The aim of this study was to find out the profile of muscle strength on elderly at BPLU Senja Cerah Paniki Bawah. This was a descriptive study with cross sectional design. There were 26 respondents who met the inclusion criteria, consisted of 10 elderly men and 16 elderly women. Respondents were selected by using purposive sampling method. The measurements of the muscle strength were done by using 1 RM method while doing elbow flexion, elbow extension, shoulder flexion, shoulder extension, shoulder abduction, knee flexion, knee extension and dorsoflexion. Data were analyzed manually and computerized then presented in tabular form. The result shows that the average muscle strength in elderly men were greater than women and the average muscle strength of respondents that were included in the age group 60-79 years old were greater than those in 80-99 years.Abstrak: Tujuan dari penelitian ini yaitu untuk mengetahui gambaran kekuatan otot pada Lansia di BPLU Senja Cerah Paniki Bawah. Penelitian ini merupakan peneliltian deskriptif dengan rancangan potong lintang. Responden yang memenuhi kriteria inklusi terdiri dari 26 orang yang terdiri dari 10 orang laki-laki dan 16 orang perempuan. Sampel dipilih menggunakan cara purposive sampling. Kekuatan otot pada lansia diukur dengan menggunakan metode 1 RM yang diukur pada gerakan fleksi siku, ekstensi siku, fleksi bahu, ekstensi bahu, abduksi bahu, fleksi lutut, ekstensi lutut serta dorsofleksi. Data yang sudah didapatkan kemudian dikumpul dan diolah secara manual dan komputerisasi serta disajikan dalam bentuk tabel. Hasil penelitian menunjukkan rerata kekuatan otot responden laki-laki lebih besar dibanding perempuan dan rerata kekuatan responden yang termasuk dalam kelompok umur 60-79 tahun lebih besar dibanding kelompok umur 80-99 tahun. Kata kunci: kekuatan otot, lansia, 1 RM.
Elderly are people who have biological systems changing both functional and structural due to the aging process. They experience a decline usphysical capacity, marked by the decrease. This study aimed to determine the effect of weight training on muscle strength of elderly. This was an experimental study with pre-post test group design. Results and Conclusion: In several movements which are showed a significant p value=0.000 (p<0.005) in muscle strength with elbow flexion, elbow extension, and shoulder extension. A significant value of p=0.001(p<0.005) is obtained on the movement of shoulder flexion, shoulder abduction, left foot flexion, and right foot extension, another results p value= 0.002 (p<0.005) in foot dorsoflexion, and p value 0.003 (p<0.005) on the movements of the left leg extension, leg flexion while dextra obtained significant p value=0.004 (p<0.005). As a conclusion weight training can strengthen the muscle of elderly.Keywords: weight training, muscle strength, elderlyAbstrak: Lansia merupakan orang yang sistem biologisnya mengalami perubahan-perubahan struktur dan fungsi dikarenakan usia yang sudah lanjut. Pada lansia terjadi penurunan kapasitas fisik yang ditandai dengan penurunan massa otot serta kekuatannya yang akan menjadi penghambat dalam melaksanakan aktivitas. Tujuan penelitian ini untuk mengetahui pengaruh latihan beban terhadap kekuatan otot lansia. Penelitian ini bersifat eksperimental dengan rancangan pre-post one group test. Hasil dan simpulan: Hasil penelitian menunjukkan nilai signifikan p=0,000 (p<0,05) pada kekuatan otot dengan gerakan fleksi siku, ekstensi siku dan ekstensi bahu. Nilai signifikan p=0,001 (p<0,05) pada gerakan fleksi bahu, abduksi bahu dan fleksi kaki sinistra, ekstensi kaki dextra, nilai p=0,002 (p<0,005) pada dorsofleksi kaki dan nilai p=0,003 (p<0,05) pada gerakan ekstensi kaki sinistra, sedangkan gerakan fleksi kaki dextra diperoleh nilai signifikan p=0,004 (p<0,05). Pada penelitian ini terdapat pengaruh latihan beban terhadap kekuatan otot lansia.Kata kunci: latihan beban, kekuatan otot, lansia
