In Indonesia there were many kinds of martial arts and community breathing exercise but the use of breathing exercise for therapy and maintenance toward healthy, fresh still not optimally implemented. 'Starting from this, the research to uncover the role of breathing exercise on the change of beta-endorphin really need to be revealed.
This research aims to reveal the changes in beta-endorphin levels caused by breathing exercise "Satria Nusantara ". The design used was a randomized pretest-posttest group design. A total sample of 15 men. Training is delivered over seven weeks, three limes a week. Samples of blood (serum) taken three times in the beginning before exercise, 45 minutes and 24 hours after the last exercise. Laboratory examination using ELISA (enzyme linked lmunosorbent Assay). Data analysis using t test.
This results showed that average serum levels of pretest of 16.62 ng/ml, 45 minute post exercise at 20.86 nglml and24 hours post exercise at 20.39 ng/ml. After using the t test, found that beta-endorphin levels of 45-minute pretest-posttest increased significantly with p = . 000, and pretest-posttest at 24 hours there was also a significant improvement with p = . 000.
That elevated levels of beta-endorphin 45 minute after exercise was much higher compared with the measurements 24 hours after exercise. The distance of time taking 45 minutes and 24 hours has shown a decrease in levels of beta-endorphin. The decrease shows that there are indications of recovery towards normal.
