Study On The Relief Effect Of Tissue Flossing On Delayed Onset Muscle Soreness

Objective: In this study,we induced healthy college students to produce DOMS through exercise,and used fascia compression band as an intervention means to observe the changes of relevant indicators before and after exercise,and explore the relief effect of fascia compression zone on DOMS,in order to provide certain theoretical guidance for the recovery of soft tissue function of athletes and sports enthusiasts after exercise.Methods: 36 healthy male college students with irregular exercise habits were recruited as subjects and randomized into control group(CON),vibration intervention group(VIB)and fascia compression zone group(FLOSS),with 12 participants in each group.DOMS modeling of the dominant lateral quadriceps of the subject by the isokinetic muscle strength test training system,Serum creatine kinase concentrations were measured,analyzed at baseline,immediately,24 h,48h and 72 h after molding(Creatine Kinase,CK),deep fascia sliding ability(Deep fascia displacement,DF),Peak torque / Body weight(PT / BW)and Pressure pain threshold(PPT)(With CK,medial vastus muscle deep fascia displacement: VM-DF,musculus vastus lateralis deep fascia displacement: VL-DF,rectus femoris deep fascia displacement: RF-DF,isometric contraction Peak torque /Body weight: IS-PT / BW,concentric contraction Peak torque / Body weight: CC-PT /BW,eccentric contraction Peak torque / Body weight: EE-PT / BW,medial vastus muscle Pressure pain threshold: VM-PPT,musculus vastus lateralis Pressure pain threshold: VLPPT,rectus femoris Pressure pain threshold: RF-PPT),To explore the effect of the fascial compression zone on DOMS.Results:(1)CK concentration: the three groups showed to increase immediately after molding to 72 h after mold making,24 h and 72 h after mold making,the CON group was compared with VIB group and FLOSS group(p <0.05).(2)Fascia sliding ability:(1)VM-DF: 24 h,48h,72 h after mold making,CON group,VIB group,FLOSS group,and24 h and 72 h after mold making,VIB group and FLOSS group(p <0.05).(2)VL-DF: At24 h,48h and 72 h after mold making,there were significant differences between CON group and VIB group and FLOSS group,respectively(p <0.05).In VM-DF and VL-DF,they increased immediately after mock-forming,and suddenly decreased at 2 4 h after mock-forming(3)RF-DF: The interaction between intervention method and test time was not significant(p> 0.05).(3)Extension of knee muscle strength: the analysis of ISPT / BW and CC-PT / BW showed that the interaction between the intervention method and the test time was not significant(p> 0.05).EE-PT / BW: The three groups of EE-PT/ BW showed a trend of an immediate decline after molding,followed by a slow rise.At24 h,48h and 72 h after molding,CON and FLOSS differ significantly(p <0.05);at 48 h after molding,CON and VIB differ significantly(p <0.01).(4)Compression threshold:(1)VM-PPT,24 h,48h and 72 h after mold making,CON group and VIB group and FLOSS group respectively,72 h after mold making,VIB group and FLOSS group,all had significant differences(p <0.05).(2)VL-PPT,24 h and 48 h after mold making,CON group and VIB group,72 h after mold making,CON group and FLOSS group(p <0.01).VM-PPT and VL-PPT decreased by 24 h after mold molding.(3)RF-PPT,the interaction of intervention method and test time was not significant(p> 0.05).Conclusion:(1)After hard intensity eccentric contraction exercise,it can lead to the increase of serum CK concentration,weaken the sliding ability of the deep fascia,reduce the pressure pain threshold and reduce the muscle strength of the exercise site.(2)Tissue flossing and vibration training help to reduce the increase of CK concentration in athletes,which has the effect of promoting deep fascial sliding,relieving pain and restoring the eccentric contraction force,and the effect of tissue flossing is better than vibration training.(3)After exercise,the weakening of fascia sliding ability has a similar change trend with the reduction of pressure pain threshold,and the weakening of fascia sliding ability may be one of the reasons for DOMS.(4)Tissue flossing can effectively relieve DOMS by improving the sliding of the deep fascia at the compression site.
