Abstract

Kejadian overweight pada wanita merupakan salah satu permasalahan kesehatan yang banyak ditemukan pada usia dewasa. Strength training berperan dalam meningkatkan massa otot, sedangkan pengaturan pola makan membantu mengendalikan asupan energi dan zat gizi. Penelitian ini bertujuan mengidentifikasi perubahan body recomposition pada wanita overweight setelah diberikan program strength training dan pengaturan pola makan di JP GYM Kabupaten Bandung. Penelitian menggunakan desain quasi-experimental dengan pendekatan one group pretest-posttest pada 32 wanita usia 20–45 tahun yang dipilih secara purposive sampling. Data dikumpulkan melalui pengukuran massa lemak dan massa otot menggunakan Bioelectrical Impedance Analysis (BIA) serta asupan energi dan zat gizi makro menggunakan SQ-FFQ dan food record, kemudian dianalisis menggunakan Paired Sample t-test dan Wilcoxon Signed-Rank Test. Hasil menunjukkan kepatuhan strength training sebesar 86,00% dan kepatuhan pengaturan pola makan sebesar 88,78%. Massa lemak menurun 0,556 poin persentase (p=0,001) dan massa otot meningkat 0,425 poin persentase (p=0,001). Asupan energi dan lemak menurun masing-masing sebesar 247,290 kkal (p<0,001) dan 10,791 g (p=0,001), sedangkan asupan protein meningkat 76,813 g (p<0,001) dan asupan karbohidrat menurun 80,597 g (p<0,001). Terdapat perbedaan yang bermakna pada massa lemak, massa otot, dan asupan zat gizi sebelum dan sesudah intervensi. Program strength training dan pengaturan pola makan disarankan tetap dilakukan secara konsisten dengan pendampingan agar perubahan komposisi tubuh dapat terkontrol.
