... : Design of this research is analytical descriptive with the approach of cross sectional, method with the gathering sampel by pusposive, there are found 116 samples from the Medical Student of Tadulako University at entire of year on 2012 which consisted of 40 mans and 76 womans. Measurement of anthropometri by with the body mass index (BMI), while the measurement of corporeal fitness storey by with harvard step test. Relation between of body mass index with the corporeal fitness storey is analysed by the correlation spearman test. Result of Research : At the man subject was found the existence of a weak negative correlation strength between of body mass index with the corporeal fitness storey. It is showing that BMI excelsior of somebody is progressively lower the corporeal fitness storey. p < 0,05 (p=0,041) very having a sense at the belief interval value is 95% and coefficient value of correlation is r =-0,324. At the woman subject was found the existence of a weak negative correlation strength between of body mass index with the corporeal fitness storey. It is showing that BMI excelsior of somebody progressively lower the corporeal fitness storey. p < 0,05 (p=0,02) very having a sense at the belief interval value is 95% and coefficient value of correlation is r =-0,267. At the whole subject was found the existence of a weak negative correlation strength between body mass index with the corporeal fitness storey showing that BMI excelsior of somebody is progressively lower the corporeal fitness storey. It is showing that BMI excelsior of somebody progressively lower the corporeal fitness storey, p < 0,05 (p=0,003) very having a sense at the belief interval value is 95% and coefficient value of correlation r =-0,275. Conclusion : There are found the existence of a weak negative correlation strength between of body mass index (BMI) with the corporeal fitness storey the Medical Student of Tadulako University at entire of year on 2012.
