Hubungan kebugaran jasmani terhadap kemampuan memori jangka pendek pada mahasiswa program studi sarjana kedokteran fakultas kedokteran Universitas Udayana



Abstract

Background: Physical fitness is one aspect that needs to be fulfilled by humans in order to be able to carry out activities without feeling significant fatigue. Short-term memory is a memory storage system with limited capabilities. The educational process requires good memory skills so that a person can receive information that can then be processed according to the individual's needs. Increased physical fitness caused by aerobic exercise has been reported to be able to increase brain perfusion and plasticity in the hippocampal area which then improves memory abilities. This study aims to determine the relationship between physical fitness and short-term memory abilities.

Method: This analytic observational study used a cross-sectional design to evaluate the relationship between the test variables. The research sample was students of the Bachelor of Medicine Study Program, Faculty of Medicine, Udayana University for the academic year 2022/2023 who met the research criteria, and the method of taking was using simple random sampling. Physical fitness is measured by the physical fitness index. Short-term memory ability was assessed by the Modified Harvard Step Test and Digit span test. Data analysis was performed with SPSS v. 20.

Results: A total of 100 students were obtained as research subjects. Most of the subjects had a very good physical fitness index, 33 students (33%) and good short-term memory skills, 37 students (37%). The results of the bivariate analysis showed a significant relationship between the two variables in students of the Medical Faculty Study Program, Faculty of Medicine, Udayana University with a chi-square value (p = 0.02) and a Spearman rank value (p = 0.018).

Conclusion: There was a significant relationship between physical fitness and the short-term memory of the student.

 

Latar Belakang: Kebugaran jasmani merupakan aspek yang berkaitan dengan kesehatan fisik manusia. Memori jangka pendek merupakan sistem penyimpanan memori dengan kapasitas yang terbatas. Adapun proses pendidikan membutuhkan kemampuan memori yang baik. Meningkatnya kebugaran jasmani yang disebabkan oleh olahraga aerob telah dilaporkan mampu meningkatkan perfusi dan plastisitas otak pada daerah hipokampus yang dapat meningkatkan kemampuan memori. Penelitian ini bertujuan mengetahui hubungan kebugaran jasmani terhadap kemampuan memori jangka pendek pada mahasiswa.

Metode: Penelitian ini merupakan studi observasional analitik dengan desain cross sectional untuk melihat hubungan antara variabel uji. Sampel penelitian adalah mahasiswa Program Studi Sarjana Kedokteran Fakultas Kedokteran Universitas Udayana tahun ajaran 2022/2023 yang memenuhi kriteria penelitian, dengan cara pengambilan menggunakan simple random sampling. Kebugaran jasmani diukur dengan indeks kebugaran jasmani berdasarkan Modified Harvard Step Test. Kemampuan memori jangka pendek dinilai dengan dan Digit span test. Analisis data dilakukan dengan SPSS v.20.

Hasil: Sebanyak 100 mahasiswa diperoleh sebagai subjek penelitian. Sebagian besar subjek memiliki indeks kebugaran jasmani yang sangat baik, yakni sebanyak 33 orang (33%) dan kemampuan memori jangka pendek yang baik, sebanyak 37 orang (37%). Analisis bivariat menunjukkan hubungan yang signifikan antara kedua variabel pada mahasiswa Program Studi Sarjana Kedokteran Fakultas Kedokteran Universitas Udayana berdasarkan uji chi-square (p = 0,02) dan rank spearman (p=0,018).

Simpulan: Terdapat hubungan signifikan antara kebugaran jasmani dengan kemampuan memori jangka pendek pada mahasiswa.

Keywords: Digit span test mahasiswa kedokteran kebugaran Jasmani memori jangka pendek Modified Harvard Step Test
