Abstract

Penelitian ini bertujuan untuk : 1) mengetahui hubungan fleksibilitas ankle dengan kecepatan finswimming nomor 50 meter bifins. 2) mengetahui hubungan daya ledak otot tungkai dengan kecepatan finswimming nomor 50 meter bifins. 3) mengetahui hubungan fleksibilitas ankle dan daya ledak otot tungkai secara bersama sama dengan kecepatan finswimming nomor 50 meter bifins. Penelitian ini menggunakan pendekatan kuantitatif dengan metode deskriptif korelasional. Populasi penelitian adalah seluruh Club Milakancana Dive Center sebanyak 31 atlet. Sampel penelitian berjumlah 31 atlet Club Milakancana Dive Center yang ditentukan menggunakan teknik total sampling atau sensus sampling. Instrumen tes pada penelitian ini adalah : 1) Fleksibilitas Ankle, untuk mengukur ruang gerak pada ankle. 2) Vertical jump untuk mengukur daya ledak otot tungkai. 3) Sprint 50 meter bifins untuk mengetahui hasil kecepatan 50 meter bifins. Data dianalisis menggunakan statistik deskriptif, korelasi Product Moment, korelasi ganda, uji t, dan uji F. Hasil penelitian menunjukkan bahwa 1) terdapat hubungan antara fleksibilitas ankle dengan kecepatan finswimming 50 meter bifins (r = 0,67) dimana hal ini ditunjukkan dengan thitung = 4,86 > ttabel = 2,045, dengan persamaan regresi yaitu (Ŷ = 16,51 + 0,67 X₁) dimana kenaikan variabel X₁ sebesar 0,67 diikuti pula oleh variabel Y sebesar 16,51. 2) terdapat hubungan antara daya ledak otot tungkai dengan kecepatan finswimming 50 meter bifins (r = 0,80) dimana hal ini ditunjukkan dengan thitung = 7,16 > ttabel = 2,045, dengan persamaan regresi yaitu (Ŷ = 10,03 + 0,80 X₂) dimana kenaikan variabel X₂ sebesar 0,80 diikuti pula oleh variabel Y sebesar 10,03. 3) terdapat hubungan antara fleksibilitas ankle dan daya ledak otot tungkai secara bersama-sama dengan kecepatan finswimming 50 meter bifins (R = 0,86) dimana hal ini ditunjukkan dengan Fhitung = 38,74 > Ftabel = 3,34, dengan persamaan regesi yaitu (Ŷ = 1,15 + 0,36 X₁ + 0,62 X₂) dimana variabel X₂ memiliki hubungan yang lebih kuat terhadap Y dibandingkan dengan variabel X₁, karena nilai koefisien X₂ (0,62) lebih tinggi daripada koefisien X₁ (0,36). Hasil uji hipotesis menunjukkan bahwa H₀ ditolak dan H₁ diterima pada ketiga hipotesis penelitian. Dengan demikian, fleksibilitas ankle dan daya ledak otot tungkai memiliki hubungan dengan kecepatan finswimming nomor 50 meter bifins pada atlet Milakancana Dive Center. ***** This study aims to: 1) determine the relationship between ankle flexibility and finswimming speed in the 50-meter bifins event. 2) determine the relationship between leg muscle explosive power and finswimming speed in the 50-meter bifins event. 3) determine the relationship between ankle flexibility and leg muscle explosive power together with finswimming speed in the 50-meter bifins event. This study uses a quantitative approach with a descriptive correlational method. The study population was all 31 athletes of the Milakancana Dive Center Club. The study sample consisted of 31 athletes of the Milakancana Dive Center Club who were determined using total sampling or census sampling techniques. The test instruments in this study were: 1) Ankle Flexibility, to measure the range of motion in the ankle. 2) Vertical jump to measure leg muscle explosive power. 3) 50-meter bifins sprint to determine the results of the 50-meter bifins speed. The data were analyzed using descriptive statistics, Product Moment correlation, multiple correlation, t-test, and F-test. The results of the study showed that 1) there is a relationship between ankle flexibility and the speed of 50-meter bifins finswimming (r = 0.67) where this is indicated by tcount = 4.86 > ttable = 2.045, with a regression equation of (Ŷ = 16.51 + 0.67 X₁) where the increase in the X₁ variable of 0.67 is also followed by the Y variable of 16.51. 2) there is a relationship between the explosive power of the leg muscles and the speed of 50-meter bifins finswimming (r = 0.80) where this is indicated by tcount = 7.16 > ttable = 2.045, with a regression equation of (Ŷ = 10.03 + 0.80 X₂) where the increase in the X₂ variable of 0.80 is also followed by the Y variable of 10.03. 3) There is a relationship between ankle flexibility and leg muscle explosive power together with the speed of 50-meter finswimming with fins (R = 0.86) as indicated by Fcount = 38.74 > Ftable = 3.34, with the regression equation being (Ŷ = 1.15 + 0.36 X₁ + 0.62 X₂) where variable X₂ has a stronger relationship to Y compared to variable X₁, because the coefficient value of X₂ (0.62) is higher than the coefficient of X₁ (0.36). The results of the hypothesis test indicate that H₀ is rejected and H₁ is accepted for all three research hypotheses. Thus, ankle flexibility and leg muscle explosive power are related to the speed of 50-meter finswimming with finswimming with finswimming in Milakancana Dive Center athletes.
