Northumbria University scientists find looking in the mirror makes you stronger

Experts at Northumbria University, Newcastle are working with Newcastle Clinic to explore how innovative new research on muscular strength in healthy adults could be applied to accelerate recovery from strokes and limb fractures.

Researchers within the Department of Sport, Exercise and Rehabilitation at Northumbria have gained valuable insight into the way muscles are strengthened and in doing so, have partnered together with Newcastle Clinic with the aim to apply this work in athlete injury management.

The research found that when a person exercises a muscle on one side of their body in front of a mirror, the muscle on the opposite side can also get stronger due to the reflection stimulating a specific areas the brain. Through the illusion of the stationary hand moving and its muscles contracting during strength training, the excitability of the untrained muscle on the opposite side is stimulated and as a result, strengthened.

This new research has the potential to be crucial in the future of stroke rehabilitation, fractures or other unilateral clinical injuries and in collaboration with Newcastle Clinic, experts will be able to analyse sports injuries with speedy access to state of the art MRI equipment.

Explaining the next stage of the research, Professor Glyn Howatson, a Sport and Exercise Physiologist from Northumbria, said: “Volunteer participants will be immobilised in a wrist cast for 1 week and we will measure, with an MRI scanner, how the muscle structure changes with and without resistance training on the opposite side.

We are very excited at the potential application of this work in athlete injury management and perhaps more importantly in clinical populations, such as stroke and fractures, that require rehabilitation.”
