류마티스 환자들이 수중운동을 하면 통증이 감소되는 등 긍정적인 효과가 발생되지만, 통증이 감소되는 원인은 확실치 않고 이에 대한 연구는 미비한 실정이다. 따라서 수중운동 시, 발 표면에 흐르는 유동을 분석해 통증이 감소되는 원리를 규명하고자 한다. 본 연구에서는 유동의 흐름을 분석하기 위해 Unsteady 해석을 진행하였으며, 다리를 들어 올리는 동작과 내리는 동작을 총 3회 반복설정하여 해석을 수행하였다. 또한 통증이 있는 부위에 압력점을 지정하여 압력변동 및 주파수를 분석했다. 그 결과 전반적으로 양압과 음압이 약 ±500Pa의 압력이 가해지고, 운동 방향을 전환할 때에는 약 ±2000Pa의 압력이 가해지는 것을 확인했다. 또한 류마티스 통증이 빈번하게 발생하는 부위에 약 35 ~ 80Hz 정도의 주파수가 발생하였다. 지속적인 압력변동과 주파수가 통증부위에 반복적으로 가해지면 혈액순환이 증진되고, 통증이 감소되는 효과를 예측할 수 있다. 본 연구의 결과는 수중운동의 효과 및 원리를 이해하는 자료로 활용이 가능할 것으로 사료되며, 수중운동의 프로그램 개발을 보조하고, 관련 의료 보조기 개발을 위한 기초 자료로 활용될 수 있을 것이다.

The aim of this study was to evaluate the effect of hot water extract of peduncle obtained from Hovenia dulcis Thunb (HD) which is commercially developed for the protective effect on the alcoholic hepatotoxicity, on the endurance capacity for weight loaded forced swimming mice. The swimming times to exhaustion in mice fed 100 and 200 mg/kg HD for 2 weeks were prolonged 3.6 and 3.7 fold, and for 4 weeks 1.9 and 2.7 fold compared with each vehicle control ($42.8{\pm}20.5$ min and $67.7{\pm}47.8$ min, for 2 and 4 weeks), respectively. Blood biochemical parameters for ALT, AST, creatinine and BUN were not significantly different between from HD fed or control mice. Although HD fed mice swam over 2 fold longer time than vehicle control mice at 4 weeks, blood biomarkers of physical fatigue such as glucose, triglyceride and free fatty acid, lactate were not significant different and even tended to ameliorate. Hepatic lipid peroxidation and SOD activity did not significantly change in HD fed- and vehicle control exhausted swimming mice at 2 or 4 weeks. However, catalase activity in HD-fed mice was significantly increased in a dose-dependent manner compared with vehicle control mice. The present study indicates that HD improved physical fatigue and exercise performance in mice. Therefore, it has a potential for the pharmacological effect of anti-fatigue.

The purpose of the present study was to explore the most effective body region and cooling temperature to alleviate heat strain of workers in hot environments. We developed liquid cooling hood, vest, sleeves and socks and applied the water temperatures of 10, 15, 20, and 25℃ through the liquid cooling garments in a hot and humid environment (33℃ air temperature and 70% RH air humidity). A healthy young male participated in a total of 16 experimental trials (four cooling garments × four cooling temperatures) with the following protocol: 10-min rest, 40-min exercise on a treadmill and 10-min recovery. The results showed that rectal temperature, mean skin temperature, and ratings of perceived exertion during exercise; heart rate and diastolic blood pressure during recovery; and total sweat rate were lower for the vest condition than other garment conditions(p < .05). However, there was no differences in mean skin temperature among the four cooling garments when we compared the values converted by covering area(%BSA). When we classified the results by cooling temperature, there were no consistent differences in thermoregulatory and cardiovascular responses among the four temperatures, but 25℃ water temperature was evaluated as being the most ineffective cooling temperature in terms of subjective responses. In conclusion, the results indicated that wearing cooling vest with < 20℃ cooling temperature can alleviate heat strain of workers in hot and humid environments. If the peripheral body regions are cooled with liquid cooling garments, larger cooling area with lower cooling temperature than 10℃ would be effective to reduce heat strain of workers. Further studies with a vaild number of subjects are required.
