The objective of this study was to analyze the factors affecting the stages of change of exercise in middle-aged men who work. 170 middle-aged men who work surveyed, 40 to 59 years old, is residing, Chung-Buk and Chung-Nam province, who understand the purpose of this study and agree to participate in this study. This study data is analyzed by using frequency, percentage, standard deviation, t-test, 𝑥2 test and Logistic regression analysis. The study show that the exercise self-efficacy(𝛽=.965, p=.003) and the perceived health status(𝛽=.805, p=.025) among middle aged men who work have an effect on the stages of change of exercise meaningfully. That is, the exercise self-efficacy of middle aged men who work who have exercise behavior is 2.6 times higher than middle aged men at work who don't have exercise behavior, and the perceived health status is 2.2 times higher. This study suggests that the development of better exercise practice for middle aged men who work should be aimed at promoting exercise self-efficacy and perceived health status, Based on this, it is necessary to find ways to operate exercise programs at the workplace and community level.
This study analyzed the patent status of the outdoor exercise equipment used primarily by the elderly. The purpose is to utilize the basic data obtained to promote the health of the elderly. The information on the patent was collected from KIPRIS, an information search service provided by the Korean Intellectual Property Office. The search term used was 'outdoor exercise equipment', directly related patents were selected, and a final 157 were analyzed. As a result of the analysis, first, patent registration began in 2007, and 2-3 patents were registered on average every year. Second, patents from the perspective of sports convergence that provide an exercise prescription system using wireless communication, such as the ability to generate electricity by operating a power generation module, providing information on the user's exercise amount, or preventing the loss and theft of weights and safety accidents due to their characteristics, were searched for. Lastly, patents related to exercise equipment that can provide user convenience and increase the frequency of use of exercise equipment were searched. The results of this study confirmed that outdoor exercise equipment is being developed more for the elderly and their convenience, and that companies and public institutions are showing increased interest in outdoor exercise equipment for the elderly. In addition to patent trends analysis, follow-up research in connection with exercise programs using outdoor exercise equipment is needed to develop practical and convenient outdoor exercise equipment in the future.

The study aim was to investigate a comparison of muscle activity fatigue between maximal and submaximal strength gains during the bench press in men. It was hypothesized that maximal voluntary contraction (%MVC) would similar gains between maximal and submaximal strength gains during the bench press, but median frequency (MDF) would increase in maximal compared with submaximal exercise. Employing a randomized, counterbalanced crossover design, 12 men were asked to perform maximal repetitions and submaximal repetitions (concentric: 1-s, eccentric: 1-s, 2-s/repetition) to failure with a load of 85% of 1RM for the bench press, with a 3-minute recovery between the sets. Each subject was tested for the number of repetitions and sets, total work in bench press. Surface electromyography (EMG) was recorded from the pectoralis major, deltoid anterior, and triceps brachii for %MVC and MDF. Total work was significantly higher in the submaximal repetition exercise than that the maximal repetition exercise (p<.05). Muscle fatigue of pectoralis major, deltoid anterior and triceps brachii were significantly smaller in the submaximnal repetition exercise than that the maximal repetition exercise (p<.05, respectively). However, muscle activity of pectoralis major, deltoid anterior, and triceps brachii were not significantly different between exercises. Our study showed that a smaller muscle fatigue in submaximal repetitions, despite higher in total work and a similar in muscle activity were observed. These results suggest that submaximal repetitions during the bench press would be enhanced intensity and/or volume compared with maximal repetitions exercise.

The purpose of this study is to investigate and reveal the effects that the complex exercise training consisting of aerobic exercise and strength training(sit up, push up) that everyone can easily practice regardless of a time and a place in order to manage practically the physical strength of the aged affects the difference on their body composition and the change of physical fitness level. Looking into the change of body composition of an experimental group, the weight of 2.5kg was reduced after applying complex training for 12 weeks and the body fat mass of 2.65kg was reduced. Also, the abdominal fat of 0.13% was decreased and the muscle mass of 1.56kg was increased. For the change factors of physical fitness, cardiovascular endurance, muscular strength, muscular endurance, balance and flexibility excluding agility showed significant improvement after applying complex exercise training. The improvement of health fitness of the aged under this study was significantly effective to improve specified body functions which had been lowered by aging and insufficient physical activities. So, it is regarded that their health fitness is the important factor to improve the activity competence required for daily life and to lead healthy living by the improved activity competence. Henceforth, it needs to study more the complex composition of several sports, exercise intensity and the frequency based on the previous researches and studies. In addition, it needs to develop the complex exercise training in accordance with various characteristics such as a sex of the aged, an age, a physical fitness level, environment, a disease and the program in consideration of the efficacy and safety during training.
Objective : The purpose of this study was to investigate the effects of acupuncture treatment on frequently adopted acupuncture point and self exercise therapy for lumbar sprain patient Methods : For this study, a retrospective chart review was conducted. Data are derived from lumbar sprain patients who have received hospital treatment in Daejeon Univ. Cheon-Ahn Korean Hospital. All patients were treated with acupuncture treatment on high frequency acupuncture point (BL25, BL23, BL24, GB30, BL40, BL26, BL60, GB34), physical therapy and herbal medicine and self exercise therapy(Swiss ball exercise, Lumbar stabilization exercise.) We measured visual analogue scale(VAS), Oswestry disability index(ODI), Pain threshold twice(pre-treatment and post-treatment) on 1st day and 5 days later. Results : After being treated, lumbar sprain patients were meaningful improved in VAS, ODI, pain threshold The VAS score, ODI score were statistically decreased after treatment and the pain threshold was statistically increased after treatment. Conclusion : In this study, treatment on frequently adopted acupuncture point and self exercise therapy were effective on lumbar sprain patient.
A survey was conducted on 222 students in two elementary schools in rural areas, one was a rural small city and the other was in the countryside. By measuring their skin-foldness in 4 spots by caliper, the body fatness of 5 grades(BFGr) of the subjects was resulted as follows ; 28.0% of boys and 6.7% of girls were classified as obese the and 34.1% of boys and 31.1% of girls as overweight. Comparing by region, children in the small city seemed to be fatter than the ones in the countryside(21.7% vs. 17.2% as obesity). Comparing by gender, boys were fatter than girls(28.0% vs. 6.7% as obesity). When recategorizing body fatness from 5 grades(BFGr) into 3 groups(BFGp) as overweight group(obesity+overweight), normal and underweight group(underweight+severe-underweight), we observed no significant difference in childrens dietary habits and food intake frequencies by BFGp. Overweight and underweight groups enjoyed snacking before dinner more frequently than the normal group(42.1-59.3% vs. 31.5%). The subjects showed poor nutrition knowledge score with relatively high attitude score about weight control and dietary behavior score was a little lower than the attitude score. Nutrition education programs, like camps, should stress on childrens nutrition knowledge. BFGp related to obesity attitude positive, a very low level and the latter related to diet, exercise and fasting attitudes at positive levels. Therefore overweight children seemed to be motivated easily. Also the higher the in exercise-value score, the more increased was shown in exercise attitude at positive, very low level. Emphasizing exercise-value in camp programs might make childrens exercise attitude more positive. As strategies for a rural obesity camp program are being developed by obese and non-obese children. The camp would be held over summer vacation for 3 days(2 nights) at the participants expence not exceeding 50,000 won. Contents of the program cover nutrition knowledge, and exercise-value as well as cooking lessons, exercise practice, and self-esteem enhencement.
This study was designed to investigate the effects of aerobic and /or Ca supplementation for six months on lipid metabolism and blood pressure in postmenopausal women. The subjects were healthy 29 women aged from 60 to 70 years old. They were divided into four groups: placebo and Ca supplementation group with and without exercise. The amount of Ca supplemented was 500mg a day. The frequency of doing exercise was three times a week and each time, it took 40 minutes to complete all the course of aerobic dancing programmed for old women. During the experimental period, the subjects ate their usual diets and the use of druge as well as additional exercise was prohibited. The results were summarized as follows. 1. Percent body fat and BMI were significantly decreased and the body weight tended to decreased due to aerobic dancing. 2. Serum lipids content tended to show only a slihgt changes due to Ca supplementation: serum triglyceride, total-chol, LDL-chol, FFA content tended to decrease but serum HDL-chol / LDL-chol ratio tended to increase after the experiment in Ca group. On the contrary, serum lipids level was not changed by exercise. 3. Blood pressure did not show any significant changes by Ca supplementation and / or exercise for 6 months in old women. 4. Serum Ca level of Ca group was significantly increased after experiment in Ca group (p<0.05) but not in Ex-Ca group. In summarization, it appeared that the aerobic dancing was a definite way to reduce percent body fat and BMI in postmenopausal women. On the other hand, Ca supplementation seemed to be able to induce favorable changes in serum lipids. However, any synergistic metabolic effects of exercise and Ca supplementation was not seen in this study. Further study is needed to elucidate the relationship between exercise and/or Ca supplementation and the changes in blood lipids profile as well as blood pressure more clearly.
The stability of protein tissues and protein fibers in the human muscle is investigated in the presented paper. The protein fibers are modeled via tube structures embedded in others proteins fibers like the elastic substrate. Physical sport and physical exercise play an important role in the stability of synthesis and strength of the protein tissues. In physical exercise, the temperature of the body increases, and this temperature change impacts the stability of the protein tissues, which is the aim of the current study. The mathematical simulation of the protein tissues is done based on the mechanical sciences, and the protein fibers are modeled via wire structures according to the high-order theory beams. The thermal stress due to the conditions of the sport is applied to the nanoscale protein fibers, then the stability regarding the frequency analysis is investigated. Finally, the impact of temperature change, physical exercise, and small-scale parameters on the stability of the protein tissues are examined in detail.
This study investigates the stability of protein tissues regarding the vibration analysis based on the classical beam theory coupled with the nonlocal elasticity theory concerning the exercise impact. As reported in the previous research, four different types of protein tissues are supposed, and the influence of sports training is investigated. The protein tissues are made of protein fibers surrounded by an elastic foundation. The exercise enhances the muscle area and plays an essential role in the stability and strength of protein and muscle tissues. The results are examined in detail to examine the impact of different parameters on the stability of nano protein fibers.

This study was performed to measure the liquid intake and the liquid intake difference by obesity, exercise frequency, and salty food intake score in female high school students. A total of 235 students in Daejeon area were participated, and the liquid intake was recorded for 3-days(2 weekdays and 1 weekend) by self-recording. The T-test, F-test, Pearson's correlation, and Scheffe test were exercised. The results of this study are as follows. The amount of total liquid intake was 838.5 ㎖/d. Among the 13 kinds of beverages, water was the highest 611.6 ㎖/d, 72.9% of liquid intake total, followed by carbonated drink(65.7 ㎖/d), milk(41.6 ㎖/d), fruit drink(32.8 ㎖/d), and fruit·vegetable juice(25.4 ㎖/d). The other beverages' intake were very small, ≤13.0 ㎖/d. Carbonated drink, milk, and coffee's intake were higher during weekend than weekday. There were sig. difference in water and total liquid intake by the obesity, student of BMI≥23.0 was higher than students of BMI<23.0. And only carbonated drink was sig. different by exercise frequency and salty food intake score. Exercise frequency of ≥3 d/week and salty food intake score of ≥7(very dangerous) consumed more carbonated drink than the lower counterparts. Total liquid intake of female high school students was not reach to 900 ㎖/d, the Adequate Intake in Dietary Reference Intake for Koreans 2015. The amount of milk intake was 41.6 ㎖/d, far less than the Recommended Intake of 2 serving, 400 ㎖/d. Education and promotion program may necessary to increase the liquid intake amount and to choose the nutritious beverage.
