Exercise has been shown to prevent vision decline by preserving the function of retinal nerve cells. [사진=클립아트코리아]As we age, the function of photoreceptors, which are retinal nerve cells that detect light, declines and vision decreases. One of the main causes of vision loss in older people is the decline in vision due to aging.
However, moderate-intensity exercise, such as aerobics, has been shown to be helpful in preserving the function of retinal nerve cells that are undergoing damage.
According to a research team at Emory University in the United States, exercise slows the progression of retinal degenerative disease. Several studies have proven that exercise is effective in preventing diseases or injuries caused by neurodegeneration.
However, no proper research has been conducted on whether exercise can have a positive effect on vision. To prove the connection between exercise and vision, the Emory University research team conducted an animal experiment in which rats ran on a treadmill.
The experimental rats were trained to run on a treadmill for 1 hour a day for 5 days for 2 weeks. The results revealed that treadmill training preserved the function of photoreceptors and retinal cells in mice.
Rats that received training lost significantly less photoreceptors than rats that spent the same amount of inactivity on a stationary treadmill. The retinal cells of mice that exercised had an excellent ability to respond to light, and the levels of brain nerve growth factor (BDNF), which is known to be associated with the beneficial effects of exercise, were also high.
Additionally, when the research team blocked the BDNF receptors in mice that exercised, their retinal function decreased to that of inactive mice. The research team said, “This is the first experiment to discover that exercise has a direct effect on retinal health and vision,” and added, “Through this study, exercise therapy for elderly people suffering from vision impairment may be developed.”
“This study increases our understanding of the neuroprotective effects of exercise and the role of BDNF,” the experts said. “It may help slow the process of vision impairment in people at high risk of vision decline or who show signs of retinal disease.” He said.
The results of this study (Aerobic Exercise Protects Retinal Function and Structure from Light-Induced Retinal Degeneration) were published in The Journal of Neuroscience.
