The purpose of the present study was to evaluate the relationship between resting blood pressure and maximal oxygen uptake (V̇O2max) and to elucidate the association of different types of sports activity on the resting blood pressure in Japanese young men with a wide range of V̇O2max. The subjects (n=46) consisted of untrained subjects (n=42), judo athletes (n=11), and triathletes (n=11) aged 21 to 35 years. Systolic (SBP) and diastolic (DBP) blood pressures were measured in the sitting position after 5 min of resting, and V̇O2max was directly measured by the Douglas bag method. SBP, DBP, and mean blood pressure (MBP) were negatively correlated with V̇O2max and positively correlated with body weight. A stepwise selective multiple regression analysis for SBP resulted in two significantly correlating variables: V̇O2max and body weight. For DBP and MBP, the analysis resulted in two explaining variables: V̇O2max and body weight. Two independent variables explained 37% of the variation of the SBP, 43% of that of DBP, and 54% of that of MBP. These results indicate that variance in resting blood pressure is partly accounted for by the variance in endurance capacity (i.e., V̇O2max). However, SBP, DBP, and MBP were significantly higher in judo athletes compared with untrained men (P<0.05) when it was compared with the same range of V̇O2max. These results indicate that resting blood pressure is probably influenced with V̇O2max, while the relationship is influenced by the type and intensity of training and other factors.
