Study On The Training Effect Of Functional Training Methods The Performance Of Pull-ups In The Sports Middle School Entrance Examination Items

Research purpose: To investigate the training effects of physical function training methods on secondary school students’ pull-up exercise performance through experimental methods,to explore positive and effective training methods for improving secondary school students’ upper limb strength,and to promote the continuous improvement of secondary school students’ physical fitness level.Research methods: The main methods used were literature,experimental method,interview method and questionnaire survey.Experimental research part: the experimental subjects were 40 male students in the first grade of a secondary school in Zhanjiang City,and the subjects were randomly divided into a physical function training intervention group(experimental group)and a conventional training intervention group(control group),with 20 subjects in each group.The average age,height and weight of the experimental group were 13.60 ± 0.59 years,161.60 ± 9.08 cm and 61.01 ± 12.23 kg respectively;the control group The mean age,height and weight of the control group were 13.70±0.47 years,164.15 ± 5.43 cm and 55.50 ± 10.49 kg respectively.the physical function training intervention was divided into two phases,the first phase(week one to four)used prone T’s,elastic rope rowing,plank support,dumbbell single arm rowing and centrifugal pulling as the intervention tools,the second phase(week five to eight)Students were trained using interventions including advanced movements such as abdominal disc oblique pull-ups,suspension band prone pulls,suspension band prone tucks,and abdominal disc prone YW’s.Each intervention was scheduled during the warm-up portion of the students’ PE class(approximately twenty minutes)and the intervention was conducted twice a week for a total of eight weeks.Flexed arm dips,forward grip pull-ups,solid ball tosses and reverse grip pull-ups were used as the four tests in this experiment.After the eight-week intervention,SPSS software was used to test the scores of the control and experimental groups.A paired samples t-test was used to compare the pre and post test scores within the group,and an independent samples t-test was used to compare the scores between groups.Results: Compared with the pre-intervention period,the mean score of the positive grip pull-up index in the experimental group at the end of the experiment was4.1±4.051,an increase of 1±0.759 compared with the pre-intervention period(3.1±3.698),with a significant difference(p<0.05)and an increase of 32.2%.In the control group,the mean score of forward grip pull-up index after intervention was 2.65±3.731,which was 0.4±0.502 higher than that before intervention(2.25±3.782),with a significant difference(p<0.05)and an improvement of 17.7%.In the reverse grip pull-up index,the mean score of the experimental group after intervention was 3.90±3.640,which was higher than that before intervention(The mean score of the experimental group was 3.90±3.640 pull-ups,which was 0.85±0.131 higher than that of the pre-intervention group(3.05±3.364),with a significant difference(p<0.05)and an increase of 27.8%.The mean score of the control group after the intervention was 3.25±3.242,which was 0.50±0.606 higher than that before the intervention(2.75±3.274),with a significant difference(p<0.05)and an improvement of 16.07%;in the index of flexion-arm dip,the mean score of the experimental group after the intervention was 19.815±12.436 s,compared with that before the intervention(The mean performance of the experimental group was 19.815±12.436 s,which was 8.715±1.252 s higher than that of the pre-intervention group(11.093±12.655s),with a significant difference(p<0.05)and an improvement of 78.62%.The mean score of the control group after the intervention was 12.395±9.701 s,an improvement of 0.73±0.456 s compared with that before the intervention(11.608 ± 9.460s),a significant difference(p<0.05)of 6.77%.The mean score of the experimental group was 7.595±1.162 m,which was 0.98 ± 0.347 m higher than that of the pre-intervention group(6.615 ± 1.289m),with a significant difference(p<0.05)and an improvement of14.81%.The mean score of the control group after the intervention was 6.565 ±1.596 m,which was 0.24±0.131 m higher than that before the intervention(6.325±1.607m),with a significant difference(p<0.05)and an improvement of 3.79%.After the intervention,the mean score in the positive grip pull-up index was 4.1±4.051 for the experimental group and 2.65±3.731 for the control group,with no significant difference(p>0.05).The mean improvement in the experimental group was 1.45± 0.759 compared to 0.4± 0.502 in the control group,with a significant difference(p<0.05);in the reverse grip pull-up index,the mean score of the experimental group after the intervention was 3.90±3.640 compared to 3.25±3.242 in the control group,with no significant difference(p>0.05).The mean improvement in performance was 0.85±0.131 for the experimental group and 0.50±0.606 for the control group,which was not significantly different(p>0.05).The mean improvement of the experimental group was 8.715±1.252 s,compared to 0.73±0.456 in the control group,with a significant difference(p<0.05).In the solid ball throwing index,the mean performance of the experimental group was 7.565±1.142 m,compared to 6.565± 1.596 m in the control group,with a significant difference(p<0.05).The mean improvement in performance was 0.98±0.347 m in the experimental group and 0.24±0.131 m in the control group,with a significant difference(p<0.05).Conclusion: The physical function training method has a better training effect on pull-up performance than the conventional training method.The physical function training method was the most effective in improving the performance of the flexed arm drape exercise,followed by the forward grip pull-up,reverse grip pull-up and finally the solid ball throw.
