbal Stroop Task (Pre/Post). working memory/updating: maximum number of correctly reproduced numbers in a digit span backwards task (pre/post) cognitive flexibility/shifting: reaction time and response accuracy in a task switch paradigm (pre/post) spatial perception: reaction time and response accuracy in a Visual Search Task (Pre/Post) cognitive-motor interference: time and dual-task costs in a trail walking task | — |
Secondary
| Measure | Time frame |
|---|---|
| Physical and motor performance using various tests: Maximum leg strength (isometric) in newtons (N) (Pre/Post). body cell mass in kilograms (kg) by means of bioelectrical impedance analysis (Pre/Post) Functional capacity of leg extensors by means of time in seconds in a 5x sit-to-stand test (Pre/Post) Maximum strength of hand grip in kg by means of Electronic Hand Dynamometer (pre/post) Balance by means of the sum score in the mini-BESTest (pre/post) dynamic-continuous balance by means of time in seconds in a 4m-walking task (pre/post) | — |
