<![CDATA[Penelitian ini menganalisis hubungan daya ledak otot tungkai dan daya tahan otot perut, baik secara parsial maupun simultan, dengan performa lari 100 meter mahasiswa Program Studi Pendidikan Jasmani, Kesehatan, dan Rekreasi tahun 2026. Mario FebrianDaya ledak tungkai diukur menggunakan standing broad jump, daya tahan otot perut menggunakan sit-up 30 detik, dan performa sprint menggunakan tes lari 100 meter. Data dianalisis dengan statistik deskriptif, uji normalitas Liliefors, korelasi product moment, korelasi ganda, uji t, dan uji F pada taraf signifikansi 0,05. Rata-rata standing broad jump adalah 2,31±0,314 m, sit-up 17,57±6,461 repetisi, dan waktu 100 meter 14,61±1,563 detik. Analisis sumber melaporkan hubungan sangat kuat antara daya ledak tungkai dan performa sprint (r=0,996; t=48,59) serta antara daya tahan otot perut dan performa sprint (r=0,977; t=19,99); hubungan simultan juga dilaporkan sangat kuat (R=0,991). Temuan mendukung penggunaan tes power tungkai dan endurance trunk sebagai indikator pendukung evaluasi sprint. Namun, desain korelasional, sampel kecil, komposisi jenis kelamin yang tidak seimbang, dan penggunaan stopwatch membatasi inferensi kausal serta generalisasi hasil. This study examined the partial and simultaneous relationships of lower-limb explosive power and abdominal muscular endurance with 100-m sprint performance among students in the Physical Education, Health, and Recreation Study Program in 2026. A quantitative correlational design was applied to 21 students with complete data drawn from a population of 141 students enrolled in a basic athletics course. Lower-limb explosive power was assessed using the standing broad jump, abdominal muscular endurance using a 30-s sit-up test, and sprint performance using a 100-m running test. Data were analyzed using descriptive statistics, the Liliefors normality test, Pearson product-moment correlation, multiple correlation, t tests, and an F test at a significance level of 0.05. Mean performances were 2.31±0.314 m for the standing broad jump, 17.57±6.461 repetitions for sit-ups, and 14.61±1.563 s for the 100-m sprint. The source analysis reported very strong relationships between lower-limb explosive power and sprint performance (r=0.996; t=48.59) and between abdominal muscular endurance and sprint performance (r=0.977; t=19.99); the simultaneous relationship was also reported as very strong (R=0.991). These findings support the use of lower-limb power and trunk-endurance tests as complementary indicators in sprint assessment. Nevertheless, the correlational design, small sample, unbalanced sex composition, and stopwatch timing limit causal inference and generalizability.]]>
