【摘要】：本文采用运动生物化学的实验方法,对芭蕾舞学生基训课后以及基训课中各组训练后的血乳酸、血尿素等指标进行了测试。研究结果表明:芭蕾舞基训课后血乳酸水平显著提高,代谢类型属于有氧无氧混合型。芭蕾基训课各组训练的负荷强度不同,能量代谢类型也不同,中跳和大跳训练的强度相对较大,其次是把杆,小跳和中间部分的训练强度相对较小;把杆、中间和小跳训练的供能系统以有氧代谢供能为主,而中跳和大跳训练以糖酵解供能为主。芭蕾舞基训后血尿素值升高,说明蛋白质参与了代谢供能,但升高幅度大约为1mmol/L左右,说明芭蕾基训的运动量中等,而且血尿素测定结果说明训练后能够得到恢复。研究建议:注重发展芭蕾舞学生的有氧代谢能力和无氧代谢能力;芭蕾舞学生在基训课上还有负荷潜力,可以加大训练量;芭蕾舞学生不可忽视蛋白质的补充。
[Abstract]:In this paper, the indexes of blood lactic acid and blood urea of ballet students after basic training and training in each group were tested by the method of exercise biochemistry. The results showed that the level of blood lactic acid increased significantly after basic ballet training, and the metabolic type belonged to aerobic anaerobic mixed type. The training intensity of each group of ballet basic training class is different, the energy metabolism type is also different, the training intensity of medium jump and big jump is relatively large, the second is the training intensity of handle, small jump and middle part is relatively small; The energy supply system of middle and small jump training is mainly aerobic metabolism energy supply, while middle jump and large jump training is mainly glycolytic energy supply. The increase of blood urea value after ballet training indicated that protein was involved in metabolic energy supply, but the range of increase was about 1mmol/L, which indicated that the amount of exercise in ballet training was moderate, and the blood urea test showed that the blood urea could be recovered after training. The study suggests that attention should be paid to the development of aerobic and anaerobic metabolism of ballet students; that ballet students have the potential of loading in basic training classes, which can increase the amount of training; and that ballet students should not ignore the supplement of protein.
