Researchers found that sedentary mice lost structures that are important in the auditory system—hair cells and strial capillaries—at a much higher rate than mice that exercised. This resulted in a roughly 20-percent hearing loss in sedentary mice compared with a 5-percent hearing loss in active mice.
Age-related hearing loss affects about 70 percent of adults age 70 and older and occurs when people lose hair cells, strial capillaries, and spiral ganglion in the cochlear system of their ear.
