Objective: The purpose of this study was to investigate the effects of an additional weight aquatic exercise program on the balance and lower extremity strength on aquatic environment in persons with stroke. Design: Randomized controlled trial. Methods: All subjects were randomly divided into three groups where thirteen subjects were in the additional weight aquatic exercise group, twelve subjects in the aquatic exercise group, and fifteen subjects in the control group. Subjects received a graded aquatic exercise program for 30 minutes, with 3 sessions per week for 6 weeks, and subjects in all groups received conventional physical therapy. All subjects were assessed with the Medical Research Council (MRC), the Berg Balance scale (BBS), Timed Up and Go test (TUG), and 10-meter walk test (10MWT) pre and post intervention. Results: The MRC, BBS, TUG, and 10MWT scores significantly improved post-intervention (p<0.05), and the control group also had significantly improved in all areas post-treatment (p<0.05). In addition, it has been confirmed that the additional weight aquatic exercise group had significantly improved in MRC, BBS, and TUG scores compared with the aquatic exercise and control group (p<0.05). Conclusions: The findings of this study suggested that the additional weight aquatic exercise program improves lower extremity and balance in persons with stroke.

Many researches of aqua exercise, one of effective management for arthritis patients to reduce pain and distortion of joint have been done. Actually in America water exercise programs have been actively practiced for arthritis patients. However the study and practice of water exercise can not be found easily in Korea. Considering that the effectiveness of aqua exercise has been evidently confirmed, the exercise should be fully utilized. Under this circumstance, we provide basic data for aqua exercise program through the research on the needs of water exercise and characteristics of arthritis patients. Summerising the result of this study, the primary needs of aqua exercise is to get additional effect of medical treatment for the patients, especially unsatisfied patients to the medical treatment. The level of needs shows very high as of 57.3% of total sample. The strength of needs has relation to economic status and sociality. Hospitals and health centers should develop aqua exercise program not as a simple physical exercise but as a medical management for arthritis patients. Institutional base must be prepared for the patients, who have weak economic, physical and social ability, to easily access to the benificial exercise.

Objective: The aim of this study is to test the effects of elastic band exercise accompanied by Swiss ball exercise on lower limb muscle strength, balance and pain in middle-aged women with osteoarthritis. Design: A randomized controlled trial. Methods: Thirty-five participants were randomly assigned to the experimental group (n=18), which performed elastic band exercise combined with Swiss ball exercise, and the control group (n=17), which performed elastic band exercise only. Both groups did a 30-minute session of exercise three times a week for eight weeks and were assessed for lower extremity muscle strength, static and dynamic balance, and pain levels before the first therapy session. All participating patients underwent outcome assessment after eight weeks of therapy without any additional treatment. Results: The experimental group made a significant increase in muscle strength of the lower extremities, static and dynamic balance ability, and pain level (p<0.05). The control group made a significant improvement in lower limb muscle strength, dynamic balance ability and pain level (p<0.05) with no such improvement in static balance ability. The exercise group made a significant increase in static and dynamic balance ability and pain level compared to the control group (p<0.05). Conclusions: These results demonstrated that both Swiss ball exercise and elastic band exercise were effective for middle-aged women with osteoarthritis and found that elastic band exercise combined with Swiss ball exercise produced more significant effects on their balance and pain.

Objective: The purpose of this study was to examine the effects of ankle Kinesio taping on range of motion and agility during exercise in university students. Design: Cross-sectional study. Methods: Thirty subjects were randomly allocated to two groups: taping group (n=15) and non-taping group (n=15). All groups underwent the same exercise program including stretching for 30 minutes. The exercise program proceeded in the following order: five minutes of stretching, a 20-minutes exercise program, and additional five minutes of stretching. Of the eight exercise methods suggested by Purcell et al, seven were chosen (lateral shuffle, forward and backward running, agility ladder, figure-of-8, forward jogging while jumping over cones, wall jumps and zigzags); $90^{\circ}$ cuts with lateral shuffle were omitted. The range of motion of ankle dorsiflexion and plantarflexion was measured using the goniometer. Agility was measured using the side hop test. Results: For ankle range of motion, the taping group showed significant differences in dorsiflexion and plantarflexion on both sides (p<0.05). The non-taping group showed significant differences only in left plantarflexion (p<0.05). There was a significant difference in dorsiflexion on both sides between the taping group and the non-taping group (p<0.05). All groups showed significant differences in agility on the left and right ankle (p<0.05). There was a significant difference in left ankles between the taping group and the non-taping group (p<0.05). Conclusions: Kinesio taping increased range of motion and agility during exercise in university students. Additional research on Kinesio taping for improving range of motion and agility is needed.

이상의 연구를 종합해보면, 장시간 운동시 BCAA 투여는 BCAA 산화시 발생되는 암모니아 등의 피로물질 축적에 의해 운동수행에 부정적 영향을 미칠 수도 있으나, 체내 글루코스가 소진되어가는 시점에서 유용한 에너지원으로 기여 되어 운동수행에 도움이 될 수 있다고 보여진다. 또한 OKG나 알부민을 가중투여하면 크렙스 사이클의 중간물질로 또는 유리지방산 동원의 운반자로서 BCAA 단독 투여시 부정적으로 나타난 원인을 해결하여 운동수행에 긍정적 영향을 기대할 수 있을 것으로 사료된다. 그러나 운동과 BCAA, 그리고 내분비 체계와의 관계는 각 호르몬의 역할과 기능에 따라 도출되는 결론이 다를 수 있어, 앞으로 BCAA 대사와 관련된 효소반응 등에 대한 추가적인 연구가 필요하다고 본다.

In this study, in terms of the exercise vehicles of the weapon systems having negative buoyancy, the analysis on the operation concepts was performed and the new methods of floating to surface were proposed. In case of having negative buoyancy, the additional methods for recovering the exercise vehicle have to be considered. As parts of recovering the exercise vehicle, for floating to surface the new methods of weight discharge, weight separation and sea water discharge were proposed. The conceptual design about sea water discharge method was performed. It was confirmed that those methods could be applied to the design of the exercise vehicle having negative buoyancy.

Purpose: This study aimed to explore the effects of additional trunk exercises on an unstable surface on the balance and walking ability of individuals with chronic stroke. Methods: Sixteen patients with chronic stroke participated in this study. The participants were randomly assigned to two groups: experimental group (n=8) and control group (n=8). All the participants underwent a typical physical therapy program for 30 min a day. Moreover, the experimental group participated in a 30 min trunk exercise program on an unstable surface, whereas the control group participated in a 30 min trunk exercise program on a stable surface. Both groups performed the exercises five times a week for three weeks. The Berg Balance Scale (BBS) was used to measure changes in balance. The gait variables were measured using the GAITRite system (CIR System Inc., Clifton, NJ, USA) to examine changes in walking ability. Results: Both groups showed a significant intragroup improvement in balance, gait speed, cadence, stride length, and double support period (p<0.05). In the intergroup comparisons after the intervention, the experimental group showed significant improvements over the control group in balance, gait speed, cadence, stride length, and double support period (p<0.05). Conclusion: This study applied additional trunk exercises on an unstable surface to chronic stroke patients, and the results showed a significant improvement in the patients' balance and walking abilities. Therefore, trunk exercise on an unstable surface may be applicable as an intervention method to improve the balance and walking ability of chronic stroke patients.

Sports drinks help optimize and improve performance by delaying and eliminating the buildup of fatigue-causing substances in the body during exercise. Saengmaeg-san is a nature-friendly traditional beverage that has no side effects on the human body and can quench thirst. However, studies on the relationship between exercise ability and Saengmaeg-san are insufficient. The purpose of this study was to prescribe Saengmaeg-san during the summer training period of 4 weeks and to analyze the effect on body composition and exercise performance. Seventeen male participants were divided into 3 groups (Saengmaeg-san acid intake group [n=9], placebo group [n=8]), and body composition (height, weight, muscle mass, fat mass, BMI) and conducted exercise performance (total exercise time and HRmax). In our study, Saengmaeg-san intake had a positive effect on exercise performance, such as decreased body fat percentage, increased exercise time, and decreased HRmax. Therefore, Saengmaeg-san showed the potential as a sports drink. In the future, additional studies on fatigue-related substances, immune function-markers, and blood lipids are needed in order to clearly explain the change in exercise performance due to consumption of Saengmaeg-san.

Objective: Exercise is a risk factor for infertility in women. However, research on the effects of different intensities of exercise on folliculogenesis has not yielded clear results. This study was conducted to analyze the effects of differences in the intensity of exercise on folliculogenesis in mice. Methods: Nineteen female BALB/c mice (age, 3-4 months; weight, 13-25 g) were randomly divided into four groups: control, mild exercise, moderate exercise, and high-intensity exercise. The mice in the exercise groups engaged in swimming, with additional loads of 3%, 6%, or 9% of body weight, respectively. There were five swimming sessions per week for 4 weeks, with a gradually increasing duration every week. At the end of the treatment, ovarian extraction was carried out and hematoxylin and eosin staining was performed to identify folliculogenesis. Results: There were significant differences in the number of total follicles between the control and moderate-exercise groups (p=0.036) and between the mild- and moderate-exercise groups (p=0.005). The mean number of primary follicles was higher in the moderate-exercise group than in the mild-exercise group (p=0.006). The mean number of secondary, tertiary, and Graafian follicles did not differ significantly among groups (p≥0.05). However, the number of total follicles and follicles in each phase tended to increase after exercise, especially moderate-intensity exercise. Conclusion: Exercise of different intensities affected the total number of follicles and primary follicles. The number of follicles of each phase tended to increase after exercise. Moderate-intensity exercise had better effects than other intensities of exercise.
