Correlations between aerobic capacity, pulmonary and cognitive functioning in the older women

Regular aerobic exercise improves aerobic capacity and increases brain blood flow and oxygenation. Exercise also stimulates the reticular activating system and leads to a centrally excited state thereby makes the brain active and alert. In the present study, an aerobic exercise program consisting of submaximal level calisthenic exercises was devised for relatively healthy women between 60 and 80 years old, attending a solidarity center for the aged for daily activities. The effects of exercise on aerobic fitness, and the correlations between aerobic capacities, pulmonary functions and cognition were evaluated. Following a general health examination, 45 female volunteers fulfilling the international criteria of exercising standards for the aged were included in the program. The rhythmic and entertaining calisthenic exercises were performed by the older women for four months, three days a week, 40 or 50 minutes a day. Tests for aerobic capacities, pulmonary functions, and some neuropsychologic performances were carried out during the sedentary period and after the exercise program. The results revealed significant improvements in aerobic capacity, pulmonary functions, and some of the cognitive functions after the 4-month exercise program. We found strong relationships between aerobic capacities and cognitive functioning. Overall, the subjects expressed their happiness and well being on every occasion, during and after the exercise program.
