The Effect ofSports Drink Including Red Ginseng and Electrolytes on the Performance Related Physiological Factors in Elite Hockey Players
Abstract
This study was designed to investigate the effects of sports drink including red ginseng and electrolytes in elite hockey players. The first purpose of this study was to evaluate the sports drink on water balance(Hct, osmolality, Na+, K, Cl-, and Mg), aerobic energy production(blood glucose, FFA) and recovery(HR, body temperature, lactate) after intaking the spurts drink. The second purpose was to compare it with sports drink including electrolytes and drinking water. The last of this was a sensory test on red ginseng sports drink The subjects were 12 elite hockey players and they were divided into group A(water intake right after exercise), group B(electrolytes sports drink intake right after exercise), group C(red ginseng sports drink right after exercise), group D(electrolytes sports drink intake before and after exercise), group E(red ginseng sports drink intake before and after exercise). All subjects were performed maximal treadmill exercise test to exhaustion. After 30 minutes of submaximal running at 70-75%VO_2 max preceded 4 minutes warm up. On the basis of the results in this study, the conclusions were below: Group E(216.0±23.3sec) continued significantly longer time than group D(172.0±41.2sec) in exercise durable time after sweating loss. Group E showed significantly higher values than group D in vo_2 max at all-out/VO_2 max ratio, Group D and group E were slightly lower than group A and group B in the level of blood glucose during exercise. Group B, C, D, and E showed significant differences in the level of blood glucose during recovery. The changes of heart rate and body temperature showed no significant difference between each group. Group E showed higher blood lactate(BLA) than group D at the exhauston. After 15 minutes of recovery, the level of BLA were same in all groups. Hct, osmolality, Na+, K, Cl-, Mg, and FFA) did not show any significant difference between each group. This results suggest that red ginseng and electrolytes included sports drink may contribute to improve the exercise performance and to help recovery after exercise.
