Background: Backward walking exercise may offer some unique and potentially beneficial differences compared with forward walking exercise. There is still a lack of research on backward walking exercises and forward head posture. Objects: The purpose of this study was to determine the effect of backward walking exercise on college students forward head posture in their 20s. Methods: Twenty-one subjects participated in the experiment. The subjects were those with a craniovertebral angle (CVA) of 55 degrees or less who understood the purpose and method of this study and voluntarily agreed. A camera capable of taking pictures of the lateral plane was installed at a distance of 1.5 meters before exercising. Pictures were taken before walking backward, and after walking for 15 minutes on the treadmill, the images were taken in the same way. The composition of the backward walking exercise was walking at a rate of 1.0 for 5 minutes, and the remaining 10 minutes were walking at a rate of 1.5. Wilcoxon signed rank test was used to compare CVA and craniorotational angle (CRA) before and after exercise. Results: As a result of this study, there was a significant difference in CVA before and after exercise (p < 0.05). There was a significant difference in CRA before and after exercise (p < 0.05). Conclusion: The backward walking exercise and verbal command seems to have positively influenced the changes in CVA and CRA among college students in their 20s. It seems that studies to confirm balance or muscle activity as well as changes in forward head posture through the long-term intervention of the backward walking exercise should be conducted.

본 연구의 목적은 새롭게 개발된 Nurida-ball 공차기 운동기구의 효율성을 검증하기 위해 중년 남성을 대상으로 일회성 운동에 의한 운동 강도 측정과 장기간 운동에 의한 건강 관련 지표들을 확인하는데 있다. 첫 번째 연구에서는 Nurida-ball의 운동 강도를 측정하기 위해 8명의 중년 남성을 대상으로 30분간 Nurida-ball 운동을 실시하고 이를 트레드밀 운동부하검사에서(graded treadmill exercise test: GXT) 측정된 최대치와 상대적으로 비교 분석하였다. 두 번째 연구에서는 12명의 중년 남성을 Nurida-ball 운동 그룹(NB, n=6)과 대조군 그룹(CON, n=6)으로 구분하고 NB 그룹은 8주간 운동을 실시하였다(30min/day, 3 days/week). 이후 운동의 효율성을 검증하기 위해 신체구성, 심폐기능, 혈액 지질 성분 및 근 손상 지표를 확인하였다. 먼저 일회성 Nurida-ball 운동 시 나타난 운동 강도는 GXT-HRpeak(55~85%)과 $GXT-VO_2peak$(23~61%)으로 각각 나타났다. 8주간 장기간 운동을 실시한 연구에서는 CON 그룹과 비교하여 NB 그룹에서 체중, 체지방, 체지방율, 체질량지수의 변화량이(사후-사전) 통계적으로 유의하게 감소한 것으로 나타났다. 또한 NB 집단에서 운동 전과 비교하여 운동 후에 TC와 LDL는 감소되고 BMC는 증가하는 것으로 나타났다. GXT의 최대 환기당량과 수행시간의 변화량이(사후-사전) CON 그룹과 비교하여 NB 그룹에서 유의하게 증가한 것으로 나타났다. 특히 GXT의 운동수행시간은 NB 집단에서만 운동 전과 비교하여 운동 후에 유의하게 증가된 것으로 나타났다. 이를 종합해 보면 Nurida-ball 운동기구는 신체구성과 심폐기능에 긍정적인 영향을 미칠 수 있는 운동 기구로써 중년 남성들에게 나타나는 대사성 질환들을 완화시킬 수 있을 것으로 생각된다.

Purpose: Previous studies have suggested that BDNF has a role in plasticity and survival following spinal cord injury and treadmill exercise increases BDNF levels in the normal brain and spinal cord. We attempted to determine whether swimming exercise improve motor function following experimental contusive spinal cord injury and whether motor outcome is associated with BDNF expression. Methods: Thirty six Sprague-Dawley rats (weight, 250 to 300 g) were divided into control (n=18) and experimental swimming group (n=18). Spinal cord injury was produced using NYU-spinal impactor at the eleven thoracic levels in both groups. Swimming exercise started $7^{th}$ day from SCI operation, lasted 5 min per day, 5 days a week for 4 weeks and then exercise times a day were increased in one number to each week. Motor functional recovery was determined by the Basso-Beattie-Bresnahan (BBB) locomotor rating scale, modified inclined board plane test, histological findings, H&E and BDNF expression observed at $1^{th}$, $3^{rd}$, $7^{th}$, $14^{th}$, $21^{st}$ and $28^{th}$day after injury. Results: 1. The BBB scores were higher in experimental group than control group at $14^{th}$, $21^{st}$ day (left hind limb) and at $21^{th}$ day (right hind limb) (p<0.05) after injury. 2. The inclined board plane test were significantly greater in experimental group than control group at $7^{th}$ day (p<0.05), $14^{th}$ and $28^{th}$ day (p<0.01) after injury. 3. The BDNF expression was severe revealed in experimental group than control group at $7^{th}$, $14^{th}$ and $28^{th}$ day after injury. Conclusion: This study suggests that swimming applied from the early phase after spinal cord injury be beneficial effects in motor functional recovery.

Purpose: Menstruation is associated with menstrual symptoms like pain and balance problems which have an impact on the quality of life. Pilates increases pelvic stability and reduces menstrual pain by inducing abdominal muscle contraction. This study was done to evaluate the effects of Pilates on menstrual pain, symptoms, balance, and quality of life when compared to aerobic exercise. Methods: Thirty-nine women with menstrual pain were randomly divided into the Pilates group (n=13), aerobics group (n=13), and control group (n=13). The Pilates group performed lumbar-pelvic stabilization exercises, while the aerobic group ran on a treadmill. The control group did not undergo any intervention. The experimental groups exercised for four weeks (12 sessions) and did not exercise during menstruation. The Y-balance test was performed on the second day of menstruation to evaluate dynamic balance. The questionnaires administered immediately after menstruation were the visual analog scale (VAS), Korea Oswestry Disability Index (ODI), and the modified Menstrual Distress Questionnaire (MDQ). The paired t-test was used to compare the effect of exercise within the three groups and a oneway analysis of variance was used to compare between groups. Results: VAS and MEDI-Q scores significantly decreased in the Pilates group after 4 weeks compared with those in the aerobic and control groups. Moreover, ODI and Y-balance scores increased in the Pilates group compared with those in the aerobic and control groups (p<0.05). Conclusion: The Pilates stabilization exercises are effective and help in improving menstrual pain, balance and other menstrual symptoms assessed through ODI, and MEDI-Q, compared to aerobic exercises.

There are many types of walking exercise. We have choice the way according to the walking exercise purpose. Nordic walking(NW) is one of walking types with nordic poles. Also, power walking(PW) has motion of large swing the arm in walking, and dumbbell walking(DW) way is walking with 3-pound dumbbell. This study compared the physiological response(heart rate, energy expenditure) of general walking(GW) to another types(nordic, power, and 3-pound hand weights walking way). Seven apparently male health volunteers between the ages 19 and 24 years participated. Each complete a treadmill test. The tests were assigned randomly, as submaximal walking trials on separate days. Each walking trial was conducted on a level treadmill, for 40 minutes(3-5mile/hour 5min warm-up, 6mile/hour speed for 15min walking and 7mile/hour speed for 15min Jogging exercise, and 5-3mile/hour cool down 5min), at an same pace. Heart rate in beats per minute(bpm), and energy expenditure in kcal per minute(kcal/min) were recorded each minute. Results between trials were compared using repeated measures analysis of variance and Tukey's post hoc tests. In slow walking, it was found that walking with 3-pound hand weight way resulted in and average of ($127.8{\pm}8.27bpm$) the highest score HR, Caloric expenditure($85.4{\pm}14.51kcal/min$), responses compared to regular walking way($117.4{\pm}7.27bpm$ and $70.4{\pm}10.99kcal/min$). Nordic walking way($121.4{\pm}11.74bpm$, and $77.0{\pm}16.83kcal/min$) is second, power walking way($118.5{\pm}9.98bpm$, and $68.7{\pm}20.62kcal/min$) is next. In fast walking, it was found that walking way with 3-pound hand weight resulted in and average of ($160.1{\pm}8.72bpm$) the highest score HR, caloric expenditure($126.1{\pm}13.86kcal/min$), responses compared to regular walking way($148.4{\pm}11.94bpm$, and $109.0{\pm}4.70kcal/min$). Nordic walking way($156.7{\pm}10.82bpm$, and $113.5{\pm}14.51kcal/min$) is second, power walking way($149.7{\pm}12.56bpm$, and $109.2{\pm}17.64kcal/min$) is next. Thus, it is the unavoidable conclusion that, comparing with general walking, 3-pound hand weight walking, nordic walking, and power walking methods have the advantage of high exercise intensity and energy expenditure to meet the purpose of performers without the problem. Furthermore, 3-pound hand weight walking ways were proved to be a useful aerobic exercise method as whole body that achieves high-energy efficiency. To this extent, 3-pound hand weight walking ways can be recommended as a continuous and regulative aerobic exercise for some people.

The purpose of this study was to determine the effects of beverage temperature and composition on weight retention and fluid balance upon voluntary drinking following exercise induced-dehydration. Eight men who were not acclimated to heat participated in four randomly ordered testing sessions. In each session, the subjects ran on a treadmill in a chamber maintained at $37^{\circ}C$ without being supplied fluids until 2% body weight reduction was reached. After termination of exercise, they recovered for 90 min under ambient air conditions and received one of the following four test beverages: $10^{\circ}C$ water (10W), $10^{\circ}C$ sports drink (10S), $26^{\circ}C$ water (26W), and $26^{\circ}C$ sports drink (26S). They consumed the beverages ad libitum. The volume of beverage consumed and body weight were measured at 30, 60, and 90 min post-recovery. Blood samples were taken before and immediately after exercise as well as at the end of recovery in order to measure plasma parameters and electrolyte concentrations. We found that mean body weight decreased by 1.8-2.0% following exercise. No differences in mean arterial pressure, plasma volume, plasma osmolality, and blood electrolytes were observed among the conditions. Total beverage volumes consumed were $1,164{\pm}388$, $1,505{\pm}614$, $948{\pm}297$, and $1,239{\pm}401$ ml for 10W, 10S, 26W, and 26S respectively ($P$ > 0.05). Weight retention at the end of recovery from dehydration was highest in 10S ($1.3{\pm}0.7kg$) compared to 10W ($0.4{\pm}0.5kg$), 26W ($0.4{\pm}0.4kg$), and ($0.6{\pm}0.4kg$) ($P$ < 0.005). Based on these results, carbohydrate/electrolyte-containing beverages at cool temperature were the most favorable for consumption and weight retention compared to plain water and moderate temperature beverages.

PURPOSE: The purpose of this study was to investigate whether a circuit aerobic exercise program positively affects pulmonary function and gait endurance in chronic stroke patients. METHODS: Twenty-four chronic stroke patients were allocated equally and randomly to an experimental group (n=12) or a control group (n=12). All participants received 60 minutes of comprehensive rehabilitation treatment, the experimental group additionally performed a circuit aerobic exercise for 30 minutes, while the control group additionally performed a general aerobic exercise, i.e., gait training on the treadmill for 30 minutes. These 30-minute exercise sessions were held three times per week for six weeks. Pulmonary function was assessed using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and maximal voluntary ventilation (MVV), and gait endurance was assessed using the 6-minute walk test (6MWT). RESULTS: In the both groups, FVC, FEV1, MVV, and 6MWT were significantly increased after training. Members of the experimental group showed significant improvements in FVC, FEV1, and MVV, and significantly greater improvements than controls (p<.05). However, 6MWT improvements were not significantly different in the two groups (p>.05). CONCLUSION: The devised circuit aerobic exercise program offers an effective rehabilitation aerobic exercise for improving pulmonary function and gait endurance in patients after chronic stroke.
