Hipertensi merupakan salah satu penyakit tidak menular yang banyak terjadi pada lansia dan menjadi faktor risiko utama berbagai penyakit kardiovaskular. Salah satu upaya nonfarmakologis yang dapat dilakukan untuk membantu mengendalikan tekanan darah adalah terapi isometric handgrip exercise. Penelitian ini bertujuan untuk mengetahui pengaruh terapi isometric handgrip exercise terhadap tekanan darah pada lansia dengan hipertensi di Posyandu Cempaka Wilayah Kerja Puskesmas Simpang IV Sipin Kota Jambi Tahun 2026. Penelitian ini menggunakan desain quasi experiment dengan rancangan one group pretest-posttest. Populasi penelitian berjumlah 69 lansia hipertensi dengan sampel sebanyak 15 responden yang dipilih menggunakan teknik purposive Random sampling. Pengumpulan data dilakukan melalui pengukuran tekanan darah sebelum dan sesudah pemberian terapi isometric handgrip exercise selama 5 hari berturut-turut. Analisis data menggunakan uji Paired Sample T-Test dengan tingkat kemaknaan 95% ( = 0,05). Hasil penelitian menunjukkan rata-rata tekanan darah sistolik sebelum intervensi sebesar 154,93 mmHg dan diastolik sebesar 94,53 mmHg. Setelah diberikan terapi, rata-rata tekanan darah sistolik menurun menjadi 132,20 mmHg dan diastolik menjadi 81,87 mmHg. Terdapat penurunan rata-rata tekanan darah sistolik sebesar 22,73 mmHg dan diastolik sebesar 12,67 mmHg. Hasil uji statistik menunjukkan nilai p-value = 0,000 (

Hypertension is a non-communicable disease that commonly occurs in the elderly and serves as a major risk factor for various cardiovascular diseases. One non-pharmacological effort that can be undertaken to help control blood pressure is isometric handgrip exercise therapy. This study aims to determine the effect of isometric handgrip exercise therapy on blood pressure in elderly individuals with hypertension at Cempaka Posyandu within the Working Area of Simpang IV Sipin Community Health Center, Jambi City, in 2026. This study utilized a quasi-experimental design with a one-group pretest-posttest approach. The study population comprised 69 hypertensive elderly individuals, with a sample of 15 respondents selected using a purposive random sampling technique. Data collection was conducted by measuring blood pressure before and after the administration of isometric handgrip exercise therapy for 5 consecutive days. Data analysis was performed using the Paired Sample T-Test at a 95% confidence level (alpha = 0.05). The results showed that the average systolic blood pressure before the intervention was 154.93 mmHg, and the diastolic blood pressure was 94.53 mmHg. After receiving the therapy, the average systolic blood pressure decreased to 132.20 mmHg and the diastolic blood pressure to 81.87 mmHg. There was an average reduction of 22.73 mmHg in systolic blood pressure and 12.67 mmHg in diastolic blood pressure. Statistical test results indicated a p-value = 0.000 (p < 0.05), concluding that isometric handgrip exercise therapy significantly affects the reduction of blood pressure among elderly individuals with hypertension at Cempaka Posyandu within the Working Area of Simpang IV Sipin Community Health Center, Jambi City, in 2026. It is recommended that isometric handgrip exercise therapy be socialized and integrated as an activity program in community health centers, particularly for the elderly, as a non-pharmacological effort to help manage blood pressure.
