【摘要】： 目的探求一种适合常规部队、能快速有效提高士兵有氧耐力素质的训练方法,并降低由此而所致军事训练伤的发生率。以及探讨依据“循环训练法[1]”理念设计的耐力强化训练方法对具有不同血管紧张素转换酶基因(ACE)特征士兵的有氧耐力素质提高的影响。方法随机抽取某步兵团248名无军事训练史的汉族男性新兵,均分成两组,一组为实验组,采用以“循环训练法”〔1〕为理念设计的强化耐力训练方法;一组为对照组,采用部队常用耐力训练方法,即以5000m跑为主的训练方法,每周5000m×3次,每日不超过1次,两组总共进行8周的耐力素质训练。训练开始前和训练8周后分别测试战士的安静脉搏,肺活量,VO2max和5000m成绩等耐力素质指标。并于训练8周后对战士进行体检,检测有小腿肿胀和按压痛症状、膝关节肿痛以及下腰痛等军事训练伤发生人数,统计军事训练伤发生率。然后通过检测两组士兵的ACE基因亚型,并在各组内按照不同基因分型再分为II、ID、DD型三组,根据相应训练绩效分析训练方法对具有不同ACE基因分型士兵耐力素质的影响。结果实验组训练后安静脉搏降低了8.0%,肺活量、VO2max、5000m成绩较训练前分别提高了8.1%、20.0%和14.7% ( P 0. 01)。两组间绩效比较有显著差异(P0.05),实验组训练伤发生率为3.3%,对照组训练伤发生率为8.1%,两组间训练伤发生率有显著差异(P0.05)。两组战士的基因多态位点均符合Hardy-Weinberg平衡。试验组ACE基因分型中, II型占33.9%,ID型占59.6%,DD型占6.5%。对照组II型占46.8%,ID型占50.0%,DD型占3.2%。试验组中的ID型和DD型的5000m成绩和VO2max较对照组中的II型的仍有显著提高,差异有统计学意义(P0.05)。实验组组内各ACE基因型之间比较均无明显差异(P0.05)。对照组中II型和ID型之间无显著差异(P0.05),DD型和II型、ID型有显著差异(P0.05)。实验组训练后VO2max、5000m跑成绩较训练前显著提高20. 0 %和14. 7 %( P 0. 01),并且较对照组显著提高(p0.05)。结论以“循环训练法”为理念设计的强化耐力训练方法可有效提高部队战士耐力素质并减少军事训练伤的发生。在相同训练条件下,以“循环训练法”理念设计的强化耐力训练方法可以有效提高士兵耐力素质;不同ACE基因型不能确切作为士兵耐力素质好坏和提升速度快慢的指标。
[Abstract]:Objective to explore a training method suitable for conventional troops, which can improve the aerobic endurance quality of soldiers quickly and effectively, and reduce the incidence of military training injuries caused by it. [1) "the effect of the method of intensive endurance training designed by the idea on the improvement of aerobic endurance quality of soldiers with different angiotensin converting enzyme gene (ACE) characteristics. Methods A total of 248 male recruits of Han nationality without military training history were randomly selected and divided into two groups. One group was used as the experimental group and the method of intensive endurance training was designed with the idea of "cyclic training method". One group was used as the control group. The common endurance training method was 5000m running, 5000m 脳 3 times a week, no more than once a day. The two groups received a total of 8 weeks of endurance quality training. Before and after 8 weeks of training, the silent pulse and vital capacity of the soldiers were tested. After 8 weeks of training, the soldiers were examined for the symptoms of swelling and pressing pain of the lower leg. The incidence of military training injuries such as swelling and pain of knee joint and lower back pain were counted. Then the ACE gene subtypes of the two groups were detected and subdivided into two groups according to different genotypes. According to the corresponding training performance analysis, the three groups of IDDD-type had an effect on the endurance quality of soldiers with different ACE genotyping. Results after training, the quiet pulse of the experimental group was decreased by 8.0 and the VV _ 2max-5000m score was increased by 8.1% compared with that before training. There was a significant difference between the two groups in the performance of the two groups (P 0.05), and the incidence of training injury in the experimental group was 3.3%. The incidence of training injury in the control group was 8.1%. There was significant difference in the incidence of training injury between the two groups (P 0.05). The polymorphic loci of the two groups were in accordance with the Hardy-Weinberg balance. In the ACE genotyping of the experimental group. Type II accounted for 33.9% and ID type 59.6%, DD type 6.5 and control group II 46.8% and ID type 50.0%. The scores of ID type and DD type 5000m and VO2max in the trial group were significantly higher than those in the control group. The difference was statistically significant (P 0.05). There was no significant difference among all ACE genotypes in the experimental group, but there was no significant difference between the type II and the ID type in the control group (P < 0.05). P0.05). There was significant difference between DD type and type II type ID. VO2max was found in the experimental group after training. The results of 5000m race were significantly increased by 200.0% and 14.7% (P < 0.01) than those before training, and significantly increased compared with the control group (P < 0.01). Conclusion the method of intensive endurance training designed with the idea of "cycle training method" can effectively improve the endurance quality of soldiers and reduce the incidence of military training injuries under the same training conditions. The method of intensive endurance training designed with the idea of "cycle training method" can effectively improve the endurance quality of soldiers. Different ACE genotypes can not be used as an index of endurance quality and speed of improvement.
