Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Resistance training control group

The resistance training control group will perform unilateral resistance training on their dominant arm. The training will be performed twice per week for four weeks totaling eight training sessions.

Group Type ACTIVE_COMPARATOR

Unilateral resistance training

Intervention Type OTHER

Unilateral resistance training of the elbow flexors

Resistance training with mirror illusion group

The resistance training with mirror illusion group will perform unilateral resistance training on their dominant arm. During training, they will view a mirror illusion of their exercising arm over their opposite, non-exercising arm. The training will be performed twice per week for four weeks totaling eight training sessions.

Group Type EXPERIMENTAL

Unilateral resistance training

Intervention Type OTHER

Unilateral resistance training of the elbow flexors

Illusionary mirror visual feedback

Intervention Type OTHER

Modified Ramachandran's mirror box
