摘要：The aim of present study was to investigate comparison of aerobic training on blood gases. Thirty six non athlete and sixteen athlete high school girls (age 14-17, weight 48-55, height 159-166) were randomly located into three groups. Group1: Control group and non-athlete without aerobic training (n=16), Group2: non-athlete with aerobic training (n=16) and Group3: athlete with aerobic training (n=16). Gruop2,3 participated in an 8-weeks aerobic training at the pulse rate of 65%-75% of Max Heart Rate and control group was asked to maintain their activity and eating habits during the investigation period. To determine rate of blood gases (PO2, PCO2, PH, and HCO3-) changes, of all subjects were measured via blood sampling. In pre-Test and immediately after last aerobic training session, all blood samples were analyzed via Laboratory Gas Analyzer. Data was analyzed by descriptive statistic and T-test at the significant level of P<0.05 and following results were concluded: blood gasses such as PO2,PCO2,PH except HCO3-were changed after last session in group 2,3 but there were significant differences in PH,PCO2,PO2 between second and third groups that it was not seen in HCO3-.
