Pengaruh Dynamic Core Stability Exercise dan Squat Jump terhadap Keseimbangan Dinamis pada Atlet Bulu Tangkis Suryabaja Surabaya

Latar Belakang: Keseimbangan dinamis merupakan salah satu komponen penting dalam olahraga bulu tangkis karena berperan dalam menjaga stabilitas tubuh saat melakukan gerakan cepat, perubahan arah, lompatan, dan pendaratan. Keseimbangan dinamis yang kurang baik dapat meningkatkan risiko cedera serta menurunkan performa atlet. Dynamic Core Stability Exercise dan Squat Jump merupakan bentuk latihan yang dapat meningkatkan kekuatan otot inti, kekuatan otot tungkai, koordinasi neuromuskular, serta propriosepsi yang berperan dalam peningkatan keseimbangan dinamis. Penelitian ini bertujuan untuk mengetahui pengaruh Dynamic Core Stability Exercise dan Squat Jump terhadap keseimbangan dinamis pada atlet bulu tangkis Suryabaja Surabaya. Metode Penelitian: Penelitian ini menggunakan desain pre-experimental dengan pendekatan one group pretest-posttest design. Sampel penelitian berjumlah 10 atlet bulu tangkis usia 7–12 tahun yang dipilih menggunakan teknik purposive sampling. Intervensi berupa Dynamic Core Stability Exercise (mountain climber dan plank hip dips) serta Squat Jump diberikan selama 6 minggu dengan frekuensi 3 kali per minggu. Pengukuran keseimbangan dinamis dilakukan menggunakan Star Excursion Balance Test (SEBT) sebelum dan sesudah intervensi. Analisis data menggunakan uji Shapiro-Wilk untuk uji normalitas dan Paired Sample T-Test untuk uji hipotesis. Hasil: Hasil yang didapatkan dari penelitian tersebut bahwa pemberian Dynamic Core Stability Exercise dan Squat Jump secara signifikan dapat meningkatkan keseimbangan dinamis (p<0,05). Kesimpulan: Dapat disimpulkan bahwa pemberian Dynamic Core Stability Exercise dan Squat Jump selama 6 minggu berpengaruh signifikan terhadap peningkatan keseimbangan dinamis pada atlet bulu tangkis usia 7–12 tahun di Club Suryabaja Surabaya.

Background: Dynamic balance is an important component in badminton because it plays a role in maintaining body stability during rapid movements, changes in direction, jumps, and landings. Poor dynamic balance can increase the risk of injury and reduce athlete performance. Dynamic Core Stability Exercise and Squat Jump are forms of exercise that can improve core muscle strength, leg muscle strength, neuromuscular coordination, and proprioception, which play a role in improving dynamic balance. This study aims to determine the effect of Dynamic Core Stability Exercise and Squat Jump on dynamic balance in badminton athletes from Suryabaja Surabaya. Research Methods: This study used a pre-experimental design with a one-group pretest-posttest design approach. The research sample consisted of 10 badminton athletes aged 7–12 years who were selected using a purposive sampling technique. The intervention in the form of Dynamic Core Stability Exercise (mountain climber and plank hip dips) and Squat Jump was given for 6 weeks with a frequency of 3 times per week. Dynamic balance measurements were carried out using the Star Excursion Balance Test (SEBT) before and after the intervention. Data analysis used the Shapiro-Wilk test for normality and the Paired Sample T-Test for hypothesis testing. Results: The results obtained from this study showed that the provision of Dynamic Core Stability Exercise and Squat Jump can significantly improve dynamic balance (p<0.05). Conclusion: It can be concluded that the provision of Dynamic Core Stability Exercise and Squat Jump for 6 weeks has a significant effect on improving dynamic balance in badminton athletes aged 7–12 years at the Suryabaja Club, Surabaya.
