摘要
背景:运动过程中会引起水和电解质丢失,使神经传递速度减慢,导致肌肉运动能力下降。补充电解质可以防止机体免疫功能下降,有利于维持体液平衡和乳酸消除。目的:观察中学生进行一次体能训练时补充糖-电解质运动复合处方对血液中电解质Na+,K+,Ca2+含量变化及体液丢失的影响。设计、时间及地点:随机对照观察,于2007-08在宜宾市四中完成。对象:选择高二男生16名,按随机数字表法分为2组,纯净水组、运动复合处方组各8名。方法:两组同时进行体能训练。纯净水组学生运动前后每人共补充400mL纯净水,运动复合处方组学生补充400mL糖-电解质运动复合处方。主要观察指标:观察两组学生训练前及训练后20min血样电解质变化及体液丢失情况。结果:①与运动前相比,两组学生运动后血液中的K+含量都有明显增加(P<0.05);运动复合处方组的Na+,Ca2+运动后有明显增加(P<0.05,0.01)。②与运动复合处方组相比,纯净水组体液丢失更加明显。结论:补充糖-电解质运动复合处方能提高血液中的电解质含量,减少体液丢失。
BACKGROUND： Water and electrolyte loss in the sport process leads to neurotransmission speed and kinetism decrease. Electrolyte supplement can prevent immune function decrease and is benefit for maintaining fluid balance and eliminating lactic acid. OBJECTIVE： To observe the effect of Glucose-electrolyte sport prescription on the blood Na^＋, K^＋, Ca^2＋ change and body fluid loss in one-trial physical ability training of high school students DESIGN, TIME AND SETTING： A randomized controlled observation was done at the Fourth High School of Yibin in August 2007. PARTICIPANTS： Sixteen boys from Grade 2 were divided into purified water group and sport prescription group by random digit table, with 8 boys in each group. METHODS： The 16 students did physical ability training at the same time. Students in the purified water group totally supplemented 400 mL purified water before and after the training, while students in the sport prescription group supplemented 400 mL glucose-electrolyte sport prescription. MAIN OUTCOME MEASURES： Blood electrolyte change and body fluid loss condition before the training and 20 minutes after the training. RESULTS： Compared with that before the training, K^＋ content in the blood increased significantly after the training in both groups （P 〈 0.05）; Na^＋ content and Ca^2＋ content increased markedly after the training in the sport prescription group （P 〈 0.05, 0.01）. Body fluid loss was more significant in the purified water group than in the sport prescription group. CONCLUSION： Glucose-electrolyte sport prescription supplement can increase the electrolyte content in the blood and decrease body fluid loss.
