PURPOSE This study investigated the associations between physical fitness and fall efficacy with thigh circumference in elderly women with osteopenia/osteoporosis. METHODS A total of 166 female participants aged 76.3±5.0 years with –1.0≥T-score of femur neck bone mineral density were voluntarily recruited from local community centers. The participants were classified as low 25%, middle 50%, and high 25% groups based on their thigh circumference. Physical fitness measurements, including strength, flexibility, aerobic endurance, and balance were measured with a standardized protocol. The Korean version of the fall efficacy scale (K-FES) was used to assess fall efficacy. Logistic regression analysis was used to estimate odd ratio (OR) of poor physical fitness and low fall efficacy according to thigh circumference levels. RESULTS In terms of physical fitness, the middle 50% group (OR=0.430, 95% CI=0.194-0.953) and high 25% group (OR=0.129, 95% CI=0.049-0.343) had significantly higher linear trend for poor physical fitness compared to the low 25% group (reference), (p<0.001). In fall efficacy, the middle 50% group (OR=0.279, 95% CI=0.119-0.656) and high 25% group (OR=0.100, 95% CI=0.036-0.275) had significantly higher linear trend for low fall efficacy compared to the low 25% group (reference) (p<0.001). CONCLUSIONS The current findings suggest that maintaining high thigh circumference via regular physical activity and diet may contribute to attenuation of decreased risk for poor physical fitness and low fall efficacy in elderly women with osteopenia/osteoporosis.
Purpose The purpose of this study was to examine the effects of 16 weeks’ combined exercise training on insulin resistance, inflammatory markers, oxidative stress, leukocyte telomere length, body composition, and daily living fitness in elderly women with type 2 diabetes mellitus (DM). Methods Twenty-eight participants were randomly assigned into one of two groups, i.e., exercise training group (EX: n=14) and control group (CON: n=14). Subjects in EX participated in 3 sessions of 60 min-combined exercise for 16 weeks, whereas subjects in CON were asked to maintain their normal life pattern during the same period. The variables regarding insulin resistance, inflammatory markers, oxidative stress, leukocyte telomere length, body composition, and daily living fitness were measured and compared between two groups as well as between pre-post test utilizing a repeated two-way ANOVA. Results Main results were as follows: 1) Fasting plasma insulin and HOMA-IR tended to decrease in EX, whereas increased significantly in CON. 2) IL-6, TNF-α, hs-CRP decreased in EX, but the changes were not statistically significant. 3) MDA increased significantly and GPx decreased significantly in both EX and CON. 4) Leukocyte telomere length increased significantly in EX. 5) Fat-free mass increased in EX, whereas fat mass and percent body fat decreased significantly in EX. 6) Arm curl, chair stand, sit & reach, tandem test, 10m walking speed, and up & go improved significantly in EX. Conclusion It was concluded that the combined exercise for 16 weeks had a positive effect on improving insulin resistance, increasing leukocyte telomere length, as well as enhancing body composition and daily living fitness in elderly women with type 2 diabetes.

[Purpose] The present study attempted to verify the effectiveness of an early childhood physical health improvement program (subsequently in the present study, KICCE Early Childhood Health Improvement Program) developed in Korea by modifying and improving the Mission-X: Train Like an Astronaut program developed by NASA to be suitable for children of ages 4 and 5. [Methods] The subjects in the study were 679 children at 7 facilities in Seongnam city, Osan city, and Yongin city, of which 4 were daycares and 3 were kindergartens. The participant group consisted of 339 children, and the control group consisted of 340 children. The program consisted of total 24 activities 3 times a week over 8 weeks, of which 8 activities were related to nutrition and 16 activities were related to physical activity, and in the 9th and 10th weeks, the 16 physical activities were reconfigured and performed 3 times a week. Physical parameters and related fitness parameters were measured before and after the program, and an ANCOVA analysis was performed in which descriptive statistics and scores before the program were the covariate variables. [Results] The results show that first, growth statuses of participant children were in the upper middle section of the distribution, and second, of the 6 fitness developments, flexibility, balance, and quickness were improved, and in most areas, boys and below-normal-BMI group showed beneficial effects. [Conclusion] Thus, KICCE Early Childhood Health Improvement Program is conclusively proven to be effective for early-childhood physical development.
Recently, there have been diverse types of physical activities supported by government policy in S. Korea. However, these activities may not be effective if they do not reach to moderate to vigorous level. This study designed school physical education system based on SPARK program, which include traditional physical education, sports club based physical activity, after school physical activity, and Saturday physical activity, to evaluate its effectiveness associated with physical fitness and empirical meanings of physical activity. This study employed a mixed method research paradigm for better understanding. Among various mixed method paradigm stances, this study employed "blending strategy" for complementary analysis. First of all, the effectiveness in health condition was evaluated by quantitative data. Specifically, physical fitness and lifestyle were analyzed by Helmas, IPAQ, and Accelerometer respectively. Second, empirical meanings of physical activity were analyzed by both Photovoice and in-depth interview which are qualitative research method. The result of this study first showed that a specially designed school physical activity program based on the SPARK contributed to improve students' physical fitness and lifestyle as well, however, there were important differences between male and female students. Second, physical achievement, alteration of spatiotemporal meaning, and change of societal relationship emerged as important themes. Further, these themes showed that they played an important role to maintain students' motivation in physical activity and consequently physical activity promotion was invigorated in school. Based on these results, we synthesized investment factors and process factors and outcome factors respectively. Finally, we suggested alternative teaching methods and suggestions for following research to overcome gender issues.
Impact of 9-week strength training of racing cyclist candidate during training camp on body composition, racing cyclist specific fitness, and racing cycle performance was examined. Two by two (cyclist experience, y/n and strength training (ST) participation, y/n) experiment design was employed. A total of 20 candidates participated and divided evenly into four groups; 1) experienced cyclist participating ST (CST), 2) non-experience cyclist participating ST (nCST), 3) experienced cyclist no participating ST (CnST), and 4) non-experience cyclist no participating ST (nCnST). Two programs were introduced; 1) non ST containing, pre-existing program emphasizing on sprint and acceleration training and 2) new-program containing ST and sprint and acceleration training. CST and nCST participated the latter program. Before and after the 9-week training, body composition, racing cyclist specific fitness, and racing cycle performance was tested. After 9 weeks, all groups decreased body weight(p<0.05), body fat content(p<0.05), body mass index, and CST and nCST increased lean body mass(p<0.05). Muscular strength measures such as grip strength, low back strength, 1RM of bench press, 1RM of squat, and anaerobic capacity improved after 9 weeks in all groups(p<0.05). The magnitude of changes was greater in order of CST, nCST, CnST, nCnST. Time trial of 200 meter sprint was faster after 9 weeks in all groups except CnST while 500 meter sprint was improved only in nCnST(p<0.05). After 9 weeks, regardless of previous cyclist experience, those who participated in ST ranked high places at racing cycle competition. Both training programs for the candidates improved body composition and racing cyclist specific fitness. When strength training was added to pre-existing training program emphasized on sprint and acceleration, the racing cycle performance was enhanced. Strength training for racing cyclist is highly recommended to improve their racing performance.
Purpose The purpose of this study was to examine the effects of parents’ involved dance-sports program on a physical activity level and a fitness of children with a developmental disability and on their parents’ perception. Methods The participants were seven children with a developmental disability ranged between 8 and 16 years and seven parents of them participating in the dance-sports program during 90 minutes, 3 times per week for 8 weeks. The quantitative data (i.e., the physical activity level, the physical fitness, and the questionnaire) were collected before and after the intervention. Results The results showed that there was statistically significant difference of the parents’ perception on children’s participation in a physical activity [F=5.63, P<.04]. Although the experimental group showed increase trend, whereas the control group showed decrease trend, there was no statistically significant difference of the physical activity level and the physical fitness of the children with development disabilities. Conclusions Parent participated dance sports program seems to be effective on parents’ perception on children’s participation in a physical activity, physical activity level and the physical fitness of the children with a development disability in experimental group.
When the long-awaited KSME in PESS was established in 1998, KSME faced a turning point in its growth. Following the changes in both quality and quantity of the society's researches since its establishment and seeking for future themes is important for the society. This research analyzed the society's research trend using mainly the Korean Journal of ME in PESS. Then, by examining the physical fitness test, it proposed possible future themes for the KSME. This research also looked into the American Kinesmetrics’ contribution to Kinesiology, its research trend and future researches The KSME's recent researches show refined quality, diversified themes and reinforcements in practical researches. Regarding the themes, the reliability and validity of tests became predominant, sports analysis and physical activity emerged, and interest in measurement and evaluation in school PE was low. Possible research themes in the future are measurement and evaluation in school PE, game analysis and sport big data. The recent interest of the American Kinesmetrics was the cross validation of criterion-referenced physical fitness cut-off score, the validation of the guideline for physical activity, and the relationship between sedentary behavior and health. Possible future research themes of the American Kinesmetrics were the refinement of test methods, the effectiveness of the physical fitness test award system, and the application of the ubiquitous wearable technology.
