Abstract

Research purpose sports training process, with sweat discharge, loss of water and electrolytes will destroy the body's balance of water and salt metabolism, athlete's athletic ability will be varying degrees of decline. Collected in the process of sports training athletes sweat concentration determination of sodium, potassium, chloride, calcium, compare different gender, different athletes sweat ion concentration differences and sweat ion concentration as the basis of sports rehydration. The aim is to maintain the balance of the athlete of water and salt metabolism, maintain a good functional status and exercise capacity, excellent competition results provide protection for athletes. Research methods for male athlete of the Shanghai Institute of Physical Education, Shanghai subsidiary of competitive sports school Sanda team to participate in National Wushu Sanshou Championship four, aged 20 to 27 years old; eight female athletes, aged 18 to 23 years old, are sports training level above the level of the national elite athletes. Male athlete of competitive sports school middle-distance team of eight, aged 13 to 18 years old; five female athletes, aged 17 to 20 years old. The first stage of the experiment: the sweat collected and the ion concentration measurement. Plastic film with homemade paste \The second phase of the experiment: the assessment the supplement and effect of electrolyte sports drinks. Sports drink formulated based on the detection result of the ion concentration of athletes sweat, balanced salt, lactated Ringer's solution and boiled for raw materials, the preparation of the electrolyte sports drink. Monday morning, 6:00 in the first week of blood, blood indicators will be measured as the basis of assessment of the control of rehydration effect. Then month-electrolyte sports drink supplement, 800ml homemade drinks daily for athletes during training (Monday to Saturday). Monday morning, 6:00 in the fourth week of blood, blood biochemical indicators will be measured. , Analysis by comparison with the test results of the first week before the rehydration electrolyte sports drink supplement on the impact of the athletes ion metabolism and water metabolism, supplementary effect on the rating of the sports drink. The test indicators including serum sodium ion concentration (CNa), the concentration of potassium ions (CK), the concentration of chloride ions (CCl-), calcium (CCa2), hematocrit. Data mean and standard deviation. Independent samples t-test and paired t-test analysis of the measured data using Excel 2003 and SPSS 13.0 statistical software. P lt; 0.05 to determine significant difference. The results of the findings show that discharged from the preparatory activities to within 50 minutes of training, the two parts of the left chest and right upper back sweat ion concentration (mean ± standard deviation): sodium ion concentration 56.88 ± 26.36mmol / L The chloride ion concentration 52.03 ± 22.98mmol / L, potassium ion concentration of 6.71 ± 3.75mmol / L, the calcium ion concentration of 0.54 ± 0.27mmol / L,. The sodium ion concentration in the electrolyte sports drink formulated balanced salt, sodium lactate Green's solution as raw 58.68mmol / L, chlorine ion concentration was 50.52 mmol / L, potassium ion concentration of 5.81 mmol / L, the calcium ion concentration of 0.56 mmol / L. Electrolyte sports drink formulated athletes training lost during sweat ion concentration. Study found that different gender, different athletes sweat potassium ion concentration differences, but taking into account the operability of the experiment, the body of water and salt metabolism, the role of automatic adjustment mechanism and diet, only sweat ion concentration average preparation of an electrolyte drink . Electrolyte sports drink supplement the athletes blood indicators compared to the first week of the fourth week, sodium, chlorine, calcium ion concentration has increased, the potassium ion concentration decreased slightly, there was no significant difference in sex (P gt; 0.05) . And overcome the occurrence of the the hypernatremia phenomenon under serum ion concentration changes in the basis of preparation of electrolyte drinks rehydration, has provided a guarantee for the Sanda athletes control weight during the balance of water and salt metabolism in the body. The blood hematocrit changes before and after rehydration little was no significant difference in sex (P gt; 0.05) in the test serum ion concentration, hemoconcentration or dilution phenomenon does not exist. Training a lot of perspiration during the case, remained stable after electrolyte sports drink supplement athletes ion balance and water balance. Conclusion plastic film affixed to sweat collection technique is simple, the athletes training process effectively collect sweat dope different parts of the collection, according to the motion characteristics of the sport. 2. Electrolyte sports drink formulated based on athletes during training sweat ion concentration to ensure relatively constant ion concentration in athletes during training to achieve the purpose of rehydration. 3 formulated electrolyte sports drinks according sweat ion concentration to overcome the phenomenon hypernatremia after rehydration serum ion concentration changes. Rehydration before and after the athletes blood ion balance and water balance stable, maintain a relative balance of the athletes water and salt metabolism.
