Pengaruh Latihan Interval Intensitas Tinggi Terhadap Peningkatan Kebugaran Kardiorespirasi Pada Pemain Bulutangkis Di SMA Muhammadiyah Tegal

Background: Badminton is a small ball game that requires good cardiovascular endurance especially in single game. One of the training to improve cardiovascular endurance (VO2max) is high intensity interval training (HIIT), basically the method of High Intensity Interval Training (HIIT) is done sprint and jogging in turn. 2 Purpose: This study aims to determine the effect of High Intensity Interval Exercise on increasing VO2max. Method: This research is an experimental research using group pretest posttest design design done in SMA Muhammadiyah Tegal in December 2017 until january year 2018. The sample of this research is students of Extracurricular Exercise of Badminton of SMA Muhammadiyah Tegal which amounted to 28 people, who were given pre and post. This exercise is done for 6 weeks with the frequency of exercise twice a week. At the time of pre measurement is done with Multy-satge fitness test (MFT). Then intervention is done using High Interval High Intensity (HIIT) walk and run. Next post is measured with Multy-stage fitness test. Results: The results showed that in the normality test by using the shapiro-wilk test, the results obtained p = 0.647 so that 0.647> 0.05 then the normal distribution. In the test of influence by using dependent T-test obtained the average value of the test before 30,579 and after 42,271 showed there was an increase before the training was given and after the exercise, with the value p = 0.000. This shows that p is smaller than 0.05 means that in this training it is affected, improved and significant. Conclusion: It can be concluded that the effect of high intensity interval training for 15 minutes to increase VO2max. Suggestion: It is recommended that HIIT training is intensified in badminton sport training process. Suggestions for future researchers in order to monitor physical activity, nutritional status and sleep patterns of samples that will also affect the results of research
