Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Methods/Design Healthy old people (N = 66) between the age of 65 to 80 years will participate in this trial. The testing protocol comprises tests for the assessment of static / dynamic steady-state balance (i.e., Sharpened Romberg Test, instrumented gait analysis), proactive balance (i.e., Functional Reach Test; Timed Up and Go Test), reactive balance (i.e., perturbation test during bipedal stance; Push and Release Test), strength (i.e., hand grip strength test; Chair Stand Test), and power (i.e., Stair Climb Power Test). Further, body composition will be analysed using a bioelectrical impedance analysis system. In addition, questionnaires for the assessment of psychosocial (i.e., World Health Organisation Quality of Life Assessment-Bref), cognitive (i.e., Mini Mental State Examination), and fall risk determinants (i.e., Fall Efficacy Scale - International) will be included in the study protocol. Participants will be randomized into two intervention groups or the control / waiting group. After baseline measures, participants in the intervention groups will conduct a 12-week balance and strength / power exercise intervention 3 times per week, with each training session lasting 30 min (without warm-up and cool-down). One intervention group will complete a supervised training program (2x supervised training per week / 1x home training per week), while the other intervention group will complete a training after the same protocol that is home-based (3x home training per week) and controlled by phone calls every two weeks. Post-tests will be conducted right after the intervention period. Additionally, detraining effects will be measured 12 weeks after program cessation. The control group / waiting group will not participate in any specific intervention during the experimental period, but will receive the extensive supervised program after the experimental period.
Discussion It is expected that particularly the supervised combination of balance and strength / power training will improve performance in variables of balance, strength / power, body composition, cognitive function, psychosocial well-being, and falls self-efficacy of older adults. In addition, information regarding fall risk assessment, detraining effects, and supervision of training will be provided. Further, training-induced health-relevant changes, such as improved performance in activities of daily living, cognitive function, and quality of life, as well as a reduced risk for falls may help to lower costs in the health care system. Finally, practitioners, therapists, and instructors will be provided with a scientifically evaluated, feasible, safe, and easy-to-administer exercise program for fall prevention.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Exercise with supervision
The expert panel selected balance and strength / power exercises which can be performed with one's own bodyweight or with the help of small, low-cost exercise equipment (i.e., small weights, resistance bands, unstable surfaces). In this study, intensity during training will be regulated using the Borg Rating of Perceived Exertion scale (i.e., 6-20 points, maximal exertion at 20 points). According to the individual fitness level, exercises should be performed with a perceived exertion between 12 and 16 points (somewhat hard - hard) during balance and strength / power training. Exercise intensity will be progressed individually using the Borg Rating of Perceived Exertion scale and varying the balance and strength / power exercises in order to sufficiently stimulate the neuromuscular system. Strength / power exercises will be progressed from single to multiple joint, isometric to dynamic muscle contraction, short to long lever arm and slow to fast exercises.
