Abstract
The application of Near Infrared Spectroscopy (NIRS) to biological tissues has allowed the non-invasive measurement of local tissue oxygenation in vivo. Simultaneous measurements of local tissue oxygenation at multiple sites can be used to determine the distribution of oxygen supply and utilisation during exercise. Comparison of oxygenation at locomotor muscles versus the brain provides an indication of peripheral versus central mechanisms of fatigue during exercise. Regular aerobic exercise produces lower systemic oxygen utilisation, pulmonary ventilation, blood pressure, and heart rate, and increased oxygen transfer in muscle tissue during exercise. Exposure to tobacco smoke, either directly via smoking or indirectly from environmental tobacco smoke (ETS), is associated with changes in pulmonary ventilation, resulting in dyspnoea during exercise, and decreased oxygen supply and exercise capacity. Aging is associated with a decrease in the supply of oxygen to active tissues. A series of projects are being conducted to determine the effects of exercise, ETS exposure, and aging on changes in local tissue oxygenation, and the distribution of these changes across multiple muscle and brain sites. Preliminary results will be presented. The results of these projects will be used to understand the mechanisms of exercise capacity and fatigue.
