The purpose of this study was to determine the effects of step-band exercise on body composition and SFT(Senior Fitness Test) in the Young-Old(YOA, n=13) and the Old-Old Adults(OOA, n=19). The step-band exercise needed equipments-a steeper and a thera band was performed for 90 minutes, 2 times a week, for 16-week. Body composition, SFT were measured before and after the step-band exercise. To analyze effects of exercise results, Two-way repeated measures ANOVA was carried out by each variable. The statistical significance level was set for α=.05. The results of this study are as follows: First, Body weight, BMI and WHR significantly were decreased in all group after 16-week exercise(p<.05). BFM(body fat mass), %BF were significantly decreased in OOA after 16-week exercise(p<.05). But MM(muscle mass) was statistically increased in OOA(p<.05). Second, there was no significant an interaction related to SFT between a time and a group and the step-band exercise improved all measurements of SFT in all groups(p<.05). There was no significant differences between two groups(p<.05) in Arm curl, 2-Min step, back stretch area. These results suggest that step-band exercise improves body composition and SFT in young- and old-old adults. In this study, the step-band exercise was especially more effective to the OOA than the YOA.

The aim of this study is to compare and analyze the body composition, leg strength and cardiovascular variable for the elderly who are in residential aged care facilities according to sex and age. A total of sixty-nine subjects between 65 to 85 who inhabit in Silver Tower, fee charging facilities for the elderly, were invited to participate. Four groups were formed; a young-old men Group (YMG, n= 31), a young-old woman Group (YWG , n = 22), an old-old men Group (OMG, n= 8). Variables of Body composition (Ht, Wt, BMW, BF, BF%, BMI)were measured through Bioelectrical Impedance Analysis(BIA). Variables of leg strength (60%PTFx, 60%PTEt, 180%PTFx, 180%PTEt) were measured by isokineic devices Cybex 6000. Cardiovascular Variables (RHR, RSBP, RDBP, MHR, MSBP, MDBP) were measured through sub-maximal test applied by Modified Bruce Protocol. All data were expressed by using One-way ANOVA in order to compare between 4 groups. Significance level(a) was 0.05. Ht and BMW of body composition variables between groups showed that YMG and OMG were high. There was statistical significance according to sex (p<.05). BF and BF% from comparison between groups turned up higher for YWG and OWG. There was statistical significance according to sex as well (p<.05). BMI from comparison between groups turned up higher at YWG. There was statistical significance according to sex and age (p<.05). All data of cardiovascular variables showed that there was not statistical significance according to sex and age. 60%PTFx and 60%PTEt of all leg strength variables between groups showed that YMG and OMG were high. There was statistical significance according to sex (p<.05). It showed that there was no statistical significance in 60%PTFx and 60%PTEt of all leg strength variables between groups. In conclusion, it is expected that body composition and leg strength variables for the elderly are so different according to sex and age that the life expectancy of the elderly will increase more. The more detailed studies are needed in future.

The purpose of this study is: (1) to testify the significant differences of body composition factors depending on sex and age; and (2) to investigate the correlation, if any, of the two different methods used for the research. The two methods are STM(the skinfold thickness method) and BIA(the bioelectrical impedance analysis), the most popular techniques currently used in the field. The representative sample group consists of 172 middle school students and 210 high school students, who live in Seoul and whose age distribution covers from thirteen to eighteen. The research based its comparison and analysis on the basic physical constitution factors, percent body fat, body fat mass, and fat free mass, and yielded the following results: First, the height and weight of the sample group increased in proportion to their ages, regardless of sex. Second, in case of the body fat mass, the average rate of the female sample group was higher than that of the male ones, and increased moderately in proportion to age. Both of the methods produced the significant differences depending on age and sex(p<.05). Third, the female sample group contained more body fat mass than the male counterpart, and the body fat mass increased in proportion to age. Both of the methods produced the significant differences depending on age and sex(p<.05). Fourth, the male sample group contained more fat free mass than the female counterpart. The fat free mass increased in proportion to age, and that conspicuously in case of the male sample group. Both of the methods produced the significant differences depending on age and sex(p <.05). Fifth, the outcome of the percent body fat, body fat mass, and fat free mass, resulted from STM and BIA proved distinct correlation between the two methods(r=.86,.90,.95). In sum, adolescence is the most prominent period in terms of the physical maturation and hormone secretion. The period experiences the remarkable shift in the physical constitution and articulates distinct differences of the body composition factors. Accordingly, the period deserves critical attention and requires systematic analysis and evaluation. The two methods have legitimated their usage as reliable techniques, with the visible presence of a substantial body of work engaged with the techniques. My study is designed to be part of the attempt to articulate their credibility as a set of techniques in analyzing and evaluating the body composition factors.
