The COVID-19 pandemic has harmed all sectors, including athletes. Since the COVID-19 pandemic in Indonesia, all activities have been subject to restrictions. The rules of working from home, studying from home, and closing some public facilities make all aspects of this difficult. The athletes' training center is also one of the negatively affected places. Of course, this will impact the decrease in the achievement of athletes due to changes in physical activity, body mass index, and cardiovascular fitness levels. This study aims to determine the correlation between body mass index and cardiovascular fitness levels of volleyball athletes during the COVID-19 pandemic at the Sleman Athlete Training Center, Yogyakarta Special Region of Indonesia. This research is an observational study with a cross-sectional design at the Sleman Regional Athlete Training Center, conducted in September 2021. The sample size is 40 athletes, consisting of 20 male and 20 female athletes. The cardiopulmonary fitness level was measured using a multistage fitness test. The analysis uses the chi-square test to see the relationship between body mass index and cardiovascular fitness level. The results demonstrated no relationship between body mass index and the cardiovascular fitness level of volleyball athletes at the Sleman Athlete Training Center, with a significance value of p=0.484. This study concludes that there is no correlation between body mass index and cardiovascular fitness levels in volleyball athletes at the Sleman Regional Athlete Training Center during the COVID-19 pandemic.
