Abstract:
Objective:To explore the activation characteristics and synergistic mode of lumbar and abdominal core muscle group during abdominal breathing training.Method:Thirty-two healthy college students were recruited and randomly divided into the control group and the experimental group with 16 cases in each group.The control group received stan-pile training,while the experimental group received abdominal breathing and stan-pile training 5 times a week for 8 weeks.The sur-face electromyography of the lumbar and abdominal core muscles was collected before and after the interven-tion.Non-negative matrix factorization(NMF)was used to extract extract muscle synergy patterns from the EMG data.Result:In terms of cooperative elements,the number of cooperative elements increased after intervention in both groups compared with baseline,but there was no significant difference in the number of cooperative ele-ments between the two groups before intervention(P>0.05),and there was a significant difference in the num-ber of cooperative elements after intervention(P<0.05).In terms of cooperative patterns,the cooperative pat-terns before intervention in the two groups were similar.After intervention,the cooperative patterns in the two groups were different,the control group showed coactivation of the right transversus abdominis,left internal oblique,right erector spinae,and bilateral multifidus throughout the breathing cycle.In contrast,the experimen-tal group exhibited pronounced activation of bilateral erector spinae and multifidus during inhalation,and bilater-al transversus abdominis,left external oblique,and left erector spinae during exhalation.The activation curves before intervention in the two groups were similar,and the activation curves after intervention in the two groups trended towards slowing down,with the time feature of the activation curve in the experimental group being more obvious.Conclusion:Abdominal breathing training can increase the number of cooperative tuples of the waist and abdo-men muscles,and the muscles perform efficient division of labor after training to form an adaptive coopera-tive mode.
