Brief Summary in Lay Language

In everyday life we are often confronted with situations in which we have to carry out several tasks at the same time, so-called multitasking (e.g. driving a car while talking to a passenger, walking through the city while writing a message on the smartphone, etc.). With increasing age, multitasking becomes more difficult; the consequences are reduced performance, failure, and increasing risks of accidents and injuries. In long-term this can even lead to the loss of an independent and autonomous life. Scientific studies suggest that age-related changes in cognitive and motor functions and the associated restrictions in everyday life can be counteracted by targeted and tailored training. The aim of this project is to find out how exactly such a training intervention has to be designed in order to successfully improve multitasking skills. Study participants between 65 and 75 years of age are monitored for several months. They take part in different training interventions that train both mental and physical fitness. The success of the training is assessed by motor, neurophysiological and cognitive tests before and after the training phase.

Brief Summary in Scientific Language

The objective of the project is to investigate the benefits of individualized, adaptive training ("tailored training") to improve cognitive-motor multitasking. In a randomized, single-blind, three-armed, twelve-week intervention-study, subjects will be assigned to one of three experimental groups: (1) motor training, (2) cognitive training (3) cognitive-motor multitasking-training. Different motor, cognitive, physiological and neuronal measures are assessed in pre- and post-tests. The study aims to find out whether (1) subjects with motor deficits benefit more from a purely motor training than from multitasking-training, (2) subjects with cognitive deficits benefit more from a purely cognitive training than from multitasking-training, and (3) subjects without motor and cognitive deficits benefit more from multitasking training than from a purely motor or purely cognitive training.

Interventions/Observational Groups

  •   Twelve-week cognitive training. The contents are composed of different cognitive tasks. The sessions take place in groups twice a week for 45-60 minutes. Before and after the intervention, cognitive and motor performance as well as other personal and psychological variables are assessed.
  •   Twelve-week motor training. The contents consist of various balance, flexibility and strengthening exercises. Except for the contents of the training, all variables are kept the same as in Arm 1.
  •   Twelve-week cognitive-motor multitasking-training. The contents consist of the same exercises as in cognitive and motor training and are executed in combination (i.e. a simultaneous execution of cognitive and motor tasks). Except for the contents of the training, all variables are kept the same as in Arm 1 and Arm 2.

start of 1:1-Block primary endpoint

Primary Outcome

The primary endpoint is the identification of the influence of training effects on the behavioral (cognitive and motor) and neural level in regard to the initial cognitive and motor performance in (virtual) scenarios containing multiple tasks. All examinations are carried out in longitudinal section at two measurement points at a time interval of twelve weeks (before and after the intervention).

Measurement instruments:
- Tracking task (in combination with a motor-auditiv task)
- Virtual driving task (realistic multitasking task)
- Virtual walking task (realistic multitasking task, in combination with the Stroop test and the Digit Symbol Substitution test)
- fNIRS

Secondary Outcome

The secondary endpoint is the assessment of general physical and cognitive fitness. All examinations are carried out in longitudinal section at two measurement points at a time lag of twelve weeks (before and after the intervention).

Measurement instruments:

- Campimetry test
- German adaptation of the Baecke Physical Activity questionnaire
- German adaptation of the Falls Efficacy Scale
