Performa smash pada bola voli dipengaruhi oleh pemanfaatan stretch–shortening cycle (SSC) dan kekuatan–koordinasi bahu (rotasi internal). Studi ini membandingkan knee tuck jump (KTJ) sebagai pliometrik berbasis SSC dan latihan karet elastik yang menarget power lengan terhadap peningkatan kemampuan smash atlet voli putri remaja. Desain dua-kelompok pretest–posttest selama 6 minggu (±18 sesi; n=12, masing-masing kelompok n=6). Outcome utama adalah skor smash terstandar (5 percobaan; total 0–25). Analisis fokus pada perubahan dalam-kelompok (uji paired t) dan perbandingan antar-kelompok pada ?skor (uji independent t), disertai ukuran efek. Hasil: Kelompok KTJ meningkat dari 8,00 ± 4,38 menjadi 10,67 ± 0,82 (?mean = +2,67; p = 0,221; d? ? 0,57). Kelompok karet meningkat dari 6,17 ± 2,14 menjadi 10,00 ± 3,03 (?mean = +3,83; p = 0,028; d? ? 1,25). Perbandingan antar-kelompok pada ?skor tidak signifikan (p = 0,614; Hedges’ g ? 0,27). Kedua intervensi meningkatkan skor smash; latihan karet efektif dalam-kelompok, tetapi belum terbukti lebih unggul dari KTJ pada desain dan ukuran sampel ini. Program dapat mengombinasikan KTJ (stimulasi SSC/kesiapan loncat) dan karet (kontrol skapulo-humeral/rotasi internal) dengan penekanan pada kualitas repetisi dan kepatuhan. Keterbatasan meliputi ukuran sampel kecil, potensi ketimpangan baseline, variasi kehadiran/kelelahan, dan variabilitas toss; riset lanjutan disarankan dengan sampel lebih besar dan analisis berbasis ANCOVA/model campuran.
Effectiveness of Knee Tuck Jump and Elastic-Band Training on Spike Performance in Adolescent Female Volleyball Players
Abstract
Volleyball spike performance hinges on effective stretch–shortening cycle (SSC) use and shoulder internal-rotation strength–coordination. This study compared knee tuck jump (KTJ)—a plyometric SSC stimulus—and elastic-band training targeting upper-limb power on adolescent female players’ spike performance. A two-group pretest–posttest design over 6 weeks (?18 supervised sessions; n=12; 6 per group). The primary outcome was a standardized spike score (five trials; total 0–25). Analyses emphasized within-group change (paired t) and between-group comparison on ?scores (independent t), with effect sizes. Results: KTJ improved from 8.00 ± 4.38 to 10.67 ± 0.82 (?mean = +2.67; p = 0.221; Cohen’s d? ? 0.57). Elastic-band improved from 6.17 ± 2.14 to 10.00 ± 3.03 (?mean = +3.83; p = 0.028; Cohen’s d? ? 1.25). The between-group difference on ?scores was non-significant (p = 0.614; Hedges’ g ? 0.27). Both interventions increased spike scores; elastic-band training was effective within-group, yet not superior to KTJ given this design and sample size. Coaches may combine KTJ (SSC/jump readiness) with elastic bands (scapulohumeral control/internal rotation), emphasizing repetition quality and adherence. Limitations include small sample size, possible baseline imbalance, attendance/fatigue variability, and toss variability; future trials with larger samples and ANCOVA/mixed-model analyses are warranted.
