Abstract

The police is an agency of the state government whose job is to maintain security, order and public order (arresting people who break the law). The police play a role in maintaining public order and security, enforcing the law, and providing protection, protection and service to the community. To be successful as a police officer, special preparation is required to achieve the desired results. So far, the training program for police candidates has only focused on time-paced running. There has been no variety of interval training developed. Extensive Interval Training is an alternative exercise that police recruits can do to pass the Aptitude Test. The purpose of this study was to identify the effect of extensive interval training in increasing aerobic endurance (VO2max) in prospective police students. Experiments were used in the design of this study. This study used only one experimental group, and the treatment was modified interval training. police subjects are candidates aged 19–21 years who attended 18 sessions of Extensive Interval Training. Coopert’s test (12 minutes run) is the instrument used in data collection. In this study, Kolmogorov sminov was used to calculate data normality to ensure that the sample groups came from the same population. The hypothesis was tested using the SPSS 23 program by comparing the results of the first test with the final test, namely the 12 minute running test. The results of the study proved that there was an increase in the aerobic endurance of POLRI candidates after being given Extensive Interval Training, namely an increase in the percentage of aerobic endurance of police candidates after being given interval training of 10.21%.

Key words: extensive interval training, VO2max
