Internal Walking Training, Tekanan Darah, Hipertensi LansiaAbstrak
Penuaan sering kali memicu penurunan fungsi fisiologis pada lansia, dengan hipertensi sebagai penyakit tidak menular utama yang semakin memperburuk risiko masalah kardiovaskular. Di Indonesia, prevalensi hipertensi mencapai 34,1% (Riskesdas 2018), dengan angka tertinggi pada lansia di Bantul yang mencatat 83.932 kasus pada tahun 2020. Penelitian ini dirancang untuk menilai efektivitas Internal Walking Training (IWT) dalam menekan tekanan darah sistolik dan diastolik pada lansia penderita hipertensi di Kelurahan Sriharjo, Bantul. Penelitian ini menggunakan quasi-eksperimental dengan desain one-group pre-test post-test, melibatkan 43 responden lansia yang dipilih melalui purposive sampling. Intervensi IWT dilakukan satu kali selama 30 menit, terdiri dari 5 siklus (3 menit jalan lambat diikuti 3 menit jalan cepat), dengan pengukuran tekanan darah menggunakan sphygmomanometer digital sebelum dan sesudah intervensi; analisis data dilakukan melalui uji Wilcoxon Signed Rank Test. Hasil penelitian menunjukkan penurunan signifikan pada tekanan darah sistolik maupun diastolik setelah penerapan IWT. Dengan demikian, IWT terbukti efektif sebagai intervensi nonfarmakologis yang sederhana untuk mengendalikan hipertensi pada lansia.
