Abstract

Latar Belakang: Aktivitas fisik yang rendah dan peningkatan Indeks Massa Tubuh (IMT) merupakan masalah kesehatan global yang dapat memengaruhi kekuatan otot seseorang. Kekuatan otot merupakan indikator penting kesehatan fungsional pada dewasa muda. Tujuan: penelitian ini bertujuan untuk mengetahui hubungan antara kekuatan otot dengan aktivitas fisik dan IMT pada dewasa muda. Metode: Penelitian ini menggunakan pendekatan kuantitatif menggunakan desain cross-sectional, penelitian ini menyasar mahasiswa Program Studi Fisioterapi Univesitas Kristen Indonesia berusia 18-25 sebanyak 66 sampel. Kekuatan otot diukur menggunakan handgrip dynamometer dengan protocol ASHT, tingkat aktivitas fisik diukur menggunakan modified global physical activity questionnaire (GPAQ), dan status IMT yang dihitung berdasarkan tinggi dan berat badan. Analisis data menggunakan uji koreasi Spearman-rho. Hasil: Terdapat hubungan positif yang signifikan antara kekuatan otot dan aktivitas fisik (p-value 0,020 dan koefisien korelasi 0,286). Sedangkan, hubungan tidak signifikan ditemukan pada hubungan antara kekuatan otot dan IMT (p-value 0,259 dan koefisien korelasi 0,141). Kesimpulan: Aktifitas fisik memiliki korelasi yang lebih kuat terhadap kekuatan otot dibandingkan IMT pada dewasa muda./Background: Low physical activity and increased Body Mass Index (BMI) are global health issues that can affect an individual's muscle strength. Muscle strength is an important indicator of functional health in young adults. Objective: This study aimed to determine the relationship between muscle strength and physical activity and BMI in young adults. Methods: This study used a quantitative approach with a cross-sectional design, targeting 66 students aged 18–25 years from the Physiotherapy Study Program at the Christian University of Indonesia. Muscle strength was measured using a handgrip dynamometer with the ASHT protocol, the level of physical activity was measured using the modified Global Physical Activity Questionnaire (GPAQ), and BMI status was calculated based on height and body weight. Data analysis utilized the Spearman's rho correlation test. Results: A significant positive correlation was found between muscle strength and physical activity (p-value 0.020 and correlation coefficient 0.286). Meanwhile, an insignificant relationship was found between muscle strength and BMI (p-value 0.259 and correlation coefficient 0.141). Conclusion: Physical activity has a stronger correlation with muscle strength compared to BMI in young adults.
