Abstract

Background: Endorphin is a biological change in molecular physiology that is commonly connected with anxiety. An increase in the level of anxiety is caused by both an increase and a decrease in the number of endorphins that are present in the brain; however, up until this point, it has never been reported that there is a relationship between the level of anxiety and the influence of interval training. Objective: The purpose of this study was to analyze the effect of training interval on endorphin level and anxiety degrees of secaba student soldiers with moderate degrees of anxiety. Methods: The subject of the study was a student soldier of Secaba Rindam III Siliwangi with moderate anxiety. The subject of the study gets information about the objectives and procedures of the study. Subjects who are willing to participate in the study sign informed consent. The next step was that group 1 was given an interval training treatment 3 times a week for 12 weeks and group 2 was given continuous training treatment. Results: The results showed that there was a difference where interval training is better than continuous training against increasing endorphin levels (30.9111.733 vs. 39.6519.956; p=0.043). The degree of anxiety decreased significantly after being given interval training treatment (64.64±3.671 vs. 29.50±4.165; p=0.0001). Similarly, there was a significant difference (p=0.027; p
