At first, the leg ergometer was used with constant 50 rpm and the initial intensity of 50 watts and 25 watts were added every two minutes. After an hour of rest, hand ergometer test was carried out with the same intensity and forced vital capacity and expiratory volume were measured by spirometry before and immediately after the ergometers. Data were analyzed using two-way analysis of variance, ANOVA, paired t test  and Tukey post hoc test at P<0.05. The results showed that age and protocol type had a significant effect on FVC and FEV1, that is to say FVC level was significantly lower in young subjects than the elderly and middle-aged subjects (P<0.05) and it was higher in the middle-aged than the elderly (P<0.05) following leg and hand ergometers. In addition, FEV1 was significantly higher in the middle-aged than the elderly following the ergometers (P<0.05) and lower in the young subjects than the elderly and middle-aged (P<0.05). The interactive effect of age and exercise protocol type on respiratory parameters was determined. In addition, it became clear that the leg ergometer increased FVC in young subjects and improved FEV1 in all three age groups, but hand ergometer improved only FEV1 in young and middle-aged subjects.
