Outcomes
CC was assessed in a standardized cycle course which was originally developed to test the motor competence of school children. We used a modified and validated version with seven tasks (see Supplementary file 1 “Cycle course tasks”) that is feasible and safe for older adults [Mean change in number of errors (IG vs. aCG) was tested as primary outcome between T0 (baseline) and T1 (after three months intervention period). In addition, we analyzed whether an intervention effect is sustainable to T2 (after six-nine months to T1).
