The purpose of this study is to analyze a maximal aerobic power(MAP) and % fat of the urban female. The subjects are 73 urban females who were devided into three groups(27 young femeles, 35 middle females, and 11 old age females) I measured Margaria bench stepping, VO_2 max calculated by Margaria's estimation expression, and % fat was calculated by using Nagamine's estimation expresstion. Therefore, The results of this study is to be compared to the cross sectional analysis among three groups. The results are as follows : 1. 「MAP」 Young female groups MAP was 41.4±13.99㎖/㎏·min, middle age females 39.2±13.95㎖/㎏·min, and old age females, 38.2±10.4㎖/㎏·min. This data showed that 3 groups were in fitness. 2. 「% Fat」 %fat in young female groups % fat was 31.4±5.46%, middle age females, 32.5±8.09%, and old age females, 31.3±6.92%. According to the results, 3 groups have no statistical significance(P>.05). These data showed that three groups were over weight(obesity).

The purpose of this study is to analyze the effects of response time (RT) and the speed of movement(SM) through 「SQT」 Programme by the light-stimulus simulation trainer as the examined in tennis players of KNU. The method of the present investigation was a longitudinal study. During the 5 weeks of experiment period, hard simulator training was regularly reinforced once for 20∼30 minutes a day. The RT and the SM of pre-test group and post-test group were measured after the subjects reposed enough rest. The results obtained are as follows: ⅰ. The RT was reduced as 144msec, 18msec, 60msec(p<.01, p<.001), 108msec, 112msec(p<.01) for pre-test/post-test of SRT and CRT. The difference of RT between the pre-test group and post-test group was statistically significant. ⅱ. The SM was reduce to mean values: ⅰ) The V-SM was reduced 167msec, 208msec, 189msec, 229msec, 226msec, 161msec 210msec 134msec, 114msec, 93msec, 108msec, 43msec, 200msec (p<.01, p<.001) for pre-test/post-test. ⅱ) S-D SM was reduced as 242msec, 220msec, 115msec, 42msec (p<.05, p<.001) for pre-test/post-test. ⅲ) R-D SM was reduced as 252msec, 159msec, 541msec, 499msec (p<.001) for pre-test/post-test. ⅳ) R-D SM was reduced as 325msec, 230msec, 190msec, 257msec, 268msec, 208msec, 670msec, 510msec (p<.001) for pre-test/post-test. The difference of V-Sm, S-D SM, R-D SM, and R-S SM between the post-test group and pre-test group was statistically significant. As mentioned above, a considerable significance is revealed between pre-test group and post-test group, especially an effective difference in comparison with pre-test. Therefore, an execution of intensive light stimuli simulation training program according to 「SQT」 is much desirable for the racket exercise.
