Abstract:
This study was designed to determine whether improvements in both cardiovascular fitness and hearing sensitivity occurred following 2 months of aerobic exercise training. Seventeen moderately-low fit (VO2 peak <32 ml/kg/min) young adults were evaluated for cardiovascular fitness and pure-tone and temporary threshold shifts (TTS) at 2, 3, and 4 kHz before and following 10 min of noise. Subjects exercised for 8 weeks by cycling on a bicycle ergometer at 70% of their peak oxygen consumption (VO2 peak). Average VO2 peak increased 34% (p < 0.05) above pre-exercise training levels. Both pure-tone hearing (2 and 3 kHz) and TTS improved following 2 months of exercise training at the evaluated frequencies (2, 3, and 4 kHz) (p < 0.05). Cardiovascular health as indicated by VO2 peak was associated with hearing sensitivity. Although the mechanisms have not been identified, these results support the existence of a cardiovascular health-hearing synergism.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
