the effect of different age groups and protocol type (leg ergometer against arm ergometer) on respiratory function in men

the aim of this study was to investigate the effect of different age groups and protocol type on respiratory function in men following a progressive aerobic exercise protocol. 37 healthy males (mean age of 12.7±1.7, 34.3±4.9,52±5.7 yr) were selected voluntarily. 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
