Abstract

Kecepatan renang gaya kupu-kupu sangat bergantung pada kekuatan ekslosif otot tungkai bawah, namun risiko cedera sering kali menurunkan komponen biomotorik tersebut. Penelitian ini bertujuan untuk mengevaluasi efektivitas intervensi fisioterapi dalam meningkatkan kekuatan otot tungkai bawah dan performa kecepatan atlet renang pasca-cedera. Penelitian ini menggunakan desain eksperimental kasus tunggal (single-case experimental design) dengan pendekatan evaluasi pra dan pasca-terapi pada seorang atlet renang gaya kupu-kupu berusia 20 tahun. Subjek mengalami cedera otot betis (strain gastrocnemius) kanan. Intervensi diberikan sebanyak 8 sesi (2 kali seminggu selama 4 minggu) meliputi ultrasound, infrared, stretching, calf raise, eccentric exercise, balance training, dan wall squat. Parameter yang diukur adalah nyeri (VAS), Range of Motion (ROM), kekuatan otot (MMT), fleksibilitas, dan waktu tempuh renang 50 meter. Setelah 4 minggu intervensi, terdapat penurunan nyeri gerak (VAS 8 menjadi 2), peningkatan ROM dorsofleksi (S.15°–0°–30° menjadi S.20°–0°–35°), peningkatan kekuatan plantar fleksi (MMT 3 menjadi 5), peningkatan fleksibilitas (19 cm menjadi 25 cm), serta peningkatan kecepatan renang 50 meter (30 detik menjadi 25 detik). Kombinasi modalitas fisioterapi dan latihan beban eksentrik efektif mengurangi spasme, memicu regenerasi jaringan otot betis, serta mengembalikan kapasitas biomekanika tungkai bawah. Pemulihan komponen fisik ini berkontribusi langsung terhadap optimalisasi daya dorong (propulsive force) atlet saat melakukan dolphin kick. Manajemen fisioterapi komprehensif efektif memulihkan fungsi fungsional dan performa kecepatan atlet renang pasca-cedera ringan.
