Reevaluation of Contribution of Physical Fitness, Body Weight, and Different Sports Activity to Resting Blood Pressure in Young Men

Abstract

The purposes of the present study were to evaluate the relationship between resting blood pressure and maximal oxygen uptake (VO2max) 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 VO2max. The subjects (n = 46) consisted of untrained subjects (n = 24), 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 VO2max was directly measured by the Douglas bag method. SBP, DBP, and mean blood pressure (MBP) were negatively correlated with VO2max and positively correlated with body weight. A stepwise selective multiple regression analysis for SBP resulted in two significantly correlating variables: VO2max and body weight. For DBP and MBP, the analysis resulted in two explaining variables: VO2max 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., VO2max). However, SBP, DBP, and MBP were significantly higher in judo athletes compared with untrained men (P less than 0.05) when it was compared with the same range of VO2max. These results indicate that resting blood pressure is probably influenced with VO2max, while the relationship is influenced by the type and intensity of training and other factors.

Physiological and Fitness Comparison between Young Japanese and American Males.

“…The American blood pressure values were comparable to the data from Sagiv, Rotstein, Watkins, Climor, and Ben-Sira (Sagiv et al, 1992) who reported 119 mm Hg for systolic blood pressure and 73 mm Hg for diastolic blood pressure of young American males. The Japanese values were substantially lower than the data from Kumagai et al (1988) who reported systolic and diastolic blood pressure of young Japanese males at 122 mm Hg and 80 mm Hg respectively.…”
