Abstract


ABSTRACT: This research is very useful to know exercise to diameter
cardiomyocyte hypertrophy of wistar rat. The experimental method using
experimental laboratories with a succe design randomized the post test
control group only design. Samples were white rattus norvegicus wistar
male rats of 10 males, divided into two groups (K1: Regular Exercise and
K2: Control). Combined treatment with regular exercise frequency 3 times
a week, and moderate 20 minutes / day with an additional 3% of initial
body weight, do at 7:00 pm to 2:00 pm for 8 weeks, and with a 30ºC pool
temperature treatment. Observation of histology of heart muscle as much
as 5 field width with 400x enlargement on microscope randomly selected.
The result of paired T-Test Analysis shows sig = 0,570 <0,01. In
conclusion there was a significant difference between the group of regular
exercise and the control group on the magnification of diameter on left
ventricular heart muscle fibers of wistar rats.
Keyword: regular exercise, hypertrophy myocardial, wistar rats
ABSTRAK: Penelitian ini bertujuan untuk mengetahui pengaruh
signifikan latihan teratur terhadap pembesaran diameter serat otot jantung.
Penelitian experimental laboratories dengan rancangan randomize control
group post test only design menggunakan sampel tikus putih jenis rattus
norvegicus wistar, berjenis kelamin jantan, sebanyak 10 ekor, terbagi
menjadi dua kelompok (K1: Latihan teratur dan K2: Kontrol). Perlakuan
berupa renang dengan frekuensi latihan teratur 3 kali seminggu dan kontrol
tanpa perlakuan, intensitas moderat, dan durasi 20 menit/tikus dengan
tambahan beban 3% dari berat badan awal, dilakukan pada pukul 19.00-
22.00 selama 8 minggu, dan dengan memperhatikan suhu kolam 30ºC.
Pengamatan gambaran histologi otot jantung sebanyak 5 luas lapang
pandang dengan pembesaran 400x pada mikroskop dipilih secara acak.
Hasil analisa Uji-T berpasangan menunjukkan tingkat sig = 0,570 < 0,01.
Kesimpulannya terdapat perbedaan yang signifikan antara kelompok
latihan teratur dan kelompok kontrol terhadap pembesaran diameter pada
serat otot jantung ventrikel kiri tikus wistar.
Kata kunci: latihan teratur, pembesaran otot jantung, tikus wistar
