The purpose of this study was the effects of resistance training on some pulmonary indexes, body composition, body fat distribution and VO2max in thin and fat men. There are several reports on the association between body mass index (BMI) and pulmonary indexes. The method of this study was semi - experimental. Study's approach was of pre-tested and post-tested with the control group. Statistical sample of this research, includes 200 of male masters and personnel of Behbahan Azad University with average between 35 to 45 ages. In this study, the examinees were categorized by simple random selection into experimental groups of less than 20 and more than 25 BMI. Before resistance exercising, we took pre-test and post-tested of pulmonary indices(FEV1, FVC), body mass index, body fat distribution and VO2max from each group, and obtained data are analyzed by variance analysis, in the meantime the level of significance in this research is alpha <= 0/05, and analyzing of data is done by spss software. The result of this study has shown that resistance training has affected on pulmonary indices in two groups and they had significant difference with control group P <= 0/05. This training caused increase on BMI in thin group and it has significant difference with control group P <= 0/05. There are many studies have shown the effect of resistance training on pulmonary indices, BMI. We can see a positive significant associated between VO2max and pulmonary indices and a negative significant associated between pulmonary indices and BMI, body fat distribution with increase in once caused decrease in another.
