Purpose : The aim of this study was to compare the effects of the abdominal draw-in exercise (ADIE) and the dead bug exercise (DBE) on the pelvic anterior tilt angle (PATA) and the activities of the gluteus maximus (GM), erector spinae (ES), and semi-tendinosus (ST) during prone hip extension (PHE).
Methods : A total of 22 female adults with weak abdominal muscles were divided into two groups: ADIE group (n=11) and DBE group (n=12). Before the intervention, PATA and the activities of GM, ES, and ST during PHE were measured. Subsequently, two groups conducted the assigned exercise for 10 minutes, and their muscle activities and the pelvic angle were re-measured after the exercise.
Results : In the DBE group, the muscle activity of GM was significantly increased after the intervention (p<0.05). Moreover, in both groups, the activity of ES and the PATA decreased significantly after the intervention (p<0.05). For all other variables, there was no significant difference in the changes before and after intervention between the two groups (p>0.05).
Conclusion : Therefore, we suggest that ADIE and DBE are effective for women with weak abdominal muscles since the ES activity and PATA are reduced during PHE.
