改良版八段锦对战士体能训练成绩的影响

Effect of revised version of Ba Duan Jin exercise on physical fitness in soldiers

目的探讨改良版"八段锦"对战士体能训练成绩的影响。方法2019年10-12月选取驻京某部战士65名,男性,平均年龄20.7岁。其中45名无慢性病、训练伤的战士在训练成绩稳定后,进行常规体能训练与改良版八段锦训练各4周,比较两种训练方式提高体能成绩的差异;另20名患有慢性病、训练伤的战士行改良版八段锦练习,观察其对战士常见慢性病及训练伤的影响。结果常规体能训练4周后,各项考核成绩几乎没有提高,仅引体向上数量较训练前平均增加1.07±1.75个,差异有统计学意义(P=0.000)。继续改良八段锦训练4周后,各项成绩提高程度优于常规体能训练:30 m往返跑[(0.33±0.22)s vs(0.02±0.21)s]、3000 m跑[(0.43±0.34)min vs(-0.02±0.19)min]、引体向上[(2.60±1.24)个vs(1.07±1.75)个]差异均有统计学意义(P均<0.05)。患慢性疾病的20名战士坚持练习4周后,主观症状改善率达到65%,其中自觉明显改善占55%。结论练习改良八段锦可提高战士体能训练成绩,改善慢性疾病状态,值得在部队推广。

Objective To examine the effect of revised version of Ba Duan Jin exercise on the physical fitness of soldiers.Methods In October 2019,we recruited 45 male soldiers from a troop in Beijing to participate our training program.The program was divided into 2 stages:stage 1 was for regular training program(4 weeks),and stage 2 was for revised version of Ba Duan Jin exercise(4 weeks).The soldiers’physical fitness test results were compared between the two stages.Another 20 solidiers with chronic diseases or injuries were also invited to practice revised version of Ba Duan Jin for 4 weeks,and their symptom improvement was recorded.Results After 4 weeks of regular training,there was little improvement in physical fitness,and only the number of pull-up increased by 1.07±1.75 with significant difference(P=0.000).Then,after 4 weeks of Ba Duan Jin exercise,there were statistically significant increases in 3-mile military run,30 m shuttle run,and pull-up(all P<0.05),and the improvements in stage 2 were significantly higher than those in stage 1(3-mile military run,[0.43±0.34]min vs[-0.02±0.19]min);30 m shuttle run,[0.33±0.22]s vs[0.02±0.21]s;pull-up,[2.60±1.24]vs[1.07±1.75];P<0.05,respectively.The subjective improvement rate of symptoms in 20 soldiers suffering from chronic diseases or injuries reached 65%after 4 weeks’practice,and 55%of them felt obvious improvement.Conclusion The revised version of Ba Duan Jin exercise has a favourable effect on the physical fitness of soldiers,and improves the condition of chronic diseases,which is worthy of popularization in the army.
