| Bilateral transfer is a part of skill transfer in sports,which refers to an individual’s ability to use the same skill learned on one side of the body to perform or learn the skill on the other side of the body.Strengthening the weaker side of the body is essential in sports such as badminton,which involve asymmetrical movements.With the vigorous development of sports skills and the continuous enrichment and popularization of badminton teaching and training methods,the high-intensity competition places stricter demands on athletes’ comprehensive skills,highlighting the importance of backhand high-altitude skills in badminton.Related studies have shown that bilateral transfer of skills exists not only in asymmetric sports such as basketball and football,but also in sports such as javelin,shot put,and table tennis that rely on unilateral movements.Therefore,in badminton,can training the weaker side of the body in the same way as the dominant side produce contralateral transfer to promote the improvement of backhand high-altitude skills?This study selected 40 male students with a badminton foundation and a right-handed dominance as the experimental subjects(20 in the experimental group and 20 in the control group).The backhand high-altitude skill in badminton was chosen as the teaching content.In the experimental group,the weaker side of the body was trained first before using the dominant side for training.In the control group,only the dominant side was trained.The difference in the level of backhand high-altitude skill on the dominant side between the experimental group and the control group was observed before and after the experiment,and the impact of bilateral transfer theory on backhand high-altitude skill in badminton was explored.The study concluded that:(1)There were significant differences(p<0.05)in FMS,left-hand grip strength,and left/right-hand ball control before and after the experiment in the experimental group of 20 male students who had a badminton foundation and were right-handed(20 people in the control group).The experimental group first trained the weaker side of the body and then trained with the dominant side of the body,while the control group only trained with the dominant side of the body.The difference in the level of backhand high-altitude skills between the dominant sides of the experimental and control groups before and after the experiment was observed to explore the impact of bilateral transfer theory on backhand high-altitude skills in badminton.There were no significant differences(p>0.05)in right-hand grip strength,standing long jump,and double-foot skipping before and after the experiment in both groups.FMS,left/right-hand grip strength,right-hand ball control,standing long jump,and skipping did not show significant differences(p>0.05)after the experiment in both groups,indicating that strengthening the weaker side of the body had a positive effect on the coordination ability of both sides of the body,and improving the learning of left-hand technique can enhance the player’s ball sense,thereby better promoting the learning of badminton technique,but has little effect on strength and other qualities.(2)There were significant differences(p<0.05)in the accuracy of left and right backhand high-altitude shuttlecock landing points before and after the experiment in the experimental group,while in the control group,there was a significant difference(p<0.05)in the accuracy of the right backhand high-altitude shuttlecock landing point before and after the experiment,but no significant difference(p>0.05)in the accuracy of the left backhand high-altitude shuttlecock landing point.After the experiment,there were significant differences(p<0.05)between the experimental and control groups in the accuracy of left and right backhand high-altitude shuttlecock landing points.These findings suggest that both strengthening the training of the weaker side of the body and continuously reinforcing the training of the dominant side of the body are effective ways to improve backhand high-altitude shuttlecock skills,and that strengthening the training of the weaker side of the body has a greater effect on improving the skill level of the dominant side of the body than simply using the dominant side of the body for training.(3)There were significant differences in the motion technique scores of the experimental group’s left and right backhand clears before and after the experiment(p<0.05),indicating that practicing with the weaker limb deepened participants’ understanding of the backhand clear technique and had a significant effect on the technique score.For the control group,there were significant differences in the motion technique scores of the right backhand clear before and after the experiment(p<0.05),while the scores for the left backhand clear did not have significant differences(p>0.05),validating that traditional teaching methods can also regulate motion technique.After the experiment,there was no significant difference in the motion technique score of the right backhand clear between the experimental and control groups(p>0.05),while there was a significant difference in the score of the left backhand clear(p<0.05),indicating that the bilateral transfer theory applied to badminton backhand clear teaching,and that strengthening non-dominant limb technique practice was not significantly different from pure dominant limb training in terms of improving motion regularity.(4)There exists bilateral transfer phenomenon in the training of badminton backhand high clear.Combined with research findings from other papers,bilateral transfer phenomenon also exists in the learning process of badminton forehand high clear,forehand drop shot,backhand high clear and other techniques.Using the theory of bilateral transfer to enhance the training of the non-dominant side of the body to improve the level of related badminton techniques in the training object is a feasible method.The purpose of this study is to explore the effect of training the non-dominant limb in the backhand clear technique of badminton on the dominant limb’s performance,and provide a theoretical basis for the application of bilateral transfer in badminton.It is suggested that in future research and teaching,(1)a deeper understanding and learning of the theory of bilateral transfer is necessary,(2)the application of bilateral transfer theory in badminton training should be strengthened,(3)the timing of bilateral transfer training should be carefully selected. |
