VO2Max is a measure that can be used to assess endurance, which is the body's ability to be able to breathe oxygen optimally during strenuous physical activity. Research results (Zawawi, 2021)in wushu athletes in Kediri city showed that 42.86% of wushu athletes turned out to have (VO2Max) with less category. This study aims to determine the most dominant factors related to the body fitness of Saburai Lampung wushu adolescent athletes. The research design used was cross sectional with a total sample of the population, which was 20 people. Data collection was conducted by means of interviews to determine age, sex, smoking habits, and supplement use, while measurements were used to determine nutritional status, body type, and VO2Max. Bivariate analysis using correlation test Rank Spearman and multivariate analysis using multiple logistic regression tests. The results of this study showed that there were 6 people (30%) wushu athletes who had body fitness with less categories. Then there is a very strong relationship between age and VO2Max (p = 0.007; correlation coefficient = 0.728), there is a strong relationship between nutritional status and VO2Max (p = 0.004; correlation coefficient = 0.655), there is a very strong relationship between smoking and VO2Max (p = 0.009; correlation coefficient = -0.800), and there is a sufficient relationship between body type (somatotype) and VO2Max (p = 0.016; correlation coefficient = 0.480). Sex was not associated with VO2Max (p = 0.160), and supplement use was not associated with VO2Max (p = 0.124). Nutritional status is known to be the most dominant factor associated with VO2Max (p = 0.001; OR = 7.025).
