Abstract
This study is an experimental study that uses the Abdominal Draw-In Maneuver (ADIM) and Abdominal Bracing Maneuver (ABM) to determine the effects of leg muscle-building exercises. The experiment was conducted on 40 normal people in their 20s who had no special problems or pain in the musculoskeletal and nervous systems. Muscle activities of lower extremity, including rectus femoris (RF), biceps femoris (BF), tibialis anterior (TA), and gastrocnemius, were measured during lunge exercise with ADIM and ABM. The study found that the muscle activity of TA was significantly higher during lunge exercise with ADIM compared to the baseline, with an average of 377.025 ㎶, and an average of 262.022 ㎶, respectively. However, the muscle activities of RF, BF, and gastrocnemius was not significant in the application of general lunge, ADIM, and ABM. The results of this study suggest that lunge exercise with the ADIM can be used to improve TA. Further studeis require the involvement of patients with weakened leg muscles in order to warrant the results of this study.
