The goal of this clinical trial is to investigate changes in cognitive and physical performance after 10 weeks of dual or single task training in anterior cruciate ligament (ACL) reconstructed individuals. The main questions it aims to answer are:
Researchers will compare a combined dual-task training (combined physical and cognitive training) to a single task training (physical and cognitive training separately) to see if there are changes on cognitive performance depending on the training type.
Participants will:

| Kujala | The German version of the 13-item Kujala questionnaire will be used for assessment of anterior knee pain. Questions involve ability to do several activities and symptoms of patients. All scores of the 13 items are summed up to give a total score ranging from 0 to 100. High scores indicate a good outcome. | Baseline and after 10 weeks of training |

| Single task training | Other | Sequential cognitive and then physical training |
|
| Baseline and after 10 weeks of training |
| Strength | Peak force of hamstring, quadriceps, hip abduction, and hip adduction | Baseline and after 10 weeks of training |
| Intrinsic motivation | German version of the short scale for intrinsic motivation (Kurzskala Intrinsische Motivation). For each of the 12 items there is a 5-point Likert-Scale resulting in values of 0-4. Therefore, the total score ranges from 0 to 48. The higher the score, the higher the intrinsic motivation. | At the end of each training session (2x/week for 10 weeks) |
| Kinematics and kinetics of the lower extremities | Hip, knee, and ankle angles and moments and ground reaction forces | During dual-task training in an immersive environment |
| Kinematics and kinetics of the lower extremities | Ground reaction forces, angles and moments of hip, knee, and ankle during functional tasks | Baseline and after 10 weeks of training |
| ACL-Return to Sport after Injury Scale | The German version of the ACL-RSI will be used. The ACL-Return to Sport after Injury Scales includes 12 items which are each answered on a Likert-scale from 0 to 100. For the total score, individual scores of each item are added and subsequently divided by the numer of questions. Hence total score ranges from 0 to 120. High scores indicate a positive psychological evaluation. | Baseline and after 10 weeks of training |
| Tegner Activity Scale | The German version of the Tegner Activity Scale including 11 different stages will be used. Each stage includes activities in sports and work of patients after ACL injury. Stages range from 0 to 10. | Baseline and after 10 weeks of training |
| Socio-demographic data | Sex, age, time since ACL reconstruction, injury history | Baseline |
| Subjective Cognitive Load | Measured by the NASA-TLX questionnaire | At the end of each training session (2x/week for 10 weeks) |
