新兵5km长跑对胃动力学和胃肠激素的影响

Influence of 5 km running on gastric kinetics and gastrointestinal hormone in new soldiers

目的 :观察 5km长跑对新兵胃动力及胃肠激素的影响 .方法 :采用实时超声和放免技术检测 4 8名新兵长跑前后的胃动力学指标和血浆胃动素 (MTL)、血管活性肠肽(VIP)和生长抑素 (SS)水平 .结果 :长跑后胃收缩次数减少(4.2± 1.2 )min-1,胃收缩幅度减低 (4.9± 2 .2 )cm2 ,胃排空率明显下降 (35 .7± 9.8) % .MTL含量 (10 8.4± 2 2 .2 )ng·L-1明显降低 ,VIP(2 4 .0± 2 .1)ng·L-1及SS(15 .8± 8.2 )ng·L-1明显升高 .结论 :新兵 5km长跑可使胃动力和胃肠激素水平发生变化 ,降低胃运动功能 .

AIM: To observe the effect of 5 km running on gastric motor and plasma levels of gastrointestinal hormones in new soldiers. METHODS: 48 soldiers before and after 5000 m running were studied, gastric emptying was determined with real time ultrasound, and plasma levels of motilin (MTL) vasoactive intestinal peptide (VIP) and somatostatin (SS) were measured with radioimmunoassay. RESUITS: Frequency (4.2±1.2) min -1 and amplitude of gastric contractions (4.9±2.2) cm 2 and gastric emptying (35.7±9.8)% were significantly decreased, and MTL level(108.4±22.2)ng·L -1 was markedly lower after running. VIP (24.0±2.1) ng·L -1 and SS (15.8±8.2) ng· L-1 levels were much higher after running. CONCLUSION: There were the gastric motor disorders in new soldiers after running 5 km and gastrointestinal hormones levels also changed.
