The purpose of this study is to analyze the accessibility to the place for outdoor exercise. For that, the departure (resident) location of the users of outdoor exercise equipment within 12 parks in Seoul have been investigated. A total of 1,733 people have been surveyed during the two-week period between Aug.2 and Aug. 15 and 815 cases were analyzed. We also investigated demographic characteristics, access method and related factors such as location, climate and visiting time. The results were coded through ArcGis program and the accessibility to each exercise location, difference in regional accessibility and accessibility characteristics in terms of climate and time have been analyzed. The results are as follows: First, visitors to the Han River start from the places further than the visitors to the streamlines. Second, the average moving distance is longer for the users aged under-60 than for the users aged 60 and over to reach the exercise place. And the average moving distance for visitors to the Han River destination is the longest with 748 meters, followed by 203 meters for general parks and 92 meters for streamline parks, respectively. Third, in each non-waterfront parks, the moving distance by users under-60 was longer by about 230 meters than that by users 60 and over. Fourth, exercisers in the weekend travel more by 244 meters than those during the midweek users to reach the exercise place. Fifth, the number of visitors to the Han River increased in the weekend while visitors to the streamlines decreased in the same period. Sixth, the traveling length for bicycle users is three times as much as that for pedestrian visitors. And the departure locations of bicycle users were more widely distributed.

This study has observed 12 parks (20 spots) in Seoul to know the number of users, gender, age groups for the units of 30 minutes from 06:00AM till 10:00PM. According to the systematic characteristic of the surveyed outdoor exercise place, the details of their users during the summer time were analyzed from the objective viewpoint. Major results of analysis are as follows: Firstly, in case of the riverside of the Han River 07:00AM marked a mini peak and 21:00PM reached the peak, and in case of sub-stream neighborhoods, 21:00PM showed only one peak. On the other hand, in case of neighborhood parks (including pocket park) no peak time was noticeable. Secondly, in case of the riverside of the Han River and the neighborhoods of sub-streams, people used the exercise equipment remarkably at night, and in case of neighborhood parks people used the exercise equipment a little bit more in the morning than in the afternoon. Thirdly, in case of nights in summer the riverside of the Han River was preferred by men, while the neighborhoods of sub-streams were preferred by women and the neighborhood parks showed no difference in the number of users among men and women. Fourthly, differently from men, women do not regard the exercise so seriously as men and their purpose of using outdoor exercise place is to use their leisure time mostly with their family members or neighbors, and women prefer light and comfortable exercises. Fifthly, in summer even those who like to exercise a lot like to exercise in the morning to avoid summer heat. Therefore, provision of shades in summer is very important.

This study is to present objective data for the approaches of therapeutic exercise for the correction of genu varum by making an analysis and a comparison of the hip joints' ROM and isokinetic muscles of the female college students with straight legs with those of a female college student with idiopathic genu varum. Additionally, the state of the adductor muscle's thighs and the deep muscles of the subjects with bowed legs were experimented and the equipment's effect and applicability was reviewed through the process of the movement of newly developed exercise equipment, Balloa(2013, Balloa/Adonia/Korea). As a result, a person with genu varum needs the height increasing method for increasing external rotation ROM of a hip joint and requires the exercise techniques to strengthen external rotator muscles and to inhibit the activity of internal rotator muscles of a hip joint. Balloa increases the external rotation ROM of a hip joint and strengthens gluteal muscles, deep muscles, and adductor muscles, and the equipment's function of muscle strengthening shows that the equipment is an effective corrective exercise for the patients of genu varum.

Purpose: This study was conducted to verify the effect of applying a pressure biofeedback unit on walking ability and knee joint function while performing knee joint extensor strengthening exercises using resistance exercise equipment in total knee replacement (TKR) patients. Methods: This study was conducted on twelve patients receiving rehabilitation treatment after being admitted to a rehabilitation hospital post-TKR. Of these, six were allocated to a feedback group with a pressure biofeedback unit, and the other 6 were allocated to a control group without a pressure biofeedback unit. The subjects performed an exercise program for 45 minutes per session, five times a week, for two weeks. Walking ability and knee joint function were evaluated and analyzed before and after exercise. Results: The feedback group showed significantly better improvements in walking speed, gait cycle, step length on the non-operation side, time on the foot on the operation side, K-WOMAC stiffness, and K-WOMAC function than the control group (p<0.05). Conclusion: When strengthening the knee joint extensor muscles using resistance exercise equipment in TKR patients, the provision of a pressure biofeedback unit was found to improve walking ability and knee joint function by inducing concentric-eccentric contraction of the knee joint extensor muscles. Therefore, the study shows that exercise based on the provision of a pressure biofeedback unit should be considered when strengthening knee joint extensor muscles to improve the walking ability and knee joint function of TKR patients in clinical practice.

The purpose of this paper is to study and propose playground facilities for physically challenged children to cultivate adaptability in society and advances the opportunity of participate in physical exercise. This study carried out site investigations by visiting and inspecting various facilities: a recreational walking path for physically challenged people, a care facility for physically challenged children, a special school for physically challenged children, and "Madel Park", a private-use playground for physically challenged children. The result of the site investigation found that, overall, play facilities are difficult to use for physically challenged children. In addition, because park space is often small and narrow, children who are restricted to wheelchairs find it impossible to access such facilities. By carefully inspecting each of the facilities, the author found suitable elements to apply for outside play space. These elements include the introduction of an essential slope way to allow for safe movement, the provision of special seats which support the body to outside play equipment and the adaptation of treatment room instruments that assist balance to outdoor playground facilities. On the basis of the site investigation the interview and the indoor education program for physically challenged children the author completed an outside play program. Each item in this program was classified as belonging to either a "sense play" program or and "exercise play" program. Finally, the author designed suitable play equipment for physically challenged children corresponding to each item in the exercise programs in order to research the appropriateness of the equipment to its intended use. This research is the first step. From this point the author expects that specific applications will be developed through a practical space plan and sufficient clinical experiments involving use of the new equipment.

Objective: This study aimed, first, to develop core strength training equipment with elderly-friendly, easy-to-use features and, second, to investigate the effect of core strength training using the equipment on the performance and stability of the elderly in activities of daily living. Method: In this study, we developed training equipment with a stability ball that can be used for performing core strength exercises in the elderly. Twenty-three elderly subjects (age: $77.87{\pm}6.95years$, height: $149.78{\pm}6.95cm$, and weight: $60.57{\pm}7.21kg$) participated in this study. The subjects performed the core strength training exercise with 16 repetitions for 8 weeks (2 repetitions per week). Performance in activities of daily living was assessed by using the Short Physical Performance Battery (SPPB), a test of going up and down 4 stairs, and one-leg static balance test. Stability was quantified as changes in the center of pressure (COP) and C90 area. Results: With the core strength equipment, trunk core strength exercise could be performed by pulling or pushing a rope with 2 hands on the stability ball. During the task, the tension in the rope was manipulated by a motor connected to the rope and the COP of the subject was measured by 4 load cells mounted in the equipment. Our results showed that the SPPB score was significantly higher (p < .05), the time to complete the "going up and down 4 stairs" test was significantly shorter (p < .05), and one-leg static balance statistically improved under an eyes-open condition (p < .05) after as compared with before the core strength training. The changes in the COP in the anteroposterior and mediolateral directions, and C90 area were significantly lower in the posttest (p <. 05) than in the pretest. Conclusion: The core strength training exercise using the equipment developed in the present study improved the performance and stability of the elderly in activities of daily living.

The purpose of this study is to increase the usage of satisfaction of outdoor exercise equipment installed at parks when plans and designs are made for renovation or formation of parks. In order to do so, the study surveyed and analyzed the usage satisfaction of 150 men and women who use outdoor exercise equipment in neighborhood parks located in Dongtan New Town. There were four factors that affect the variables of usage satisfaction. They can be defined as the main facility factor, awning factor, maintenance factor, and additional facility factor. From the result regression analysis of the total satisfaction rate and the factors, the main facility factor was the most influential of the variables. This could indicate that the facility factor affects the satisfactory rate of outdoor exercise equipment. This research is done only with the examples of neighborhood parks, so it limits the possibility of analysis of seasonal use. It is necessary to conduct analysis research of parks which installed many outdoor exercise equipment, such as a vest-pocket park, children's garden, and pedestrian/urban/metropolitan neighborhood parks.

The purpose of this study was to verify the validation of exercise effect with loading deviation during rowing exercise. We performed evaluation of based physical fitness and joint torque before the experiment for finding muscle unbalance. So we recruited twenty four subjects who have bigger muscle strength in more 20% than average one. Subjects divided two groups. One is dominant upper limbs(DU) and the other was dominant lower limbs(DL). Subjects performed rowing exercise using electric equipment (Robo.gym.Humonic.korea). Exercise is performed four sets a day including 25 times a set, and three days a week. Measurement consist of evaluation of based physical fitness and joint torque using biodex(biodex system3.USA). Evaluation of exercise effect performed each week in joint torque of shoulder, lumbar and knee joint and each month in based physical fitness. Also we adapted 30% of 1RM for muscular endurance and 70% of 1RM for muscle strength as exercise load. The results showed that the difference of maximal peak torque were getting increase significantly during exercise. Also difference of various factor in based physical fitness were getting increase significantly except flexibility and agility. This interpreted that rowing exercise with loading deviation types could provide muscle strength and muscular endurance exercise in same time. These results could be interpret to two ways. One is effect of improving physical fitness for rowing exercise and the other meaned validation of loading deviation in rowing exercise. Our study is going to verify the validation of loading deviation during rowing and we found out that loading deviation could provide muscle strength and muscular endurance exercise for improving muscle unbalance. Our study can be used development of exercise equipment and program for normal people with muscle unbalance. Also that provide effect of whole body exercise to anybody.
