Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh daya tahan otot core dan fleksibilitas Lumbo pelvic terhadap perubahan sagittal alignment tulang belakang pada remaja Pondok Pesantren Darul Hufadz. Penelitian menggunakan metode kuantitatif dengan pendekatan kausalitas. Sampel penelitian berjumlah 30 remaja yang dipilih menggunakan teknik total sampling. Daya tahan otot core diukur menggunakan Full Plank Test, fleksibilitas Lumbo pelvic menggunakan Sit and Reach Test, sedangkan sagittal alignment diukur menggunakan Flexicurve. Analisis data dilakukan menggunakan regresi linear berganda dengan bantuan SPSS versi 27.0. Hasil penelitian menunjukkan bahwa secara parsial daya tahan otot core tidak berpengaruh signifikan terhadap perubahan sagittal alignment (Sig. = 0,857 > 0,05), sedangkan fleksibilitas Lumbo pelvic berpengaruh signifikan (Sig. = 0,009 < 0,05). Secara simultan, daya tahan otot core dan fleksibilitas Lumbo pelvic berpengaruh signifikan terhadap perubahan sagittal alignment tulang belakang (Sig. = 0,029 < 0,05) dengan nilai R² = 0,231, yang berarti kedua variabel menjelaskan 23,1% variasi perubahan sagittal alignment. Kata kunci: daya tahan otot core, fleksibilitas Lumbo pelvic, sagittal alignment, remaja, pondok pesantren. ***** This study aimed to determine the effect of core muscle endurance and lumbopelvic flexibility on changes in sagittal spinal alignment among adolescents at Darul Hufadz Islamic Boarding School. This research employed a quantitative method with a causal approach. The study involved 30 adolescents selected using the total sampling technique. Core muscle endurance was measured using the Full Plank Test, lumbopelvic flexibility was assessed using the Sit and Reach Test, and sagittal spinal alignment was measured using the Flexicurve. Data were analyzed using multiple linear regression with SPSS version 27.0. The results showed that, partially, core muscle endurance had no significant effect on sagittal spinal alignment (Sig. = 0.857 > 0.05), whereas lumbopelvic flexibility had a significant effect (Sig. = 0.009 < 0.05). Simultaneously, core muscle endurance and lumbopelvic flexibility had a significant effect on changes in sagittal spinal alignment (Sig. = 0.029 < 0.05), with an R² value of 0.231, indicating that both independent variables explained 23.1% of the variance in sagittal spinal alignment. Keywords: core muscle endurance, lumbopelvic flexibility, sagittal spinal alignment, adolescents, Islamic boarding school.
