摘　　要：为探讨12乳酸阈强度训练对特警战士心肺机能的影响,确定乳酸阈强度所对应的心率值,招募16名新入伍特警战士,分为实验组(8人)进行12周的乳酸阈强度训练,对照组(8人)按原特警部队训练任务训练。测试训练前后身体形态、身体成分、心肺机能、3 km测试的变化,并在递增负荷运动过程中测定受试者的血乳酸值,测试过程中使用芬兰产POLAR遥测心率表带获取受试者乳酸阈强度所对应心率。12周乳酸阈强度训练后,受试者的身体成分、心肺机能均有显著性提高;乳酸阈的值为(3.68±0.64)mmol/L,对应的强度为(9.42±0.78)km/h,乳酸阈强度所对应的心率为(151±13.5)b/min。实验结果显示,12周乳酸阈强度训练能够显著提高特警战士的心肺机能,同时降低训练伤病;(151±13.5)b/min的心率可作为特警战士乳酸阈强度训练的参考。To explore the influence of 12 lactate threshold intensity training on the cardiopulmonary function of special police soldiers,and determine the heart rate value corresponding to the lactate threshold intensity,16 newly enlisted special police soldiers were recruited and divided into experimental group(8 people)for 12 weeks of lactate threshold intensity training,and control group(8 people)for training according to the training task of the original special police force.The changes in body shape,body composition,cardiopulmonary function,3km test before and after training were tested,and the blood lactate value of the subjects were measured during the incremental load exercise.During the test,the Finland-made POLAR telemetric heart rate watch was used to obtain the lactate threshold intensity of the subjects.After 12 weeks of lactate threshold intensity training,the body composition and cardiopulmonary function of the subjects were significantly improved.The value of lactate threshold was 3.68±0.64mmol/L,the corresponding intensity was 9.42±0.78 km/h,and the corresponding heart rate was 151±13.5b/min.The experimental results show that the 12-week lactate threshold intensity training can significantly improve the cardiopulmonary function of special police soldiers while reducing training injuries.The heart rate of 151±13.5b/min can be used as a reference for the lactate threshold intensity training of special police soldiers.
