Effect of High Intensity Interval Training (HIIT) on VO2 Max in Young Adult: Literature Review

Abstract

Cardiovascular disease (CVD) is the main cause of death for adults in the world. CVD in the future will be one of the problems that will persist in long term. Someone who has high cardiorespiratory fitness (CRF) and VO2 max has a low risk of developing CVD. One aspect of CVD prevention is exercise to improve cardiorespiratory fitness. High intensity interval training (HIIT) is an exercise that has many benefits, one of which is increasing cardiovascular fitness by increasing VO2 max. With an increase in VO2 max, the risk for CVD will decrease and better prevention is begin at a young age. The purpose of this study is to analyze the effect of High Intensity Interval Training (HIIT) on VO2 max levels in young adult. The research method uses a Literature Review study. Data collection through Pubmed, Science direct, and Google Scholar within the last 10 years. There were 668 articles were obtained which were then screened so that 7 articles with various types of research such as comparative studies, randomized control trials and clinical trials, were suitable to be reviewed. The results showed that High Intensity Interval Training (HIIT) affected in increasing VO2 max. This is related to Reactive oxygen species (ROS) which will later affect the body's adaptive response. High Intensity Interval Training (HIIT) is better in increasing VO2 max compared to other exercise.
