Optimizing Hamstring Activation Through EMG-Feedback and the Hamshell Device
Sponsor: Praxisklinik Rennbahn AG
Summary
In this study, we investigate whether training of the posterior thigh muscles with visual feedback on muscle activity is more effective than the same training without feedback. To this end, healthy, physically active adults complete a training programme on a training device twice a week for five weeks. Muscle strength, muscle activity, and flexibility are measured before and after the training. Participants are randomly assigned to one of two groups: one group trains with feedback on muscle activity, the other without. Participation involves minimal risks, similar to those of a typical strength training session (e.g. muscle soreness). The aim of the study is to improve training methods for the prevention of muscle injuries.

Interventions
EMG-Biofeedback-Training
Participants complete 10 training sessions with EMG feedback over a 5-week period. The training is designed to optimize biceps femoris and gluteus maximus activation at extended knee angles using the Hamshell device. All training sessions last approximately 30 minutes and are conducted at the Rennbahnklinik. The first and middle training sessions are supervised to ensure correct exercise execution and appropriate progression. During these supervised session, EMG will be recorded.
Control
Particpants in the control group will perform the same training as the intervention group but without EMG feedback.
