Balanced Physical Exercise Increase Physical Fitness, Optimize Endorphin Levels, and Decrease Malondialdehyde Levels

Abstract

Background: Physical fitness determines the level of human health. A good physical fitness can be achieved if conducted with a balance and active physical fitness. The aims of this study was to elucidate the effect of balanced physical exercise on physical fitness, endorphin levels, and malondialdehyde (MDA) levels. Methods: This study was a true experimental with pretest-posttest control group design using 24 students of IKIP PGRI Denpasar. Selected samples divided into two groups: the control group given conventional physical training (P0) and the treatment group given balanced physical training (P1). Physical fitness tests was performed using Cooper method and blood sampling was done to evaluate the level of endorphins and MDA before (pre test) and after (post test) treatment of 8 weeks. The data of endorphin and MDA levels were analyzed using independent T test. Whereas, the physical fitness was analyzed using Mann-Whitney U test. Results: Physical fitness of the group given a balanced physical training was significantly higher compare to the group given a conventional physical training (p < 0.05). Balanced physical training was proven to enhance physical fitness as measured by the Cooper method better than conventional physical training. In contrast, the levels of endorphins of the balanced physical training group did not different with the conventional physical training group (p > 0.05). Levels of MDA of balanced physical training group also did not different with the conventional physical training group (p > 0.05). Conclusions: Balanced physical training can maintain physical fitness of people and improve the health and quality of life.

Parameters of lipid and oxidative-antioxidant status in persons aged 18-23 from radiation-contaminated areas under conditions of moderate physical activity

“…At the end of training period a fairly stable level was marked. There was a tendency to gradually reduce the level of MDA during the training period [73].…”

Pelatihan Fisik Sedang Meningkatkan Kadar Vascular Endothelial Growth Factor Dan Stromal Cell-Derived Factor-1 Serum

“…Selain itu, pelatihan fisik yang seimbang dapat meningkatkan mobilisasi stem cell yang dapat berperan sebagai progenitor pada reparasi jaringan yang rusak (Siswanto dan Pangkahila 2014, Zenitalia et al 2018. Mekanisme lainnya yang terlibat dalam efek anti penuaan pelatihan fisik seimbang adalah dengan mempertahankan kadar hormon endorphin dan menurunkan kadar hormon kortisol, dimana kedua hormon ini memiliki efek antagonis dalam pengaturan penuaan akibat kondisi stress (Hill et al 2008, Pangkahila et al 2016. Pelatihan fisik seimbang juga berkaitan dengan peningkatan hormon seks (Hayes et al 2017), mempertahankan fungsi sistem imun (Nieman dan Wentz 2019), dan berefek genetic melalui perpanjangan telomer (Arsenis et al 2017).…”

Efek Olahraga terhadap Kejadian Dismenor Primer pada Siswi Kelas X SMA Negeri 78 Jakarta Barat

“…Latihan fisik menyebabkan reseptor di dalam hipotalamus dan sistem limbik yang berfungsi untuk mengatur emosi menangkap hormon β-endorphin yang dapat dihasilkan setelah seseorang melakukan kebiasaan olahraga. 18 Hasil penelitian terdahulu menunjukkan kesesuaian antara kejadian dismenor dakan meningkat jika kurang olahraga karena oksigen tidak dapat tersalurkan ke pembuluh-pembuluh darah di organ reproduksi yang saat ini terjadi vasokontriksi sehingga menyebabkab timbulnya rasa nyeri. 19 Kebiasaan olahraga merupakan serangkaian aktivitas yang dilakukan secara terstruktur dengan berpedoman pada aturan tertentu yang tidak terikat pada intensitas dan waktunya.…”
