Application of exercise methods and body mass index (BMI) has an effect on increasing maximum oxygen consumption

Rationale and purpose The purpose of this study is to determine the application of exercise methods and body mass index has an effect on  increasing maximum oxygen consumption Material and Methods The study involved 62 volunteers aged 20-25 who ran at the amateur level 3 times a week for 40-60 minutes. Thirty-two of the study participants had a body mass index less than 25. 30 participants had a body mass index greater than 25. This research refers to a quantitative approach. This study employed an experimental approach with a 2x2 factorial design. Experiments with factorial design are defined as experiments where factors are crossed with other factors in the experiments carried out. Results According to the research, there is a significant relationship between Body Mass Index and High Intensity Interval Circuit Training (HIICT) when it comes to increasing VO2max. High Intensity Interval Circuit Training (HIICT) with a work-to-rest ratio of 1:3 makes players with a BMI of less than 25 more suitable. High Intensity Interval Circuit Training (HIICT) with a work-to-rest ratio of 1:5 is more suitable for players with a BMI below 25. Conclusions It was found that there is a significant relationship between body mass index and high intensity interval circuit training (HIICT) when it comes to increasing VO2max. High-intensity interval circuit training (HIICT) with a 1:3 work/rest ratio makes participants with a BMI of less than 25 more fit. High-intensity interval circuit training (HIICT) with a work-to-rest ratio of 1:5 is more suitable for participants with a BMI below 25.
