Abstract

*****ABSTRAK**** Penelitian ini bertujuan untuk mengetahui pengaruh kekuatan otot tungkai dan fleksibilitas terhadap lari cepat 60 meter pada atlet disabilitas intelektual ringan. Sampel penelitian adalah atlet disabiltas intelektual ringan berjumlah 35 atlet, Pendekatan penelitian yang digunakan dalam penelitian ini adalah asosiatif multivatiat, dengan metode survei dan teknik tes parameter. Teknik analisis menggunakan pendekatan analisis jalur (path analysis) pada taraf signifikansi senilai 0,05. Secara umum, hasil penelitian berdasarkan hasil pengujian analisis jalur terhadap setiap hipotesis didapat P-value < taraf signifikansi 0,05 yang berarti bahwa setiap hipotesis penelitian (H1) dan (H2) diterima. setiap peningkatan kekuatan otot tungkai akan mengurangi waktu sebesar 0,042,sedangkan peningkatan fleksibilitas akan mengurangi waktu sebesar 0,135. Kedua variabel berpengaruh signifikan (0,001<0,05) artinya H1 diterima atau variabel Kekuatan Otot Tungkai berpengaruh signifikan terhadap Lari Cepat 60 Meter,artinya H2 diterima atau variabel Fleksibilitas berpengaruh signifikan terhadap Lari Cepat 60 Meter. Kata Kunci: Kekuatan Otot Tungkai, Flexibilitas, Lari Cepat 60 Meter, Disabilitas intelektual ringan *****ABSTRACT**** This study aims to examine the influence of leg muscle strength and flexibility on 60-meter sprint performance among athletes with mild intellectual disabilities. The research sample consisted of 35 athletes with mild intellectual disabilities. The study employed a multivariate associative approach using survey methods and parametric testing techniques. Data analysis was conducted through path analysis with a significance level of 0.05. The results demonstrated that all research hypotheses (H1) and (H2) were accepted, as indicated by p-values < 0.05. Specifically, every unit increase in leg muscle strength reduced sprint time by 0.042 seconds, while each unit increase in flexibility decreased time by 0.135 seconds. Both variables showed statistically significant effects (0.001 < 0.05), confirming that: (1) H1 was accepted - leg muscle strength significantly affects 60-meter sprint performance, and (2) H2 was accepted - flexibility significantly influences 60-meter sprint performance. Keywords: Leg Muscle Strength, Flexibility, 60-Meter Sprint, Intellectual Disability
