Experimental Study On The Effect Of Non-steady-state Strength Training On The Agility Of High School Male Football Player

Background:In soccer games,players often change direction in high-speed movement,stop and start sharply during the change of attack and defense,change direction,and collide and confront each other when fighting for the ball,soccer players often leave the support surface when doing these actions,and the body is often in a non-stable state.However,this is often overlooked when developing technical and tactical skills for soccer players,as well as in physical training programs,which results in training fields that cannot be relocated to the playing field and a disconnect between player training content and specific needs.Objective:This study was conducted from the perspective that the soccer player’s body is in a non-stable state when completing movements on the field of play,to investigate whether strength training in a non-stable state has an effect on the soccer player’s agility quality and whether there is a statistically significant difference between strength training in a non-stable state and strength training in a traditional stable interface on agility quality under the same training conditions,and to analyze the reasons for this difference.Methods:This study is an experimental study and uses literature,expert interviews,questionnaires,experimental methods,mathematical and statistical methods,and logical analysis.Among the many research methods,the experimental method was mainly used.20 male high school soccer players from Tongliao Experimental Middle School were divided into two groups,one experimental group(n=10)and the other control group(n=10),both of which underwent 12 weeks of training and twice weekly experimental intervention.Before the experimental intervention,the players in the experimental group and the control group were tested on the basic physical condition and the 5 agility indicators reflecting soccer players,and the data obtained were subjected to independent samples t-test using SPSS statistical software to ensure the homogeneity of the two groups.After the experimental intervention,five sensitivity quality test indexes were tested again to the two groups of players,and the effect of strength training in two different states on the sensitivity quality of high school male soccer players was compared by intra-group and inter-group comparative analysis,and the differences in impact effects.Results:After the 12-week experimental intervention,the following results were obtained from the comparison of data measured before and after the experiment within each group cohort:(1)There was a significant difference between the pre-test and post-test results of 20m dribbling over the bar in the experimental group(P<0.05),while there was no significant difference between the pre-test and post-test results of 20m dribbling over the bar in the control group(P>0.05).(2)There was a significant difference between the pre-test and post-test results of four-line round-trip running in the experimental group(P<0.05),and there was no significant difference between the pre-test and post-test results of four-line round-trip running in the control group(P>0.05).(3)The results of pre-test and post-test of T-run of the experimental group subjects were highly significant(P<0.01),and the results of pre-test and post-test of T-run of the control group subjects were not significantly different(P>0.05).(4)There was a highly significant difference between the pre-test and post-test results of V-running in the experimental group subjects(P<0.01),and there was no significant difference between the pre-test and post-test results of V-running in the control group subjects(P>0.05).(5)The results of pre-test and post-test of Illinois Run in the experimental subjects were highly significant(P<0.01),and the results of pre-test and post-test of Illinois Run in the control subjects were significantly different(P<0.05).Conclusion:Both unsteady-state strength training and steady-state strength training at 12 weeks after the experiment improved or improved the agility quality of high school male soccer players;compared with each other,unsteady-state strength training was superior in the improvement magnitude and effect of students’T-run,V-run,four round-trip runs and Illinois run,while both were the same in the improvement magnitude and effect of 20-meter dribbling over the pole.
