THE INFLUENCE OF FOOD LOADING WITH VITAMIN AND ELECTROLYTE ON PHYSICAL INDEX OF ATHLETES.

During the training of athletes, weight reduction and stamina recovery is an important trial of athletic contest. This paper systematically studies the interference of food such as functional drinks, vegetables, meat, eggs to somatic function when on weight reduction. This paper researches the influence of nutriology intervene on the blood index of athletes during slow weight reduction in training, fast weight reduction before the competition and stamina restoring ahead the competition. Twelve athletes of female weight lifting team were selected and divided into experimental group and control group, each with 6 athletes. Athletes of both groups took the same exercise training and diet with same energy. And compared with control group, the experimental group took slim bar and sports nutrition with electrolyte during weight reduction; and strengthened the sports nutrition with fast energy supplement preparations, vitamin and electrolyte during the stamina restoring stage while the control group took relevant placebo. Both groups received blood detection. The results suggested that creatine kinase and blood urea of experimental group during fast restoring stage was much lower than control group; the hemoglobin was higher than control group and the testosterone of both groups were with no difference. The concentration of serum potassium, sodium and calcium of experimental group during the fast weight reduction and restoring stage was distinctly higher than control group. The hunger degree of experimental group during weight reduction stage was lower than control group. Thus we reached the conclusion that the nutritious food intervene can help reduce weight and has fine hemoglobin level, serum creatine kinase level and serum inorganic ion level. This method can maintain the steadiness of internal environment of athletes during weight reduction. [ABSTRACT FROM AUTHOR]
