Purpose: This study aimed to investigate the changes in the muscle activity of the trunk stabilizer muscles before and after incorporating Pilates breathing during three types of Pilates chair exercises. Methods: This study included 33 healthy men and women in their 20's; they were recruited according to the inclusion and exclusion criteria. sEMG was used to measure the changes in the muscle activity in the internal oblique/transverse abdominis, rectus abdominis, and erector spinae during the three types of Pilates chair movements (footwork, twist footwork, and bridging) without and with the Pilates breathing integration. The muscle activities of the trunk stabilizers between without and with Pilates breathing were statistically analyzed and compared. Results: The internal oblique/transverse abdominis showed an increase and a significant difference in the muscle activity in all three movements of footwork, twist footwork, and bridging after the Pilates breathing integration (p<.001). The muscle activity of the rectus abdominis (p<.05) and the erector spinae (p<.05) also increased and showed a significant difference after the Pilates breathing incorporation, except in the bridging movement for the erector spinae. The increase in the rate after integrating Pilates breathing was relatively greater in internal oblique/transverse abdominis than in other muscles. Conclusion: When Pilates breathing was applied, the activities of the trunk stabilizer muscles increased significantly and immediately in all three movements of Pilates chair footwork, twist footwork, and bridging. This means that the use of breathing is expected to have a positive and immediate effect on the activation of trunk stabilizers, thus indicating that it can possibly be an effective re-enforcing tool to promote trunk stability when it is integrated to the Pilates chair exercise. Incorporating Pilates breathing also seemed to have a tendency to activate the deep trunk stabilizer muscles more than the superficial stabilizer muscles.

Purpose: The purpose of this study was to assess the effects of breathing techniques on trunk muscle activity and balance during Pilates reformer footwork exercises, comparing results both within and between groups before and after the intervention. Methods: Thirty-one adult women over the age of 20 were selected as subjects for this study. They were divided into a Pilates breathing group (n = 15) and a general breathing group (n = 16) using a randomized control group study design. A surface electromyogram was used to measure muscle activity within and between the groups before and after the reformer footwork exercise. Static balance measurements were taken while standing on two legs, and dynamic balance measurements were taken while standing on one leg. All measurements were taken three times, and the average values were used for analysis. Results: The results of the study showed that muscle activity increased with significant differences in the external oblique and transverse abdominal muscles after exercise in the pre-post comparison within the Pilates breathing group (p < 0.05). In the between-group comparison, there was a significant difference in the increase in muscle activity of the external oblique and transverse abdominal muscles in the Pilates breathing group (p < 0.05). In the pre-post comparison of static and dynamic balance within the Pilates breathing group, there was a significant increase (p < 0.05) after exercise. The Pilates breathing group also showed a significant increase even in the between-group comparison (p < 0.05). Conclusion: This study confirmed that reformer footwork exercise accompanied by Pilates breathing has positive effects on muscle activity and static balance ability of trunk muscles in adult women. Therefore, reformer footwork exercise accompanied by Pilates breathing can be presented as an effective exercise method to increase trunk stability and balance ability through the simultaneous activity of the trunk muscles.

본 연구는 배드민턴 전위와 후위에서 스트로크 이후 제2동작의 움직임에 대한 피드백을 제공함으로서 훈련의 효율성을 제고시키고자 하였다. 본 연구를 통해 다음과 같은 결론을 얻었다. 스매시의 경우 타점을 높일 수 있도록 Impact 타임을 조절해야한다. S1의 스매시는 스텝 스매시로 가장 빠른 라켓헤드의 속도를 보여 임팩트 시 강하고 효율적인 힘의 전달을 하고 있는 것으로 나타났으며, 스트로크 구사 시 Impact 시 라켓속도와 Max속도가 유사해 Impact 타임이 가장 좋은 것으로 나타났다. 1step 시 S5를 제외한 모든 선수들 착지 시 전방에 있는 오른발로 1step을 하는 것으로 홉 스텝을 이용한 첫 스텝이 이루어진 것으로 나타났다. 스트로크 시 최적의 스윙을 만들기 위해서는 팔꿈치 관절이나 손목관절의 협응 동작에 필요한 최적의 조건을 만들어 주는 것이 중요하다. 라켓의 회전반경은 크고 셔틀콕의 선속도도 빠르게 해야 한다. 스텝은 양 발의 조직적인 움직임으로 좌우 밸런스가 중요하다. 실제 경기에 있어서 step은 대부분이 2-4보 정도의 스텝으로 이루어져야하며, 상황에 따라 적절한 step 구사와 민첩성, 순발력 강화 훈련 프로그램 등이 요구된다.
