将山东省普通中学体育传统项目学校400m跑少年男子运动员36名,按条件对等原则分为对照组、)外,再增服不同剂量的一般实验组、强化实验组、超强实验组。对实验各组除日口服同剂量的维生素B1(VB1维生素C(Vc),对照组不加服维生素。2周后按竞赛规则要求,分别对四组运动员进行400m成绩测定,同时测定400m运动前相对安静、运动后即刻及休息30min后血乳酸浓度。实验结果提示:运动后,强化实验组运动员血乳酸水平和运动成绩与该组实验前及对照组比较均有显著差异(P<0.05)。表明:400m跑少年运60mg,可使运动后血乳酸下降明显,运动成绩有所提高,恢复过程动员短时程(2～3周)日补充Vc300mg,VB1明显加快。);400m;血乳酸;少年运动员
Thirty-six of the 400m young male athletes in the 400m run-of-age traditional sports schools of ordinary middle schools in Shandong Province were divided into two groups according to the principle of equal treatment. The general experimental group with different dosages was additionally served with intensified experimental group and super-experimental group. Vitamins B1 (VB1 vitamin C (Vc)) were administered orally to the experimental groups with the same dose of vitamin B1 (VB1) and no vitamins in the control group.After 2 weeks, according to the rules of the competition, 400m scores were determined for the four groups of athletes, (P <0.05) .Conclusion: After exercise, blood lactate levels and exercise scores of athletes in experimental group were significantly different from those in experimental group and control group (P <0.05). The results showed that: 400mg run juvenile transport 60mg, can make the blood lactate decreased significantly after exercise, exercise performance improved, the recovery process mobilization short-term (2 to 3 weeks) added V300mg, VB1 significantly accelerated.); 400m; Teenager athlete
