摘　　要：模拟水球比赛参数研究不同负重条件下,不同游泳时间、不同训练次数对SD大鼠BHL、MHL、肌糖元、肝糖元变化的影响。结果与结论:(1)在SD大鼠12%负重游泳1-2分钟的运动训练中,递增负荷运动后A、B、C组血清BHL含量与前一组相比上升明显,具有非常显著性差异(P<0.01)。表明:该运动的能量代谢以乳酸增加为代表,并随着运动次数的不断增加,血乳酸与肌乳酸值不断增加。(2)在SD大鼠6%负重游泳16分钟的运动训练中,随着运动次数的增加,血乳酸逐步上升(p<0.05),肌糖原逐步减少(p<0.01),肝糖原没有明显变化,血糖呈下降趋势。表明该运动的能量代谢以糖有氧供能为主,并随着运动次数的不断增加,能量代谢逐步转化为以有氧为基础,糖酵解逐步增加的过程。Parameters of simulated water polo matches under the condition of different loads, different swimming time and frequencies are utilized to demonstrate their influences on SD rats＇BHL, MHL, muscle glycogen and liver glycogen, with the result and conclusion showing that： （1） In SD rats＇exercise of 1 -2 minute swimming with 12% load, the BHL in serum（ after increasing load exercise） of Groups A, B, C shows an obvious increase compared with the previous group, indicating remarkable differences（ P 〈 0.01 ）. This reveals that the energy metabolism of this exercise is characterized by the increase of lactic acid accompanied by the escalation of the value of blood and muscle lactic acid with the increase of the numbers of the exercise. （2） In SD rats＇exercise of 16 - minute swimming with 6% load, with the increase of the number of training, the blood lactic acid rises gradually （ p 〈 0.05） , the muscle glycogen gradually reduces （ p 〈 0.01 ） , the liver glycogen shows no significant change while the blood glucose shows a gradual drop. This shows that the energy metabolism of this exercise is mainly achieved by the aerobic oxidation of sugar. With the increase of the number of exercises, energy metabolism is gradually converted to an aerobic process with the glycolysis gradually increasing.
