The survey was conducted to investigate athletes# beverage drinking pattern and their knowledge concerning hydration and fluid replacement. The subjects were 371 collegiate athletes (235 males and 136 females) in Seoul and Daejun area. The mean age of the athletes was 20.44 y. The prevalence of sports drink use among subjects at ordinary time, after training, and after competition were 9.0%, 17.1%, and 57.3% respectively. Primary source of sports drink information were advertisement (57.3%), friends or colleagues (14.9%), and coaches (7.0%) The purchase of sports drink was done by athletes themselves (76.0%) and coaches (22.6%). The most influential factor in choice of sports drink was taste (61.5%), brand name (15.1%), composition (12.4%), and advertisement (6.7%) However, only 9.5% of the subjects answered they know well about the sports drink they are drinking. To the 15 questions to survey the nutritional knowledge about fluid and intake of sports drink, subjects responded correctly to 58.47%. Their sex or experiences of nutrition education didn#t affect to their knowledge. As the result, the prevalence of collegiate athletes# sports drink use was high but their knowledge about it was not sufficient. These results suggest that an effective and practical nutrition education for adequate hydration and choice of sports drink for atheletes should be considered.

OBJECTIVES : Schizandra chinensis is well known for its efficacy at liver function reinforcement, relieving thirst and recovery from fatigue. In this study, we examined the effects of sports drink containing Schizandra chinensis on serum metabolic substrate, electrolyte, stress indicators, related-enzyme and exercise performance, rectal temperature, and heat shock proteinb70 (HSP70). METHODS : Elite long-distance runners (male, 21.3yrs, n=16) were selected and divided into two groups; an experimental group (EXP, n=8) and a control group (CON, n=8). A beverage containing Schizandra chinensis was supplemented 3 times per day to EXP for 4 weeks. Serum biochemical elements (glucose, lactate, total cholesterol, triglyceride, high density lipoprotein cholesterol, glutamate oxaloacetate transaminase, glutamate pyruvate transaminase, creatinine, creatine phosphokinase, lactate dehydrogenase, blood urea nitrogen, Na, K, Cl) were analyzed by auto blood analyzer. Exercise performance was measured by treadmill exercise test, HSP70 was detected by electrophoresis and Western blotting, and rectal temperature was measured by rectal temperature probe. RESULTS : Administration of the beverage increased significantly the rest level of blood Na, Cl and glucose and decreased significantly lactate dehydrogenase, glutamate oxaloacetate transaminase. No difference was found in exercise performance, rectal temperature increment or HSP70 concentration between groups. CONCLUSIONS : Administration of a sports drink containing Schizandra chinensis altered blood glucose, lactate dehydrogenase, glutamate oxaloacetate transaminase, Na and Cl levels.

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.
