Combined mental and physical training in an immersive environment compared to sequential mental and physical training in individuals with reconstructed anterior cruciate ligament
Summary description of the study
Anterior cruciate ligament tears commonly occur in sports and lead to a rehabilitation time of up to one year. Individuals after an ACL tear show a persistently altered movement pattern and deficits in mental functions such as reaction inhibition. However, when individuals are in an immersive environment after an ACL tear, their movement pattern resembles that of healthy individuals. Dual-task training, a combined mental and physical training, improves mental functions in female team sport athletes. Therefore, dual-task training in an immersive environment, for example through exergaming, offers great potential to improve these factors. Thus, we investigate in this study what changes occur in mental and physical functions, as well as in motivation, when training with or without dual-task for 10 weeks. We also examine how dual-task training in an immersive environment affects biomechanical movement patterns. The aim of this study is to investigate how physical and mental functions change when training with or without dual-task for 10 weeks, how intrinsic motivation changes over 10 weeks, and how dual-task training in an immersive environment affects biomechanical movement patterns. Individuals aged between 18 and 40 years who have had an ACL tear at least six months ago and have received clearance for single-leg jumps will be recruited for the study. In a first appointment, physical and mental tests will be conducted. In a second appointment, biomechanics will be measured during immersive dual-task training. Participants will then be randomly divided into two groups. For 10 weeks, participants will either complete an individually guided training or a dual-task training twice a week. In a final appointment, the tests will be repeated to observe differences compared to the first.
