摘　　要：研究目的:探讨间歇性无氧运动后血清乳酸值对Ca2+浓度变化的影响。研究方法:对健康雄性SD大鼠施以间歇性无氧运动干预,然后采用半自动生化分析仪测定血乳酸值和钙离子含量,分析间歇性无氧运动中血乳酸值对骨骼肌胞浆钙稳态的影响。结果:短间歇组与对照组相比,运动后1小时,大鼠血乳酸值有升高的趋势,血清总钙变化幅度不明显,血清游离钙有下降的趋势;运动后24小时,血乳酸值有显著性差异,血清总钙有明显差异,血清游离钙有极显著性差异;运动后48小时,血乳酸值没有显著性差异,血清总钙、血清游离钙的差异仍然存在;长间歇组则无显著性差异。结论:间歇运动可使肌浆网和线粒体转运Ca2+能力下降,并使胞浆Ca2+聚积,进而导致骨骼肌疲劳。Objective： To investigate the effect of serum lactate value on Ca2＋ concentration changes after intermittent anaerobic exercise,which has theoretical significance of the formation mechanism of exercise-induced fatigue. Methods： Healthy male SD rats were subjected to intermittent anaerobic exercise; by adopting semi-automatic biochemical analyzer to determine blood lactate and the content of calcium ion,analyze the influence of blood lactate values in intermittent anaerobic exercise on skeletal muscle cytosolic calcium homeostasis. Results：Compare short intermittent group with the control group,one hour after exercise,rat blood lactate values are increasing trend,the magnitude of serum total calcium has no significant change,serum free calcium has declined;24 hours after exercise,blood lactate values are significantly different,there are significant differences in total serum calcium and serum free calcium; 48 hours after exercise,there was no significant difference in blood lactate,there are differences in total serum calcium and serum free calcium; long intermittent group has no significant difference. The conclusion is that exercise makes the sarcoplasmic reticulum and mitochondria Ca2 ＋transport capacity decline and makes cytosolic Ca2＋ accumulate,leading to skeletal muscle fatigue.
