The purpose of this study investigated on exercise type for cardiovascular function and bone mineral density in middle aged womens. 20 housewives selected as subject and then divided in two group; The health+swim group with 10 women, swim group with 10 women, total 20 women. The results were as follows; 1. Cardiovascular function were Significant different was appeared on restHR(p<.05) in health+swim group higher than swim group, but Non significant different was appeared on HRmax, ^(·)VO₂/㎏, ^(·)VEmax in each group. 2. Bone mineral density were Significant different was appeared on spine(p<.001), lumbar(p<.001), ribs(p<.001), pelvis(p<.0001), total BMD(p<.0001) in health+swim group higher than swim group. 3. Cardiovascular function and Bone mineral density's Correlation coefficient of variables were retHR and spine(r=-0.51), ribs(r=-0.81), total BMD(r=-0.68) have significant negative relation, ^(·)VEmax and lumbar(r=0.52), total BMD(r=0.45) have significant positive relation

The purpose of this study was to use the meta-analytic approach to examine the effects of exercise on blood lipid profile and hormone variables. A total of effect sizes(ES) representing subjects from 42 studies met the criteria for inclusion. All doctor dissertation studies published after 1900, in Korea, were reviewed for inclusion from training search. Studies had to be prospective intervention trials, randomized or not, evaluating the effectiveness of an exercise program of any duration. frequency, time. Effect sizes(ES) were calculated for each variables and site measured in every eligible study according to Hedges and Olkin. Significant difference were analyzed, using an Fisher's Z test. Statistical significance was accepted at the p<0.05 level. The results through the statistical analysis of variables were as follow. 1. The total cholesterol level was significant ES changes following exercise duration was significant difference for >8wk(ES=-0.457, p=0.0015) but not ?8wk. The exercise frequency showed statistically significant changes for >3(ES= -0.292. p=0.0149) but not 3?. The exercise time showed significant changes for >30min(ES= 0.435, p=0.0042) but not ?30min. 2. The TG level was significant ES changes following exercise duration was significant difference for >8wk(ES=-0.328, p=0.0184) but not ?8wk. The exercise frequency showed statistically no significant changes for >3 and ?3. The exercise time showed significant changes for >30min(ES=-0.240, p=0.0484) but not ?30min. 3. The LDL-cholesterol level was significant ES changes following exercise duration was significant difference for >8wk (ES=-0.587, p=0.0001) and ?8wk(ES=0.459, p=0.0385). The exercise frequency showed statistically significant changes for ?3(ES=-0.630, p=0.0413)) and <3 (ES=-0.320, p=0.0117). The exercise time showed significant changes for >30min(ES=-0.548, p=0.0007) but not ?30min. 4. The HDL-cholesterol level was significant ES changes following exercise duration was significant difference for >8wk(ES=0.795, p=0.0000) and ?8wk(ES=0.882, p=0.0013). The exercise frequency showed statistically significant changes for ?3(ES=0.633, p=0.0376) and >3(ES=0.837, p=0.0000). The exercise time showed significant changes for >30min(ES=0.711, p=0.0000) and ?30min(ES=1.016, p=0.0000).
