2. Methods
The method of this study was semi experimental. Statistical sample of this research, includes 200 of male masters
-
tested with the control group. the examiners were classified to experimental group in which participated in aerobics
exercising and then on base of body mass index classified (,20-25,and more than 25 BMI)and we selected a group as
control to comparison the effect of aerobics training on experimental group. and they took training 8 weeks , we
took pre-test and post-tested of pulmonary indices( FEV1 ,FVC),body mass index , body fat distribution and
VO2max from each group. In this study, the examiners were categorized by simple random selection into
experimental groups of (between20-25, and more than 25 BMI.), in the meantime the level of significance in this
0/05, and analyzing of data is done by spss software. The magnitude of the pre- and post training
changes in the two study groups was compared through the use of a one-way analysis of variance (ANOVA) (group,
training effect), with repeated measures for the second factor (training effect). A value of p < 0.05 was considered
statistically significant
The 8-wk training program included a period of aerobic training that was supplemented with a 45-min period of
relaxation and breathing exercises for the AERO group. the breathing exercises During the training sessions, objects
were closely supervised by a trainer . The aerobic training consisted of run on the treadmill for 30 min in each of
three weekly sessions. We aimed at high-intensity training, and the work rate corresponding to 70% of the peak work
rate achieved during the baseline incremental exercise test was selected as the target training intensity..
