The study aims to identify the research trend centered on keywords most frequently used in research on elderly citizens with the topic of exercise based on domestic academic journals published. Keyword network analysis based on network algorithm was used. For the network text analysis, the SNA package of the R program(version 3.5.3) was adopted to extract major keywords based on the frequency and to identify the connectivity between them. As a result, it turned out that the number of research on senior exercise has been steadily increasing since 1995. Major keywords used were: “elderly”-562 times(28.3%), “elderly women”-377 times(19.0%), “exercise”-281 times(14.1%), “body composition”-159 times(8.0%), “combine exercise”- 143 times(7.2%), “physical fitness”-122 times(6.1%), “balance”-107 times(5.4%), “depression”- 99 times(5.0%), “lipid”-99 times(5.0%), and “resistance exercise”-88 times(4.4%). Also, the result was reanalyzed based on the four major diseases seniors develop gotten from the keyword network analysis. Among the 331 thesis papers on obesity, 48.0% included the keyword “body composition,” 6.9% included “BMI,” 4.2% included “body fat,” and 3.9% included “% body fat.” Also, among the 285 papers on falls, 26.7% included “gait ability,” 24.2% included “fall,” and 18.6% included “BMD.” Among the 218 papers on depression, 45.4% included the keyword “depression,” 33.9% included “QOL,” 20.64% included “self-efficacy,” 9.2% included “self-esteem,” and 7.34% included “life satisfaction.” Meanwhile, among 126 thesis papers on dementia, 17.5% included the keyword “cognitive function,” 13.5% included “BDNF,” and 6.3% included “MMSE-K”. This result of keyword network analysis will be able to serve as the primary data for researchers studying the exercise of aged citizens when establishing an academic system. Also, by emphasizing the importance of elderly workouts, it will be able to work as a bridgehead for policy support in a bid to make the exercising habit a part of their daily life, and ultimately contribute to the development of physical training.

The purpose of this study was to compare risk factors of cardiovascular disease (CVD) to menopause and premenopausal women, and to examine the effects of aerobic capacity on CVD risk factors. The subjects were 106 middle-aged women under 40~60 years old and classified as postmenopausal women (53.1±3.1 years, n=49) and premenopausal women (45.5±3.7 years, n=57) in a questionnaire. Body composition, aerobic capacity (VO2max) and CVD risk factors (blood pressure, blood lipid, glucose) were measured as measurement variables. The correlation coefficient (r) was calculated by Pearson's product correlation. As a result, menopause women were significantly higher in body mass index, body fat, %body fat, SBP, DBP, TC, LDL-C and glucose than women before menopause (p<.05). VO2max was significantly higher for premenopausal women (24.9±5.0 mL/kg/min) than for menopause women (23.0±4.0 mL/kg/min) (p<.05). In addition, there were significant correlations between VO2max, body mass index (r= -.330), %body fat (r= -.451) and glucose (r= -.264) (p<.05). In conclusion, body composition, blood pressure, blood lipid and glucose are the major CVD risk factors affected by menopause, and CVD prevention is needed before menopause due to correlation with aerobic capacity.

The study aims to identify research trend centered on keywords most frequently used in research on youth obesity with the topic of exercise during the recent 10 years (from 2000 to 2019) based on domestic academic journals published in the RISS. Keyword network analysis based on network algorithm was used. For the network text analysis, the SNA package of the R program (version 3.5.3) was adopted to extract major keywords based on frequency and to identify the connectivity between them.
First, in regards to “Physical Education as Liberal Education” research with the topic of exercise, physical education (52 times), class satisfaction (38 times) and general physical education (24 times) had high centrality measures.
Second, a total of 308 thesis papers were written between 2010 and 2019 with the keyword “Physical Education as Liberal Education.” As the research trend was compared based on the keywords used, the number of research decreased in 2011 and 2017, but it showed an upward trend in general. This phenomenon is considered to have occurred due to the change in the liberal education curriculum before and after 2010.
Third, as the centrality of research trends that have the keyword “physical education as liberal education” was analyzed, “physical education”, “class satisfaction”, “intention to continue exercise”, “participation motivation”, and “fun factor” were frequently found. While these keywords are related to class satisfaction, the background is considered to be due to the tendency that prioritizes class satisfaction when it comes to physical education.
As a result, it is found that Korea's physical education classes in universities are mainly conducted in a form that aims to improve class satisfaction of students and instructors rather than focusing on the main value of boosting health, sociality, and autonomy through physical activities. However, an important key to remember is that it is important to build up a foundation for university students to form an exercise habit while improving physical strength and cultivate it for the rest of their life by focusing on the main role of physical education. Therefore, it is considered that a multi-directional approach toward the diversification and activation of physical education as liberal education is needed.

The subjects of this study were elderly women under 65-85 years of age who were recruited as publicity flyers for the Elderly Welfare Center in K City D. For the cognitive function, the Korean Mini-Mental State Examination (MMSE-K) and the Falls efficacy scale were used for the Korean falls efficacy scale (FES-K). LFA was developed by converting the general score of daily life fitness factors into an age scale. For statistical processing, a paired t-test was conducted to examine the difference between each variable before and after GO-SE. The statistical significance level was 5%. Before and after GO-SE, there were significant differences in body weight and lean body mass, 5 chairs, standing time, and 5 m maximum walking. At the LFA, which converted the overall score of each fitness factor into an age scale, it was significantly lower than before exercise (77.0±5.7 yrs) and after 16 weeks (74.9±2.9 yrs) (p<.05). Cognitive function was significantly higher in MMSE-K before exercise from 26.8±1.5 to 29.0±1.3 after 16 weeks, and fall efficacy was significantly higher from 2.9±0.6 to 3.2±0.5 (p<.05). The conclusion is that the new GO-SE, which combines both cognitive exercise and easy-to-understand exercise tasks, improves cognitive function as well as falls prevention by improving the balance ability and fitness for the lower extremities of the elderly women.

The purpose of this study was to investigate the characteristics of the warping path on gait patterns using the DTW algorithm. Participants in this study were consist of 20's age of 10males and 10 females. Gait data obtained by a 3D motion analysis system analyzed using the DTW program made by Matlab's functions. The analysis was performed 120 times including normal walking and abnormal walking. The length of the warping path relative to the reference sequences, and deviations was analyzed for the warping path calculated by the DTW program. The statistical method used in this study was a correlation, independent t-test, one-way ANOVA, and regression. The statistical significance level was α=.05. In this study, the correlation coefficient of Pearson was r=.816 between the warping path length and the deviation, and this relationship was verified by regression analysis. The statistically significant difference between normal walking and abnormal walking appeared in the warping path length and in the deviation. The analysis according to walking phases showed a statistically significant defference between the support phase and the swing phase. In conclusion, if the length of the warping path is greater than about 127% compared to the diagonal length between two sequences, normal walking can be suspected, and if the mean of the warping path length deviations is greater than about 5.8, normal walking can be suspected also.

Optimal protein supplementation is an essential consideration for maximizing adaptive responses and recovery ability from physical and physiological stress of high intensity resistance training. There are several timings of consuming protein supplements based on nutrient timing system such as pre-exercise (energy phase), post-exercise (anabolic phase), and pre-sleep (growth or adaptation phase). However, it is not yet established which protein timing is the most effective way to maximize the adaptive responses to resistance training. Thus, this review was carried out to suggest an optimal timing of protein supplementation by discussing the effects of each timing of protein intake (pre-exercise, post-exercise, both post-exercise and before sleep, both before and after exercise) on muscle adaptations to resistance training. Also, we provide scientific information to develop practical strategies of protein supplementation on prolonged resistance training by combining the results of previous studies. We expect our review to offer relevant information for developing a sport-specific optimal timing of protein ingestion for strength/power athletes.
