Vision and Exercise

Recent research has shown that exercise  as well as elevating the heart rate may improve vision.

The wide array of benefits from physical exercise is long,including mood enhancement, improved sleep, reduced risk of disease and now researchers believe vision improvement can be added to the mix.


A recent study at UC Santa Barbara recorded vision improevemnt among 18 subject participants who had riding a stationary bike at low intensity.

Tom Bullock a post-doctoral researcher at UC Santa Barbara,said that previous studies had resulted in improved vision among mice during physical activity.

“However, given the vast differences between mouse and primate brains, it is unclear whether these results also apply to the human brain,” he elaborated. “Our data provides evidence that there may well be a common mechanism,” Dr Bullock stated.

During the research program, the 18 volunteers each wore a skull cap cover containing scalp electrodes and a wireless heart rate monitor. The visual neural activity was analysed while the study participants were at rest, as well as during a variety of cycling intensity exercise.

Reconstructed tuning curves using a computational algorithm, allowing researchers to estimate how well large populations of neurons in the visual cortex
were representing different stimulus orientations.

The results suggested that the neurons became more sensitive to visual stimuli during low intensity exercise than during high intensity exercise or rest.

Other research planned by the lab includes a study determining how exercise influences visual working memory.
