【摘要】：目的研究大强度体能训练对战士身体机能变化的影响,为合理安排大强度体能训练提供依据。方法随机选择武警战士24名,测定和比较在一次大强度运动负荷下机体运动后和次日晨的生理生化指标变化。结果战士在大强度训练后,运动后即刻和次日晨主观体力感觉值较运动前增加114.5%和88.7%(P0.01);闪光融合频率值在运动后即刻和次日晨较运动前下降11.7%和17.2%(P0.01)。运动后即刻血尿素(BU)、肌酸肌酶(CK)和乳酸脱氢酶(LDH)水平较运动前分别增加35.9%、107.4%和67.0%(P0.01);BU次日晨恢复值有所下降但仍高于安静值(P0.05),CK和LDH次日晨恢复值继续上升。结论采用生物化学手段能客观、准确地说明一次大强度体能训练对战士身体机能形成较大的刺激,可作为进一步负荷安排的依据。
[Abstract]:Objective to study the effect of high intensity physical training on the changes of soldiers' physical function, and to provide the basis for rational arrangement of high intensity physical fitness training. Methods Twenty-four armed police soldiers were randomly selected to measure and compare the changes of physiological and biochemical indexes after exercise and the next morning under a heavy exercise load. Results after intensive training, the subjective physical sensory values of soldiers immediately after exercise and in the next morning increased by 114.5% and 88.7% (P0.01) compared with those before exercise. The frequency of flash fusion decreased by 11.7% and 17.2% immediately after exercise and in the morning after exercise (P0.01). Immediately after exercise, the levels of blood urea (BU), creatine enzyme (CK) and lactate dehydrogenase (LDH) increased by 35.9% and 67.0% respectively (P0.01) compared with those before exercise. The recovery value of BU decreased a little the next morning but still higher than the quiet value (P0.05), CK and LDH recovery value continued to rise the next morning. Conclusion the biochemical method can objectively and accurately explain that a large intensity physical training can stimulate the body function of soldiers, which can be used as the basis for further load arrangement.
