The Interaction In Performance Between Core Muscle And Respiratory Muscle

To identify the interaction in performance between core muscle (CM) and respiratorymuscle (RM), identical function tests of both RM and CM were repeatedly examined,whenever the performance of either RM or CM has been improved or decreased by training orschemes.Twenty-four amateur long-distance runners were recruited and separated into threegroups randomly: training group (TRA,7males and1female) first took part in a4-weekinspiratory muscle training (IMT) protocol and then a six-week interval training on treadmillwith special core training (ITCT) protocol; control group(CON,6males and1female) was notgiven any specialized training or schemes; scheme group(SCH,9males) was given twoschemes, of which can either make respiratory muscle(Mimic Respiration scheme) or coremuscle (Fatigue Core Muscle Workout scheme) fatigue separately. They performed ModifiedPlank Test (MPT) and MIP (maximum inspiratory press) Test before and after eachtraining/scheme respectively to measure the changes in performance of CM and RM.Both MIP (p<0.001) and the performance in MPT (p<0.05) increased in TRA after IMTcompare with control value and the effect within and between group were significant (p<0.05)in MIP, and so did the effect between group in MPT (p<0.05). MIP and PMPT reduced afterMimic Respiration (MR) scheme in SCH (p<0.05). The subjects in TRA performed better inMPT after ITCT (p<0.05), but not significantly in MIP (p>0.05). MIP and PMPT in SCHreduced significantly (p<0.001) after Fatigue Core Muscle Workout (FCMW) scheme. Inaddition, for the changes in MIP and PMPT, negative correlation was found betweenthem(r<0.03, p>0.05). However, the extent of changes in MIP and PMPT exited moderatecorrelation (r=0.663), but not significantly (p=0.337).Such findings suggested that the interaction in performance between RM and CM mayexist.
