Researchers suggests that a pre-performance routine (PPR) can improve performance in competitions. The effectiveness of left-hand contractions, a PPR to trigger facilitative cortical processes for skilled motor performance, was tested in two studies. In Study 1, gymnasts competing at the German university championships in artistic gymnastics performed their routines with or without the PPR. In Study 2, gymnasts performed the balance beam exercise either using the PPR or the control task (right-hand contractions) under simulated competition pressure. The qualification performance (Study 1) and the pressure-free performance (Study 2) were controlled. In both studies, participants in the PPR group performed better than control participants. The results indicate that left-hand contractions may be a useful PPR in the field.
