Influence of Age on Ventilatory Pattern during Exercise
Previous investigators have reported that exercise capacity is decreased in the elderly with the reduction in maximal oxygen uptake1). We have previously demonstrated that healthy elderly achieve greater V-̇E/V-̇O2 for a given exercise load than the young during exercise2). However, the pattern of ventilation on exercise has not been extensively evaluated and little is known as to the changes in the fractional contribution of abdomen vs thorax in relation to total ventilation during exercise in old age.
