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 .
Objective: To observe the effect of 5km race on gastric motility and gastrointestinal hormones in recruits.Methods: The dynamic changes of gastric motility and plasma motilin (MTL), vasoactive intestinal peptide VIP, SS and so on.Results: The number of gastric contraction decreased (4.2 ± 1.2) min-1 after long-term running, the gastric contraction amplitude decreased (4.9 ± 2.2) cm2 and gastric emptying rate decreased obviously (35. 7 ± 9.8% .MTL content (10 8.4 ± 22.2) ng · L-1 was significantly lower in VIP group (24.0 ± 2.1 vs ng · L-1 and SS (15.8 ± 8.2) ng · L-1 was significantly increased.Conclusion: Recruits 5km long-distance running can change gastric motility and gastrointestinal hormone levels, reducing gastric motor function.
