我们以前的研究工作表明，牛磺酸对运动机体可发挥有效的保护作用。为探讨这一保护作用能否提高运动能力，我们观察了分别给予牛磺酸和丙氨酸（可耗竭体内的牛磺酸）后大鼠运动能力和全血粘度的变化。结果发现：运动后大鼠的运动能力较对照组显著增加，牛磺酸使运动大鼠的运动能力进一步增加，而丙氨酸则使运动大鼠的运动能力下降到与对照组无明显差异。给予丙氨酸的运动大鼠，其全血粘度在高、低切变率上都显著增加，给予牛磺酸后，其全血粘度无明显变化，红细胞压积与给予丙氨酸组比较显著降低，与对照组则无差别。以上结果表明：体内牛磺酸对维持运动能力是必需的，外界给予则可使其运动能力进一步增加，这可能与其对血液流变特性的调节有关。
Our previous research shows that taurine can exert an effective protective effect on the motor body. To investigate whether this protective effect improves exercise capacity, we observed changes in locomotor capacity and whole blood viscosity in rats given taurine and alanine, respectively, which can be depleted of taurine. The results showed that: after exercise, the exercise capacity of rats increased significantly compared with that of the control group. Taurine increased the exercise capacity of exercise-induced rats, while that of alanine decreased the exercise capacity of exercise-induced rats compared with the control group. The alanine exercise rats, the whole blood viscosity in the high and low shear rates were significantly increased, given taurine, no significant changes in the whole blood viscosity, hematocrit and given alanine group was significantly Lower, no difference with the control group. The above results show that taurine in the body is necessary for maintaining exercise capacity, and the external exercise can further increase its exercise capacity, which may be related to the regulation of the blood rheological properties.
