摘要：We compared the levels of ventilatory threshold (VT) between subjects with and without pro-teinuria. We used data of 402 men and 413 women who were not taking any medications, aged 20 - 77 years, in this cross-sectional in-vestigation study. Aerobic Parameters at VT i.e. oxygen uptake, work rate and heart rate, and exercise habits were evaluated, which are con-sidered to be cardio respiratory fitness. Pro-teinuria was measured by using urine strip de-vices. Forty three men (10.7%) and 29 women (7.0%) were diagnosed as having the proteinuria (± ≦). There were no significant relationships between proteinuria and exercise habits in both sexes after adjusting for age. Oxygen uptake at VT in subjects with proteinuria was significantly lower than that in subjects without proteinuria after adjusting for age in men. However, such link was not noted in women after adjusting for age (p = 0.9964). Finally, associations were at-tenuated after adjusting for age and exercise habits in both sexes. Among Japanese not tak-ing medications, proteinuria might be a modifi-able factor of VT, especially in Japanese men.
