This study examined the indoor exercise environment use and needs of older adults. The target population was seniors aged 60 years and older living in a newly developed apartment complex. Variables include demographic and housing characteristics, status of exercise, and indoor exercise environmental evaluation and needs. A total of 102 data items were analyzed using frequency, t-test and ANOVA. Noteworthy results are as below. First, community centers and community welfare centers were the most desirable exercise environments because of affordability, exercise programs/spaces. Such exercise environments should be developed in more locations for increasing numbers of seniors. Second, indoor exercise environments need to be improved based on seniors' physical capabilities and environmental behavior. Third, supportive spaces such as restrooms, shower rooms, locker rooms should be carefully designed. Fourth, seniors wanted to have walking trails and indoor swimming pools, the most desirable exercise spaces, within ten to 15 minutes walking distance.

Purpose: This study examined the effects of horse riding simulator exercise on the thickness changes in the transverse abdominis in normal adults. Methods: Forty-five healthy adults were recruited and randomized to a horseback riding simulation exercise group (n=15), a sling exercise group (n=15), and a trunk stabilization exercise group (n=15). A horseback riding simulator offers the indoor experience of horseback riding and mimics the rhythmic movement of horseback riding, thereby provided a virtual environment, such as riding a real horse on the front screen. The velocity of the horse riding simulator exercise was regulated within the subject's ability to control the exercise on the horse riding simulator. A sling exercise group performed sling exercise under the inspection of the experimenter. In the trunk stabilization exercise group, the subjects were instructed to perform the exercise accurately and pause the session when pain occurred during the intervention. The subjects in each group carried out the interventions three times per week for six weeks. The thickness of the transverse abdominis was measured using a pressure biofeedback unit and the ultrasound. Results: Significant differences in the thickness of transverse abdominis within the groups were observed between before and after the interventions. On the other hand, there were no differences in the parameters among the groups. Conclusion: Horse riding simulator exercise can be an alternative to trunk stabilization exercise by increasing the thickness of the transverse abdominis in healthy adults.

This study compared the thermal comfort of indoor clothing from Tencel material that is getting higher in demand due to being eco-friendly with superior wettability, with that from Polyester material that despite being most widely used for indoor clothing, rapidly discharges body sweat due to low wettability. The experiments were performed in the two manners, objective evaluation under the conditions of an artificial climate chamber and subjective evaluation of wearing the given clothes at home followed by filling in the questionnaire. Subjects were 8 healthy elderly women in their 60's who spend majority of their time at home rather than in social activities, and comparison was made on skin temperature and humidity inside clothing at exercise and relaxation states under early summer environment. Based on these results, wearing Tencel material clothing maintained cooler temperatures under warm environment rather than when wearing Polyester material clothing, thus enabling activities under more comfortable state. Regarding humidity inside clothing, parts with twofold clothing did not show difference between Tencel and Polyester, but the onefold arm showed lower when wearing Tencel. With this results, Tencel is regarded as more comfortable and nicer than Polyester.

Objective: The aim of this study is to investigate the effect of biomechanical variables on gait according to indoor and outdoor environmental conditions in elderly women at risk of falling. Method: 26 elderly women aged 70 years or older, and consisted of 13 elderly people with a walking speed of less 1.0 m/s and 13 people in the fall risk group as normal groups. Depending on the purpose of the study, physical examination and psychological questionnaire were prepared, and then walking was performed in an indoor/outdoor environment, and the gait pattern, muscle activity, and plantar pressure results were compared and analyzed in the elderly females through a 2 group × 2 environment 2-way repeted ANOVA analysis. Results: The gait variable showed an interaction effect the cadence. The muscle variables showed interaction effects in the rectus femoris and tibialis anterior muscles, and the interaction effects of the plantar pressure variables were confirmed in the forefoot and midfoot of the contact area, and the midfoot of the mean pressure. Conclusion: These results indicate that both groups are exposed to falls risk when gait in an outdoor environment, but the fall risk group has a higher risk of falls in both the gait pattern, muscle activity, and plantar pressure variables. The results of this study are considered to be helpful as basic data and development of exercise programs to prevent falls.

The purpose of this study was to evaluate far-infrared clothing (FIR condition) with non-far-infrared clothing (Control condition) to assess the effects of FIR on thermo-physiological responses. Eight young healthy males (23.0±2.3 yr, 176.5±3.7 cm, and 69.0±4.3 kg) participated in this experimental trial, which consisted of a 20 min rest followed by a 40 min walk (4.0 km·hr^-1) and a 20 min recovery at 20℃ with 50%RH. The results showed that finger skin blood flow and mean skin temperature were significantly higher for the FIR condition than the control during exercise and recovery (p<.001). Clothing microclimate temperature of the FIR condition was 0.5℃ higher on the back (p=.001) and 0.4℃ higher on the thigh (p=.015) during recovery. Clothing microclimate relative humidity of the FIR condition was 13% higher on the chest (p=.006) and 19% higher on the back (p<.001) during exercise than control. Subjects felt warmer and more comfortable in the FIR condition than in the control (p<.05). Perceived skin wettedness (%BSA) was less in the FIR condition than in the control (p=.001). These results indicate that ceramic-embedded clothing had significant effects on thermoregulatory responses for light activity in an indoor environment.

The Qualitative improvements of outdoor spaces are unsatisfactory in comparison with that of indoor environment in existing apartments. Lately construction companies are differentiating the outdoor spaces of apartment complexes to meet needs of residents. However, high-rise buildings inherently have limitations on providing exposure to the outdoor settings and inappropriate lightings could have serious impacts on physical and psychological health of residents. Therefore, the purpose of this study is to provide useful information for the luminous environment of outdoor spaces through the analysis of current apartment complexes' lighting plans. Outdoor space of branded apartment complexes in Seoul, built after the year 2003, were researched. Through site visits, illumination level and lighting plans were investigated classified into entry area, passage area, plaza, rest area, exercise area, and play area. With the result, illumination level of apartment complexes researched was lower than KS illumination standard in all areas and the lighting plans were mostly shown in different condition of first intended lighting plan because of insufficiency of maintenance in lighting system. Therefore, it is need to provide better luminous environment to make outdoor space more lively and energetic at the night time.
