Study Summary

Cross-education describes the transfer of motor performance to the opposite limb following unilateral training and is primarily explained by adaptations within the brain. The mirror training hypothesis suggests that illusionary mirror visual feedback may augment the cross-education of strength to the untrained, contralateral limb. The purpose of this project is to examine how the use of illusionary mirror visual feedback shapes the neuromuscular adaptations that occur for both limbs during unilateral (single-limb) strength training. Our hypothesis is that mirror training will augment the level of cross-education for the untrained arm.

Study Description

Recent empirical evidence shows a heightened level of strength transfer with the use of illusionary mirror visual feedback, but this was shown for the small muscles of the wrist during isokinetic training. It is unknown if larger, multi-joint muscles respond favorably to mirror training in practical settings. A randomized controlled study design will allocate approximately 20 participants into two groups. One group will perform unilateral strength training with illusionary mirror visual feedback (Mirror) and the other will perform the same unilateral strength training but without a mirror (No-Mirror). The intervention will involve four weeks of unilateral strength training performed twice weekly at high intensities (>80%1RM).
