The purpose of this study was to evaluate the connection betwene attendance and the effect on the bod ycomposition, physical fitness and cardiovascular risk of female adults who attend the 12 week-combined exerciseprogram. The total 19 participants who involved in a public health center in G city, were divided intoactive group(12 participants) at over 70 rate of participationa nd non-active group(7 participants) at under 30rate of participation, and they got the combined exercise continaing aerobic ladder and weight training for 1 2weeks; 3 times per week as HRmax 60~85% and 60 minutes per time. All the statistics were calculated by SPSSVer 18.0 (p<0.05). Active group`s waist measurement was more decreased than non-active group`s one in theinteraction of groups and periods, significantly. Both groups` body fat were decreased and only active group`s waist and hip measurements were decreased in the comparison of each groups. In the part of physical fitness, both groups` the number of Sitting Trunk Flexion and Push-up wree increased but only in the active group , back strength, leg Extension Power and the number of sit-up were increased, significantly. Non-active group`s T-C, TG and LDL-C were more decreased than active group`s on ein the interaction of groups and period, significantly. FFA of both groups were decreased in the compasroi n of each groups, significantly. Eventually, after taking this exercise program for 12 weeks, the waist measurement of active group was decreased butT-C, TG and LDL-C of non-active group were more decreased than active group. As a result, the active groupat high rate of participation is more effective for body composition, physical fitness and cardiovascular risk thanthe other group. It means frequent exercise is more essentialF. urther more, participation of the program fo r12 weeks is important, but it`s more important to practice regular exercise even irregular one.
