In pre-test and post-test. the circumferenc, hypodermatic fat and mascular endurance of abdoment were
measured. The independent and dependent T tests and SPSS Win95 software were used for statistical analysis which showed that Although the intelVal and steady trainings resulted in an increase in mascular endurance of abdomen, the
steady training had more effect. The intelVal and steady training didn't result in a reduction in circumference of abdomen. But this type of training resulted in a
reduction in the local fat in abdomen and specially, the intelVal training had
