【摘要】：目的评价踝关节强化训练对士兵踝关节肌力的影响,找到合适的、能快速提高训练成绩的训练方法。方法随机挑选新入伍的士兵和第二年度兵各30名,并对新兵专门添加为期8周的踝关节背伸、跖屈、内外翻的肌力强化训练,然后采用CYBEX-6000型等速测试训练系统分别对训练前、强化训练8周时的新兵和第二年度兵进行踝关节肌力等速测试和跟腱横截面积测量。结果新兵训练前、强化训练8周后、第二年度士兵的跟腱横截面积(分别为0·64±0·05cm2、0·67±0·07cm2、0·65±0·07cm2)与体重呈正相关(r=0·446),消除体重因素后,各组间无明显差异(P=0·698,F=0·361);训练前的踝关节背伸、跖屈、内外翻的峰力矩、力矩加速能、耐力、屈伸峰力矩之比等指标均明显低于强化训练8周组和第二年度士兵组(P0·05或0·01)而强化组和第二年度兵组之间无明显差异(P0·05)。结论新兵8周强化训练能取得与经常规训练的第二年度兵接近的效果,即强化训练可以在短期内快速促进体能储备,从而提高训练成绩;训练后跟腱截面积无明显变化,提示踝关节肌力的提高不是通过肌腱肥大实现的,而与肌腱的功能结构塑形改建有关。
[Abstract]:Objective to evaluate the effect of ankle joint intensive training on ankle muscle strength of soldiers, and to find a suitable training method that can improve the training performance quickly. Methods 30 new recruits and 30 soldiers of the second year were randomly selected. And the recruits were specially added for 8 weeks of ankle extension, metatarsal flexion, varus muscle strength intensive training, and then use the CYBEX-6000 type isokinetic test training system before training respectively. After 8 weeks of intensive training, the strength of ankle joint and the cross sectional area of Achilles tendon were measured in the recruits and the soldiers of the second year. Results before and after 8 weeks of intensive training, the strength of the ankle joint and the area of the Achilles tendon were measured. The cross-sectional area of Achilles tendon was 0.64 卤0.05cm ~ 2 (0.67 卤0.07 cm ~ 2) in the second year. 0.65 卤0.07 cm ~ (2) was positively correlated with body weight (P < 0.01). After eliminating weight factors, there was no significant difference between the groups. Ankle extension, metatarsal flexion, peak torque, torque acceleration, endurance before training. The ratio of peak moment of flexion and extension was significantly lower than that of the 8-week intensive training group and the second year soldier group (P 0.05 or 0.01), but there was no significant difference between the reinforcement group and the second year soldier group (P 0.05). Conclusion the result of 8 weeks intensive training of recruits is close to that of the second year soldiers trained by routine training. That is, intensive training can quickly promote the physical reserve in the short term, thereby improving the training results; After training, there was no obvious change in the area of Achilles tendon cross-section, which suggested that the increase of ankle muscle strength was not achieved by tendon hypertrophy, but was related to the remodeling of the functional structure of the tendon.

【正文快照】： 体能训练是体能储备的根本保证,繁重的体能训练以及各种训练伤是参训官兵必须面对的问题。强化循环训练法[1]可以较快速地促进骨骼的塑形改建,减少应力骨折的发生;同样也可能促进肌腱、肌肉等的塑形改建,快速提高训练成绩。本研究的目的是探讨强化训练对踝关节肌力和跟腱横截
