目的了解不同强度长跑对青年军人速度知觉的影响。方法随机抽取我国某军校88名青年军人,分为试验组和对照组,其中69人为3 000 m组,59人为6 000 m组。采用组间设计和组内设计,研究3 000 m跑和6 000 m跑对军校新学员速度知觉的影响情况。结果 3 000 m跑实验:实验组与对照组之间差异没有统计学意义(P>0.05);跑步前测差异、后测差异均无统计学意义(P>0.05)。6 000 m跑实验:试验组和对照组之间跑步后测差异有统计学意义(t=5.99,P<0.01),跑步前测差异无统计学意义(P>0.05)。试验组跑步前、后测差异有统计学意义(t=-3.70,P<0.01);对照组跑步前、后测差异无统计学意义(t=0.68,P>0.05)。结论对于军校新学员,3 000 m跑对其的速度知觉无显著影响,6 000 m跑对其速度知觉有一定影响,因此,在进行体能训练时应遵循科学的、循序渐进的原则。
Objective To understand the effects of different intensity long-distance running on the speed perception of young soldiers. Methods A total of 88 young military personnel from a certain military school in our country were randomly divided into experimental group and control group, of whom 69 were 3 000 m and 59 were 6 000 m. The inter-group design and in-group design were used to study the influence of 3 000 m and 6 000 m on the speed perception of new cadets. Results 3 000 m run test: There was no significant difference between the experimental group and the control group (P> 0.05). There was no significant difference between the pre-test and the post-test (P> 0.05). 6 000 m running test: The difference between the test group and the control group after running was statistically significant (t = 5.99, P <0.01). There was no significant difference before running (P> 0.05). The difference between the two groups before and after running was statistically significant (t = -3.70, P <0.01). There was no significant difference in the control group before and after running (t = 0.68, P> 0.05). Conclusion For the new military cadets, the 3 000 m run had no significant effect on their speed perception and the 6 000 m run had some influence on their speed perception. Therefore, they should follow the scientific and gradual principle in physical training.
