The purpose of this study was to examine the effect of balance training on metabolic syndrome indicators and functional fitness. For this purpose, a 12-week balance training was conducted for 16 elderly women who usually complain of back and shoulder pain. In addition, of the 16 subjects, 8 were classified into the exercise group and 8 into the control group, and the effectiveness of the training program was verified. As a result of examining the metabolic syndrome index and functional fitness before and after 12 weeks of balance training, the following results were obtained. First, a significant interaction was shown in the metabolic syndrome index before and after 12 weeks of balance training. Second, there was a significant interaction in functional fitness before and after 12 weeks of balance training. This confirmed that balance training had a positive effect on functional fitness along with positive changes in metabolic syndrome in elderly women. In the future, it is necessary to clarify the effect of balance training through the expansion of the training period and measurement variables.

국내의 자동차 정비 훈련 교육 현장에는 훈련교사가 빠르게 발전되고 있는 자동차 정비 기술 수준에 맞춰 교육하는데 어려움이 있다. 이 같은 어려움을 해결하기 위한 이-트레이닝(E-training) 시스템은 체험형 훈련이 가능하면서도 높은 학습 효과를 가져올 것이라 기대되고 있다. 자동차 정비 훈련을 위한 이-트레이닝 시스템은 훈련교사가 자동차 고장 항목을 설정하면, 훈련생이 고장 진단을 위한 다양한 시도를 하여 고장을 인지하고, 그에 따른 조치를 통해 주어진 문제를 해결함으로써 학습효과가 높아질 것이라 기대되는 시스템이다. 하지만 이-트레이닝 시스템은 이미 설정되어 있는 시나리오에 따른 일방적인 교육, 학습자에 대한 지속적인 관리의 어려움, 학습자의 행동을 추론하여 정확한 결과를 도출해내기가 어렵다는 한계가 있다. 본 논문에서는 이-트레이닝 시스템의 문제점을 해결하기 위한 방법으로 자동차 정비를 위한 자동차 몸체, 엔진, 정비 도구에 대한 온톨로지를 구축하고 추론하여 효과적인 자동차 정비 훈련 교육이 될 수 있도록 하는 방법을 제안하고자 한다.

Pressurization walk training (PWT) with blood flow occlusion has been investigated with regard to muscle hypertrophy and physical fitness function in athletes and healthy people. However, the cardiorespiratory and cardiovascular responses of obese people to PWT are unknown. Thus, we investigated the effects of PWT on body composition (Weight, FM, LBM, %fat, BMI), cardiovascular responses (HR, SV, CO, TVC), and cardiorespiratory responses ($VO_2max$, VEmax, HRmax) in middle-aged obese women. They participated in walk training with (n=15) blood flow occlusion and cross-sectional areas of the quadriceps on both legs. Five sets of 3-min walking (5.5 km/h at 5% grade) and 1-min resting were performed twice a day, 5 days/week for 3 weeks. The results showed that the LBM was significantly increased, and decreased body weight of reducing FM, %bodyfat in PWT ($p$<0.05). For the cardiovascular response, SBP and TPR were significantly decreased ($p$<0.05), and CO increased ($p$<0.05). In addition, the $VO_2max$ and VEmax were improved through PWT. Therefore, this study suggests that the presence of obesity in middle-aged women may result in body composition, cardiorespiratory, and cardiovascular responses caused by PWT.

The purpose of this study was to investigate the effect of 12 weeks of combined training (aerobic/anaerobic training and space perception training) on changes in body composition (weight, % body fat, % muscle mass, BMI, WHR) and cardiorespiratory fitness according to the ACE gene polymorphism (II: 7 men, ID: 8 men, DD: 6 men) in 21 senior Korea Air Force Academy cadets. The results of this study were as follows: body composition factors among ACE gene polymorphism groups and between pre-/post-training in all groups were not statistically significant. Cardiorespiratory fitness of the II and ID groups was significantly lower after training (p<0.05). However, there was no statistically significant difference between pre-/post-training in the DD. In conclusion, this study suggests that cardiorespiratory fitness response to compound training may be affected by ACE genotypes.

In this paper, we propose the relationship between the expectation of home training, exercise commitment, and exercise continuation intention. The subject of this study is the police officers belonging to the Busan and Gyeongnam Provincial Police Agency as of March 2021. Among them, a survey was conducted targeting 337 people who had experience participating in home training. As a result of the study, first, it was found that the expectations of home training were significantly correlated with exercise immersion and exercise continuation intention factors. Second, it was found that the expectation of home training participants had a significant effect on exercise immersion and exercise continuation intention. Third, exercise immersion of home training participants was found to have a significant effect on exercise continuation intention. Home training will be usefully used to prepare physical conditions for various public safety situations. If you training with a long-term plan rather than short-term training, you will be able to achieve the effect that home training seeks.

With strength training comes the risk of injury and the benefits of exercise. Lack of knowledge and experience or repetitions at excessive intensity can lead to injury. Adequate feedback on an exercise's progress can increase the exercise's effectiveness and reduce injuries by providing scientific data and psychological motivation. This study aimed to validate EMG equipment and examine the effects of 8 weeks of biofeedback training with wireless electromyography. A correlation analysis between the Noraxon device and Fitsig^®(EMG Prototype), a well-known instrument in the field of research, showed a moderate correlation. Statistically significant differences in humeral circumference, humeral muscle mass, and biceps and triceps strength were found between the left and right sides of the body over time, with no differences in the type of exercise. Feedback training with real-time EMG was found to be favorable for hypertrophic growth and strength improvement. Future studies should be conducted to investigate its application in sports activities further.
