Analisis Teknik Lempar Gt (Glide Technique) Dalam Tolak Peluru: Prinsip Biomekanika, Tahapan Gerak, Dan Implikasinya

Penelitian ini bertujuan untuk menganalisis penguasaan teknik lempar Glide Technique (GT) dalam tolak peluru pada atlet Club PASI Kotam Medan berdasarkan tahapan dan komponen gerak yang menjadi indikator pelaksanaan teknik. Penelitian menggunakan pendekatan kuantitatif deskriptif dengan metode survei. Populasi penelitian berjumlah 30 atlet, sedangkan sampel sebanyak 24 atlet yang ditentukan menggunakan teknik purposive sampling. Pengumpulan data dilakukan melalui lembar penilaian teknik GT yang mencakup starting stance, glide phase, transition/power position, kinetic chain, delivery, release, dan recovery. Setiap indikator dinilai menggunakan skala 1–4, kemudian skor dikonversi ke dalam bentuk persentase dan dianalisis menggunakan statistik deskriptif berupa nilai minimum, maksimum, rata-rata, frekuensi, persentase, dan kategori. Hasil penelitian menunjukkan bahwa penguasaan teknik GT secara keseluruhan berada pada kategori baik dengan rata-rata persentase sebesar 82,96%. Fase glide memperoleh nilai relatif paling tinggi sebesar 86,20% dan termasuk kategori sangat baik. Sementara itu, transition/power position dan recovery memperoleh nilai relatif lebih rendah, masing-masing sebesar 81,25%, meskipun masih berada dalam kategori baik. Temuan ini menunjukkan bahwa atlet secara umum telah menguasai tahapan dasar teknik GT, tetapi masih diperlukan peningkatan pada konsistensi perpindahan menuju posisi tenaga dan pengendalian gerak pada fase akhir. Penelitian ini memberikan gambaran evaluatif mengenai penguasaan teknik GT yang dapat digunakan sebagai dasar pembinaan dan perbaikan teknik atlet.
