[Purpose] The purpose of this study was to provide the physiological characteristics of female adults in their 30s by comparing the body composition and the maximal strength of the knee extension and flexion and bilateral ratio and ipsilateral ratio(H/Q: Hamstring and Quadriceps ratio) depending on age. [Methods] Body composition was measured by Hv-ps 7681(GE medical systems Lunar, USA). Isokinetic lower limb muscular strength was measured by Isomed2000(D&R Ferstl GMBH, Germany). 92 volunteers who were chosen by our selection criteria agreed to participate in our study. The participants were divided into three groups depending on age and classified as female adults in twenties(n=30), in thirties(n=34), in forties(n=28). To evaluate differences according to age, One-way ANOVA was used. [Results] The result in the test for female adults is as follows. In body composition, there were significant differences in lean mass, bone mineral density in the legs area among groups(p<.05). In isokinetic test, there were significant differences in muscular strength among groups in extensor of knee(p<.05). [Conclusion] The finding revealed that strength training based on the characteristics depending on age is required and ipsilateral ratio needs to be improved.
The purpose of this research is to provide the information about sports injury by surveying and analyzing a result, and to lead analytic and scientific training among the subjects being elite summer sport athletes. All sports injuries are recorded on injury report form and the following results were obtained. In Cycle sport, the prevalence of injuries of the low back, knees were highest. and In Table tennis sport, the prevalence of injuries of the ankle was highest due to the chronic fatigue. The prevalence of injuries of the shoulder, low back were highest due to the overuse of joints. In Badminton sport, the prevalence of injuries of low back, knees, ankles were highest by overtraining. In Gymnastics, the prevalence of injuries of the low back, knees, ankles were highest. In Archery sport, there is a lot of injuries to the shoulder and neck. In Weight lifting sport, the prevalence of injuries of the low back, knees, and ankles were highest. In Golf sport, the prevalence of injuries of knees, low back were highest. In Hockey sport, the prevalence of injuries of ankles, knees, low back were highest. In Boxing sport, the prevalence of injuries of hands, shoulder, the low back were highest, In Judo sport, there are overall damage occurred in parts of the whole body, but the prevalence of injuries of ankles, knees, low back were highest. In Fencing sport, the prevalence of injuries of the low back, knees were highest. In Wrestling sport, although there is a difference slightly depending on freestyle and Greco-Roman, but the prevalence of injuries of knees, ankles, low back were highest. In Handball sport, the prevalence of injuries of ankles, knees were highest. In Taekwondo, the prevalence of injuries of ankles, knees, feet were highest.
