目前国内沿用的血清肌酸激酶同工酶(CK:EC2,7,3,2)正常值,都以国外文献值为基准。此同工酶活性与人种,性别及年龄有关,当前我国青少年运动员数量日增,加之流行病学资料反映冠心病发病年龄有提前倾向,故收集资料计算出我国青少年血清CK同工酶参考值,供运动科学研究及临床诊断参考有现实意义。 本组以115名长沙地区中学生为测试对象,男55名,女60名,年龄13～17岁。均经ECG检查及体检正常,且无伤痛者。剔除12名(男8,女5)在一周内曾参加剧烈运动,每日骑自行车半小时以上及曾 Current domestic use of serum creatine kinase isoenzyme (CK: EC2,7,3,2) normal values ​​are based on foreign literature as a benchmark. This isoenzyme activity is related to ethnicity, sex and age. At present, the number of adolescent athletes in China is increasing day by day. In addition, the epidemiological data indicate that the age of onset of coronary heart disease has a proactive trend. Therefore, the data of juvenile serum CK isozymes were collected , For sports science research and clinical diagnostic reference has practical significance. The group of 115 middle school students in Changsha as the test object, 55 men and 60 women, aged 13 to 17 years. All were normal ECG examination and physical examination, and no pain. Excluding 12 (male 8, female 5) in a week have participated in strenuous exercise, cycling more than half an hour a day and had
