摘要
目的 探讨不同地区青年耐寒锻炼前后体能状态及冷适应能力变化情况,为按照新兵训练大纲施训提供科学依据。方法 随机选择黑龙江某部队来自寒区和非寒区的应征新兵各5 0人,分成2组,Ⅰ组(寒区新兵) ,Ⅱ组(非寒区新兵) ,于2 0 0 2年12月～2 0 0 3年2月按照新兵训练大纲内容进行耐寒锻炼,分别于训练前、训练3 0d、训练60d测定受试者的心率及PWC170 “次极限负荷”试验变化。结果 两组新兵的基础心率在训练各时段比较,差异均无显著性(P >0 . 0 5 )。Ⅰ、Ⅱ组组内比较,其第1次负荷后、第2次负荷后心率与基础心率的差值,以及PWC170 在训练3 0d、训练60d与新兵训练前比较以及在训练60d与训练3 0d比较,差异均有非常显著性(P <0 .0 1)。Ⅰ、Ⅱ组组间比较,在训练各时段,其第1次负荷后心率、第2次负荷后心率、2次负荷后心率的差值及PWC170 差异均无显著性(P >0 .0 5 )。结论 对来自不同地区的应征青年按照新训大纲实施耐寒锻炼,其体能明显增强,冷适应能力显著提高。
Objective To study the physical status and cold adaptive ability of the young men from different regions during cold tolerance training. [M ethods] 5 0 newly recruited soldiers from either cold regions or warm regions were randoml y selected and divided into 2 groups: group Ⅰ (from cold regions) and group Ⅱ (from warm regions). Both the two groups received military cold tolerance traini ng from Dec. 2002 to Feb. 2003. Their heart rates and Physical Work Capacity (PW C 170) were tested before training, 30 days after training and 60 days afte r tra ining. [Results] No significant difference was found in the ba sic heart rate of t he two groups in different periods (P>0.05). The comparison within groups sh owed significant difference between the basic heart rate and the heart rate after ph ysical burden, the same as PWC 170 (P<0.01). No significant difference was found in the comparison between groups (P>0.05). [Conclusion] Military cold toleranc e training for the newly recruited young men can significantly help improving th eir physical strength and cold adaptive ability.
